Following the move from a self-assessment system to a positive-grant system in 2014, a Singapore patent application can only proceed to grant if the relevant requirements are fulfilled, including patentability requirements. An applicant can still elect the examination route for his application to meet such requirements. Where a positive final result from a PCT, corresponding or related application is available, the applicant has the option of requesting supplementary examination with a view to a quick examination of the application in a relatively cost-effective manner.
