Patlytics Raises $40M as AI Drives a Simultaneous Surge in Patent Filings and IP Litigation

The AI wave sweeping through professional services has largely bypassed patent law; not because the need isn’t there, but because the domain resists the generalist tools that have worked elsewhere. A single poorly managed patent portfolio can expose a company to a decade of competitive vulnerability, and the workflow required to avoid that outcome spans invention disclosure, prosecution, claim charting, infringement analysis, and portfolio triage each demanding a precision that broad-purpose legal AI cannot match. Patlytics was built to close that gap, offering the only end-to-end AI platform purpose-built for the entire patent lifecycle, from invention harvesting through litigation support and portfolio management. The platform now serves more than 40% of the Am Law 100 including Quinn Emanuel, Foley & Lardner, and Susman Godfrey alongside corporate IP teams at companies like Canon, Rivian, and Xerox, with practitioners reporting an 80% reduction in project time and more than $30K saved per claim chart. That traction, built in under two and a half years, reflects a moment when AI-driven patent filing and IP litigation are both rising simultaneously, squeezing IP professionals from both sides.

AlleyWatch sat down with Patlytics Cofounder and CEO Paul Lee to learn more about the business, its future plans, recent funding round, and much, much more….

Who were your investors and how much did you raise?

We recently closed a $40M Series B led by SignalFire, with participation from N47, Myriad Venture Partners, Relativity, Alumni Ventures, Antiportfolio Ventures, and BAM Corner Point. Total funding now stands at approximately $65M — raised in less than two and a half years.SignalFire was the right partner for this moment. We wanted more than a capital infusion, but a true partner to fuel our next phase of growth. SignalFire brings infrastructure, relationships, and deep domain experience across the legal tech ecosystem.Among other participants in this round, we also brought on the former member of the Global Executive Management Committee at Kirkland & Ellis, and Relativity, the market leader in e-discovery. Patlytics is the first startup that Relativity ever invested in.

Tell us about the product or service that Patlytics offers.

Patlytics is the only AI platform purpose-built for the entire patent lifecycle, from invention harvesting and patent application drafting to infringement analysis, invalidity contentions, transactional due diligence, and portfolio management.The mission from day one has been to eliminate inefficiencies across the full IP lifecycle: from invention, through prosecution and drafting, to licensing, defense, offense, and maintenance. What makes us different architecturally is that we built it ground-up as an end-to-end platform.The result: 80% reduction in project time, $30,000+ saved per claim chart, and 15+ hours recovered per patent application — all without sacrificing accuracy.

What inspired the start of Patlytics?

I spent a decade in venture capital evaluating thousands of companies. Patent work kept surfacing as the highest-stakes, most time-intensive enterprise workflow,and the most underserved by software. IP professionals were still doing manual, fragmented work across point solutions that only did so much.When AI changed the premises around what software could do for law, we saw a very clear opening. Today, over 40% of the AmLaw 100 runs on Patlytics, alongside some of the world’s most innovative companies, including Canon, Rivian, Xerox, Asahi Kasei, and TaylorMade.

How is Patlytics different?

Patent work is categorically different. It is not a subset of legal work; it is a company’s most valuable asset, its moat.Drafting, prosecution, search, infringement and invalidity analysis, claim charting, portfolio management, litigation, licensing – each discipline demands deep domain precision that generalist models cannot replicate. Patlytics is the only end-to-end AI platform for IP.

What market does Patlytics target and how big is it?

AI is driving an explosion in IP creation and IP litigation simultaneously.The companies building the most consequential technology in the world are now filing patents at high rates, facing infringement exposure they’ve never navigated before, and discovering that IP licensing can become a primary revenue stream. At the same time, AI-assisted inventions are entering examination queues faster than examiners can process them. Cross-jurisdictional disputes are also rising, especially in Europe.Patlytics is the platform that a Chief Legal Officer, General Counsel, Head of IP, law firm attorney, or any team responsible for an organization’s patent portfolio reaches for to run their entire workflow — across top law firms and large and innovative companies across all industries, including semiconductor, pharma, software, auto, chemicals.The market opportunity is large. Every company building in AI is either creating IP at scale, defending against someone else’s, or both.We’re in the center of that tailwind.

What’s your business model?

We’re an AI platform used by enterprises and SMBs. Law firms and corporate IP teams license Patlytics to run their entire patent workflow, from first invention disclosure through litigation and portfolio management.We started with the Am Law 100 and once we had a critical mass there, penetration into mid-sized and smaller firms followed naturally.

The ROI case has been concrete and immediate: 80% reduction in project time, $30,000+ saved per claim chart, and 15+ hours recovered per patent application.But efficiency is only part of the story. We’re also helping firms outright win business, as well as optimize non-billable work, and go deeper on the cases that matter.When you’re operating in a domain where a single patent can define a company’s competitive position for decades, speed and precision aren’t operational metrics.

How are you preparing for a potential economic slowdown?

Our value proposition gets stronger in a downturn, IP teams under budget pressure don’t have the luxury of slow, expensive outside counsel for every claim chart or invalidity analysis.Patlytics lets a lean team do more with less, at higher quality, in less time, without sacrificing the precision that patent work demands. That’s not a nice-to-have when margins compress. That’s essential infrastructure.And frankly, IP litigation doesn’t slow down in a recession. If anything, companies lean into assertion and defense more aggressively when growth slows, protecting what they’ve built and monetizing what they own.

What was the funding process like?

Disciplined. We’ve raised on results. Nearly 1,000% year-over-year revenue growth.An 18x expansion in our customer base, with an intention to reach thousands of customers by year’s end.Every round has been preempted — we have never had to go looking for capital. Those numbers created real urgency on the investor side, and they spoke for themselves.

What are the biggest challenges that you faced while raising capital?

The legal AI space has gotten noisy. There are a lot of companies pitching some version of “AI for law,” and investors have gotten appropriately skeptical of broad positioning.The challenge was making clear, quickly, that we’re not in that category. In addition to requiring deep specialization, patent work is categorically different, in domain complexity, in stakes, in the precision required at every step of the workflow.An inadequately managed patent portfolio doesn’t create a billing dispute. It creates a decade of competitive exposure. Once that reality landed, the traction data closed the argument: with over 40% of the Am Law 100 run, hundreds of corporate IP teams, and nearly 1,000% year-over-year growth.

What factors about your business led your investors to write the check?

First, the logos: over 40% of the Am Law 100 run on Patlytics — Quinn Emanuel, Foley & Lardner, Susman Godfrey, Canon, Rivian, Xerox, Asahi Kasei, and TaylorMade.At our stage, that’s tremendous traction in the best way, and it proved the market was real.Second, the timing: the AI-driven explosion in patent filings and IP litigation is not a future trend — it’s happening now, and Patlytics is already the infrastructure layer for it.Third, the architecture: we’re the only platform built ground-up as a unified system. Breadth without precision is a feature, not a platform. A purpose-built, end-to-end IP system with this traction, this customer quality, and this compounding architecture has an entirely different ceiling.

What are the milestones you plan to achieve in the next six months?

Some of these milestones have already been in motion, this raise accelerates their scale.On product: we’re launching a Collaboration suite that gives law firms and corporate IP teams a shared workspace to draft, review, and iterate together in real time, replacing the email-and-tracked-changes loop that has defined how firms and clients operate for decades.It will be infused with AI Agents that complete end-to-end tasks autonomously across drafting, research, and portfolio triage, and a judgment engine that predicts a practitioner’s next decision, directing agents to execute once the attorney confirms.We’re also going deeper into life sciences, where customer demand has been particularly strong, from startups that file their first patents at Series A all the way to public companies managing complex portfolios.On expansion: our London office is open, extending our EMEA presence for the first time. And we’re growing coverage across APAC, where IP activity has been traditionally strong and rising.

What advice can you offer companies in New York that do not have a fresh injection of capital in the bank?

Win something you can prove. The fundraising environment rewards specificity – a specific ICP, a specific use case, a specific wedge into a specific market.

Where do you see the company going now over the near term?

The category is forming fast . We have the infrastructure, the traction, and the tailwind. We’re deepening our position as the integration layer for the IP ecosystem, partnering exclusively with category leaders in e-discovery, file systems, licensing platforms, and litigation tools, because the attorneys and IP professionals we serve live inside those systems and want a seamless experience.Near term: international expansion, deeper life sciences penetration, enterprise go-to-market, and cementing our position as the default platform for IP work that actually matters.

What’s your favorite spring destination in and around the city?

I like to keep things simple. Playing basketball at the local courts, enjoying the restaurants and overall change of season is a blessing here in NYC.
