# Japan Intellectual Property High Court

Use the public `JapanIpHighCourtClient` or the MCP tools
`search_japan_ip_high_court_cases` and `get_japan_ip_high_court_case` to
inspect the court's official weekly patent and utility-model case workbook.

Search defaults to the pending sheet. Useful identifiers are Japanese court
case numbers such as `令和7年（行ケ）第10011号`, Japanese patent numbers such as
`特許5892637`, and application numbers such as `特願2018-545340`.

The workbook covers suits seeking cancellation of JPO patent and utility-model
decisions. It does not publish parties, pleadings, or docket entries and is not
a general infringement docket. Do not describe it as party-search coverage.
