Citations_search_oa_citations_balanced

Search Office Action Citations (v2) with all 16 available fields. Prior art cited against an application, Form 892, Form 1449, IDS references, 102 103 112 statutory basis, action type, paragraph number.

Use after Citations_search_oa_citations_minimal for detailed analysis of selected applications. All fields: patentApplicationNumber, groupArtUnitNumber, techCenter, referenceIdentifier, parsedReferenceIdentifier, actionTypeCategory, legalSectionCode, examinerCitedReferenceIndicator, applicantCitedExaminerReferenceIndicator, officeActionCitationReferenceIndicator, workGroup, paragraphNumber, createDateTime, createUserIdentifier, obsoleteDocumentIdentifier, id.

This tier is where the OA-only analytical fields live: legalSectionCode (102/103/112 statutory basis) and actionTypeCategory ('rejected') have no equivalent in the enriched lane, and paragraphNumber locates the citation within the office action.

⚠️ APPLICANT-CITED (1449/IDS) COVERAGE IS PARTIAL. This lane is documented upstream as transcribing Form 892 AND Form 1449, but on IDS-heavy files it returns close to what the examiner applied and little else, in every era. Measured against the patents' own References Cited pages (union of BOTH lanes): US 7,971,071 -> 5 of 91 US 9,496,922 -> 1 of 251 US 9,135,462 -> 0 of about 620 US 11,656,067 -> 3 of 15, prosecuted 2021-2023 INSIDE the documented window A reference's absence here is NO evidence that the applicant did not disclose it, and a count from this lane is not the applicant's full IDS. For a complete 1449 record, read the IDS documents through the PFW MCP.

CROSS-LANE JOIN KEY: every row carries referenceKey, the normalised reference identifier, and it is the ONLY correct key for unioning this lane with the enriched lane. On app 12849948 this lane's parsedReferenceIdentifier reads '20060075466' while the enriched citedDocumentIdentifier reads 'US 2006/0075466 A1'; joining those two raw fields finds zero overlap on every application, when the true answer there is four references in both lanes. referenceKey is digits only (a leading US, spaces, slashes, hyphens and the kind code stripped, series markers such as RE kept) and is carried on both lanes at every tier. It is null on a row whose identifier does not reduce to a document number.

OA Citations v2 documented window: office actions mailed 2017-10-01 to ~30 days prior to today (older records have been observed in practice). No office-action date field exists — do not add an officeActionDate clause (HTTP 400).

⚠️ publicationNumber IN criteria IS A DELIBERATE 400 HERE, AND THAT IS A FEATURE. The raw upstream API answers that field with HTTP 200 and numFound 0, which reads as "this patent was never cited" and is silently wrong. This server refuses the clause so the mistake is visible. Use the patent_number parameter for the subject patent, or parsedReferenceIdentifier to find where a patent was CITED.

IDENTIFIERS: application_number is the APPLICATION serial. This index has no patent-number field (publicationNumber returns HTTP 400), so patent_number is crosswalked here: pass a GRANTED patent number (7-8 digits; commas, spaces and a US prefix accepted) and it is resolved to its application serial with one USPTO ODP applications-search call, then queried as patentApplicationNumber. The response reports the mapping in patent_number_resolution {input, interpreted_as, resolved_application_number, source}. An 11-digit pre-grant publication number is refused here (use Citations_search_citations_balanced for those), an unresolvable number is a 400 naming the accepted forms, and a patent_number that disagrees with a supplied application_number is a 400 rather than a query that can only return zero.
