Panther Innovations LLC, an NPE with ties to several other litigating plaintiffs, has launched a second litigation campaign from a portfolio of patents received from Ascentive LLC. The NPE asserts two patents, broadly directed to optimizing “network configuration settings”, against Microsoft (6:20-cv-01071) in the Western District of Texas. Microsoft is accused of infringement through the provision of certain network optimization features—TCP-auto-tune, Congestion Provider, and Scaling Heuristics functionalities—incorporated in its Windows Vista, 7, 8, and 10 operating systems.
