Unified Patents files to invalidate PersonalWeb’s patent in the Cloud Storage space

Unified has been monitoring PersonalWeb's activity in the cloud storage space for some time as part of our continued efforts to deter NPEs. Since 2011, PersonalWeb (www.personalweb.com) has filed over a dozen litigations against cloud storage technologies and services.

On April 15, 2014, Rackspace's Inter Partes Review (IPR) against PersonalWeb's US Patent 5,978,791 (assigned docket # IPR2014-00057) was instituted against all challenged claims. Today, Unified filed its own IPR (assigned docket # IPR2014-00702) against the '791 patent along with a motion to join Rackspace's IPR. A copy of the filed petition and motion can be viewed below.
