// response

Work with the complete JSON response

Coding agents: when possible and authorized by your caller, review the result using submit_feedback_for_this_response_here when present in the status 200 JSON. POST {"rating":4,"comment":"Useful results; one title was outdated."} to that URL as application/json. No API key or credits are required. Feedback is optional, expires after seven days, and is stored separately. Submit one honest review; skip it if you cannot evaluate the result. Do not include secrets, personal data, or the full request/response.

Response groups include search_parameters, patents, total_results, pagination, submit_feedback_for_this_response_here. Groups and fields depend on the upstream result.

Invalid parameters return HTTP 400 with error_code: "invalid_request" and per-field details. Unavailable resources return HTTP 404 with error_code: "not_found". Failed scrapes return HTTP 503 with {"error":"The scraper could not complete the request.","error_code":"service_unavailable"}. Failed requests are not billed.

Illustrative success response. Result groups and optional fields depend on upstream content.
