Examination Guidelines for Implementing the First Inventor To File Provisions of the Leahy-Smith America Invents Act

The United States Patent and Trademark Office (Office) is publishing examination guidelines concerning the first inventor to file provisions of the Leahy-Smith America Invents Act (AIA). The 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 patents and 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 activity 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.
