Patent registration in Thailand

The number of patent registration in countries is increasing. This is attributed to the increasingly interconnected global economy, which makes it easier to share ideas and patents. This leads to increased competition, prompting individuals and businesses to file patent applications to protect their intellectual property. Besides, the rapid development of technology has led to the birth of many new products and processes. This led to an increase in the number of patents registered, as inventors wanted to protect their new ideas. According to the Intellectual Property Development Department of Thailand (DIP), the number of patent applications in Thailand has steadily increased over the years. In 2022, Thailand recorded 24,103 patent applications, up 4.7% from 2021. High-tech sectors such as electronics, telecommunications, and biotechnology attract the most patent applications. In 2022, the electronics sector accounted for 23.2% of all patent applications, followed by telecommunications (18.5%) and biotechnology (11.7%). The patent activity of the enterprise is also developing strongly. In 2022, Thai businesses filed 15,166 patent applications, accounting for 62.9% of the total applications.

    Patent registration in Thailand 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 participating, including Thailand. Thailand acceded to the treaty on 24/12/2009

    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.
