Patent protection is territorial in nature. To obtain patent protection overseas, you can
i) either file individual applications in the countries concerned;
ii) or go through the Patent Co-operation Treaty (PCT), which facilitates the filing of International Applications.
IMPORTANT NOTE: For national security purposes, any person residing in Singapore is required to obtain written authorisation from the Registrar of Patents before he files or causes to be filed outside Singapore an application for a patent for an invention. Please click here for more information.
