Patlytics Raises $40M to Expand AI Patent Platform

Patlytics, a New York-based patent workflow platform, raised $40 million in a Series B round on April 8, 2026, led by SignalFire, to expand its AI-powered patent lifecycle software into new markets and industries.

The rise signals growing investor confidence in AI tools built for specialized legal workflows. Patent work has long relied on disconnected software and manual handoffs, driving up costs and slowing turnaround times for IP attorneys.

The Funding Round

The Series B round included participation from N47, Myriad Venture Partners, Relativity, Alumni Ventures, Antiportfolio Ventures, and BAM Corner Point. The new capital brings Patlytics' total funding to approximately $65 million, following a $14 million Series A led by N47 in 2025.

Relativity, an e-discovery company, invested through its investment arm Rel Labs. Patlytics CEO Paul Lee said the relationship grew through connections in the legal tech space and will include product-level integration between the two platforms.

"Andrew heard of us through just being in the legal tech space and thought it'd be a really cool ecosystem play for what we do," Lee said. "[The investment] also came [with] deep integrations with Relativity."
