The Leahy-Smith America Invents Act (America Invents Act) includes provisions for prioritized examination of patent applications. Those provisions have been implemented by the United States Patent and Trademark Office (USPTO) in previous rulemakings. The America Invents Act provides that the USPTO may not accept more than 10,000 requests for prioritization in any fiscal year (October 1 to September 30) until regulations setting another limit are prescribed. In 2019 and 2021, the USPTO published interim rules that expanded the limit on the number of requests to 12,000 and 15,000, respectively. The current interim rule further expands the availability of prioritized examination by increasing the limit on the number of prioritized examination requests that may be accepted in a fiscal year to 20,000.
