This week, the U.S. Department of Justice Antitrust Division celebrates the 20th anniversary of World Intellectual Property Day. The division marks the occasion by remembering the revolutionary ideal that our nation’s founding fathers embedded in the U.S. Constitution: that “securing . . . to Authors and Inventors the exclusive Right to their respective Writings and Discoveries” will “promote the Progress of Science and useful Arts.” For over 200 years, this “exclusive Right” has served as the foundation of the U.S. system of patent, copyright, and trademark laws.
