On August 29, Unified Patents (Unified) filed an inter-partes review (IPR) against patent owner PanTaurus, LLC (PanTaurus ) in order to protect cloud storage technologies from NPE activity. PanTaurus claims its patent covers computer architecture that selectively disables the alteration of data on a storage device for security purposes.
PanTaurus filed 16 cases against companies on April 23, 2014, in the Eastern District of Texas. Unified believes that the prior art used in its August 29th IPR shows that PanTaurus' patent, U.S. Pat. No. 6,272,533 ('533 patent), should never have issued. Unified's IPR challenges claims 29, 31-36, 38, 39, 42, and 43 of the '533 patent.
