The protection of well-known trade marks in Indonesia is regulated by Article 4, Article 6 paragraph (1.b) and Article 6 paragraph (2) of the Trade Mark Law No 15 of 2001. According to Article 4, a trade mark shall not be registered on an application made by an applicant with bad faith. Meanwhile, Article 6 paragraph (1.b) states that an application shall be rejected by the Directorate General of Intellectual Property Rights of Indonesia if the trade mark is similar in principle or in its entirety to an already well-known trade mark owned by another party for goods and/or services of the same type. The rejection of an application whose similarity in principle or in entirety to a well-known trade mark for goods and/or services of the same type is determined by observing the public's general knowledge of the trade mark in the particular business sector. In addition, it is necessary to observe the reputation of the well-known trade mark which can be achieved through intensive and extensive promotions and investments in a number of countries by its owner, and also evidenced by the trade mark registration in several countries.
