You may encounter a dispute in the course of protecting your intellectual property (IP). This could be in the form of an opposition to your trade mark application, or a revocation of your granted patent, or an infringement of your registered design.

The diagram below shows the possible routes that an IP dispute may take.

Dispute Resolution Routes

Trade Mark Opposition

In Singapore, it is possible to stop the registration of a trade mark. This is known as trade mark opposition. Some grounds of opposition could be that the trade mark sought to be registered is descriptive of the goods or services for which registration is sought, or that it is confusingly similar to an earlier trade mark.

The grounds for opposition, procedure and timelines are prescribed by law under the Trade Marks Act and Rules.

The flowchart below outlines the procedures and timelines for opposing a trade mark application. You may access an enlarged copy of the flowchart here.

Trade Mark Invalidation or Revocation

In Singapore, it is possible to invalidate or revoke a registered trade mark.

Invalidation and revocation are two very different processes.

Invalidation is intended to remove from the register marks which should never have been registered in the first place, because such marks fail to satisfy the registration criteria. For example, the registered trade mark is descriptive of the goods or services for which registration is sought, or is confusingly similar to an earlier trade mark.

Revocation, on the other hand, is intended to remove marks whose initial registration was valid, but which should not be allowed to remain on the register. The reason could be because of the proprietor’s failure to use the registered trade mark or because it has become the common name in the trade for the product or service for which it is registered, or because it has become misleading. Revocation allows such marks to be released to the public for use.

The grounds for invalidation and revocation, procedure and timelines are prescribed by law under the Trade Marks Act and Rules.

Patent Revocation

In Singapore, it is possible to challenge the validity of a granted patent through an application for patent revocation. If the application is successful, the patent will be wholly or partially revoked from the date of grant.

The grounds for revocation, procedure and timelines are prescribed by law under the Patents Act and Rules.

The flowchart below outlines the procedures and timelines for patent revocation. You may access an enlarged copy of the flowchart here.

You are encouraged to consider mediation (for all proceedings) and expert determination (for patent proceedings) as time- and cost-effective alternatives to adjudication for resolving your dispute.
