Patent Office Guidance Post Bilski

Posted Wednesday, August 11, 2010 by Jim Ruttler

The U.S. Supreme Court reviewed the case and clarifed that the machine or transformation test was not the sole test for patentability. Instead, the Supreme Court held that any product or process is patentable so long as it isn’t an abstract idea. The Court further indicated that the machine or transformation test was a useful starting point when making determinations of patent eligibility, but that inventions that failed this test might still be patentable.
