Fearn is the AI-native patent prosecution firm built for startups. It pairs former Big Law patent attorneys with proprietary, hallucination-resistant AI models built in-house by PhD computer scientists to take an invention from disclosure to a filing-ready provisional or non-provisional patent draft in minutes rather than the 50+ hours typical of traditional firms, at flat-rate pricing with automated labeled-figure generation and a money-back guarantee tied to claim allowance. Fearn self-hosts its entire AI infrastructure and uses no third-party model APIs, keeping invention disclosures confidential and compliant with SOC 2, ISO 27001, ISO 27701, and GDPR. Founded in 2025 and headquartered in San Francisco; backed by Kindred Ventures and a16z speedrun. Fearn is a legal-services company and does not currently publish a public developer API.
