Solve Intelligence Raises £30m Series B to Build the AI Platform for Patents

Solve Intelligence, the London-founded AI platform for intellectual property professionals, has raised £30m in a Series B round co-led by Visionaries and 20VC, bringing its total funding to £40m. Existing investors Thomson Reuters and Y Combinator increased their ownership stakes in the company, while Operator Collective and an exceptional group of angel investors also participated — including the founders of Tinder, Canva, Deel, Ironclad, Cleo, Hugging Face, Pigment and Higgsfield, alongside Kevin Johnson, who founded Quinn Emanuel's IP litigation practice. The round arrives just months after the company closed a £9m Series A, underscoring the speed at which IP teams worldwide are adopting AI-native workflows.

The global patent industry is a sprawling, high-stakes ecosystem valued at over $200bn, yet it remains dominated by time-consuming manual processes. In-house legal teams and outside counsel both face acute capacity constraints when managing prosecution, continuations, office action responses and freedom-to-operate analyses across large portfolios. The burden of documentation and correspondence has historically limited the volume and quality of work that even the most experienced patent attorneys can handle, creating bottlenecks that slow innovation and increase costs for technology companies of all sizes.

Solve Intelligence addresses this gap by embedding legal and technical intelligence directly into the tools patent professionals already use, including deep integration with Microsoft Word. Its platform supports every stage of the patent lifecycle — from invention harvesting and application drafting to prosecution correspondence, continuation filings and divisional applications. Customers report time savings of between 60% and 80% on drafting workflows while maintaining or improving quality. Over 400 IP teams across six continents now use the platform, including law firms DLA Piper and Perkins Coie, and in-house teams at Siemens and Avery Dennison.

With Series B capital, Solve Intelligence is launching Charts, a new product extending the platform into litigation and portfolio analysis. Charts enables legal professionals to generate and analyse infringement and invalidity claim charts, map standard-essential patents, conduct freedom-to-operate and clearance reviews, and perform portfolio-level comparisons across thousands of documents. The product is designed with full citation support and exposed AI reasoning, addressing the transparency expectations of leading law firms and regulated institutions. Solve is also opening offices in New York and Munich to deepen on-the-ground support as North America already accounts for over 60% of its customer base.

The pace of growth since the Series A has been striking: the average number of weekly actions per user increased by 265%, and annual recurring revenue grew more than tenfold to reach an eight-figure sum. Visionaries' Rob Lacher described Solve as having a genuine shot at becoming the AI-native system of record for the entire patent lifecycle. 20VC's Paul Bonnet, who also led the Series A, doubled down by co-leading this round — a further signal of conviction in the team of AI researchers, patent attorneys and software engineers building what they describe as the operating system for IP.
