To amend title 35, United States Code, to conform certain filing provisions within the Patent and Trademark Office.

Allows the Director of the United States Patent and Trademark Office (USPTO) to accept an application for an extension of the term of a patent which claims a product, a method of using a product, or a method of manufacturing a product if: (1) such application is filed no more than 5 days late; and (2) the applicant files a petition showing that the delay in filing the application was unintentional. Deems such petition to be denied if no determination has been made on the petition within 30 days of filing. Establishes the fee for filing such a petition.

Applies this Act to any application for patent term extension which: (1) is pending on the date of enactment; (2) is the subject of a request for reconsideration of a denial of a patent term extension; or (3) has been denied a patent term extension in a case in which the period for seeking reconsideration of such denial has not yet expired.
