Virtual Immersion Technologies LLC, an entity under the apparent control of Equitable IP Corporation, has filed another round of Delaware suits in its campaign litigating a single patent generally related to virtual reality entertainment systems. The newest defendants are 20^th Century Fox (1:17-cv-01539), Caterpillar (1:17-cv-01540), Deere & Company (1:17-cv-01541), and Ford (1:17-cv-01542). The NPE’s complaints again accuse each defendant of infringement through use of “an interactive, real time virtual reality system”, providing links to various webpages (some of them appearing to be broken) that purport to demonstrate the each defendant has created a virtual reality experience (e.g., the Ford complaint containing a URL for an online video advertisement of Ford’s purported use of Facebook’s Oculus VR headset) or filmed in 3D (e.g., the 20^th Century Fox complaint containing URLs announcing the 3D/Simulcam filming of an X-Men movie).
