For International (PCT)

PCT Applicant’s Guide – International Phase

The PCT Applicant’s Guide – International Phase contains general information on the Patent Cooperation Treaty (PCT) for those interested in filing international patent applications. The guide, consisting of 11 chapters provide useful information about the benefits of PCT to applicants including filing, search and examination procedures.

The IP Office of Singapore (IPOS) is a competent ISA and IPEA recognized by the US, Japan, Mexico, Indonesia and Vietnam.  Both manual filing or electronic filing (via ePCT portal) are accepted by IPOS, although the latter is preferred.


Singapore as Receiving Office

IPOS accepts international (PCT) application in both English or Chinese, and is the only patent office apart from China to accept patent application in Chinese. The business friendly service enables the deferment of translation costs from Chinese into English until the national phase entry stage. 


Supplementary Search

A SIS can be conducted when an applicant wants a second opinion. The additional search has the potential to reduce the risk of new prior art being cited in the national phase by expanding both the linguistic and technical scope of documentation searched. With the increased market penetration of international brands into China, IPOS is primed as the only ISA under the PCT that is able to carry out a SIS in both English and Chinese. 




The ASPEC programme is intended to provide ease of sharing of search and examination results between the participating offices to allow applicants in participating countries to obtain corresponding patents faster and more efficiently. For Singapore, the average pendency rate to first office action after ASPEC request1 is 5.7 months.

While both manual filing or electronic filing are accepted by IPOS, the latter option is preferred. 

1Only ASPEC requests where an office action had been issued are included.
