Benchmarking Patent Embeddings: A Multi-Task Evaluation of 22 Models Across Retrieval, Classification, and Clustering

Researchers benchmarked 22 embedding models on patent data, finding that optimal fine-tuning strategies vary by task and that single-landscape fine-tuning degrades cross-domain performance. The study reveals significant gaps between in-domain and out-of-domain retrieval that cannot be closed with hybrid approaches, challenging assumptions about universal embedding solutions.

AI Patents in the United States and China: Measurement, Organization, and Knowledge Flows

Researchers developed an advanced AI classifier achieving 97% precision in identifying AI patents, revealing that both the U.S. and China are rapidly expanding AI innovation but through fundamentally different institutional structures. While China recently surpassed the U.S. in annual patent volume, American AI patenting remains concentrated among large private firms, whereas Chinese innovation is more geographically dispersed across universities and state-owned enterprises.

TRIZ-RAGNER: A Retrieval-Augmented Large Language Model for TRIZ-Aware Named Entity Recognition in Patent-Based Contradiction Mining

Researchers developed TRIZ-RAGNER, a retrieval-augmented large language model framework that improves patent analysis and systematic innovation by extracting technical contradictions from patent documents. The system achieved 84.2% F1-score accuracy, outperforming existing methods by 7.3 percentage points through better integration of domain-specific knowledge.
