AI Analysis & Value Prop

This dataset contains amended claims, the original specification and claims, drawing descriptions, and written opinions from patent prosecution. It links individual amendment units to the original disclosure passages that may support them, with evidence chains, retrieval-ready chunks, passage locations, and an overall support judgment. The dataset supports amendment-basis review, legal document evidence retrieval, and the training and evaluation of retrieval-augmented generation systems for patent prosecution.
