Solve Intelligence Takes Total Funding to $55M with Series B Round to Build AI for Patents, and Launches New Claim Charting Product

Solve Intelligence, the AI platform for the $200B+ patent industry, has raised $40M in Series B funding and is launching a new product for generating patent claim charts.

Solve’s Series B comes just months after its $12M Series A, and brings total funding to $55M. Since last year, annual recurring revenue has grown more than tenfold to reach eight figures. The company is profitable, and has generated more cash than it has raised since inception.

More than 400 IP teams across six continents now use Solve Intelligence. Around 60% of customers are law firms, including DLA Piper and Perkins Coie, and 40% are corporate IP departments such as those at Siemens and Avery Dennison. ‘When we looked at Solve, they were so far above what other people are doing in terms of their technical expertise and the problem they’re trying to solve,’ said DLA Piper partner Larissa Bifano. ‘That’s why we went with Solve.’

The company sells its AI software to both in-house and outside counsel teams across the US, Europe, and other regions, positioning Solve as a collaborative platform for everyone involved in the patent process.

Founded in 2023 by CEO Dr. Chris Parsonson, CTO Angus Parsonson, and Chief Research Officer Dr. Sanj Ahilan and based in San Francisco (US) and London (UK), Solve Intelligence is used for patent preparation and prosecution. Customers rely on the platform for collecting ideas from inventors, drafting patent applications, responding to office actions, handling continuations and divisionals, and coordinating global patent filings. The software supports all major technical domains, from life sciences with biological sequences and chemical structures to software and hardware. ‘We focus on patent work in the life sciences and chemical arts’ said Richard Timmer, Senior Patent Agent at Brown Rudnick. ‘We tested multiple tools in this space. Solve was head and shoulders above the others.’

Solve customers are reporting significant efficiency and quality gains. ‘I can draft a full nonprovisional application at similar quality to what I normally draft but with 60-80% time savings’, said Britten Sessions, Principal at Zilka-Kotab. ‘Solve has led to a 3x in speed while maintaining amazing quality’ added Joel David Briscoe, IP Advisor at Panoramix. Since the Series A earlier this year, the average number of actions performed per user per week has increased by 265%.

A key reason for Solve’s growth and widespread adoption has been its focus on keeping customer data secure and confidential. ‘Those of us in the IP profession appreciate how Solve addresses security concerns upfront in its product development, and not only as an afterthought’ wrote the Special Assistant Attorney General for Colorado, Josh Snider, in a recent LinkedIn post.

Solve’s team has built proprietary AI software specialized for patents and fully compatible with Microsoft Word by combining AI researchers from institutions such as the University of Cambridge, Oxford, UCL, and Imperial College London with US and European patent attorneys from top firms including Hoffmann Eitle, Quarles & Brady, Dentons, Reddie & Grose, Fish & Richardson, Carpmaels, and D Young.

Alongside the Series B, Solve Intelligence is introducing ‘Charts’, a product aimed at patent litigation and high-volume IP analysis. Charts can generate a wide range of customizable claim charts, including invalidity and standard-essential patent charts, freedom-to-operate and clearance analyses, infringement mappings, claim construction analyses, and portfolio-level reviews. It can also help legal professionals extract insights from thousands of documents. Firms and companies using Solve can encode their know-how and expertise into the AI. They use Solve to build proprietary, repeatable, and reusable AI styles and templates that can be shared across their organization. Solve also includes full citation support and exposed AI reasoning to maximize transparency and trust in the output.

The round was led by Visionaries with existing investor 20VC co-leading and significantly increasing its stake. Other existing investors Thomson Reuters and Y Combinator also increased their ownership, with Operator Collective (led by founder Mallun Yen, former Vice President of Worldwide Intellectual Property and Deputy General Counsel at Cisco) and others participating. Angel investors include the founders of Tinder, Canva, Deel, Ironclad, Base44, Cleo, Hugging Face, Pigment, and Higgsfield, as well as Kevin Johnson, who founded Quinn Emanuel’s IP litigation practice.Comments from the lead investors:

“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.”– Robert Lacher, Founder, Visionaries

“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, 20VC
