QoS IP, LLC filed a second lawsuit in its sole litigation campaign, this time against Huawei (6:15-cv-00880). As in a complaint filed earlier this month against Alcatel-Lucent (6:15-cv-00860), QoS asserts a single patent (7,385,982) generally related to quality-of-service capabilities within Fibre Channel networks. It accuses Huawei of infringement through the sale of switches that support Fibre Channel over Ethernet.
