Dunti Network Technologies, LLC v. Cisco Systems, Inc.

A Texas NPE formed this past June, Dunti Network Technologies, LLC (DNT), has begun asserting patents from a ten-patent network architecture portfolio issuing to named inventor Rupaka Mahalingaiah. DNT has hit Arista Networks (2:16-cv-01028), Broadcom (2:16-cv-1031), Cisco (2:16-cv-01026), Extreme Networks (2:16-cv-01034), Hewlett Packard Enterprise (HP) (2:16-cv-01013), Huawei (2:16-cv-01021), Intel (2:16-cv-01035), and Juniper Networks (2:16-cv-01036) over the past week, accusing the defendants of infringement through the sale of certain switches and associated network solutions (e.g. HP FlexFabric data center switches and HP Intelligent Management Center Enterprise Software Platform, Huawei CE series data center switches and Huawei Next-Generation Network Operating System Versatile Routing Platform, etc.). The new complaints lay out a long history of “pioneering” development work in “real-time computing” by Mahalingaiah, emphasized as a “foreign-born, female, computer engineer” defying odds and overcoming “large-scale industry pushback and skepticism”, all leading to the litigation over the seven patents (6,587,462; 6,643,286; 6,754,214; 6,788,701; 6,804,235; 6,912,196; 7,778,259) now in suit.
