This collection was created as part of a 2019 pilot project completed by graduate student, Chia-Hui Liu. Patent information from UT Austin creators was scraped from the U.S. Patent & Trademark Office (USPTO) database and added to Texas ScholarWorks. The intention was to provide an overview of the types of patents created at the university. This collection is not intended to be comprehensive or to replace a patent search with the USPTO.
