For decades, patent applications have followed the same outdated routine — drafted manually, one word at a time. While most legal sectors embraced automation, the patent process remained stuck in the past. Now, New York and Paris-based startup DeepIP is changing that with its cutting-edge AI patent assistant.
The startup just secured $15 million in Series A funding, with lead backing from AI-focused fund Resonance. Other notable investors include Headline (backers of Mistral AI), Serena Capital (Dataiku), and Balderton Capital. This funding will power DeepIP’s product development and market expansion across the U.S. and Europe.
The way patents are filed hasn’t evolved much since the ’90s. Costs run between $20,000 to $100,000, the approval process stretches 2 to 4 years, and legal teams face growing pressure to work faster. Patent filings globally now exceed 3.5 million annually, rising 4.4% each year. Meanwhile, more than a million applications are still pending at the USPTO.
With timelines halved and complexity rising, IP attorneys face an uphill battle. That’s where DeepIP comes in. Their AI solution cuts drafting time in half and boosts accuracy, clarity, and legal defensibility.
Founded in 2024 by François-Xavier Leduc and Edouard d’Archimbaud—previously the minds behind Kili Technology—the team brings deep expertise in AI and legal tech. They’ve built solutions for global organizations like Airbus, SAP, and IBM. At DeepIP, they’ve merged proprietary AI with third-party models, using exclusive data access to dramatically reduce hallucinations—one of AI’s biggest challenges in legal applications.
Unlike standalone AI tools that disrupt workflows, DeepIP integrates directly into Microsoft Word—where most patent attorneys already work. Their assistant helps with drafting, editing, summarizing, and even highlighting novel aspects of inventions. It also simplifies complex jargon, flags missing elements, and suggests stronger claim structures.
What makes it stand out is the ability to analyze historical patent applications, learning the unique writing style of specific firms, attorneys, and clients. That means DeepIP doesn’t just write fast—it writes like you.
“We’re not replacing professionals—we’re making them faster, sharper, and more strategic,” said CEO François-Xavier Leduc. “We built this through constant feedback with the top 50 U.S. IP law firms, and saw product-market fit almost instantly.”
And it’s already proven. DeepIP’s platform has been used to draft over 8,500 patent applications, helping leading firms like Jacobacci & Partners and Schwegman, Lundberg & Woessner work more efficiently. The tool ensures GDPR compliance, follows Zero Data Retention policies, and meets high security standards with SOC 2 Type II and ISO 27001 certifications.
In just seven months, DeepIP hit seven-figure annual recurring revenue (ARR)—a pace rarely seen in legal tech. That kind of momentum caught the attention of investors.
“DeepIP is the fastest company I’ve ever seen to reach $1 million ARR,” said Maxime Le Dantec from Resonance. “It’s clear proof of the massive productivity boost it gives IP lawyers.”
Jonathan Userovici of Headline echoed that sentiment: “This isn’t about AI replacing jobs. It’s about empowering professionals to do more. IP lawyers see so much value that some have said they’d buy it personally if their firms didn’t.”
DeepIP’s rise also comes at a pivotal time. In July 2024, the USPTO issued new guidance for evaluating AI-related inventions, further validating the need for smarter patent filing tools. As innovation speeds up, the tools that support it must keep pace—and DeepIP is aiming to lead that shift.
