Inventor-controlled COOLTvNetwork.com, Inc. has initiated its first litigation campaign, suing Blackboard (1:19-cv-00291), Facebook (1:19-cv-00292), IBM (1:19-cv-00293), Kaltura (1:19-cv-00294), Limelight Networks (1:19-cv-00295), Microsoft (1:19-cv-00296), and Ooyala (1:19-cv-00297) in the District of Delaware. In each complaint, the plaintiff asserts a single patent generally related to a “multifunctional hot spot”, accusing the defendants of infringement through the provision of interactive features within online video delivery or streaming services. For example, COOLTvNETWORK.com targets Facebook over, among other things, click-through links in video ads, as well as features related to buying the advertised product or service.
