Changes To Implement the First Inventor To File Provisions of the Leahy-Smith America Invents Act

The Leahy-Smith America Invents Act (AIA) amends the patent laws pertaining to the conditions of patentability to convert the U.S. patent system from a "first to invent" system to a "first inventor to file" system; treats U.S. patents and U.S. patent application publications as prior art as of their earliest effective U.S., foreign, or international filing date; eliminates the requirement that a prior public use or sale be "in this country" to be a prior art activity; and treats commonly owned or joint research agreement patents and patent application publications as being by the same inventive entity for purposes of novelty, as well as nonobviousness. The AIA also repeals the provisions pertaining to statutory invention registrations. The United States Patent and Trademark Office (Office or USPTO) is revising the rules of practice in patent cases for consistency with, and to address the examination issues raised by, the changes in section 3 of the AIA.
