National Security Clearance 

A patent application may contain information which is prejudicial to national defence or public safety. In the interest of national safety, IPOS will need to assess the information contained in the application before deciding if such information could be made publicly available. 

If you are an applicant, inventor or agent residing in Singapore1, you are required to obtain a written authorisation from IPOS before applying a patent application overseas2

1: “Residing in Singapore” includes foreigners with valid pass lawfully issued to them e.g. Singapore permanent residents and work pass holders.
2:  A national security clearance is required if the application is first-filed overseas (ie: no declared priority date and is not a divisional application)

How to make a National Security Clearance Request?

You can apply for a National Security Clearance request via IP2SG , with a brief summary of the invention and drawings (if any). 

Upon receipt of your application, IPOS will respond within 3-5 working days. If your application requires urgent attention, you are encouraged to call us directly at (65) 6339 8616, quoting the E-file Reference Number of your application.
