Fearn has raised $5.5 million in a Seed round to accelerate its AI-native patent platform. The San Francisco, California company announced the round led by Kindred Ventures.
Joining the round were a16z speedrun, Designer Fund and Essence VC. Founded in 2025 and led by CEO Han Kim, Fearn is building a patent platform designed for a first-to-file world, where being early to submit can matter as much as the invention itself. The company pairs purpose-built, hallucination-resistant models with automated labeled-figure generation, taking an invention from initial disclosure to a filing-ready draft in minutes at a flat rate of $2,000 per patent.
The pitch centers on speed and cost. Fearn says it can cut patent drafting from more than 50 hours to roughly 20 minutes while reducing costs by up to 96 percent. If those figures hold up in practice, the implications are significant, because patent drafting has long been expensive enough to put strong protection out of reach for many smaller inventors. The company frames its mission as ending what it calls the two-tier patent system, where well-funded organizations can file faster and more thoroughly than everyone else.
The emphasis on hallucination-resistant models matters in this context. Patent filings demand precision, and errors can be costly, so an AI tool in this space has to be built to avoid the kinds of mistakes that general-purpose models sometimes make. Fearn’s approach suggests it has designed its system with the specific demands of legal and technical accuracy in mind.
The company plans to use the funds to expand its patent models and product capabilities, including the automated labeled-figure generation that helps turn an idea into a complete draft. By targeting solo researchers and enterprise R&D teams alike, Fearn is betting that faster, cheaper patent drafting will appeal across the spectrum of inventors.
