Since 1995, the Singapore patent system has moved away from a re-registration system to the present examination system. However, applicants could still rely on allowed foreign applications for grant through a two-stage process. An applicant would first furnish details (country of filing, filing dates and application numbers) of all corresponding applications within 16 months of the priority date. Subsequently, the applicant would furnish prescribed information in the form of granted patents or documents setting out the final results of the search and examination of any one of the corresponding applications before 28 months of the priority date.
