Even a casual student of United States patent law developments during the past year unavoidably would have happened on multiple discussions of the Court of Appeals for the Federal Circuit´ s State Street Bank & Trust Co v Signature Financial Group (149 F3d 1368 (Fed Cir 1998)) decision, that held computer software for conducting methods for doing business to be patentable subject matter and not per se unpatentable subject matter. Not only has a majority of the US legal community positively responded to this decision because it addresses critical patentability questions involving software, but also technology owners have responded with increased patent application filings. By last December, the US Patent and Trademark Office reported that applications claiming inventions in a fashion similar to the claims in State Street Bank had increased by over 40% over the previous year and that it expected to issue over 300 patents with business method type software claims by October of this year. Unmistakably, the pump was primed even before the State Street Bank decision issued.
