Solve Intelligence £35m to automate patent workflows and chart claims with AI
This article covers Solve Intelligence, a legaltech startup, closing a £35m ($40m) Series B to expand its AI platform for patent professionals and launch a new product, Charts. The move aims to support in-house and outside counsel and IP teams by automating patent drafting, analysis and portfolio-level workflows.
Solve Intelligence, a legaltech startup, has closed a £35m ($40m) Series B to expand its AI platform for patent professionals and launch a new product called Charts. The funding — which brings total capital raised to £41.3m ($55m) after a £9m Series A earlier this year — underlines growing demand for specialised AI tools that help in-house and outside counsel manage patent workflows more efficiently.
Why it matters
Patent work remains labour intensive and fragmented across law firms, corporate IP teams, and litigation specialists. Solve Intelligence says its platform addresses that by automating drafting and analysis across multiple stages of the patent lifecycle. The Series B and the Charts launch signal broader momentum for AI in legaltech, and reflects increasing interest from legaltech investors in tools that can scale traditionally manual IP tasks.
Inside the product
Solve Intelligence began with drafting and prosecution features and now supports a wider set of patent workflows. The company reports more than 400 IP teams across six continents use its platform for invention harvesting, drafting patent applications, continuations, divisionals, and office action responses.
Charts, the new product, is aimed at analytical tasks legal teams typically avoid at scale because they are time consuming or expensive. Features include:
- generation and analysis of infringement and invalidity claim charts
- mapping of standard-essential patents (SEPs)
- freedom-to-operate and clearance reviews
- portfolio-level comparisons and thematic analysis across thousands of documents
- full citation support and exposed AI reasoning for transparency
Solve Intelligence says customers can encode firm- or company-specific know-how into reusable AI styles, workflows, and templates. The company emphasises security and confidentiality in its architecture and highlights integrations with existing tools, including deep workflows around Microsoft Word. It reports customers see up to 60–80% time savings on drafting and that actions per user per week have increased by 265% since the Series A.
The firm is also expanding geographically, opening new offices in New York City and Munich and hiring AI researchers, patent attorneys, and engineers to support product growth.
Who are the investors?
The Series B was co-led by Visionaries and returning investor 20VC. Existing backers Thomson Reuters and Y Combinator increased their stakes, and Mallun Yen and her firm Operator Collective participated. The round also includes a wide group of angel investors, among them founders of Tinder, Canva, Deel, Ironclad, Base44, Cleo, Hugging Face, Pigment, Higgsfield, and Trouva, plus Kevin Johnson, who founded Quinn Emanuel’s IP litigation practice.
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, said:
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.
Rob Lacher, founder of Visionaries and who co-led the round, said:
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.
Paul Bonnet, General Partner at 20VC, who led the last Series A round and who doubled down by co-leading this Series B, said:
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.

Founder perspective
Solve Intelligence was founded by a team including Chris, Angus, and Sanj. The company frames its roadmap as building an “operating system” for patents: a single, AI-native layer that captures invention inputs, supports prosecution and litigation analysis, and becomes the system of record for IP work. The product strategy leans on domain-specialised models tuned to patent language and legal standards across software, hardware, life sciences, chemistry, and other technical areas.
The bigger picture
The raise and product expansion sit at the intersection of two trends: increasing adoption of AI in legal services and a push for enterprise-grade, secure platforms that can be integrated into existing corporate and firm workflows. For IP teams, the economics of outsourcing detailed charting and portfolio analysis are changing as AI lowers cost and time barriers.
This story also reflects cross-border demand for legaltech: Solve Intelligence is scaling in the US and Europe, with new offices in New York City and Munich to support multinational clients. As regulation and professional guidance around AI in legal practice continues to evolve in the UK and EU, firms and corporate counsel will be weighing confidentiality, explainability, and compliance alongside efficiency gains — a dynamic that will shape how legaltech products like Solve are used.
