Types of Patents in Thailand

The Thailand Patent Act provides protection for creators of inventions, designs and petty patents in Thailand, whereby the patent is non-renewable after the initial period of protection:

  • Invention patent applications must describe the invention of a new product or process, or an improvement thereof, and one or more claims that define the invention. The claims must meet the requirement of novelty and non-obviousness. The protection period is valid for 20 years.
  • Design patents are to protect ornamental aspects or aesthetics of an article including features pertaining to the shape, configuration or pattern, for which the protection is valid for a 10-year period.
  • Petty patents are for new inventions that would qualify for an invention patent, except that they have no strong, technical innovative step involved. The protection period is valid for 10 years.
