PatentAgentBench - Codex - Patent Drafting: leaderboard
PatentAgentBench Patent Drafting evaluates patent evidence search, comparison, drafting, responses and translation under Codex CLI 0.151.0. Its primary Weighted Rubric Score (%) 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: Weighted Rubric Score (%). Source: arxiv.org. Saturation forecast: Rough model projection: around 2026. 6 models tracked.
