Less than two weeks after Amazon and others filed a petition for inter partes review (IPR) of ZitoVault, LLC’s only patent-in-campaign (IPR2016-00021), the NPE has asserted the patent in a new suit against IBM and its SoftLayer subsidiary (6:15-cv-00906). ZitoVault accuses IBM’s cloud computing products and services, including IBM Cloud, SoftLayer, SoftLayer Cloud Servers, and Bluemix, of infringing a single patent that concerns creating and maintaining a plurality of cryptographic sessions over a computer network (6,484,257). The ‘257 patent has been asserted in only one other case to date, filed against Amazon and two of its customers (Bazaarvoice and Gearbox Software) in March 2015 (6:15-cv-00152).
