Sparlo vs Solve Intelligence

This is a factual comparison. Every claim about Solve Intelligence below was verified against solveintelligence.com or a cited third-party source as of August 2026. Where a fact is not verifiable, we write "not published" rather than guessing.

Solve Intelligence builds AI software for patent professionals. Founded by Chris Parsonson, Sanj Ahilan, and Angus Parsonson, it went through Y Combinator in 2023, raised a $12M Series A in April 2025 led by 20VC with participation from Microsoft's M12 and Thomson Reuters Ventures, then a $40M Series B in December 2025 led by Visionaries, taking total funding to $55M.

Its homepage leads with drafting and productivity: "Be 50%+ more productive," for "drafting, prosecution, claim charts, invention harvesting, and more" (solveintelligence.com, as of August 2026). Listed products: invention harvesting, patent application drafting, patent prosecution (office action response drafting), and Charts, a claim-charting product launched with the Series B.

Honest credit:

• Full-lifecycle coverage. Disclosure intake through drafting, prosecution, and claim charts, in one platform.
• Real traction on both sides of the market. Its Series B press reports roughly 400 IP teams, about 60% law firms (including DLA Piper and Perkins Coie) and 40% corporate IP departments (including Siemens), with eight-figure ARR (company-reported figures, IPWatchdog).
• Profitability. The same press release states the company is profitable, which is rare in legal AI and worth noting.
• Enterprise posture. Solve publishes SOC 2 Type 2, ISO 27001, and ISO 42001 on its site, plus GDPR and CCPA compliance statements (solveintelligence.com, as of August 2026).

Sparlo is narrower on purpose. Four concrete differences:

1. Office-action-first analysis. Solve leads with drafting productivity across the lifecycle. Sparlo starts at the office action: it maps each rejection, checks the examiner's characterization of every cited reference against what the reference actually discloses, and ranks the available arguments before anything gets drafted. Analysis first, prose second.

2. Published pricing. Sparlo's rates are public on the pricing page: Attorney $299 per seat per month, Practice $249 per seat per month (3-seat minimum, pooled usage), Firm as a flat annual license with uncapped seats. Solve does not publish pricing on its site (verified August 2026; see next section).

3. Self-serve trial, no demo call. Solve's site is built around a "Request Demo" call to action, with no self-serve signup found as of August 2026. Sparlo's trial is self-serve and can be run entirely on public documents, so you can evaluate it without touching a client file.

4. A governance layer for client files. Sparlo runs on Anthropic's commercial API; nothing you enter trains a model, processed content is subject to 30-day deletion, and processing is US-only. Drafting and draft-review modes run at zero external calls. Every outbound prior-art query is logged per matter, and a client consent pack plus per-matter AI policy controls are included.

As of August 2026, Solve Intelligence does not publish pricing. Its site has no pricing page, and the path to a number runs through a demo request. One third-party comparison estimates roughly $9,300 per user per year (about $775 per user per month), inferred from the stated value of a NAPP member discount, and flags it as an estimate (Patentext, updated July 2026). Treat it accordingly; confirm with Solve directly.

Sparlo's pricing is published in full: $299 per seat per month (Attorney, self-serve), $249 per seat per month (Practice, 3-seat minimum, pooled usage), and a custom flat annual license for firms with seats uncapped.

The USPTO's April 2024 guidance (89 FR 25609) states: "There is no prohibition against using these computer tools in drafting documents for submission to the USPTO. Nor is there a general obligation to disclose to the USPTO the use of such tools." Duties of candor and reasonable inquiry continue to apply to what you file.

The fair test is the same office action through both products. For Solve, request a demo and ask to run your document live. For Sparlo, start the self-serve trial with a published application and a public office action; no client data required. Worked examples on real public patents are at sparloip.com/examples.
