Design Patent In Thailand

Bangkok, ThailandDesign rights are the exclusive rights granted temporarily, to the creator, for a form of creation, involving a mix of colors and lines, giving a distinct appearance to a product, good, or handicraft. Registration of design rights may be obtained to ensure protection to the distinctive characteristic of the product, be it its design, shape, color, pattern, creation, configuration, ornament, or embellishment so applied to it, by an industrial process or otherwise.

In Thailand, the design rights, are granted under the Design Patents, based on a ‘novel’ characteristic, which have not been in use, knowledge, or resemblance within Thailand or any other country, prior to the filing of the claim. Therefore, for it to qualify for a valid protection license under Thailand, the proposed design must comply with:

The presence of novelty, which does not conform to the State of the Art, as:

  1. an invention which was widely known or used by others in the country before the date of application for the patent;
  2. an invention the subject matter of which was described in a document or printed publication disclosed to the public in Thailand or in a foreign country before the date of application for the patent (for example in a scientific magazine or thesis);
  3. an invention for which a patent was granted in Thailand or overseas;
  4. an invention for which a patent was applied in a foreign country more than eighteen months before the date of application for the patent;
  5. an invention for which a patent was applied in this or a foreign country and the application was published before the date of the application.

The design in question must be capable of industrial application, not merely academic or theoretical.

As per the covenants of the Paris Convention, the right of the priority application is also valid within Thailand, allowing the applicants to file for a design patent within Thailand, retrospectively on the same date, like that of filing in any other country which is also a signatory to the Paris Convention or otherwise (subject to appropriate approvals).
