This dataset contains the first independent claim from US utility patents spanning 2005-2025. Patent claims define the legal scope of an invention, and the first claim is typically the broadest and most important claim in a patent. The dataset is organized by year, with each year stored as a separate parquet file. The data fields include patent ID and claim text. The dataset was created by filtering, cleaning, and length filtering from PatentsView bulk data.
