Solve Intelligence has raised $40 million in Series B financing to expand its AI platform for patent work and to support the launch of Charts, a new product aimed at claim charting and large-scale patent analysis. The round was co-led by Visionaries and existing investor 20VC, with Thomson Reuters and Y Combinator increasing their ownership. Operator Collective, led by former Cisco IP executive Mallun Yen, also participated, alongside other backers and a group of angel investors that includes founders of several high-profile technology companies, according to the company and third-party coverage. The angel investors include the founders of Tinder, Canva, Deel, Ironclad, Base44, Cleo, Hugging Face, Pigment, Higgsfield, Trouva, and many others, as well as Kevin Johnson, who founded Quinn Emanuel’s IP litigation practice.
The funding brings the company’s total capital raised to $55 million and follows a $12 million Series A earlier in 2025, according to the company and multiple reports.
Solve Intelligence is positioning itself as a collaboration platform for in-house IP teams and outside counsel across the patent lifecycle, including invention harvesting, application drafting, continuations and divisionals, and office action responses. The company says more than 400 IP teams across six continents use its product, and it has emphasized tight workflow integration with tools such as Microsoft Word, alongside security and confidentiality controls designed for law firm and corporate environments.
The financing is tied closely to Solve’s expansion beyond drafting and prosecution into claim charting, litigation support, and high-volume analysis. The newly launched Charts product is designed to generate and analyze infringement and invalidity claim charts, standard-essential patent mappings, freedom-to-operate and clearance reviews, and portfolio-level comparisons across large document sets. Solve says Charts also provides citation support and “exposed” AI reasoning to increase traceability for legal teams evaluating its outputs.
Solve and its investors have framed the opportunity around modernizing labor-intensive patent workflows, where teams often rely on spreadsheets and manual review processes. In its announcements and related reporting, Solve has cited customer-reported efficiency gains, including claims of 60% to 80% time savings on drafting and a significant increase in product usage since its Series A round.
Geographically, the company said the Series B will also fund expansion in the United States and Europe, including new offices in New York City and Munich, and continued hiring across AI research, patent law, and software engineering roles.
KEY QUOTES:
“After decades in patents as a founder, in-house leader, IP attorney, and now investor, I had an almost unrealistically high bar. But after meeting with dozens of startups, I kept coming back to Chris and his team. They’re not just technically exceptional – they’ve built an AI platform patent attorneys genuinely trust and rely on.”
Mallun Yen, former Vice President of Worldwide Intellectual Property and Deputy General Counsel at Cisco and who joined the round with her firm Operator Collective
“We have deep respect for how Chris, Angus, and Sanj have built Solve into the category leader in the US and Europe, with more than 60% of customers already stateside. The depth of their product is remarkable, and we believe Solve has a real shot at becoming the AI-native platform for intellectual property — the Copilot for IP law — powering every stage of the patent lifecycle across enterprises, law firms, and inventors globally. Solve can unify a fragmented ecosystem into one workflow and data layer that becomes the system of record for how patents are created, prosecuted, and managed.”
Rob Lacher, founder of Visionaries and who co-led the round
“The team at Solve Intelligence is nothing short of exceptional. They have gone from strength-to-strength this year: their product velocity is truly unmatched, and it shows in the customer love they receive, and in the numbers. We could not be more excited to support them again, as they create the OS for IP.”
Paul Bonnet, General Partner at 20VC, who led the last Series A round and who doubled down by co-leading this Series B
