On September 16, 2011, President Obama signed into law the Leahy-Smith America Invents Act. The Act imposes the most sweeping changes to the U.S. patent law in almost 60 years. This publication sets forth in Black Line format each change to Title 35 of the United States Code (patents) effected by the America Invents Act.
