Patents
TYPES OF PROTECTION :

PATENTS

Kind : Inventions and designs
Duration :     Inventions 20 years, designs 10 years, from date of application in Thailand

PETTY PATENTS
Kind : Inventions and designs
Duration :     Inventions 20 years, designs 10 years, from date of application in Thailand
APPLICANT : Inventor or assignee

NOVELTY : Not publicly known or used in Thailand or published abroad. For inventions (patents and petty patents), no corresponding foreign application filed more than 18 months before the Thai application.

Exception : unlawful disclosure or disclosure at an official exhibition or by the inventor within 12 months prior to the Thai application.
 
UNPATENTABLE INVENTIONS : Naturally occurring microorganisms and their components, animals, plants, animal and plant extracts (but processes are patentable), computer programs, methods of diagnosis or treatment of human and animal diseases (but those applying to plant diseases are patentable).

PRIORITY : Thailand became a member of the PCT on December 24, 2009.

A PCT application filed before December 24, 2009 cannot enter the national phase in Thailand. A PCT application filed on or after December 24, 2009 can enter the national phase in Thailand even though it claims priority from a foreign application filed before December 24, 2009. However, it must enter the national phase in Thailand within 30 months from the date of first filing (the priority date of the PCT application).

An invention will lose novelty if it has been disclosed in a published document or printed matter or by any other means prior to the filing date of the Thai application (or the priority date, if claimed). Thailand has an “absolute novelty” requirement and there is no grace period for publication made before filing application in Thailand.

Priority can be claimed by citizens of all WTO and Paris Convention member countries no matter where the first application was filed, provided that the Thai application is filed within twelve months following the first filing date.
