Universal Cipher (formerly Cumberland Systems) patent determined to be likely invalid

On July 16, the Patent Trial and Appeal Board (PTAB) instituted trial on all challenged claims in an IPR filed by Unified against US Patent 8,023,647, owned by Universal Cipher LLC, an NPE (f/k/a Cumberland Systems, a Brad Liddle entity). The ’647 patent, directed to encrypting of a password or other secret information, has been asserted in twenty-four district court cases, all of which have been terminated.    

Unified is represented by Ropes & Gray in this proceeding. View district court litigation for the ‘647 patent. To read the petition and view the entire case proceeding, see Unified’s Portal
