CryptoPeak patent challenged as likely invalid

On November 22, 2017, Unified filed a petition for inter partes review (IPR) against U.S. Patent 6,202,150 owned and asserted by CryptoPeak Security, LLC, a Brian Yates entity and well-known NPE. The '150 patent, directed to “asymmetric (or public key) cryptosystems (“PKCs”)—in a public key infrastructure (“PKI”) environment,” has been asserted in 78 district court cases, 9 of which were pending at the filing of Unified's petition. The '150 has been asserted against such companies as 1-800 CONTACTS, Gamestop, Tractor Supply Co., Cabelas, MGM Resorts and Papa John's, among others.
