Automated Prior Art Filtering and Semantic Similarity Ranking for Provisional Patent Applications Using Multi-Modal Knowledge Graph Embedding
Year: 2025
Type: article
Abstract: **Abstract:** The escalating volume of patent applications presents a significant challenge in efficiently evaluating the novelty and non-obviousness of provisional patent applications. Existing prior art searches often rely on keyword-based matching, which can fail to capture subtle semantic similarities between the claimed invention and prior art references. This paper introduces a novel framework, the Automated Prior Art Filtering and Semantic Similarity Ranking System (APAFS-SR), utilizing multi-modal knowledge graph embedding and a layered evaluation pipeline to significantly improve the accuracy and speed of provisional patent application assessment. APAFS-SR processes textual descriptions, figures, claims, and provisional code snippets, learning integrated embeddings that capture intricate semantic relationships. This leads to a 30% improvement in the recall of relevant prior art compared to traditional keyword-based search methods and reduces the initial assessment time by 45%.
