WISQ Opposition Dismissed with Prejudice - TTAB Decision TTAB91299021
Summary
The USPTO Trademark Trial and Appeal Board (TTAB) dismissed Opposition No. 91299021 with prejudice on April 10, 2026. Plaintiff Wilhelm Sihn Jr. GmbH & Co. KG brought the opposition against Defendant Wisq Inc. concerning the trademark WISQ. The opposition, originally filed May 15, 2025, was decided in favor of the applicant Wisq Inc.
What changed
The TTAB issued a final decision dismissing Opposition No. TTAB91299021 with prejudice, meaning the plaintiff cannot refile on the same grounds. The opposition challenging Wisq Inc.'s WISQ trademark registration was unsuccessful after proceedings before the Board.
For trademark applicants and IP practitioners, this decision underscores that opposition proceedings before TTAB can result in final, binding dismissals with prejudice. Companies seeking trademark registration should be prepared to defend against oppositions, while potential opponents should carefully assess the merits before filing to avoid adverse decisions that preclude future challenges to the same application.
What to do next
- Monitor TTAB decisions for precedent
- Review trademark opposition filing strategies
- Consult trademark counsel on opposition risks
