Patent Bear now works inside Claude, ChatGPT, and Gemini.

Patent Bear is an AI-powered patent research workspace built for patent attorneys, inventors, and IP teams. It combines fast patent search, clean patent reading, prosecution history review, annotations, claim charts, and cited AI assistance in one place. Patent Bear is powered by a dedicated patent corpus built from public patent records and related technical sources. That retrieval layer supports Ursa, our AI patent assistant, and Patent Bear Labs for workflows like prior art searching, invention review, disclosure analysis, and clearance screening. Our goal is simple: make patent research faster, more organized, and easier to verify, with citations back to the underlying patent record.
