operationId: prior_art_invalidator
summary: Global Prior-Art Patent Invalidator
description: 'Screens a patent''s claims against scholarly literature published before the priority date (arXiv, OpenAlex, Europe PMC, Crossref, HAL, J-STAGE; English, Chinese, Japanese, German; not patent databases). Give claims plus a priority date, or a patent number to read them from Google Patents. Claims are split into elements in code; every claim-chart quote is verified verbatim against the title or abstract. Returns a headline decision (anticipation likely / obviousness likely / insufficient evidence), a rule-based invalidation score, 102 and minimal 103 paths, and a draft IPR / reexamination brief with [PLACEHOLDERS] for a registered practitioner to review. Abstract-level evidence only; not legal advice.
Price: 1.00 USDC on Base (x402).'

description: Publication number such as US7629993B2. Claims, priority date and cited art are read from Google Patents when the claims or the date are omitted, and the date is cross-checked otherwise. Required unless both patentClaimsText and priorityDate are given.

priorityDate: '2017-06-01'
patentClaimsText: '1. A method of approximate nearest neighbor search comprising: hashing each data vector with a plurality of locality-sensitive hash functions to generate hash codes; storing the vectors in hash tables indexed by the hash codes; and, for a query vector, retrieving candidate vectors from the buckets matching the query''s hash codes and ranking the candidates by exact distance to the query vector.'
