Bring Your International Application Into Singapore

30 months from the earliest priority date of your PCT application — this is the standard PCT deadline, and Singapore offers only very limited late-entry options.

Non-residents generally need a registered Singapore patent agent or address for service to prosecute the application, which Brealant provides.

Sometimes — claims that were acceptable internationally can require adaptation to meet Singapore examination practice, which we assess on entry, particularly for the local examination route.

You'll need to choose a grant route — local search and examination, or supplementary examination if you hold a corresponding foreign grant — generally within 36 months of the Singapore filing date.

Restoration options are very limited and not guaranteed, so it's important to instruct Brealant well before the 30-month deadline.

You can still choose between the self-assessment route, relying on a corresponding grant such as from the EPO or a PCT positive opinion, or requesting full local examination.

You'll need the PCT application number, a Singapore address for service, and payment of the national phase entry fee, plus a translation if the PCT application wasn't filed in English.

Generally no — relying on a corresponding foreign grant is usually less costly than requesting full local examination, which is one reason applicants often prefer it where available.

Yes, claims can generally be amended during Singapore prosecution, though amendments must still be supported by the application as originally filed.

A negative report doesn't automatically bar grant in Singapore, but it may steer you toward full local examination rather than the supplementary route, which Brealant can advise on.
