You may encounter a dispute in the course of protecting your patent. This could be in the form of revocation of your granted patent.

If you are facing the prospect of (or are currently involved in) a dispute and do not have legal representation, we strongly recommend that you seek legal assistance.

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.
