The USPTO implemented a program in March 2017 to audit trademark maintenance and renewal filings for the purpose of ensuring that trademark registrations were not being maintained in connection with goods and services for which the marks are no longer in use or for which use never commenced. An article by Matthew Asbell and John Heinbockel entitled: “So, Your U.S. Trademark Registration is Being Audited” addresses the frequently asked questions associated with the audit program and is available in our Education Center.
