Blue Spike Expands Its Long-Running Digital Watermarking Campaign and Kicks off a New One, Too
Two new cases filed against The Nielsen Company (6:16-cv-00042) and Huawei (6:16-cv-00048) this week introduced 15 Blue Spike LLC patents not previously seen in litigation. The suit against Nielsen, filed on February 5, involves ten related patents (5,889,868; 7,770,017; 7,877,609; 7,913,087; 7,953,981; 8,121,343; 8,161,286; 8,175,330; 8,225,099; 8,307,213), only one of which (the ‘868 patent) has been previously asserted, in Blue Spike’s expansive digital watermarking campaign. The complaint accuses Nielsen of infringing the patents-in-suit through technologies that encode watermarks within audio content. Blue Spike’s complaint against Huawei, lodged on February 10, accuses the company’s routers of infringing six related patents that generally concern packet watermarking (7,287,275; 8,224,705; 8,473,746; 8,706,570; RE44,222; RE44,307).
