Patent77

Patent77 supports early-stage patentability and novelty assessment through automated search planning, live patent record retrieval, and element-by-element comparison of an invention against prior art. The same engine is available through a web interface and programmatically. The tool is limited to patentability searching and does not perform freedom-to-operate analysis.

Key features and functions include:

Plain-Language Invention Input
Searches start from a paragraph or two describing what the invention is, what it does, and what is believed to be different. No query syntax or classification codes are required.

Automated Search Planning
The description is broken into the elements an examiner would compare, and alternative terms used in patent language are identified for each. Queries are written from these elements and terms.

Iterative Patent Search
Queries run against a live corpus of patent publications and repeat until the results stabilize. Every query run is displayed alongside the results.

Scored and Cited References
The closest documents are ranked by relevance, with an overall risk assessment. Each reference includes its publication number, a summary of what overlaps with the invention, and a link to the source document.

Element-by-Element Patentability Report
The report compares each element of the invention against the closest documents in a chart. Elements disclosed by a reference are marked, elements with no matching disclosure are left open, and any row or cell can be selected to see the reasoning behind the finding.

PDF Patentability Reports
Full reports include an overall verdict, an examiner-style novelty and obviousness analysis, and every reference mapped against the invention’s claims. Reports are exported as PDFs for review with patent counsel.

Invention Monitoring
Saved inventions are searched again each month against newly published art. New publications that come close to the invention appear in an in-app feed and by email.

Patent Lookup
Individual patent documents can be retrieved directly by publication number. Lookups return bibliographic data, the abstract, and claims, with a link to the source.

API and MCP Server Access
Search, document retrieval, and full patentability reports are available through a JSON API and a hosted MCP server, both authenticated with a single key. Patent-drafting agents, research assistants, and internal IP tools can call these as endpoints or MCP tools. Developer features include idempotent requests, structured error codes, signed webhook callbacks for long-running jobs, and a request log for reviewing what an agent ran.
