About Patent Law in Thailand

Patent law in Thailand is governed by the Patent Act B.E. 2522 (1979), with subsequent amendments reflecting international standards and agreements. Patents in Thailand protect inventions, utility models, and designs, allowing inventors or patent holders to exclude others from making, using, or selling the invention without permission for a certain period. Patents in Thailand are crucial for fostering innovation, protecting intellectual property, and ensuring that inventors can gain benefits from their creations.

Why You May Need a Lawyer

Navigating patent law can be complex. You may require legal help if you are seeking to:

  • File a patent application: Ensuring your invention is correctly documented and meets all legal requirements.
  • Defend against patent infringement: Taking legal action if someone illegally exploits your patented invention.
  • Enforce your patent rights: Protecting your investment and innovation from unauthorized use.
  • Engage in licensing or selling your patent rights: Structuring agreements that maximize your return while protecting your intellectual property.
  • Resolve disputes over patent rights: Mediation or litigation in a legal setting regarding patent issues.

Local Laws Overview

Key aspects of Thai patent law include:

  • Patentability Requirements: Inventions must be new, involve an inventive step, and be capable of industrial application.
  • Patent Duration: Inventions are protected for 20 years, and designs for 10 years, from the filing date.
  • Exclusions: Some inventions, like natural discoveries, scientific theories, methods of treatment, and business methods, are non-patentable.
  • Compulsory Licensing: Under certain conditions, the government can allow others to use a patented invention without the consent of the patent holder.
  • International Treaties: Thailand is a member of the Paris Convention and the Patent Cooperation Treaty, allowing for international patent applications and protection.
