Patently-O’s recent post for a good overview of the legislation. It has been reported that the President is likely to sign the Smith-Leahy America Invents Act into law in the next few days. The most significant change will be to move from a first-to-invent country toward a first-to-file country. This change will greatly affect U.S. practitioners’ patent procurement and litigation strategies. See http://www.patentlyo.com/patentreformbillaspassed.pdf for the language of the Act.
