LLMs improve patent novelty assessment with fine-grained passage retrieval

Researchers have introduced FiNE-Patents, a new dataset and methodology for fine-grained patent novelty prediction. This approach moves beyond simple binary classification to a more granular task of identifying specific passages in prior art that disclose individual claim features. LLM-based workflows were developed and evaluated, demonstrating superior performance in passage retrieval and novel feature identification compared to embedding-based baselines. AI
