The latest push to amend the U.S. statute to clear up some issues with patent eligibility is gaining momentum on Capitol Hill, but patent attorney Michael Borella said during an Aug. 20 webinar that the current legislation fails to adequately define the term "useful." The legislation defines "useful" as anything that provides "specific and practical utility," but Borella said that, assuming this definition holds, "I think we're going to end up with a diet version of the Alice test," a reference to a Supreme Court ruling that has invalidated a large number of patents.
