PatentAgentBench - Claude Code - Invalidity Search: leaderboard
PatentAgentBench Invalidity Search evaluates patent evidence search, comparison, drafting, responses and translation under Claude Code 2.1.251. Its primary Macro Recall@All (%) uses the full assigned case denominator, including final failures after up to three execution-failure retries. Harnesses and unreported model effort remain distinct source configurations. The suite has 510 patent cases; its public banks contain 1,311 records because translation's 80 cases contain 881 segment items.
Metric: Macro Recall@All (%). Source: arxiv.org. Saturation forecast: Rough model projection: around 2026. 7 models tracked.
