## Description

Patent Bear is a patent research platform that connects with AI assistants, including Claude, ChatGPT, Codex, and Gemini. It gives users and their agents access to structured patent records, with source material such as claims, specifications, figures, prosecution histories, citations, and court decisions linked to precise citations. Its search tools cover US and European patents, with advanced filters for assignees, inventors, classifications, dates, and citations, as well as patent status, term, and litigation checks. Researchers can examine cases page by page, search DNA, RNA, and protein sequences by homology, and find chemical structures by substructure or similarity. Patent Bear also supports prior-art, claim-charting, disclosure, clearance, and invention analyses, alongside drafting tools for items such as Information Disclosure Statements and claim-definition sections. A private library organizes saved patents, matters, notes, highlights, analyses, and alerts. The service offers free patent searching and a free tier of 20 connector requests per month, helping users move from AI-generated answers to cited passages and underlying patent records for verification.
