In September, 2011, the Leahy-Smith America Invents Act, Pub. L. 112-29, was signed into law. The U.S. Patent and Trademark office has prepared an indepth resource guide on the implementation of this act which is available on their website. The guide includes a complete legislative history of the act, including bills, Senate & House debates and hearings. Over the next couple of months, the USPTO will be traveling throughout the country to discuss proposed rules for implementation of the act and their scheduled presentations are highlighted here as well.
