    Patent registration in Singapore through PCT system

    What is a PCT system?

    The PCT system stands for Patent Cooperation Treaty – an international treaty that aims to create a uniform process for filing international patent applications. The system is administered by the World Intellectual Property Organization (WIPO) and has more than 150 countries involved, including Singapore. Singapore acceded to the treaty on 23 February 1995

    Benefits of PCT system:

    • Time and cost savings: The PCT system allows applicants to file a single patent application for patent protection in multiple Treaty countries, instead of having to file a separate application in each country. This saves time, costs and administrative procedures.
    • Postponement of national filing deadline: When filing a PCT application, the applicant has an additional 30 months to decide which country the applicant wants to protect the patent. This is valuable time for the applicant to assess the commercial potential of the patent and prepare for the national filing.
    • Simplified Process: The PCT system uses a common set of rules and procedures for all participating countries, which simplifies the filing process and saves time for both the applicant and the national patent office.
    • Early Search Information: The International Patent Search Office and Written Opinion will provide the applicant with information about the novelty and patentability of the patent, helping the applicant make an informed decision about the national filing.
    • Strengthening international cooperation: The PCT system encourages international cooperation in the field of patents by creating a common platform for the exchange of information and sharing of experiences between countries.
    • Innovation support: PCT systems help promote innovation by reducing the procedural burden on inventors and making it easier for them to protect their patents worldwide.

    Patent application through PCT system

    • PCT Application: Applications can be submitted in Vietnamese or English, however, it is recommended to be submitted in English to facilitate the processing process. You can download the PCT form from the WIPO website: https://www.wipo.int/pct/en/forms/

      • Patent Name Technical field
      • Patent summary
