Trademark Act B.E. 2534  
Remarks: The reasons for enactment of this Act are as follows.  The Trademark Act  
B.E. 2474 had been promulgated and enforced for a long time. The provisions are obsolete 
and cannot protect the rights of the trademark owner efficiently. Also, the service mark  
the certificatio n mark and trademark or service mark license are being widely known and 
legally protected in many countries, are still not protected under Thai law. Furthermore  
the aforementioned Act has some  inadequate provision s, such as, power and duties of 
Registrars  and Trademark Board as well as the right of applic ants are not expressly legalized . 
This absence causes a lot of difficulties in practice . It is expedient the revise the Act. It is, 
therefore, necessary to enact this Act.

Trademark Act (No. 2) B.E. 2543  
Remarks: The reasons for enactment of this Act are as follows. The plurilateral trade 
nego tiation at Uruguay Round where many countries had agreed on TRIPS and the 
establishment  of World Trade Organization  (WTO)  had been achieved with success  and came 
into force. Therefore, Thailand, as a member of WTO, has an obligation to implement the 
aforem entioned agreement in order to achieve an efficient protection of intellectual property. 
Also, it is expedient to revise the conditions, characteristics and the prohibitions of 
registration of trademarks , the cancellation and the related procedures, the co llection of 
publication’s fee and the composition, power and duties of the Trademark Board, as well as 
to provide for the assignment of the officer under this Act and to enhance  the power of 
Registrar in considering the opposition to the registration.  It is, therefore, necessary to enact 
this Act.  
Section 27  Any trademark applications, service mark application, certification 
mark application and collective mark application, which are filed before the entry into force 
of this Act, shall be deemed applic ation s under the Trademark Act  B.E. 2534, amended by

69 Trademark Act (No. 3) translated by Boonma Tejavanija  - 34 - 
 
Remarks: The reasons for enactment of this Act are as follows. N owada ys, protection of 
trademarks at the international level extends to new types of marks which are not covered by 
the provisions of the Trademark Act B.E. 2534. Also, as Thailand would accede to the 
Protocol Relating to the Madrid Agreement Concerning th e Int ernational Registration of 
Marks (Madrid Protocol) the salient feature of which provides for the filing of a single 
international application for protection of trademarks, service marks, certification marks and 
collective marks in the member states, i t is expedient to expand the scope of trademark 
protection and to amend the provisions of the relevant part of this Act to conform to the said 
Madrid Protocol. Besides, as packagings or utensils bearing another person’s registered 
trademark, certification mark or collective mark are used deceptively thus causing damage to 
the public and the said trademark owner, it is expedient to penalize and determine penalty for 
the said act.  It is also expedient to revise the registration procedure and time period for m ore 
clarity and explanation and to amend the official fees annexed to the Act for more 
appropriateness. It is, therefore, necessary to enact this Act.
