To amend title 35, United States Code, to allow the Director of the United States Patent and Trademark Office to accept late filings in certain cases of unintentional delay.

Authorizes the Director of the United States Patent and Trademark Office (USPTO) to accept any application or other filing made by an applicant for, or owner of, a patent or trademark after the applicable deadline, as the Director considers appropriate, if the applicant or owner files a petition within 30 days after such deadline showing that the delay was unintentional. Deems such a petition denied if the Director has not made a decision within 60 days. Provides that the Director's decision is not subject to judicial review.

Deems that the 30-day period to file a petition after the deadline begins on the date of enactment of this Act for trademark applicants or owners.
