Contemporary Display LLC, an affiliate of monetization firm IP Valuation Partners LLC (d/b/a IPVal), has added cases filed against Cox Communications (1:19-cv-00224) and Verizon (1:19-cv-00225) to the litigation campaign that it began last April. The NPE asserts two patents familiar to the campaign while debuting two in litigation for the first time, all of them acquired from Intellectual Ventures LLC (IV) in an August 2017 transfer of five families of disparate origins. Cox is alleged to infringe through the provision of certain DVRs (while an apparently misfiled document on PACER has made the exact allegations against Verizon unclear); the patents generally relate to an adapter for a video monitor, an on-screen system for managing the inputs to a television, and a device switching between “sessions”.
