The trailing-behind-a-vessel theme (arguments 1, 2, 4) is the record's center of gravity, but Jayaram's stern-reel disclosure sits in the same record as the examiner's readiest cure for any §103 trailing gap, so counsel may wish to weigh whether the durable distinction lies in the positively recited marine vessel/hull (which Howlin lacks entirely and which Jayaram cannot supply to a §102 rejection) and in the 'multiple separate independently floating structures' feature that distinguishes Jayaram's continuous strip. Several arguments (3 buffers, 5 storage) target features the examiner can plausibly reach on a new rationale from references already in the record (Bersano's shock absorbers, Rikoski's towed array), which counsel may treat as amend-leaning candidates rather than pure argument. Given this examiner's multi-action, interview-receptive pattern, counsel may consider an interview to test claim construction (the intended-use vs. structural-configuration question and the scope of 'buffers') before committing to an argue-only posture on any single limitation.

Howlin is a moored, weathervaning array — it does not disclose floating structures trailed behind a marine vessel (§102 claims 1-4)

Missing elementClaim 1Claim 2Claim 3Claim 4Rebuts: §102 rejection of claims 1, 2, 3, 4

a hull that is shaped to reduce hydrodynamic drag while the multiple floating structures are trailed on a water surface behind the marine vessel; and ... the multiple floating structures are longitudinally positioned and support the solar panel section while trailing the plurality of solar panel sections about the water surface

Howlin is fully grounded and, on its own text, describes a floating photovoltaic array that is MOORED to a single-point mooring buoy and passively 'weathervanes' about that fixed point — not an array trailed on the water behind a moving marine vessel (Howlin Abstract; claim 1 reciting a 'mooring system (30) comprises a single point mooring buoy (32) ... tethered to at least one anchor point (36)'). Per OA2, Howlin's available text 'does not describe a marine vessel that tows or trails the array, nor a system that is trailed on a water surface behind the marine vessel.' The examiner supplies the trailed-behind-a-vessel configuration only through an MPEP § 2114 'structurally capable' inference, not through any affirmative Howlin disclosure, and counsel should weigh whether that clause is a positively recited structural configuration (a §102 gap if so) rather than mere intended use. Counsel should further weigh that a system fixed by mooring lines (34) to anchor points (36) and designed to rotate about a buoy is arguably not even structurally capable of being trailed behind a moving vessel — undercutting the capability inference itself. Because anticipation requires a single reference to disclose every limitation arranged as claimed (MPEP § 2131), this is a candidate dispositive gap for the entire §102 rejection.

  • Howlin claim 1: 'the mooring system (30) comprises a single point mooring buoy (32) connected to the at least one buoyancy element (10) or to the base (5), and at least one mooring line (34) ... tethered to at least one anchor point (36)'
  • Howlin description: 'the array of flotation units 100 automatically or passively rotating downwind or down wave of the single point mooring buoy 32'
  • OA2 (Reference 1 reality check): 'The available text does not describe a marine vessel that tows or trails the array, nor a system that is trailed on a water surface behind the marine vessel.'
  • Office action claim 1 mapping: hull 'cited to read on the claimed ... because the cited hull has a shape structurally capable of reducing hydrodynamic drag while the cited multiple floating structures 10 are trailed ... behind the marine vessel'
MPEP § 2131 — anticipation requires every limitation in a single reference arranged as claimed; the examiner's capability inference implicates MPEP § 2114/§ 2115 (functional/intended-use language), which counsel must address by arguing the clause is a positive structural configuration.

⚠ Risk The examiner will likely reassert that an apparatus claim's 'trailed behind the marine vessel' language is intended use and that Howlin's structure is capable of the recited function (MPEP § 2114). Prosecution-history-estoppel caution: characterizing the invention as specifically 'towed behind a moving vessel' to distinguish Howlin narrows claim scope in the file wrapper and may foreclose broader (e.g., moored) coverage later.

Likely examiner response survives — moderate

For an apparatus claim under §102, an examiner would invoke MPEP § 2114/§ 2115 and characterize 'trailed on a water surface behind the marine vessel' as a statement of intended use/manner of operation that does not structurally distinguish over Howlin. The examiner would argue Howlin's flotation units (100) linked by horizontal elements (8) and flexible joints (9) are structurally capable of being towed, that mooring to buoy (32)/anchor (36) is a temporary use-state rather than a permanent structural feature that forecloses towing, and that the array 'could be' detached and trailed — placing the burden on applicant to show the structure is INcapable of the recited use (In re Schreiber burden-shift).

How to adjust The genuinely contestable point is whether 'trailed behind the marine vessel' is a positively recited structural configuration or mere intended use — a fight counsel can lose under § 2114. A cleaner, harder-to-answer lever hides in the same hook: claim 1 positively recites a marine vessel with a hull 'shaped to reduce hydrodynamic drag,' and per OA2 Howlin discloses no marine vessel or hull at all. Counsel should confirm from the actual office action how (or whether) the examiner mapped a hull/vessel; an outright missing-vessel gap is dispositive for §102 in a way the capability inference is not, and it does not depend on winning the intended-use characterization.

Howlin's flexible joints restrain clashing — it does not disclose impact-absorbing buffers (claim 6)

Mischaracterized referenceClaim 6Rebuts: §103 rejection of claims 5, 6, 7, 8

the multiple solar panel sections have buffers to absorb impact forces during lateral collisions of the separate independently floating sections

The office action maps the claimed impact-absorbing 'buffers' to Howlin's elements 8/9, but Howlin's fully grounded text characterizes element 8 as a 'horizontal element' linking the bases and element 9 as a 'flexible joint,' not as a buffer that absorbs impact during collisions. Howlin affirmatively teaches that its units 'cannot clash with each other as they are restrained in surge, sway, and yaw' — a restraint that PREVENTS lateral clashing rather than a buffer that 'absorbs impact forces during lateral collisions.' Read in its entirety (MPEP § 2141.02), Howlin's disclosed function is the opposite of the recited impact-absorption during collision, which counsel should weigh as a mischaracterization / prima-facie gap for claim 6. (Counsel should separately note that Bersano claim 9 discloses peripheral shock absorbers but was not asserted against claim 6; whether the examiner may bring it in on a new rationale is a distinct consideration.)

  • Howlin description: 'The linking horizontal elements 8 are connected to the bases 5 by flexible joints 9.'
  • Howlin description: 'the sails of the flotation units cannot clash with each other as they are restrained in surge, sway, and yaw'
  • Office action claim 6: 'the multiple solar panel sections ... have buffers 8/9 to absorb impact forces during lateral collisions'
  • OA3 (claim 6 chart): Howlin's restraint 'PREVENTS lateral clashing rather than a buffer that absorbs impact forces during lateral collisions.'
MPEP § 2141.02 — a reference must be considered in its entirety, including teachings that contradict the mapped function; see also MPEP § 2131 for the anticipation-level element requirement carried into the §103 base.

⚠ Risk The examiner may reassert that a flexible joint inherently cushions or that element 8 has structure capable of absorbing impact, or may issue a new rejection importing Bersano's shock absorbers (Bersano claim 9). No estoppel concern beyond confirming what 'buffer'/'absorb impact' means in the specification.

Likely examiner response survives — moderate

Under BRI (MPEP § 2173), an examiner could construe 'buffers to absorb impact forces during lateral collisions' broadly and argue that Howlin's flexible joint (9) inherently cushions/absorbs relative motion between units, so a structure that limits clashing by flexing is a 'buffer.' The examiner may also frame Howlin's statement that units 'cannot clash ... as they are restrained in surge, sway, and yaw' as describing the RESULT of compliant elements that necessarily absorb load, not a teaching away. And Bersano claim 9 (peripheral shock absorbers) sits in the record as a ready new-ground supplement for the buffer function.

How to adjust The function-mismatch reading (prevent clashing vs. absorb collision impact) is defensible under § 2141.02 (reference read in entirety), but it turns on claim construction of 'buffer' and 'absorb impact,' which the examiner can contest under BRI. Counsel should pin the construction — what structure/function the spec assigns to 'buffers' — and weigh that Bersano's admitted shock absorbers make this a candidate for amendment (tie the buffer to disclosed impact-absorbing structure) rather than a pure argument, since the examiner can likely reach the feature on a new rationale.

No asserted reference supplies the trailed-behind-vessel configuration for independent claim 5 (§103 base gap)

Missing elementClaim 5Claim 6Claim 7Claim 8Rebuts: §103 rejection of claims 5, 6, 7, 8

a hull that is shaped to reduce hydrodynamic drag while multiple floating structures are trailed on a water surface behind the marine vessel ... the multiple floating structures are longitudinally positioned and support the solar panel sections while trailing the solar panel sections about the water surface

The §103 rejection of claim 5 rests on Howlin as the base reference, with Bersano brought in only for the wiring-interconnection feature. As established for claim 1, Howlin's fully grounded text describes a moored weathervaning array, not structures trailed behind a marine vessel (OA2, Reference 1; Howlin claim 1 mooring system). Bersano is likewise a set of individually-floating panels juxtaposed into a moored mesh/grid (Bersano claims 12-16, describing peripheral retention means and mooring), and does not supply a vessel-trailed configuration either. Because neither asserted reference affirmatively discloses trailing behind a marine vessel and the examiner supplies it only by the same capability inference, counsel should weigh whether the §103 prima facie case is incomplete as to claim 5 and its dependents 6-8.

  • OA2 (Reference 1): Howlin's text 'does not describe ... a system that is trailed on a water surface behind the marine vessel.'
  • OA2 (Reference 3): Bersano describes 'a solar installation formed from an assembly of multiple such individually-floating panels juxtaposed together into a mesh/grid' with 'peripheral retention means' (Bersano claims 12-16).
  • Office action claim 5 mapping relies on Howlin elements 10 being 'structurally capable of being longitudinally positioned ... while trailing the plurality of solar panel sections.'
MPEP § 2143.01 / § 2141.02 — a §103 rejection must account for every limitation across the combination; a limitation absent from all asserted references (and supplied only by capability inference) is a gap in the prima facie case.

⚠ Risk The examiner will likely repeat the intended-use/capability position and note that claim 5 is an apparatus claim. Prosecution-history-estoppel caution: emphasizing 'trailed behind a moving vessel' as the distinguishing feature narrows the claim scope of record.

Likely examiner response survives — moderate

The strongest comeback is not within the four corners of the current rejection but in the record: Reference 4 (Jayaram) is described in OA2 as disclosing a reel assembly mounted at the stern of a ship deploying a continuous strip of panels 'to extend behind the vessel on or above the water surface' — i.e., the very trailed-behind-vessel configuration the argument says no asserted reference supplies. An examiner (given this examiner's ~3.7 OAs-to-allowance and interview propensity) could issue a new-ground §103 adding Jayaram to Howlin/Bersano, articulating that trailing panels behind a vessel was a known deployment, thereby curing the mapped gap.

How to adjust As to the CURRENT rejection the gap holds — neither Howlin nor Bersano affirmatively discloses trailing behind a vessel and it rests only on the capability inference. But counsel should treat Jayaram as the examiner's readiest cure and pre-position a distinction: claim 5 requires 'multiple floating structures'/'separate independently floating sections' that are 'longitudinally positioned,' whereas OA2 describes Jayaram as a single continuous strip wound on a reel. Weigh whether that separateness/longitudinal-support feature distinguishes Jayaram, and whether amending to sharpen it is preferable to resting on a gap the examiner can fill in the next action.

Conclusory motivation to add Rikoski's storage/retraction to Howlin's large moored offshore array (claims 16-17)

Conclusory rationaleClaim 16Claim 17Rebuts: §103 rejection of claims 16, 17

a storage system ... configured to be stored in the storage system in or on the marine vessel with the plurality of solar panels being configured to be compacted together ... and comprises a retraction mechanism to retract the trailing platform of the multiple solar panels from the water

The §103 rejection's stated motivation — that adding Rikoski's storage system to Howlin 'would have allowed for the apparatus to be stored' — is a candidate for challenge as a conclusory rationale lacking a rational underpinning (MPEP § 2143.01). Rikoski is directed to small autonomous marine vehicles and buoys with a controller/motor that rolls flexibly bendable panels into a housing (Rikoski Abstract; claims 1-2, 5), whereas Howlin is a large, spaced-apart moored offshore array of vertical-panel flotation units tethered to anchor points. Counsel should weigh whether a PHOSITA would have had a reason, beyond hindsight from the applicant's own disclosure, to compact and retract Howlin's fixed, weathervaning array into a housing on a vessel, and whether doing so is consistent with Howlin's principle of operation. The bare assertion that storage is generally desirable does not, standing alone, supply the required articulated reasoning under MPEP § 2143.

  • Office action §103 (claims 16-17): 'it would have been obvious ... to have modified the apparatus of Howlin et al. to include the storage system, as suggested by Rikoski, because it would have allowed for the apparatus to be stored.'
  • Rikoski claim 5: 'the one or more solar panels are flexibly bendable, the one or more solar panels being rolled in the retracted position'
  • OA2 (Reference 2): Rikoski is for 'powering a marine vehicle' with a controller that 'extends and retracts' a solar panel assembly between deployed and stored positions.
  • OA4 combination weaknesses: 'conclusory_motivation (moderate); hindsight_reconstruction (moderate)'
MPEP § 2143 / § 2143.01 — every obviousness rationale requires articulated reasoning with a rational underpinning; conclusory 'would have allowed it to be stored' is attackable, and hindsight drawn only from the applicant's disclosure is impermissible.

Risk The examiner may respond that storability is a well-recognized design incentive (MPEP § 2143 rationale F) and that Rikoski expressly teaches storage of marine solar assemblies, supplying an adequate reason. Note also that claim 17's 'the trailing platform' antecedent-basis defect (below) may need to be resolved before the art argument is fully joined.

Likely examiner response survives — moderate

The examiner has a pointed rebuttal in Rikoski's own text: OA2 notes Rikoski 'references a towed array solar panel assembly (Fig. 10)' and discloses a controller/motor that retracts panels into a housing. The examiner can argue Rikoski is squarely in the towed/marine-solar field (not a distant art), that storing/retracting a deployed marine solar array is a known technique yielding the predictable result of protecting it from weather/transit (MPEP § 2143 rationale C/D), and that this supplies more than a bare 'storage is desirable' statement. Rikoski's towed-array reference blunts both the non-analogous framing and the 'no reason to combine' framing.

How to adjust Counsel should confront Rikoski's Fig. 10 towed-array disclosure head-on rather than characterize Rikoski only as 'small autonomous vehicles/buoys' — that characterization is vulnerable given the record. The stronger residual point is the scale/architecture mismatch (rolling a flexible panel into a housing vs. compacting Howlin's spaced-apart vertical-panel flotation units tethered to anchors) and whether retracting a weathervaning moored array is consistent with Howlin's principle of operation. Weigh pressing the § 2143 articulated-reasoning gap narrowly, and consider whether the storage/retraction claim elements are better secured by amendment tied to the specific compaction mechanism disclosed.

Reconfiguring Howlin to be trailed behind a moving vessel would destroy its weathervaning principle of operation

Destroys principle of operationClaim 1Claim 5Rebuts: §103 rejection of claims 5, 6, 7, 8

the multiple floating structures are ... trailed on a water surface behind the marine vessel

As a fallback to the capability inference, counsel should weigh that Howlin's entire purpose is a passive single-point mooring that lets the array 'weathervane' to shed environmental loads about a fixed buoy and anchor point (Howlin Abstract; claim 1; description of mooring system 30/buoy 32/anchor 36). Trailing the array behind a moving marine vessel — a fundamentally different, non-moored, load-imposing configuration — would rework how Howlin fundamentally functions and would defeat the passive load-shedding that Howlin identifies as its object. Under MPEP § 2143.01, a proposed reading or modification that changes the reference's principle of operation, or renders it unsatisfactory for its intended purpose, does not support the rejection. This reinforces both that Howlin is not structurally 'capable' of the trailed configuration and that any obviousness bridge to it would be improper.

  • Howlin description: 'This allows free rotation of the array of flotation units 100 about a single point (the single point mooring buoy 32) ... results in the array ... automatically or passively rotating downwind or down wave'
  • Howlin background/summary: mooring system 'enables the structure to rotate (for example, like a weathervane) to minimize or shed environmental loads (including wind, wave, and current)'
  • OA4 combination weaknesses: 'destroys_principle_of_operation (moderate); combination_inoperable (moderate)'
MPEP § 2143.01 — a modification cannot change the principle of operation of the reference or render it unsatisfactory for its intended purpose.

Risk The examiner did not expressly propose modifying Howlin into a trailed system (the §102/§103 mappings rely on capability), so the examiner may respond that no modification was proposed and the argument is inapposite. Frame this as supporting the capability/missing-element attack rather than as a stand-alone response.

Likely examiner response fragile — the comeback likely defeats it

This lever is aimed at a target the rejection may not present. 'Changing the principle of operation' (MPEP § 2143.01) polices a proposed MODIFICATION or combination; but for claim 1 (§102) and for the trailing element generally, the examiner supplies the trailed configuration through a § 2114 structural-capability inference, not by proposing to rework Howlin's mooring into a tow. Where no modification of Howlin is proposed, there is no 'principle of operation' being changed to attack — the examiner can respond that capability-to-be-towed does not require destroying the weathervaning design. And if the examiner instead brings in Jayaram, the trailed configuration comes from Jayaram (which is built for stern deployment), so Howlin's principle need not be altered at all.

How to adjust Do not press this as a standalone lever against a capability-based §102 or a Jayaram-sourced §103 — it presupposes a modification the record may not contain. Its real utility is as reinforcement of the rank-1 capability rebuttal (a moored, anchor-tethered array designed to weathervane is arguably not structurally capable of being trailed). Fold it into argument 1 rather than advancing it independently; reserve the full § 2143.01 principle-of-operation argument for any future action in which the examiner actually proposes to modify Howlin's mooring to achieve trailing.

Conclusory motivation to add Bersano's series wiring to Howlin (claims 5-8)

Conclusory rationaleClaim 5Claim 6Claim 7Claim 8Rebuts: §103 rejection of claims 5, 6, 7, 8

wherein the multiple solar panel sections are separate independently floating sections interconnected via wiring to one another

The rejection's motivation for importing Bersano's wiring into Howlin — that it 'would have provided for interconnection of the multiple solar panel sections in series' — is a candidate for challenge as merely restating the added feature rather than supplying an articulated reason a PHOSITA would combine these particular references (MPEP § 2143.01). Counsel should weigh this as a secondary/supporting point, because it is weaker than the trailing missing-element attack: interconnecting floating solar panels via wiring is a comparatively standard teaching (Bersano claim 11 recites a watertight electrical connector), and the examiner may readily supplement the reasoning. This argument is best paired with the rank-2 base-reference gap (Howlin/Bersano not disclosing the trailed-behind-vessel configuration), which is the stronger lever for claims 5-8.

  • Office action §103 (claim 5): 'it would have been obvious ... to have modified the apparatus of Howlin et al. to include the wiring of Bersano et al. because it would have provided for interconnection of the multiple solar panel sections in series.'
  • Bersano claim 11: watertight electrical connector 'permettant le raccordement électrique des cellules photovoltaïques'
  • OA4 combination weaknesses: 'conclusory_motivation (weak)'
MPEP § 2143.01 — a motivation statement must be more than a restatement of the feature being added; see also MPEP § 2143 (rationale must rest on factual findings).

Risk This is a weak lever: the examiner will likely cure any conclusoriness by pointing to the well-known benefit of series interconnection for voltage, and Bersano expressly teaches electrical connection. Do not rely on it alone for claims 5-8.

Antecedent-basis §112(b) rejections of claims 1 and 5 are best resolved by amendment, with a limited construction fallback

Definiteness rebuttalClaim 1Claim 5Rebuts: §112(b) rejection of claims 1, 2, 3, 4, 5, 6, 7, 8, 16, 17

the solar panel section (claim 1 lines 8-9; claim 5 lines 8-9), following 'a plurality of solar panel sections' / 'multiple solar panel sections'

The examiner rejects claims 1 and 5 because 'the solar panel section' lacks a clear antecedent given the earlier recitation of a plurality/multiple 'solar panel sections.' Under the examination standard (BRI plus MPEP § 2173.02 / In re Packard / Ex parte Miyazaki), counsel should weigh whether the scope is nonetheless reasonably certain — i.e., that 'the solar panel section' reads on each of the previously recited sections — but this is a fragile lever because the singular/plural mismatch is a genuine drafting ambiguity that the examiner can reasonably say is amenable to more than one construction. The practical and stronger path for counsel is a conforming amendment (the amendment CONCEPT: make the later reference agree in number with, and clearly point back to, the earlier-introduced sections), which the examiner has expressly indicated would overcome the related objections. Note that a simultaneous §112(b) and §102/§103 rejection here is proper compact-prosecution practice (MPEP § 2173.06(II)), so counsel should not argue the pairing is inconsistent.

  • Office action ¶7 (claim 1): 'As there is more than one previously recited "solar panel section" ... it is unclear as to what "the solar panel section" ... is referring to.'
  • Office action claim 5 objection: 'Amending "the solar panel sections" to "the multiple solar panel sections" would overcome the objection.'
MPEP § 2173.02 / In re Packard / Ex parte Miyazaki — examination definiteness standard (BRI; unclear-term and plural-construction prongs); do NOT cite Nautilus, which is the litigation standard.

Risk The examiner will likely maintain the rejection absent an amendment because the antecedent-basis ambiguity is facially reasonable. Amendment is low-risk here, but counsel should confirm the amended number/reference is consistent throughout claims 1-8, 16-17 to avoid new antecedent issues; watch for any scope narrowing introduced by the conforming amendment.

Antecedent-basis §112(b) rejection of claim 17 ('the trailing platform' / 'the multiple solar panels') — amend-first

Definiteness rebuttalClaim 17Rebuts: §112(b) rejection of claims 1, 2, 3, 4, 5, 6, 7, 8, 16, 17

the trailing platform of the multiple solar panels (claim 17 lines 2-3)

The examiner rejects claim 17 because 'the trailing platform' and 'the multiple solar panels' lack antecedent basis in claim 17 or its parent claim 16, which recites 'a plurality of solar panels' and 'the solar panel section' but never a 'trailing platform.' Under MPEP § 2173.02, counsel should weigh whether the intended referents are reasonably clear from the parent claim, but this is a fragile rebuttal because the specific term 'trailing platform' does not appear in the claim 16/1 chain — an amendment to introduce or conform the terminology is the stronger path. Counsel should coordinate any amendment with the rank-1/rank-2 'trailed behind the marine vessel' arguments, since introducing 'trailing platform' language could bear on claim scope characterization. As with claims 1 and 5, the co-pending §103 rejection of claim 17 does not make the §112(b) rejection improper (MPEP § 2173.06(II)).

  • Office action ¶9-10: claim 17 'recites the limitation "the trailing platform" ... There is insufficient antecedent basis' and 'recites the limitation "the multiple solar panels" ... There is insufficient antecedent basis.'
  • Claim 16 text: recites 'a storage system' and 'the plurality of solar panels'/'the solar panel section' but not a 'trailing platform.'
MPEP § 2173.02 / In re Packard — examination definiteness standard; not Nautilus.

⚠ Risk The examiner will likely maintain the rejection absent amendment. Prosecution-history-estoppel caution: introducing 'trailing platform' terminology to cure the antecedent-basis defect could be read as narrowing the invention toward a specifically towed/trailed configuration; coordinate with the trailing-limitation arguments to avoid inconsistent scope statements in the file wrapper.

Examiner's Characterization of the Cited Art

Note

What each cited reference actually discloses, checked against what the examiner said it teaches — limited to the reference text available to the analysis.

Howlin (US 2026/0021875 A1)

US2026/0021875A1Claim text retrieved

Howlin describes a floating photovoltaic system that is MOORED to a single-point mooring buoy and 'weathervanes' about that point so that environmental loads (wind, wave, current) are passively shed. Each flotation unit (100) carries at least one vertical or near-vertical PV panel (20) mounted on a mast (3) on a base (5), and the base is supported by at least one buoyancy element (10), described in the figures as 'a pair of twin horizontal pipe elements.' Multiple flotation units are spaced apart and linked by horizontal elements (8) via flexible joints (9) to form an array (200) tethered by mooring lines (34) to anchor points (36). The available text does not describe a marine vessel that tows or trails the array, nor a system that is 'trailed on a water surface behind the marine vessel.'

Claim elementExaminer assertsReference disclosesEvidence
a hull that is shaped to reduce hydrodynamic drag while the multiple floating structures are trailed on a water surface behind the marine vesselEach floating structure 10 comprises a hull structurally capable of reducing hydrodynamic drag while trailed on a water surface behind the marine vessel, compared to another shape providing more drag.MischaracterizedHowlin does not describe a 'hull' or trailing behind a vessel; it describes a MOORED, weathervaning system whose buoyancy pipe elements 10 are aligned to 'reduce wave loads by minimizing the area of the buoyancy elements 10 exposed to the oncoming waves,' and the invention 'enables the structure to rotate (for example, like a weathervane) to minimize or shed environmental loads.' The examiner's reading rests on a functional 'structurally capable' inference imposed on a moored buoyancy element; the disclosed context (moored wave-load reduction, not towed hydrodynamic drag) is materially different. Whether a capability argument suffices under § 102 is for counsel.
the multiple floating structures are longitudinally positioned and support the solar panel section while trailing the plurality of solar panel sections about the water surfaceThe floating structures 10 are structurally capable of being longitudinally positioned and supporting the solar panel section while trailing about the water surface.MischaracterizedThe 'trailing ... about the water surface' aspect is not disclosed; Howlin's array is moored and weathervanes about a single-point mooring buoy rather than being trailed. See Summary ('mooring system which enables the structure to rotate ... like a weathervane'). The examiner again relies on a 'structurally capable' inference.
the multiple solar panel sections have buffers to absorb impact forces during lateral collisions of the separate independently floating sections (claim 6)The solar panel sections have buffers 8/9 to absorb impact forces during lateral collisions of the separate independently floating sections.MischaracterizedHowlin identifies 8 as a 'horizontal element' linking bases and 9 as a 'flexible joint,' described for adapting to the wave profile and reducing structural loads — not as 'buffers' for absorbing lateral-collision impacts. The reference further states the units are restrained in surge, sway, and yaw so that 'the sails of the flotation units cannot clash with each other,' i.e., the design avoids collisions rather than buffering them.
Preamble — apparatus for collecting solar energy for a marine vessel (claims 1 and 5)Howlin discloses an apparatus for collecting solar energy for a marine vessel.Not found in available textThe available text describes a system moored to a single-point mooring buoy tethered to anchor points on 'land or on the seabed'; it does not describe a marine vessel that the apparatus serves or is towed behind. Whether the preamble is limiting is a question for counsel.
multiple floating structures coupled to each of the plurality of solar panel sections (pairs of element 10 per unit 100)Multiple floating structures, a pair of 10 per unit 100, coupled to each solar panel section.Partially supported"The buoyancy element 10 shown in the Figures is a pair of twin horizontal pipe elements" positioned beneath the base 5. Howlin calls these buoyancy/pipe elements rather than 'floating structures'; whether a buoyancy pipe element reads on the claimed 'floating structure' is for counsel to weigh.
a bow shaped to displace water as the multiple floating structures are trailed on the water surface (claim 2)The foremost part of each floating structure 10 is a bow structurally capable of displacing water as trailed.Partially supportedHowlin describes aligning the 'smaller end area of the buoyancy element' with the down-wave direction to reduce wave loads, but does not describe a 'bow' or a structure 'trailed on the water surface.' The characterization rests on functional/capability language rather than an affirmative disclosure of a bow for trailing.
catamaran-style structure with dual pontoons connected by the support structure for load distribution (claims 3 and 8)The multiple floating structures (pair of 10 per unit 100) are catamaran-style with dual pontoons 10 connected by support structure 5.Partially supported"The buoyancy element 10 shown in the Figures is a pair of twin horizontal pipe elements" beneath base 5 — twin parallel pipe elements resemble a dual-pontoon/catamaran arrangement. Howlin does not use the term 'catamaran' or 'pontoon'; whether twin pipe buoyancy elements read on 'catamaran-style dual pontoons' is for counsel to weigh.
each of the multiple floating structures are hollow or have a foam filled interior (claim 4)Paragraph [0044] teaches each floating structure 10 as 'pipe elements,' which are hollow structures.Partially supportedThe available text confirms element 10 is described as 'pipe elements' / 'a single or multiple pipe element' (claim 12), but the available excerpt does not expressly state that the pipe elements are 'hollow'; that appears to be the examiner's inference. The specific paragraph [0044] cannot be verified against the available excerpt (which lacks paragraph numbering). The full published paragraph [0044] should be checked.
the multiple solar panel sections are separate independently floating sections (claim 5)The multiple floating structures (pair of 10 per unit 100) are separate independently floating sections.Partially supportedHowlin's flotation units are 'spaced apart' but are 'linked together by horizontal elements 8' via flexible joints 9 and are expressly 'fixed relative to each other in surge, sway, and yaw' (free only in pitch, roll, heave). Whether interconnected units so restrained qualify as 'separate independently floating sections' is for counsel; the examiner's mapping also conflates the floating structures (10) with the 'solar panel sections' recited in the claim.
first and second solar panel sections with floating structures, connected to one another (claim 7)First and second solar panel sections (top and bottom rows of units 100) with floating structures 10 mechanically connected to one another, including bows shaped to displace water as trailed.Partially supportedHowlin discloses an array of multiple flotation units linked by horizontal elements 8 via flexible joints 9, which supports a general 'connected to one another' reading. However, the row-to-row 'first floating structure ... connected to a first floating structure' mapping and the 'bow shaped to displace water as ... trailed' language import the same unsupported trailing/bow characterizations noted above; the specific connection topology asserted should be checked against Figs. 1-4.
a plurality of solar panel sections comprising a plurality of solar panels (units 100 with panels 20)A plurality of solar panel sections at each unit 100 comprising a plurality of solar panels 20 (Fig. 3).Supported"the floating photovoltaic system 1 comprises a plurality of flotation units 100 spaced apart from each other, forming an array of flotation units 100," each mast (3) "configured to accommodate at least one photovoltaic panel 20."

The base 5 further comprises at least one buoyancy element 10 positioned beneath the base 5"; base 5 is 'configured to accommodate at least one photovoltaic panel 20.' Note Howlin labels 5 a 'base,' which is a claim-construction point for counsel.

Rikoski

US2020/0156753A1Claim text retrieved

Rikoski describes systems for powering a marine vehicle with a solar panel assembly that a controller extends and retracts between an extended (deployed) position and a retracted (stored) position, based on sensed conditions or timing. The available text (claims, abstract, and description excerpt) discloses a solar assembly housing that stores the assembly when retracted, flexibly bendable panels that can be rolled/unrolled (and rigid panels 'rolled into and out of a housing'), panels that can be stacked when retracted, and a controller/motor that positions the assembly between the extended and retracted states. It also references a 'towed array solar panel assembly' (Fig. 10) and submersible panel portions.

Claim elementExaminer assertsReference disclosesEvidence
a storage system in or on the marine vessel in which the floating structures/solar panels are stored (claim 16)Rikoski discloses the storage system allows for the solar panel assembly to be stored in the housing (¶[0008]).SupportedClaim 2: "solar assembly housing arranged to store the solar panel assembly while in the retracted position"; Description: "The solar assembly housing may be integrated with a housing of the vehicle or may be included within the housing of the vehicle."
the storage system comprises a housing and a retraction mechanism to retract the platform of the solar panels from the water (claim 17)Rikoski teaches solar panels may be rolled into and out of a housing (¶[0009]), which necessarily includes a retraction mechanism.SupportedDescription: "rigid solar panels may be rolled into and out of a housing"; Claim 5 (rolled/unrolled between retracted and extended positions); and Claim 12: "the controller includes a motor arranged to position the solar panel assembly into at least one of the extended and retracted positions" — the available text affirmatively describes a motor-driven mechanism rather than requiring the 'necessarily' inference.
retract a 'trailing platform' of the multiple solar panels from the water (claim 17)The rolling into/out of a housing reads on retracting a trailing platform of the multiple solar panels from the water.Partially supportedRikoski teaches extending/retracting the solar panel assembly and a housing (Claims 1, 2, 5, 12) and a "towed array solar panel assembly" (Fig. 10 description); however, the available text does not use the specific term 'trailing platform,' and the disclosed context is autonomous marine vehicles/buoys/AUVs rather than a platform trailed behind a distinct marine vessel — the 'trailing platform' framing derives largely from the base (Howlin) combination, a point for counsel to weigh. Note also claim 17's own antecedent-basis objection flagged in the office action regarding 'the trailing platform.'

The available text (French abstract and claims 1-17) describes a floating solar panel having a monobloc floating structure carrying photovoltaic cells, for use in marine or other aquatic environments, and a solar installation formed from an assembly of multiple such individually-floating panels juxtaposed together into a mesh/grid. The claims include a watertight electrical connector for connecting the photovoltaic cells (claim 11), attachment means and cable/rope/strap systems for mooring multiple panels to one another (claims 10, 13, 14), and a peripheral retention means incorporating a static converter that conveys the electricity produced to a remote electrical grid (claim 17). The full specification and figures (including any Fig. 17) are not part of the available text.

Jayaram

US2025/0023506A1Claim text retrieved

Jayaram (US 2025/0023506 A1) discloses a solar panel system with a flexible support structure (e.g., collapsible hose or sheet material) supporting solar panels, at least part of which is fillable with a fluid for buoyancy/weight/rigidity adjustment. The available text describes the system being retractable into a compact configuration (e.g., wound onto a reel) for storage and deployable into an expanded configuration for power generation. In an embodiment, a reel assembly is mounted at the stern of a ship so the continuous strip of panels is deployed to extend behind the vessel on or above the water surface.

Claim elementExaminer assertsReference disclosesEvidence
Pertinent prior art cited in the Conclusion (not applied in any rejection): 'retractable solar panel sections trailing marine vessel (see Fig. 2)'Jayaram teaches retractable solar panel sections that trail a marine vessel, with a pin-cite to Fig. 2.Partially supportedRetractability is supported (Claim 10: retractable into compact configuration / deployable into expanded configuration; Claim 18). The 'trailing marine vessel' aspect is supported by the description that the reel is 'mounted at the stern allowing the continuous strip to be deployed from the reel ... such that it extends behind the ship 20.' The 'see Fig. 2' pin-cite is imprecise on the available drawing list — Fig. 2 is described as 'a side view of FIG. 1' (the solar panel system), whereas the ship/stern-trailing embodiment is associated with Figs. 3-5 (Fig. 3 being 'a side view of a ship on which the solar panel system is installed'); the description does, however, refer to installation on a ship as 'illustrated in FIG. 2 to 5.' For counsel to weigh the figure discrepancy.

Claim 1 — §102 (Howlin)
Status glyphClaim elementStatusDisclosure / notesLocation
a plurality of solar panel sections comprising a plurality of solar panelsHowlinDisclosedHowlin discloses plural flotation units (100), each carrying PV panels (20), which the examiner maps to the 'plurality of solar panel sections.' Caveat for counsel: Howlin's panels are 'vertical or near vertical' PV panels mounted on masts/sails, not the flat/upward-facing arrangement suggested by the pending disclosure; the claim as worded does not recite orientation, so this reads onto Howlin under a broad construction.Howlin, Fig. 3; Howlin, claim 1 ('at least one vertical or near vertical photovoltaic panel (20)'); Howlin, claim 14 ('An array (200) comprising a plurality of the flotation units (100)')
multiple floating structures coupled to each of the plurality of solar panel sections, wherein each floating structure comprises a hull that is shaped to reduce hydrodynamic drag while the multiple floating structures are trailed on a water surface behind the marine vesselHowlinArguably disclosedThe examiner maps the buoyancy elements (10, twin horizontal pipes) to 'floating structures' and argues the pipe shape is 'structurally capable of reducing hydrodynamic drag' — a functional-capability reading (MPEP 2114). Two points for counsel to weigh: (1) whether a horizontal 'pipe element' is fairly a 'hull' shaped to reduce drag; and (2) the 'trailed on a water surface behind the marine vessel' clause — OA2 records that Howlin's available text 'does not describe a marine vessel that tows or trails the array,' because Howlin is a MOORED, single-point-mooring 'weathervaning' array (claim 1; Abstract). The trailing configuration is supplied only by the examiner's capability inference, not by Howlin's actual disclosure. See also missing-element findings.Howlin, Fig. 1-3; Howlin, description ('The buoyancy element 10 shown in the Figures is a pair of twin horizontal pipe elements'); Howlin, claim 12 ('single or multiple pipe element')
a support structure connected with each of the multiple floating structures and the solar panel sectionHowlinDisclosedBase (5) connects the buoyancy elements (10) and the panels, reading on 'support structure.' Note the §112(b) rejection: 'the solar panel section' (singular) lacks antecedent basis given 'a plurality of solar panel sections' in line 3 — this indefiniteness is a separate track for counsel and may affect how the limitation is construed.Howlin, Fig. 1-3; Howlin, claim 1 ('mounted on a mast (3) and supported on a base (5), wherein the base (5) further comprises at least one buoyancy element (10)')
the multiple floating structures are longitudinally positioned and support the solar panel section while trailing the plurality of solar panel sections about the water surfaceHowlinArguably disclosedExaminer again relies on 'structurally capable of' language for 'longitudinally positioned' and 'trailing.' Contestable for counsel: Howlin's units are held by flexible joints and restrained in surge/sway/yaw about a mooring buoy, not longitudinally trailed behind a moving vessel. The 'trailing ... about the water surface' language ties back to the moored-vs-trailed distinction flagged in the element above.Howlin, Fig. 1-4; Howlin, description (array weathervanes about single point mooring buoy 32)
Claim 2 — §102 (Howlin)
Status glyphClaim elementStatusDisclosure / notesLocation
a bow shaped to displace water as the multiple floating structures are trailed on the water surfaceHowlinArguably disclosedExaminer maps the 'foremost part' of buoyancy element (10) to a 'bow' and argues structural capability to displace water. For counsel: Howlin does not describe any foremost portion as a bow or as drag-/wave-directed; the passage explaining wave-load reduction is about aligning buoyancy elements 'down wave' of the mooring buoy, i.e., a moored orientation, not a bow that displaces water while trailed behind a vessel.Howlin, Fig. 1-3; Howlin, description ('a pair of twin horizontal pipe elements')
Claim 3 — §102 (Howlin)
Status glyphClaim elementStatusDisclosure / notesLocation
the multiple floating structures are catamaran-style structure with dual pontoons connected by the support structure for load distribution of the solar panel sectionHowlinArguably disclosedThe 'pair of twin horizontal pipe elements' plausibly reads on 'dual pontoons,' with base (5) as the connecting support structure — a reasonable mapping. For counsel: 'catamaran-style' and 'for load distribution' are the only qualifiers; whether Howlin's twin pipes (sized for buoyancy of a vertical sail) meet a 'catamaran-style ... load distribution' reading is a modest argument at best.Howlin, Fig. 1-3; Howlin, description ('The buoyancy element 10 shown in the Figures is a pair of twin horizontal pipe elements'); Howlin, claim 1 ('base (5)')

Status glyphClaim elementStatusDisclosure / notesLocation
each of the multiple floating structures are hollow or have a foam filled with an interior of the floating structureHowlinDisclosedClaim 4 is stated in the alternative ('hollow OR ... foam filled'), so disclosure of hollow pipe elements satisfies it. Pipe elements are ordinarily hollow. Caveat: the office action pins this to Howlin ¶[0044], and that specific paragraph text is not in the provided excerpt; the pipe-element teaching in claim 12 and the description supports the 'hollow' branch independently.Howlin, claim 12 ('single or multiple pipe element'); Howlin, description ('a pair of twin horizontal pipe elements'); Office action cites Howlin ¶[0044] (paragraph text not present in provided excerpt)

interconnected via wiring to one anotherHowlin, BersanoArguably taughtBersano is FULLY GROUNDED (claims retrieved), and its claim 11 discloses a watertight electrical connector for connecting the PV cells. HOWEVER, per OA2 the specific teaching the examiner relied upon — 'wiring 24' depicted in 'Fig. 17' interconnecting separate independently floating sections — is NOT in the available Bersano text (spec/figures not provided). For counsel: (1) verify whether Bersano actually shows wiring interconnecting SEPARATE FLOATING SECTIONS to one another (as opposed to connecting cells within a single panel per claim 11) before relying on any distinction; and (2) separately weigh the §103 combinability rationale — Howlin is a moored weathervaning array while the pending claims recite a vessel-trailed configuration.Bersano, claim 11 ('au moins un connecteur électrique (11-711), étanche permettant le raccordement électrique des cellules photovoltaïques'); Bersano, claim 17 (peripheral retention means incorporating a static converter conveying electricity to a remote grid); Office action cites Bersano Fig. 17 / wiring 24 (figure not present in provided text — per OA2)
Claim 6 — §103 (Howlin in view of Bersano)
Status glyphClaim elementStatusDisclosure / notesLocation
the multiple solar panel sections have buffers to absorb impact forces during lateral collisions of the separate independently floating sectionsHowlin, BersanoArguably taughtPotential mischaracterization for counsel: the office action labels Howlin's elements 8/9 as 'buffers to absorb impact forces during lateral collisions.' Howlin's own text describes element 8 as a 'horizontal element' that links bases and element 9 as a 'flexible joint,' and expressly states the units 'cannot clash with each other as they are restrained in surge, sway, and yaw.' That is a mechanism for PREVENTING clashing by restraint, not a 'buffer' that 'absorbs impact forces during lateral collisions.' Bersano claim 9 does disclose shock absorbers ('absorbeurs de chocs (106, 206)') at the panel periphery, though the office action did not assert Bersano for this limitation — a point counsel may raise as to whether the record supports the buffer feature and, if so, on what rationale. Howlin is fully grounded; see missing-element findings.Howlin, Fig. 1-3 (horizontal element 8, flexible joint 9); Howlin, description ('linked together by horizontal elements 8 which connect the individual bases 5', 'connected to the bases 5 by flexible joints 9'); Howlin, description ('the sails ... cannot clash with each other as they are restrained in surge, sway, and yaw')

a first floating structure of the first solar panel section is connected to a first floating structure of the second solar panel section, and a second floating structure of the first solar panel section is connected to a second floating structure of the second solar panel sectionHowlin, BersanoArguably taughtExaminer maps 'first/second solar panel sections' to top/bottom rows of units 100 and the corner floating structures as connected. Howlin does disclose inter-unit connection via horizontal elements 8 and flexible joints 9, so the general 'connected to one another' concept is present. For counsel: whether Howlin's array geometry maps to the specific first-to-first / second-to-second pairing is a factual read of Howlin's figures (figures not fully reproduced in the provided text).Howlin, Fig. 1-4; Howlin, description (units 100 'linked together by horizontal elements 8', 'connected to the bases 5 by flexible joints 9')

a storage system, wherein the multiple floating structures and the solar panel section are configured to be stored in the storage system in or on the marine vessel with the plurality of solar panels being configured to be compacted together and disposed in the storage systemHowlin, RikoskiTaughtRikoski (fully grounded) plainly discloses a storage/housing system for a marine solar assembly and compaction (stacking/rolling) when stored. The contestable point for counsel is the §103 COMBINATION, not the individual teaching: Howlin is a moored, single-point-mooring weathervaning array with vertical-sail PV, whereas Rikoski is a vessel-mounted extend/retract system — counsel may weigh whether a POSITA would combine them and whether the stated motivation ('to allow the apparatus to be stored') is supported when Howlin's base structure is a large moored array of masts/sails. OMISSION NOTE (8-claim cap): Claim 8 is omitted because its 'catamaran-style skids with dual pontoons' limitation restates the catamaran/dual-pontoon feature charted at claim 3. Claim 17 is omitted because its storage-housing/retraction teaching parallels this claim 16 analysis (Rikoski claim 2 / ¶[0009] rolled into and out of a housing = retraction mechanism); note additionally that claim 17 carries its own §112(b) rejection — 'the trailing platform' and 'the multiple solar panels' lack antecedent basis in claims 17/16 — a separate indefiniteness track for counsel.Rikoski, claim 2 ('solar assembly housing arranged to store the solar panel assembly while in the retracted position'); Rikoski, claim 3 (housing integrated with / included within vehicle housing); Rikoski, claim 6 (panels 'stacked in the retracted position'); Rikoski, Abstract / ¶[0008]-[0009] (extend/retract between deployed and stored positions)

Elements not shown by the cited art (3)

  • Claim 1 — “the multiple floating structures are ... trailed on a water surface behind the marine vessel (recited in the hull limitation and again in the longitudinal-positioning/'trailing ... about the water surface' limitation)”: Howlin is the sole asserted reference and is fully grounded. Per OA2, Howlin's available text 'does not describe a marine vessel that tows or trails the array, nor a system that is trailed on a water surface behind the marine vessel'; Howlin is a MOORED, single-point-mooring array that passively 'weathervanes' about a mooring buoy (Howlin claim 1; Abstract; description of mooring system 30/buoy 32/anchor 36). The examiner supplies the 'trailed behind the marine vessel' configuration only through an MPEP 2114 'structurally capable' inference, not through any affirmative Howlin disclosure. For counsel to weigh whether this clause is a positively-recited structural limitation (a §102 prima-facie gap if so) or mere intended use — and, given the moored/anchored design, whether Howlin's structure is even capable of being trailed behind a moving vessel.
  • Claim 5 — “the multiple floating structures are ... trailed on a water surface behind the marine vessel (hull limitation and 'trailing the solar panel sections about the water surface')”: Same basis as the claim 1 finding. Howlin (the base reference for the §103 rejection of claim 5) is a moored weathervaning array and, per OA2, its text does not describe trailing behind a vessel; Bersano is asserted only for the wiring-interconnection feature and does not supply a vessel-trailed configuration either (Bersano describes juxtaposed panels moored in a mesh, claims 12-16). No asserted reference affirmatively discloses the trailed-behind-vessel configuration; it rests solely on the examiner's capability inference — for counsel to weigh.
  • Claim 6 — “buffers to absorb impact forces during lateral collisions of the separate independently floating sections”: Howlin is the only reference asserted for this limitation and is fully grounded. Howlin's actual disclosure characterizes element 8 as a 'horizontal element' linking bases and element 9 as a 'flexible joint,' and states the units 'cannot clash with each other as they are restrained in surge, sway, and yaw' — i.e., a restraint that PREVENTS lateral clashing rather than a 'buffer' that 'absorbs impact forces during lateral collisions.' On the provided Howlin text, the recited impact-absorbing buffer function is not disclosed — a mischaracterization / prima-facie-gap candidate for counsel. (Note: Bersano claim 9 discloses peripheral shock absorbers, but Bersano was not asserted against claim 6; whether that could be brought in on a new rationale is a separate consideration.)

Rejection Map

§112(b)Indefiniteness — claims 1, 2, 3, 4, 5, 6, 7, 8, 16, 17

Multiple antecedent basis deficiencies. Claim 1 recites 'the solar panel section' (line 8-9) but previously introduces 'a plurality of solar panel sections' (line 3), making it unclear which solar panel section is referenced; dependent claims 2-4 and 16 rejected for dependency. Claim 5 similarly recites 'the solar panel section' (line 8-9) after introducing 'multiple solar panel sections' (line 3), creating the same ambiguity; dependent claims 6-8 rejected for dependency. Claim 17 recites 'the trailing platform' (line 2) and 'the multiple solar panels' (lines 2-3), neither of which has antecedent basis in claim 17 or its parent claim 16.

§102Anticipation — claims 1, 2, 3, 4

HowlinUS2026/0021875A1

Howlin anticipates claims 1-4 under 102(a)(2). For claim 1: plurality of solar panel sections with solar panels mapped to units 100 with panels 20 (Fig. 3); multiple floating structures mapped to pairs of elements 10 per unit 100 (Fig. 1-3); hull shaped to reduce hydrodynamic drag mapped to hull of each 10, argued to be structurally capable of reducing drag compared to another shape; support structure mapped to element 5 connected with floating structures 10 and solar panel section at unit 100; longitudinal positioning and trailing capability mapped to structural capability of elements 10. For claim 2: bow of each floating structure 10 mapped to foremost part, argued to be structurally capable of displacing water. For claim 3: catamaran-style structure with dual pontoons 10 connected by support structure 5. For claim 4: hollow floating structures based on paragraph [0044] teaching elements 10 as 'pipe elements' which are hollow structures.

§103Obviousness — claims 16, 17MPEP §2143(G)

HowlinUS2026/0021875A1RikoskiUS2020/0156753A1

Howlin anticipates claim 1 as discussed above but does not disclose a storage system with a housing and retraction mechanism. Rikoski teaches a storage system for a marine solar energy apparatus where solar panels may be rolled into and out of a housing (¶[0009]), which necessarily includes a retraction mechanism. Rikoski discloses the storage system allows for the solar panel assembly to be stored in the housing (¶[0008]). Motivation to combine: it would have allowed for the apparatus to be stored.

§103Obviousness — claims 5, 6, 7, 8MPEP §2143(G)

HowlinUS2026/0021875A1BersanoFR2968070A1

For claim 5: Howlin discloses multiple solar panel sections (units 100), multiple floating structures (pairs of 10 per unit 100), hulls shaped to reduce drag, support structure 5, longitudinal positioning, and separate independently floating sections, but does not disclose interconnection via wiring. Bersano teaches multiple separate independently floating solar panel sections 101 interconnected via wiring 24 (Fig. 17) to provide series connection. Motivation to combine: it would have provided for interconnection of the multiple solar panel sections in series. For claim 6: Howlin discloses buffers 8/9 to absorb impact forces during lateral collisions. For claim 7: Howlin discloses first and second solar panel sections (top and bottom rows of units 100) with floating structures connected to one another. For claim 8: Howlin discloses catamaran-style skids with dual pontoons 10 connected by support structure 5.

Obviousness Framework

Field of endeavor
Apparatus for collecting solar energy on the water for a marine vessel — specifically floating photovoltaic panel arrangements supported on floating structures that are trailed (towed) on the water surface behind a marine vessel, and their storage/deployment and interconnection.
PHOSITA
For argument purposes (a proposed construction for counsel to adopt or adjust, not a factual finding): a person with a bachelor's-level education in mechanical, marine, or naval-architecture engineering (or equivalent experience), familiarity with floating/offshore structures and hydrodynamics (drag, buoyancy, hull/pontoon design), and working knowledge of photovoltaic module mounting, electrical interconnection, and deployment/storage mechanisms for marine equipment. This person would be aware of both moored floating-solar installations and towed/deployable marine solar arrangements.A construction for argument — not asserted as fact.

Note for counsel: on the second (reasonably-pertinent) prong Howlin is contestable — per the OA2 reality check Howlin is a MOORED array that 'weathervanes' about a single-point mooring buoy to shed environmental loads, and 'The available text does not describe a marine vessel that tows or trails the array.' The inventor's problem (trailing a solar platform behind a moving vessel) is arguably a different problem than Howlin's (passively shedding loads on a fixed mooring), but same-field status is enough to make it analogous.
Rikoski (US 2020/0156753 A1)AnalogousSame field of endeavor — solar power generation for marine vehicles with deployable/retractable solar panel assemblies (see Abstract; FIELD 'generating electrical power for marine vehicles'). It expressly references a 'towed array solar panel assembly' (Fig. 10 per OA2), which is reasonably pertinent to the inventor's trailing/deployment/storage problem.
Bersano (FR 2968070 A1)AnalogousSame field of endeavor — floating solar panels for a marine/aquatic environment and installations formed by juxtaposing multiple individually-floating panels (see Title/Abstract; claims 1, 12). Reasonably pertinent to the electrical-interconnection aspect the examiner invokes (claim 11 recites a watertight electrical connector for the photovoltaic cells).
Jayaram (US 2025/0023506 A1)AnalogousListed in the Conclusion as prior art made of record 'and not relied upon.' Same field of endeavor — a retractable solar panel system deployed from a reel at the stern of a ship to extend behind the vessel on the water surface (Abstract; description of stern-mounted reel). Included here for completeness; it is not part of any § 103 combination in this office action, so no combination analysis follows.

Claims 16-17 rejected under § 103 as unpatentable over Howlin in view of Rikoski. Howlin is relied on as anticipating base claim 1; Rikoski is added for a 'storage system' with a housing and a retraction mechanism (examiner cites Rikoski ¶[0008]-[0009], panels 'rolled into and out of a housing').

Howlin + Rikoski

Motivation asserted It would have been obvious to add Rikoski's storage system to Howlin's apparatus 'because it would have allowed for the apparatus to be stored.'

  • Destroys principle of operationmoderate

    Per OA2, Howlin's principle of operation is a permanently MOORED array that 'weathervanes' about a single-point mooring buoy tethered by mooring lines (34) to seabed anchor points (36) to passively shed wind/wave/current loads. A storage system that retracts and stows the array in a housing 'in or on the marine vessel' (claim 16) is, on this record, in tension with Howlin's fixed-mooring architecture — reworking Howlin into a stowable, vessel-carried unit may change how the primary reference fundamentally functions (MPEP § 2143.01). For counsel to weigh.

  • Combination inoperablemoderate

    Rikoski's storage mechanism the examiner cites is rolling flexible/rigid panels 'into and out of a housing' (¶[0009]), which presupposes rollable/compactable panels. Howlin's units carry 'vertical or near vertical' PV panels (20) mounted on a mast (3) on a base (5) with rigid buoyancy pipe elements (10) — structures not shown in the record to be rollable or compactable. Whether Rikoski's rolling-into-a-housing storage is operable when applied to Howlin's masted vertical-sail units is contestable (MPEP § 2143.01). For counsel to weigh.

  • Conclusory motivationmoderate

    The articulated reason — 'it would have allowed for the apparatus to be stored' — restates the desired result (storage) rather than explaining why a PHOSITA would have applied Rikoski's specific rolling-housing storage to Howlin's moored, masted array with a reasonable expectation of success (MPEP § 2143, § 2143.02). Counsel may argue the reasoning lacks a rational underpinning tied to Howlin's actual structure; the examiner may respond that KSR permits a concise rationale. For counsel to weigh.

  • Hindsight reconstructionmoderate

    The § 103 rejection stands on Howlin anticipating base claim 1, but OA2 states 'The available text does not describe a marine vessel that tows or trails the array, nor a system that is trailed on a water surface behind the marine vessel.' The examiner supplied the claimed 'trailed on a water surface behind the marine vessel' function through 'structurally capable' reasoning rather than an actual Howlin teaching. Counsel may argue the trailing-behind-a-vessel concept is read into Howlin only with knowledge of the applicant's disclosure (MPEP § 2143.01). Note this is also a claim-construction/BRI question (whether 'shaped to reduce hydrodynamic drag while trailed behind the marine vessel' is a mere capability or an affirmative structural/functional requirement) that remains fully open for counsel. For counsel to weigh.

  • Otherweak

    Claim 17's added limitations ('the trailing platform' and 'the multiple solar panels') are separately rejected under § 112(b) for lack of antecedent basis, and the § 103 mapping of these terms via Rikoski depends on how they are ultimately construed/amended. The interaction between the § 112 indefiniteness and the § 103 mapping is a housekeeping point for counsel to reconcile in any response. For counsel to weigh.

Claims 5-8 rejected under § 103 as unpatentable over Howlin in view of Bersano. Howlin is relied on for the base structure of claim 5 (multiple solar panel sections, floating structures, drag-reducing hull, support structure, separate independently floating sections); Bersano is added only for the added limitation that the sections are 'interconnected via wiring to one another,' the examiner citing 'wiring 24 depicted Fig. 17' interconnecting 'floating solar panel sections 101.' Dependent claims 6-8 rely on Howlin alone.

Howlin + Bersano

Motivation asserted It would have been obvious to add Bersano's wiring to Howlin 'because it would have provided for interconnection of the multiple solar panel sections in series.'

  • Othermoderate

    The specific evidentiary basis the examiner cites for Bersano — 'wiring 24 depicted Fig. 17' interconnecting sections '101' — is not verifiable on the record provided. Per OA2, for Bersano 'The full specification and figures (including any Fig. 17) are not part of the available text.' The Bersano text of record (claims 1-17) supports the general concept of interconnection (claim 11 recites a watertight electrical connector for connecting the photovoltaic cells; claims 13-14 recite cable/rope/strap attachment of panels), but the examiner's precise Fig. 17 / element 24 / element 101 mapping cannot be confirmed against the available record. Counsel should verify the exact Bersano disclosure before relying on or conceding this mapping. For counsel to weigh.

  • Hindsight reconstructionmoderate

    As with the claims 16-17 rejection, the base claim 5 rests on Howlin, but OA2 states the Howlin text 'does not describe a marine vessel that tows or trails the array, nor a system that is trailed on a water surface behind the marine vessel.' The claim 5 requirements — hull 'shaped to reduce hydrodynamic drag while multiple floating structures are trailed on a water surface behind the marine vessel' and floating structures that 'support the solar panel sections while trailing the solar panel sections' — were supplied via 'structurally capable' reasoning rather than an affirmative Howlin teaching. Counsel may argue the trailing function is imported by hindsight (MPEP § 2143.01); the underlying capability-vs-structure claim-construction/BRI question remains fully open. For counsel to weigh.

  • Othermoderate

    Claim 6 depends on the Howlin-alone mapping of 'buffers 8/9 to absorb impact forces during lateral collisions,' but per OA2 Howlin's element 8 is a 'horizontal element' linking units and element 9 is a 'flexible joint' — described in Howlin as reducing structural loads by adapting to the wave profile, not as impact buffers for lateral collisions. Whether elements 8/9 read on the claimed 'buffers to absorb impact forces during lateral collisions' is a mapping question counsel may contest; note Bersano separately discloses peripheral shock absorbers ('absorbeurs de chocs' 106/206, claim 9), which the examiner did not rely on for claim 6. For counsel to weigh.

  • Conclusory motivationweak

    The motivation ('would have provided for interconnection ... in series') states a generic benefit of series wiring and is arguably conclusory as to why a PHOSITA would add it to Howlin — whose units are already physically linked by horizontal elements (8) with flexible joints (9) — with a reasonable expectation of success (MPEP § 2143, § 2143.02). This weakness is comparatively weaker because electrical series interconnection of adjacent PV modules is a well-known, predictable step; counsel should weigh it accordingly. For counsel to weigh.
