If your basic mark is cancelled within five years, your Singapore trade mark designation is cancelled through a Madrid Protocol central attack — but transformation can save it.

If the basic mark on which your international registration is based is cancelled (or otherwise ceases to have effect) within the five-year dependency period, the International Bureau (WIPO) will cancel the international registration — including your Singapore designation — to the same extent that the basic mark was cancelled or restricted.

In practice, this means:

• If the basic mark is cancelled in whole, your Singapore designation is cancelled in whole.
• If the basic mark is restricted to fewer goods/services, your Singapore designation is restricted to match.

WIPO notifies the holder and the designated Contracting Parties (including IPOS). Once cancelled, the international registration no longer gives you protection in Singapore through the Madrid route — but you may be able to salvage it by transformation into a Singapore national application (see the related FAQ on transformation).

The dependency clock runs from the date of the international registration, not from any later subsequent designation. A Singapore designation added after the original filing is still exposed to the same five-year window.
