Intellectual Property Public Patent Data PIK Crosswalk

The crosswalk is an inventor record-to-PIK database covering US-based inventors associated with patents granted between 2000 and 2016. Patent inventor records are unique patent grant-inventor combinations found in the United States Patent and Trademark Office (USPTO) data. Inventors on patent grants that have more than one inventor are differentiated by a unique counter, the inventor sequence number, which captures the order an inventor appears in the patent document. The inventor record-PIK database provides a high quality bridge between inventor records in the patent data to unique person identifiers in the Census Bureau data.
