The Intellectual Property (IP) chapter of the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) is recognized for its extensive coverage, encompassing a broad range of innovation areas such as patents, trademarks, geographical indications, and copyright. This chapter sets a new global benchmark for IP protection, posing significant challenges to the existing legal frameworks of member countries and necessitating rapid adaptation, particularly for developing members like Vietnam, Malaysia, and Mexico. These nations have undertaken comprehensive revisions to their IP laws to align with the international standards established by the CPTPP. Despite their unique national contexts, the legal amendments reflect distinct strategies and methodologies in meeting international standards. This paper conducts a qualitative analysis of Vietnam, Malaysia, and Mexico, comparing their law amendment strategies, contents, and techniques across three dimensions. It highlights the distinctive characteristics and impacts of their legal revisions, offering valuable insights for other prospective developing members within the CPTPP framework on the practice of IP law reform.
