Entrepreneurs use religious names and symbols to trademark their businesses so that they are easy to remember and have commercial value. A trademark is a symbol used by a wholesaler, becoming a recognizable name or symbol to identify a product or service distributed to the marketplace. Trademarks make a product easily recognizable because it is unique and different from other businesses. A trademark identifies a product as belonging to a specific firm and recognizes the company's ownership of the mark. In Indonesia, religious names and symbols have been used as trademarks. Even if utilizing religious symbols generates discontent and outrage among the public, many enterprises already hold trademark certificates. The study seeks to determine whether religious names and symbols can be used as trademarks, as well as the legal ramifications of objections to utilizing holy names and symbols as trademarks. According to Article 20 of the Law of the Republic of Indonesia No. 20 of 2016 on Marks and Geographical Indications, a mark cannot be registered if it is incompatible with state ideology, rules, regulations, morality, religion, decency, or public order. As a result, using names and religious symbols in business is against the law. In this situation, it may be considered religious blasphemy, as defined in Article 156a of the Criminal Code concerning Blasphemy/Defamation of Religion jo. President of the Republic of Indonesia Stipulation Number 1 of 1965, changed into Law Number 1 of 1965 Concerning Religious Abuse and/or Blasphemy.
