A week after Blue Spike LLC’s case against Audible Magic and 20 of its customers was dismissed, the NPE turned its attention to its newest litigation campaign, suing ZTE (6:16-cv-01020) over a group of six patents generally related to packet watermarking (7,287,275; 8,224,705; 8,473,746; 8,706,570; RE44,222; RE44,307). The complaint filed on July 15 accuses ZTE of infringement through provision of routers and switches. This case is the second filed in a campaign that Blue Spike initiated in February of this year; the first case, lodged against Huawei (6:16-cv-00048), is active in initial pleadings.
