Thailand

Types of protection

Patent of Invention: Patents may be granted for innovation that is new and inventive with an industrial application.  Applications not in Thai must be translated and submitted to the Department of Intellectual Property within 90 days of filing. They are granted for a term of 20 years from the filing date.

Petty Patent: This is similar to the utility model and applies to less complicated inventions. To be eligible for a petty patent, an invention need only be new and have an industrial application. Petty patents carry a term of 10 years from the date of filing.

Product Design Patent: A Product Design Patent protects the ornamental aspects or aesthetics of an article including features pertaining to the shape, configuration or pattern. This type of patent has a 10-year term of protection from the filing date.

Plant varieties: In Thailand, the length of time it takes for a plant to mature for cultivation determines the term of protection. This can vary from 12, 17 or 27 years from the date of filing.1
