Virtual Immersion Technologies LLC (VIT) has fired off another round of complaints in its sole litigation campaign, begun in 2016, over a single patent generally related to virtual reality entertainment systems. The Equitable IP Corporation plaintiff has sued Balfour Beatty (6:20-cv-01048), Black and Veatch (6:20-cv-01049), and Robert Bosch (Bosch Rexroth) (6:20-cv-01048) over the use and/or provision of “virtual and augmented reality technologies and services” in multiple contexts, including marketing and training. Seven of the nine cases from the last round, filed in July, have already been dismissed, with extensions of the service deadline granted in the remaining two suits, against DPR Construction and Schneider Electric.
