Heterogeneous Dependency Graph-Guided Attentionfor Patent Representation Learning

Longbing Cao, Qiongkai Xu, Yongmin Yoo, Zhangkai Wu

A heterogeneous graph encoder that preserves patent claim dependencies outperforms text-only baselines by treating intra-document topology as the primary inductive bias.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

PHAGE outperforms all baselines on classification, retrieval, and clustering, showing that intra-document claim topology is a stronger inductive bias than inter-document structure and that this bias persists in the encoder weights after training.

C2weakest assumption

The deterministic graph construction pipeline can reliably separate near-deterministic legal citations from noisier rule-based technical relations while preserving type distinctions as heterogeneous edges.

C3one line summary

PHAGE encodes patent claim hierarchies as heterogeneous graphs inside Transformers and outperforms baselines on classification, retrieval, and clustering by treating intra-patent topology as a stronger signal than inter-patent links.
