In Ukraine, registered trademarks can only be invalidated through a court proceeding. Some key points about trademark cancellation procedures include:
- Interested parties can file lawsuits seeking cancellation on grounds of non-use or that the trademark fails to meet registration requirements.
- Court proceedings typically take 5-7 months and may involve expert analysis to examine distinctiveness or likelihood of confusion issues.
- Trademarks can be invalidated fully or partially and the grounds for invalidation include lack of distinctiveness, functionality, misleading nature, violation of earlier rights, and non-use.
- Several case examples are provided where Ukrainian courts decided on trademark validity issues based on the specific facts and arguments made by plaintiffs and defendants.
