Ambercite vs Patent77

Ambercite is a web and API platform for finding patents related to one or more starting patents. Ambercite Ai uses deep-learning and network algorithms to score and rank similar patents from a database described as containing over 106 million patents and 175 million citations. AmberScope maps and clusters similar or important patents that cite one another. The listed applications include prior-art searching, licensing, instant patent landscaping and portfolio benchmarking. Users can run it alongside existing patent-search databases or as a standalone tool. An API is available to patent offices and non-competing industry players. The maker identifies corporations, patent examination offices, IP firms, analysts and searchers as users. AmberScope is also aimed at R&D teams and business owners who are unfamiliar with Boolean parameters or technical class codes. A 21-day trial provides both products without a card or payment and allows 20 searches. Trial searches accept up to three patents, show up to 25 results, obscure five more randomly, and cannot be exported to Excel. Paid subscriptions are annual, with pricing based on organization details.

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 It does not cover non-patent literature, unpublished applications in the 18-month publication window or collections outside its corpus, and it is not legal advice.
