The past year has seen a raft of game-changing developments on the Mexican legal landscape, with plenty to keep IP practitioners on their toes. Perhaps most momentous of all was the September 2018 signing of the United States-Mexico-Canada Agreement (USMCA), which is set to supersede the North American Free Trade Agreement and currently awaiting ratification by all three countries. Under the USMCA, patent owners will enjoy longer terms of protection and will be entitled to term adjustments in the event of registration delays. In addition, biologics – which were previously not explicitly covered by Mexican law – will now benefit from a 10-year protection term. The agreement has been widely applauded for providing greater certainty to rights holders, which should in turn bring more investment into the country and reinforce its innovation scene. Debate has also been ongoing with respect to the patent linkage system between the Mexican Intellectual Property Institute (IMPI) and the Federal Commission for the Protection against Sanitary Risk, although much remains to be done to increase confidence surrounding the interaction of drug patents with health regulations. Despite this, strong efforts are being made to establish a reliable linkage system to encourage healthcare and patent authorities to take all available measures to maximise the impact of healthcare innovation.
