A trademark serves as a distinctive sign in commercial activities and holds significant economic value. In business practice, trademark owners may grant permission to other parties to utilize their marks through licensing agreements. However, in its implementation, licensing agreements frequently give rise to disputes between trademark owners and licensees. This study aims to analyze two primary issues: first, the essence of well-known trademarks according to the judges' considerations in the Supreme Court Decision No. 1758 K/Pdt/2010 concerning trademark licensing agreements; second, the legal implications and remedies in handling disputes related to well-known trademark licensing agreements. This study employs a normative legal research method using a statutory approach and a case approach, analyzing the provisions in Law Number 20 of 2016 concerning Trademarks and Geographical Indications. The results indicate that legal protection for well-known trademarks aims to safeguard the exclusive rights of the trademark owners. The judges ruled that the licensee has no right to use the trademark once the licensing agreement has expired or if the licensee fails to fulfill the agreed obligations.
