Thailand Patent Registration

What is a Patent?

A Patent is an important document that the Government Office issues to grant protection for an invention or a design.  Patents are a form of intellectual property.


An invention is any innovation which creates a new or improves a known product or process.


A design is any form or composition of lines or colors which gives a special appearance to a product and can serve as a pattern for a product of industry or handicraft.


What types of Patents does Thailand recognize?

You may register Patent for Invention, Design Patent, and Petty Patent.

Patent for Invention is the protection of feature, improvement, and components of product or process.

Design Patent is for creativity protection concerning features pertaining to the shape, color, configuration or pattern of an item.

Petty Patent is for new product or process, improvement with moderate technological development or low level of innovation with some more utilization.


Is Thailand Patent registration compulsory?

Thailand does not officially require Patent registration. However, there are certainly many benefits that you can consider.


What are the advantages of registering Patents?

First of all, registering Patent provides greater legal protection against infringement because it protects the inventions and designs.  Registered Patents therefore solely grants the patent owner the rights to produce as well as to distribute such product for a limited time.

When you register a patent, it deters others from using the same production idea because the registered patent will appear in the patent search system. Hence, this will likely discourage others from proceeding to register similar Patent.

Once registered, it then provides the patent owner with greater remedies. As a result, it increases the likelihood of the successful filing of a dispute resolution case from an infringer.

  • the invention is new;
  • it involves an inventive step; and
