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.
Patent Co-operation Treaty (PCT)
The PCT, administered by the International Bureau (IB) of the World Intellectual Property Organization (WIPO) based in Geneva, Switzerland, is an international treaty to facilitate the applicant in seeking patent protection for his invention in several countries simultaneously by filing an international application with a single office, in one language and a single set of forms and fees. It may be initiated by a resident or national of a PCT contracting country wanting to seek protection in other PCT Contracting States. To apply, an applicant would file an international application with the patent office in his home country or the IB. The filing of a PCT request constitutes the automatic designation of all Contracting States that are bound by the PCT on the international filing date.
You can access the list of PCT contracting countries, PCT Applicant’s Guide and all the relevant forms here.
The PCT International Application Process
An applicant, who is a resident or national of Singapore, may file an international application under the PCT directly with the Registry of Patents in Singapore. We accept international applications in a type-written format or a printed-cum-digital format by using the PCT-SAFE software provided by WIPO. PCT-SAFE also provides a feature for the preparation of documents for electronic filing of PCT applications.
Please note that the Registry of Patents in Singapore is not ready to accept PCT applications filed electronically.
