THE DEATH OF STATE STREET

9 Wake Forest Intell. Prop. L.J. 61

This article reflects upon the 10 year anniversary of the Supreme Court opinion in State Street Bank & Trust Co. v. Signature Financial Group, Inc., which held that mathematical algorithms are patentable under § 101 of the Patent Act as long as they have “practical utility” and there is no “business method exception.” In the article, Guntersdorfer considers the Supreme Court and Federal Circuit cases that followed, including last year’s en banc review of In re Bilski, which arguably put the State Street decision to rest.
