From the Background: "The United States-Mexico-Canada Agreement (USMCA) is a proposed free trade agreement (FTA) negotiated among the three parties to update and replace the 1994 North American Free Trade Agreement (NAFTA). [...] USMCA would make notable changes to NAFTA provisions on intellectual property (IP)--creations of the mind embodied in physical and digital objects. IPR [intellectual property rights] are time-limited rights that governments grant to inventors and artists to exclude others from using their inventions and creations without permission. [...] IP-intensive goods and services are an important part of U.S. trade with Canada and Mexico. The United States has expressed concern over certain IPR policies in both countries in recent years."
