Sui generis rights are designed to protect subject matters that cannot meet traditional intellectual property requirements, but that for some reasons still require protection. This is especially relevant for AI-generated worksAI-generated works. Therefore, this chapter explores existing sui generis rights as potential frameworks for protecting AI-generated works. First, it evaluates sui generis rights for the protection of traditional cultural expressionsTraditional cultural expressions in Indonesia and concludes that this model is unsuitable for AI-generated works because it emphasises community ownership and is often implemented locally. Second, it assesses suigeneris database rightsDatabase right in the European Union and finds that both database and AI-generated works protection aim to protect technological investmentInvestment rather than authorshipAuthorship. However, the sui generis database rights are only applicable within the EU, while generative AI necessitates globally-accepted regulations because its production, distribution, and consumption process often transcends national boundaries. Therefore, a comprehensive international framework is essential for the effective protection of AI-generated works.
