The America Invents Act (AIA) – signed into law on September 16, 2011 – introduced significant changes to U.S. patent law, including changes to patent litigation rules and U.S. Patent and Trademark Office (USPTO) procedures. Some of the changes, particularly those related to patent litigation (such as limitations on joinder of defendants, the elimination of the best mode invalidity defense, an expansion of the prior use defense, and provisions regarding proof of willful and induced infringement), went into effect immediately.
