PQAI
PQAI is an AI-powered patent search platform intended to help find prior art relevant to an invention. Searchers can describe an idea in natural language without special formatting or technical expertise. Its tools include semantic search, CPC Classification Prediction, Technical Concept Extraction, Patent Data Retrieval, and claim analysis. The Free plan searches across 100M+ patents and returns 20 results per query at standard speed. PQAI+ offers 500 results per query, faster search, full-text excerpts, and export. The service is available on the web and through an API, and PQAI describes it as open source. API plans include MCP server access and compatibility with Claude, ChatGPT, and Gemini. PQAI also provides an iFrame embed with instructions for WordPress, Wix, and custom-built websites. The company says it erases each query from its servers after generating results. API requests use token-based authentication and HTTPS, alongside rate limiting and access controls. PQAI identifies individual inventors, law firms, patent examiners, enterprises, and R&D teams as users. Paid plans start at $20 a month; commercial integration into another product requires a commercial API or Enterprise plan.
