When assigning a Singaporean patent filing, care should be taken to ensure that the assignment not only complies with the provisions of the Singapore Patents Act but also that the assignment is recorded in a timely manner at the Registry.

Singapore Courts tend to adopt a strict approach to the exclusion of added subject matter when amending a patent or patent application. Hence, does a disclaimer, introduced into a patent claim in order to restore novelty over the prior art by excluding from its scope one or more particular examples in the prior art, constitute unallowable added subject matter under Singapore law if such a disclaimer has no basis in the application as originally filed?

Until now a national phase entry application in Singapore under PCT Chapter I had to be filed within 20 months from the priority date (or international filing date if priority is not claimed).
