This Practice Note discusses the deadlines and requirements for maintaining federal trademark registrations with the US Patent and Trademark Office (USPTO). The Note covers proving continued use (Section 8 and Section 71 Declarations or Affidavits), renewing registrations (Section 9 Applications), and filing for incontestability (Section 15 Declarations or Affidavits), including special requirements for international registrations.
Since 2020, the USPTO has issued several notices concerning the extension of certain trademark-related timing deadlines and fee waivers under the Coronavirus Aid, Relief, and Economic Security Act (CARES Act).
