Last week’s US Supreme Court decision in Alice Corp. v. CLS Bank International invalidated four of Alice Corporation’s patents, but stopped short of an overarching ruling on the patent eligibility of software. Petitioner Alice Corp. has been battling CLS Bank since 2007 over four patents related to transaction settlements made through a third-party electronic intermediary (5,970,479, 6,912,510, 7,149,720, 7,725,375). After both a district judge and the Federal Circuit Court ruled Alice’s claims to be too abstract for patent eligibility under Section 101 of the Patent Act, Alice Corp. petitioned the Supreme Court for a writ certiorari in September 2013.
