Solve Intelligence Raises $40M Series B to Build AI for Patents and Launches Charts

As reported by Sifted, Tech Funding News, Artificial Lawyer, Law360 and Law.com, we are excited to announce that we have raised our $40M Series B, taking our total funding to $55M.

This round comes just months after our $12M Series A. It’s a reflection of how quickly the IP industry is adopting Solve Intelligence. We are becoming the platform for in-house and outside counsel IP teams to collaborate across every part of the patent process.

Solve Intelligence Raises $40M Series B to Build AI for Patents and Launches Charts

Expanding Solve Intelligence’s product and global presence

We have raised this round to double down on two things.

First, we’re broadening our platform to go beyond patent drafting and prosecution.

Up to now, 400+ IP teams across 6 continents use Solve Intelligence for invention harvesting, patent application drafting, continuations, divisionals, office actions responses, and more.

Today, with this Series B round, we’re launching our new Charts product. Solve Intelligence can now help legal professionals with freedom-to-operate and clearance work, infringement and validity analysis, standard-essential patents (SEP) mapping, patent litigation, and more. 

Our goal is simple: if it touches patents, you should be able to do it faster, better, and more collaboratively in Solve Intelligence.

Second, we’re expanding our global footprint.

We’re already working with IP teams across the US, Europe, and beyond. With our Series B round, we’re expanding our presence with new offices in New York City and Munich, growing our on-the-ground support for customers in both regions.

We’ll continue to grow our team of AI researchers, patent attorneys, and software engineers to build the go-to platform for every part of the patent process.

Launching Charts: AI for claim charts and patent analysis

Our new Charts product helps IP teams generate and analyze:

  • Infringement and invalidity claim charts
  • Standard-essential patent (SEP) mappings
  • Freedom-to-operate and clearance reviews
  • Portfolio-level comparisons and thematic analyses across thousands of documents

Customers can encode their firm or company-specific know-how into Solve Intelligence, creating reusable AI styles, workflows, and templates that reflect how they practice. Charts includes full citation support and exposed AI reasoning to maximize transparency and trust in the output.

We’re building Charts so that patent attorneys, patent litigators, transaction teams, and in-house IP leaders can tackle work that was previously too time-consuming or expensive to do at scale and to improve the quality of their charting work.

Built for security, quality, and real-world patent workflows

Our growth has been driven not just by what Solve Intelligence can do, but how it does it:

Security and confidentiality first: From day one, we’ve treated confidentiality as a non‑negotiable requirement. Our architecture, deployment model, and product decisions are designed to meet the expectations of leading law firms, corporates, and public institutions.

Specialized AI for patents: We build AI systems that are deeply tuned to patent language, legal standards, and technical detail across software, hardware, life sciences, chemistry, and more.

Tight integration with existing tools: We meet IP teams where they work today, including deep workflows around Microsoft Word and established patent processes, rather than asking them to reinvent everything at once.

Customers report up to 60–80% time savings on drafting while maintaining or improving quality. Since our Series A, the average number of actions performed per user per week has increased by 265%, as teams bring more of their workflows into Solve.

Building the operating system for patents

We started with patent drafting and prosecution. We’ve expanded into invention harvesting, collaboration between in-house and outside counsel, and now claim charting and portfolio analysis with Charts.

Over the next 5 years, we believe the vast majority of in-house and outside counsel IP teams will collaborate on platforms like Solve for every part of their patent workflows. Inventors and R&D teams will interface with IP counsel through systems that are AI-native, transparent, and secure by design.

Our goal is for Solve Intelligence - shaped by patent professionals - to be the core software layer that powers how innovation is captured, protected, and commercialized.

To our customers: thank you for trusting us with your most important work.

To the IP community: we’re just getting started.

The round was co-led by Visionaries and existing investor 20VC. Other existing investors Thomson Reuters and Y Combinator also increased their ownership, with others participating.

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.’

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.

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.’

Finally, 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.’

Marbury Law sees 3x-4x efficiency gain from using Solve Intelligence

Key Insights

  • AI adoption requires proof. Bob and his team tested multiple tools before committing, and only moved forward once they saw quantifiable results.
  • 3 to 4x efficiency gains changed the business case. By tracking his own drafting time, Bob demonstrated that AI-enabled workflows made fixed-fee work viable at partner rates.
  • Demonstration drives adoption. Live drafting sessions, client transparency, and side-by-side cost comparisons created full buy-in from both clients and colleagues.
  • Integrated chat removes friction. Keeping research, drafting, and revisions inside one contextual workspace eliminated copy-paste workflows and saved significant time.
  • Context is a force multiplier. AI performs best when it understands the full invention disclosure, file history, and drafting materials in one place.
  • Speed expands strategic value. Faster drafting didn’t just save time - it enabled better coverage, stronger enablement, and real-time responsiveness to client needs.

About Marbury Law

The Marbury Law Group is a premier mid-size, full-service intellectual property and technology law firm in the Washington, D.C. area, with additional strength in commercial law, litigation, and trademark litigation. Recognized by Juristat as a top 35 law firm nationwide and holding Martindale-Hubbell’s AV® Preeminent™ Peer Review Rating, Marbury serves clients ranging from Fortune 500 companies and mid-size technology businesses to high-tech startups and inventors. Its practitioners bring unusually wide-ranging experience, including former technology executives, government R&D managers, startup founders, in-house counsel, “big-law” attorneys, USPTO patent examiners, and judicial clerks. 

Marbury delivers “big-law” service with the flexibility and personal attention of a smaller firm, pairing high-quality work with efficient, budget-aware billing. Based near the USPTO, the firm has drafted and prosecuted thousands of U.S. and foreign patent applications and trademarks, and advises on IP strategy, diligence, and licensing. Formed in 2009 through the merger of two established practices (with roots dating back to 1994), the firm takes its name from Marbury v. Madison (1803), the landmark Supreme Court case that established judicial review.

Introduction

When we sat down with Bob Hansen for this conversation, we knew it would be grounded in both legal depth and real-world business experience. Bob is a founding partner of The Marbury Law Group and has extensive experience across patent prosecution, litigation, licensing, portfolio strategy, and complex IP transactions. But what makes his perspective particularly compelling is that he also brings 20 years of real-world experience as an engineer, program manager, and business executive in Fortune 50 companies and start-ups. He understands firsthand how innovation moves from idea to product, and how intellectual property law fits into that journey.

That dual lens is exactly why we wanted to have this discussion. Bob evaluates technology not just as a patent attorney, but as someone who has managed engineering teams, navigated acquisitions and divestitures, raised capital, and built businesses. When someone with that background says AI has been transformative and backs it up with measurable 3 to 4x efficiency gains, it’s worth listening.

Introducing Solve Review: A Practical Guide to AI-Powered Patent Review

Patent drafting doesn’t end when the first draft is complete. In many ways, the most important work begins at review.

Jurisdictional compliance, internal style alignment, claim clarity, sufficiency of disclosure, and formal requirements. Each aspect of drafting applications must be carefully checked before filing. Yet a thorough review is time-intensive, difficult to standardize, and hard to scale across teams and large portfolios, especially when up against a tight deadline.

Enter Solve Review

With Solve Review, practitioners can run structured, customizable AI-powered reviews in minutes rather than hours, while maintaining transparency, collaboration, and full control over the output. 

Teams using Solve Review report dramatically, with multi-pass manual reviews that previously took three to four hours completing in a fraction of the time

Key benefits

  • AI-powered patent reviews in minutes
  • Each review is fully customizable
  • Save your reviews as templates, run multiple reviews per application
  • Full transparency of working out and results
  • Resolve issues detected by Solve Review with AI
