Your Patent Questions, Answered
What can be protected as a Registered Design?
You can register the aesthetic (visual) features of a product—its shape, configuration, pattern, or ornament. The design must be “new” (not seen in public before) and applied to an article by an industrial process. Features that are purely functional cannot be registered.
How long does patent protection last in Singapore?
A standard patent, once granted, provides protection for up to 20 years from the date of filing, provided the annual renewal fees are paid.
Can I file an international patent from Singapore?
Yes. Singapore is a member of the Patent Cooperation Treaty (PCT). You can file a single international PCT application from Singapore, which acts as a placeholder, allowing you to seek protection in over 150 member countries later. We can manage this entire process for you.
