We study this problem through Vibe Patenting, an end-to-end patent-drafting testbed for AI-agent evaluation. A separately-invoked LLM judge evaluates generated patent drafts and provides structured feedback for iterative revision. Across multiple inventions and drafting-agent configurations, judge-guided revision consistently improves judge-assessed quality, while unguided revision tends to saturate. Notably, iterative judge feedback enables a low-reasoning agent to approach the performance of a substantially more expensive high-reasoning agent. Stronger models and increased reasoning generally improve judge-assessed drafting quality, while domain-specific agentic workflows provide further gains. We validate the judge against independent evaluation by a professional patent attorney and find meaningful but strongly metric-dependent agreement and systematic calibration differences. These results highlight both the utility and limitations of LLM judges as evaluators and optimization signals for complex professional workflows.", "url": "https://wpnews.pro/news/vibe-patenting-evaluating-llm-judges-for-professional-patent-drafting-agents", "canonical_source": "https://arxiv.org/abs/2609.13422", "published_at": "2026-09-15 04:00:00+00:00", "updated_at": "2026-09-15 04:35:19.345390+00:00", "lang": "en", "topics": ["large-language-models", "ai-agents", "ai-research", "ai-tools"], "entities": ["Vibe Patenting", "arXiv", "LLM judges"], "alternates": {"html": "https://wpnews.pro/news/vibe-patenting-evaluating-llm-judges-for-professional-patent-drafting-agents", "markdown": "https://wpnews.pro/news/vibe-patenting-evaluating-llm-judges-for-professional-patent-drafting-agents.md", "text": "https://wpnews.pro/news/vibe-patenting-evaluating-llm-judges-for-professional-patent-drafting-agents.txt", "jsonld": "https://wpnews.pro/news/vibe-patenting-evaluating-llm-judges-for-professional-patent-drafting-agents.jsonld"}}
