{"jsonrpc":"2.0","id":1,"method":"tools/list"}ipc_lookup — Look up one International Patent Classification (IPC) symbol via WIPO IPCPUB — its English/French title, structural breakdown (section/class/subclass/group/subgroup) and whether it is a currently valid classification. Give "symbol" as a subclass ("A01N") or a full group/subgroup ("A61K 31/00"). IPC only — the related-but-different CPC scheme (EPO/USPTO) is not covered here.ipc_children — List the IPC symbols directly classified under one IPC symbol — the main groups under a subclass, or the subgroups under a group — with each child's title. Give "symbol" as a subclass ("A01N") or a group ("A61K 31/00").ipc_search — Find IPC symbols whose title text matches a keyword, e.g. "vaccine" or "solar cell". Returns matching symbols with their canonical ids — call ipc_lookup on a hit for its full title and validity.ipc_versions — List International Patent Classification (IPC) edition dates WIPO currently publishes, with the current (in-force) and latest (published, may be future-dated) editions named.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
