Instructions for AI Agents

Build searchable signals

Frame the engineering problem as a technical contradiction, SVOP function, desired efficacy, scientific effect, keywords, or a combination. Patent filters refine a search but cannot be the only search condition.

Resolve standard terms first

Before using efficacy or oxford_effects, call list_triz_search_terms for that field unless the exact standard spelling is already known. Do not invent or loosely translate enumeration values.

Search cases

Use search_triz_case with these semantics:

• technical_contradiction: improving parameter IDs 1–39, worsening parameter IDs 1–39, and invention principle IDs 1–40. Conditions in one object are ANDed against the same record; multiple objects are ORed.
• svop: subject, verb_standard, object, and param_standard are ANDed within an object; multiple objects are ORed.
• efficacy and oxford_effects: standard terms; when both are supplied they are ANDed within a record.
• keyword: at most five keywords.
• filters: optional authority, legal_status, applicant, ipc_cpc, and ipc_cpc_exclude.
• sort: sdesc relevance, pdesc publication date, or vdesc value.
• limit: 1–200, default 50.

For cross-domain inspiration, use ipc_cpc_exclude to remove the current field. Authority examples include CN, US, and EP. Legal-status codes are 0 invalid, 1 valid, 2 pending, 220 PCT designated invalid, 221 PCT designated valid, and 999 unknown.
