Patent Infringement in Thailand: Protecting Invention and Petty Patents

Patent infringement poses significant challenges for inventors and businesses striving to protect their intellectual property and secure their competitive edge. In Thailand, patents play a vital role in fostering innovation and economic growth, offering inventors exclusive rights over their creations. The legal framework for patent infringement in Thailand provides strong protections for patent holders, enabling them to enforce their rights while also balancing societal and economic interests through well-defined exceptions. These provisions ensure a fair balance between encouraging innovation and maintaining accessibility to technology and knowledge.

Invention patents and petty patents are two crucial tools for intellectual property protection in Thailand. While invention patents safeguard groundbreaking and industrially applicable innovations, petty patents are tailored for simpler yet valuable improvements that may not meet the high inventiveness threshold required for invention patents. Together, these systems provide comprehensive protection, ensuring inventors of all scales can secure their rights.

Understanding patent infringement in Thailand requires a deep dive into the rights of patent holders, the scope of protection afforded under the law, and the legal nuances that govern unauthorized use. This knowledge is essential for innovators seeking to defend their intellectual property, businesses aiming to navigate compliance, and professionals working to resolve disputes effectively.

What Constitutes Patent Infringement?

Under Section 36 Paragraph 1 of the Thai Patent Act, patent infringement is defined as the unauthorized use or exploitation of the exclusive rights granted to a patentee. These rights are designed to protect the commercial value and integrity of patented inventions, ensuring that only the patentee has the authority to control their use, production, and distribution. This protection applies to both patented products and processes, creating a comprehensive framework to safeguard intellectual property.

When the subject matter of a patent is a product, the patentee holds the exclusive right to produce, use, sell, possess for sale, offer for sale, or import the patented product. Any act that falls within these rights, if carried out without the patentee’s consent, constitutes infringement. This includes unauthorized manufacturing, commercial use, or marketing of the patented product. By enforcing these rights, the law ensures that patentees can fully benefit from the market exclusivity of their invention.

In cases where the patent covers a process, the patentee’s rights extend beyond the use of the process itself. They also include control over the production, sale, use, possession for sale, offering for sale, or importation of products produced by the patented process. Infringement occurs not only when the process is used without authorization but also when the resulting products are distributed or commercialized without the patentee’s permission. This broad protection prevents unauthorized parties from bypassing patent rights by exploiting the economic value of a patented process indirectly.

For both product and process patents, infringement hinges on the act being unauthorized and falling within the scope of the claims granted under the patent. Thai law ensures that patentees can protect their innovations from both direct and indirect exploitation, maintaining the integrity of their intellectual property rights. This robust framework not only fosters innovation but also ensures a fair and competitive market for businesses relying on patented technologies.

Exceptions to Patent Infringement

Thai patent law provides several exceptions to infringement under Section 36 Paragraph 2, designed to balance the exclusive rights of patent holders with societal interests and practical considerations. These exceptions allow certain activities to be carried out without being deemed infringements, provided they align with specific conditions outlined in the law.

One key exception covers acts undertaken for the purpose of study, research, experimentation, or analysis. These activities are permitted as long as they do not unreasonably conflict with the normal exploitation of the patent or cause undue prejudice to the legitimate interests of the patent owner. This provision is intended to promote scientific progress by enabling researchers to explore patented inventions for academic or experimental purposes without violating the law.

The law also protects individuals or businesses that, in good faith and without knowledge of a pending patent application, produce a patented product or use a patented process before the patent application is filed in Thailand. These users are allowed to continue their activities, provided they acquired the necessary equipment or began production before the application date. This exception ensures fairness for those who were unaware of the patent and had already invested in using or developing the technology.

Another exception pertains to the compounding of pharmaceuticals. Professional pharmacists and medical practitioners are allowed to compound drugs specifically to fulfill individual prescriptions without infringing on the patent. This exemption ensures that medical practitioners can address patient needs without being restricted by patent limitations.

Activities related to drug registration are also excluded from infringement. This exception allows applicants to prepare for the commercialization of pharmaceutical products after the patent term expires, such as conducting registration activities or submitting regulatory approvals. By permitting these preparatory steps, the law facilitates a smoother transition to the market once the patent protection ends.

Patented devices used temporarily in transport vehicles, such as vessels, aircraft, or land vehicles, are exempt when the vehicles enter Thailand accidentally or temporarily. These devices must be used exclusively for the needs of the vehicle and not for any broader commercial purpose. This exception applies to vehicles from countries that are parties to international conventions on patent protection, ensuring compliance with global standards.

Finally, the principle of exhaustion of rights provides that once a patented product is sold or authorized for sale by the patentee, the subsequent use, resale, or importation of that product is not considered infringement. This principle ensures that patent holders cannot exercise excessive control over the distribution of their products after the initial authorized sale, thereby promoting market fairness.

These exceptions collectively strike a balance between the interests of patent holders and broader public benefits, ensuring that patent rights do not create unnecessary barriers to scientific, medical, or commercial progress.

Scope of Protection and Claim Interpretation

The scope of protection for a patented invention in Thailand is governed by Section 36 bis, which defines the boundaries of the patentee’s exclusive rights. This provision highlights the critical role of claims in determining the extent of legal protection while also addressing how descriptions, drawings, and the doctrine of equivalents contribute to interpreting those claims.

Section 36 bis Paragraph 1 establishes that the scope of a patent is primarily determined by its claims. Literal infringement occurs when a third party’s actions fall squarely within the language of the claims. In such cases, the accused product or process reproduces all elements or features specified in the claims exactly as they are described. The claims, therefore, act as the legal boundary for what constitutes direct and unequivocal infringement. However, these claims cannot be interpreted in isolation. The description and drawings accompanying the patent application provide essential context, helping clarify technical aspects and ensuring that the claims accurately reflect the full scope of the invention.

Section 36 bis Paragraph 2 expands the scope of protection by introducing the doctrine of equivalents. This principle extends the patentee’s rights beyond the exact wording of the claims to features that, while not explicitly mentioned, perform substantially the same function in substantially the same way to achieve substantially the same result. Unlike literal infringement, which depends on a direct match to the claims, the doctrine of equivalents protects against minor modifications or substitutions designed to circumvent the literal scope of the claims. For instance, if an accused product or process operates in a way that is functionally equivalent to the patented invention, it may still fall within the scope of the patent despite superficial differences.

Together, literal infringement and the doctrine of equivalents create a balanced framework for enforcing patent rights. Literal infringement provides clear, strict boundaries for determining when a patent is violated, while the doctrine of equivalents prevents potential infringers from exploiting minor variations to bypass those boundaries. This dual approach ensures that patentees can effectively protect their innovations while allowing the patent system to address the complexities of real-world applications.

By combining these principles, Section 36 bis provides a comprehensive system for defining and enforcing the scope of patent protection. This ensures that patents remain robust and adaptable, safeguarding the rights of inventors while fostering continued innovation in Thailand.

Pre-Grant Infringement and the Rights of Patent Applicants

Pre-grant activities, or actions taken before a patent is formally granted, can under certain conditions constitute patent infringement as outlined in Section 35 bis of the Thai Patent Act. This provision provides patent applicants with a level of protection during the pendency of their application, ensuring their inventions are safeguarded even before the official grant of patent rights. However, the scope and enforceability of these protections are carefully defined to balance the interests of the applicant and third parties.

Section 35 bis specifies that any act violating the exclusive rights provided under Section 36 is not automatically deemed an infringement during the pre-grant phase. For such actions to be considered infringement, the invention must have been published in the Thai Patent Gazette in accordance with Section 28, which ensures that the claims of the application are publicly accessible. Furthermore, the alleged infringer must either have knowledge of the patent application’s existence or have been formally notified in writing. These conditions ensure that potential infringers cannot claim ignorance of the pending patent.

The rights provided under Section 35 bis are not without limitations. While the applicant may seek damages for activities that qualify as pre-grant infringement, such damages can only be claimed after the patent or petty patent is officially granted. This stipulation ensures that legal recourse is only available to applicants who ultimately receive patent protection, avoiding undue burdens on third parties for actions taken during the application phase. Applicants must also bring such claims before the court to secure compensation, ensuring that the process is subject to judicial scrutiny.

By addressing the rights of patent applicants during the pre-grant period, Section 35 bis offers a balanced approach to protecting innovations while maintaining fairness for all parties involved. This provision reinforces the integrity of the patent system by providing a framework for addressing unauthorized use of pending inventions without granting premature enforcement rights.

Conclusion
