Patent systems and patent laws exist to promote investment in and development of technology. The recently-enacted America Invents Act (AIA) and certain U.S. Supreme Court decisions over the last 5 years have brought the most dramatic changes to U.S. patent law in more than 50 years. This course focuses on the fundamentals of U.S. patent law including patentability, infringement, inventorship, and ownership. The course will also explore some of the underlying themes in patent law as well as the purpose of and justifications for a patent system. The course reading includes the patent statute (Title 35 of the United States Code) both pre-AIA and post-AIA and selected case law primarily from the U.S. Supreme Court and U.S. Court of Appeals for the Federal Circuit. The course will generally address both the procurement and enforcement of U.S. patents. Although this course will cover the legal principles underlying patent claim drafting and patentability, this course will not focus on patent practice and procedure. Hybrid Juris Doctor students cannot take this course for an S/U grade.
