Revocation Grounds

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:

1. 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.
2. 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.
3. 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.
4. Misleading or False Information: If false or misleading information was provided during the trademark registration process, the registration may be revoked.
5. 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.
