"Since the United States Supreme Court first addressed the patentability of computer software in Gottschalk v. Benson the law surrounding the patentability of software has changed considerably, leaving many to wonder whether software is patentable at all. Originally in Benson, the Supreme Court decided that software was not patentable, but then later retracted the blanket prohibition against patenting software. The Federal Circuit then spent the better part of two decades trying to figure out under what circumstances software (or computer related processes) should be patented. This seemed to culminate in the 1998 ruling of the Federal Circuit in State Street Bank & Trust Co. v. Signature Financial Group, Inc. Unfortunately, the waters were once again made murky as a result of the 2008 ruling by the Federal Circuit in In re Bilski."
