Patent: A Comprehensive Reform for Modernizing Patent Registration
Introduction
Thailand’s current Patent Act, enacted in 1979 (B.E. 2522) (“Act”), has been the cornerstone of the country’s intellectual property (IP) protection system for over four decades. However, with the rapid evolution of technology and global trade, the Act has become outdated and no longer aligns with international standards. To address these challenges, Thailand is proposing a significant amendment to its Patent Act, known as the Draft Patent Act B.E. …. (“Draft”). This reform aims to modernize the patent registration process, reduce time and costs, and align Thailand’s IP framework with international agreements, such as the Hague Agreement Concerning the International Registration of Industrial Designs.
This article provides an overview of the key changes proposed in the Draft, focusing on the prosecution processes for invention patents, design patents, and petty patents, and highlights the potential impact of these reforms on innovation and IP protection in Thailand.
The Proposed Prosecution Process for Invention Patents
The Draft introduces several key changes to the prosecution process for invention patents, aimed at improving efficiency and reducing delays:
- Revised Examination Criteria and Procedures: The criteria and procedures for preliminary and substantive examinations will be updated. These details will be outlined in the new ministerial regulation once the Draft is enacted.
- Shortened Timelines:
- The initial examination period will be reduced to 18 months, leading to the first publication.
- Applicants must request substantive examination within 3 years (down from 5 years) from the date of filing of the application.
- Patents will be issued within 90 days of the second publication.
- Third-Party Observation: The Draft introduces a new mechanism allowing third parties to submit evidence if they believe the pending patent application lacks novelty. This can be done from the date of the first publication until the completion of the substantive examination.
- Elimination of Patent Issuance Fees: The Draft removes the patent issuance fee, reducing the financial burden on applicants.
The Proposed Prosecution Process for Design Patents
The Draft proposes a more streamlined process for design patents, distinguishing it from the current system, which shares the same process as invention patents:
- Combined Examination Process: The substantive examination will be conducted alongside the initial examination, prior to the publication of the patent application.
- Shorter Publication Period: The publication period for design patents will be reduced from 90 days to 60 days. If no opposition is filed within this period, the patent will be granted.
- Elimination of Patent Issuance Fees: Similar to invention patents, the Draft removes the issuance fee for design patents.
The Proposed Prosecution Process for Petty Patents
The Draft maintains the existing process for petty patents, but introduces a few notable changes:
- Extended Examination Request Period: Interested parties may request a substantive examination within 6 years (instead of 1 year) from the date of publication.
- Elimination of Fees: The Draft removes the publication and issuance fees for petty patents, making the process more cost-effective.
Conclusion
The proposed amendments to the Act represent a significant step forward in modernizing the country’s IP protection system. By streamlining processes, reducing costs, and aligning with international standards, the Draft aims to foster innovation and attract foreign investment. The introduction of mechanisms such as third-party observation enhances transparency and fairness, while the shortened timelines for design patents demonstrate Thailand’s commitment to efficiency.
The Draft is currently under the first public hearing process, which will be ended on 31 January 2025. Stakeholders, including inventors, businesses, and legal professionals, are encouraged to participate in the consultation process to ensure that the final version of the Draft meets the needs of all parties involved.
The Draft is poised to strengthen the country’s position as a hub for innovation and intellectual property protection in Southeast Asia, paving the way for a more dynamic and competitive economy.
