FindIP vs Patent77

FindIP provides patent search through a browser playground and a REST API for use in other services. It searches published patents from the US, China, Japan, Korea, and Europe; full-text coverage begins in 2001, except China, where it begins in 2010. Semantic search matches text by meaning, while drawing search finds visually similar patent illustrations. Sequence search covers similar DNA, RNA, or protein sequences. Image and sequence results can be reranked by topic. Queries may be written in English, Korean, Japanese, Chinese, or German across all five jurisdictions. FindIP says each result is a publication in its database that can be checked by publication number. Its MCP connection supports Claude Desktop and Web and ChatGPT during beta. The Free plan costs nothing and includes 30 search credits and all APIs. Basic costs $45 a month, billed excluding tax, and includes 300 monthly credits. Text searches use one credit; image search, sequence search, and trend analysis use two. The listed rate limit is 60 requests per minute on Free, Basic, and Pro; Enterprise has a custom limit.

Patent77 searches public patent records for prior art from a plain-English description of an invention, then returns cited references and a knockout-risk read. Its engine breaks the description into claim-style elements, expands synonyms, iterates searches, examines candidate documents and scores relevant references. Searches query the live Google Patents record, including US and major international patent collections. Paid patentability reports add an element-by-reference map, a novelty and obviousness narrative, limitations and PDF export. Lookups by publication number are never billed. Patent77 offers a web app, JSON API and hosted MCP server with tools for prior-art search, patent lookup and patentability assessment. Anonymous API requests need no account, but are limited to 4 requests per minute, 20 per day and three references per search. The Free plan is free and includes 3 AI searches per month and the top 5 references. Pro costs $49 a month; Scale costs $199 a month. Patent77 says descriptions are account-scoped and not used to train models, shown to others or sold, while descriptions are sent to an AI provider for query planning and reference reading. It does not cover non-patent literature, unpublished applications in the 18-month publication window or collections outside its corpus, and it is not legal advice.
