Vindolor LLC patent challenged as likely invalid

On December 31, Unified, represented by Akin Gump, filed a petition for inter partes review (IPR) against U.S. Patent 6,213,391 asserted by Vindolor, LLC (an NPE). The ‘391 patent, directed to a portable system for electronic personal identification and authentication using a uniquely identifying trait of the user (such as biometric information), has been asserted in 11 district court cases against such companies as Petco, Walt Disney, Restoration Hardware, Verifone, Trader Joe’s, and others.
