Thus far in May, inventor Lauri Valjakka has filed suit against Cox (6:22-cv-00497), Charter Communications (6:22-cv-00491), Comcast (6:22-cv-00493), Meta Platforms (6:22-cv-00495), and Zoom (6:22-cv-00496), each in the Western District of Texas. The two patents-in-suit, asserted in overlapping sets, generally relate to transferring data over a network and providing access to restricted content to a user through a digital rights management (DRM) key, with the defendants accused of infringement through the provision of various services and related products: Cox, through the Contour streaming app; Charter, the Spectrum-branded cable, TV, Internet, and phone services; Comcast, the Xfinity-branded cable TV, Internet, and phone services; Meta, the Facebook social media platform; and Zoom, the Zoom communications platform. At issue is the use of and support for certain features related to content retrieval, such as DRM systems and content delivery networks (CDNs).
