Federal Circuit Finds Application of Printed Matter Doctrine Too Expansive, PTAB Litigation Blog
Visit the PTAB Litigation Blog
During an inter partes review (IPR) initiated by Ingenico, the PTAB found certain claims from three patents held by IOEngine to be unpatentable. The patents at issue are directed to secure communications for portable devices used with a terminal (e.g., desktop computer) for user input. On appeal (IOENGINE LLC v. Ingenico Inc), IOEngine argued that the PTAB incorrectly construed “interactive user interface” and incorrectly applied the printed matter doctrine. While rejecting the claim construction arguments, the Federal Circuit held the PTAB misapplied the printed matter doctrine.
