Rules 57 - 60 and 72 - 76 of the Trade Marks Rules
1. A person may apply to revoke or invalidate a registered trade mark by filing an application for revocation or declaration of invalidity. The procedure is as follows:
File with us Form TM28 and a statement of grounds (together with payment of S$420 x number of classes for which the revocation or declaration of invalidity is sought).
Send to the proprietor a copy of the same Form TM28 and statement of grounds at the same time that they are filed with us.
2. Within 2 months after the date of receipt of the application for revocation or declaration of invalidity from the applicant, if the proprietor wishes to maintain the registration of the trade mark, he must file a counter-statement in Form HC6 that includes the grounds on which he relies as supporting his registration; and the facts alleged in the application which he admits, if any. The procedure is as follows:
File with us Form HC6 (together with payment of S$360 x number of classes for which the revocation or declaration of invalidity is sought). In the case of an application for revocation based on grounds of non-use, a statutory declaration setting out evidence of the use by the proprietor must also be filed.
Send to the applicant a copy of the same Form HC6 (and evidence of use, where applicable) at the same time that it is filed with us.
If these steps are not complied with, the application for revocation or declaration of invalidity shall be granted.
2a. The proprietor may request for an extension of time to file the counter-statement by filing Form HC3. The procedure is as follows:
Within 2 months after the date of receipt of the application for revocation or declaration of invalidity from the applicant, file with us Form HC3.
Send to the applicant, and each person likely to be affected by the extension, a copy of the same Form HC3 at the same time that it is filed with us.
3. The revocation or invalidation proceedings are suspended from the date that the counter-statement is filed. We will send a letter to encourage parties to engage each other to explore dispute resolution options.

Parties may request for an extension of time to file the Notification to Registrar form. The procedure is as follows:

Once parties let us know of their intention to mediate, we will generally suspend the IPOS proceedings for mediation to take its course. The parties may set aside 30, 60 or 90 days for mediation. This period may be extended upon further request and justification by parties.
Notwithstanding the specific incorporation of the mediation option to the procedure after the counter-statement is filed, parties may request for mediation at any time before we decide on the outcome of the case.
4a. Within 2 weeks after the end of the mediation, parties should inform us in writing of the outcome of the mediation. If there are any remaining issues in the dispute to be heard by IPOS, we will give further directions on the conduct of the case in writing or in a Case Management Conference.

Within the specified evidential deadline, file with us a statutory declaration in the Evidence by Respondent Form.
Send to the applicant a copy of the same statutory declaration at the same time that it is filed with us.
If these steps are not complied with, the proprietor is deemed to have admitted to the facts alleged by the applicant in his application for declaration of invalidity. We will direct parties to inform us in writing how they intend to proceed.

The parties shall file with us their written submissions and bundles of authorities at least 1 month before the date of hearing and shall at the same time exchange with one another their respective written submissions and bundles of authorities.
