BUSINESS-METHOD EXCEPTION

business-method exception.Intellectual property. The traditional doctrine that business methods are not protected by intellectual-property laws. • Early caselaw established that “pure methods of doing business” were unpatentable. But in 1998, the Federal Circuit held in State St. Bank & Trust Co. v. Signature Fin. Group (149 F.3d 1368) that business methods are not per se unpatentable if they otherwise meet the requirements for a valid patent. The European Patent Convention expressly excludes business methods from patent protection. [Cases: Patents  7.14.
