Parity Networks LLC has added two Western District of Texas suits against Cisco (6:19-cv-00207, 6:19-cv-00209) to its network traffic management campaign. In the first case, the NPE asserts three patents for the first time, together with the only patent familiar to the litigation yet to be challenged before the Patent Trial and Appeal Board (PTAB). All four patents at issue in the second case have been previously asserted and challenged in a petition for inter partes review (IPR). Cisco’s accused products include various network hardware operating systems (Cisco IOS, Cisco IOS XR, Cisco IOS XE, and Cisco NX-OS) offering various network traffic management features as well as switches and/or routers running that software.
