  • On September 8, 2011, the U.S. Senate approved a landmark bill to reform the nation’s patent system, entitled the “Leahy-Smith America Invents Act,” which was previously passed by the U.S. House of Representatives on June 23, 2011. President Obama is expected to sign the bill into law very soon. This legislation will change the U.S. patent system in several fundamental ways, including, (1) a groundbreaking transition from a “first-to-invent” to a “first-inventor-to-file” system, (2) a sweeping overhaul of the patent office's post-issue review and examination regime and (3) substantial modifications to the procedural and substantive provisions governing litigants involved in patent infringement proceedings.
