The Mexican IP landscape is seeing major changes on multiple fronts. The most momentous is the United States–Mexico–Canada Agreement (USMCA), which is finally being ratified after lengthy negotiations between the parties. The trilateral agreement will usher in stronger obligations regarding IP protection. Two key revisions in the final agreement were the removal of an extended 10-year data protection clause for biologics and a provision requiring patents to be available for new uses of known drugs. These amendments will have profound implications for generic manufacturers and the practice of patent evergreening. The USMCA also includes a patent term adjustment provision, which seeks to remedy the regulatory delays that often affect applicants. An agreement has also been signed between the US Patent and Trademark Office and the Mexican Institute of Industrial Property (IMPI) which will expedite patent issuance for US patentees in Mexico. The bilateral cooperation will improve IMPI’s capacity to process applications and is likely to reduce prosecution time. Additionally, Mexico’s accession to the Hague System for Industrial Designs means that Mexican inventors can now register designs in the member states of the Hague System by way of a single application to the World Intellectual Property Organisation at no extra cost. Such changes are expected to attract greater foreign investment and reinvigorate the commercial outlook of Mexican manufacturers.
