Revocation grounds in trademark law refer to the circumstances under which a registered trademark may be revoked or canceled by a court or administrative body. The grounds for revocation vary depending on the jurisdiction, but may include the following:
- Non-use: If a trademark has not been used for a certain period of time, it may be subject to revocation. The length of time required for non-use to trigger revocation varies depending on the jurisdiction, but is typically between three and five years.
- Invalidity: A trademark registration may be invalidated if it was granted in error, such as if the trademark is identical or confusingly similar to an earlier trademark, or if it lacks distinctiveness.
- Deceptiveness or Descriptiveness: If a trademark becomes deceptive or descriptive of the goods or services for which it is registered, it may be subject to revocation.
- Misleading or False Information: If false or misleading information was provided during the trademark registration process, the registration may be revoked.
- Bad Faith: If a trademark was registered in bad faith, such as to prevent others from using a similar trademark, it may be subject to revocation.
