In April 2017, XR Communications, LLC (d/b/a Vivato) launched a litigation campaign with 11 lawsuits, each asserting the same three wireless communications patents. Quick dismissal of one of those cases left ten active in the Central District of California, the one against Ruckus Wireless becoming messy following Brocade’s sell-off of Ruckus to ARRIS in the wake of its own acquisition by Broadcom. XR Communications tried to salvage the situation by filing against ARRIS in the Los Angeles court, but District Judge Andrew J. Guilford handed down a colorful March 20, 2018 order, transferring the Ruckus Wireless case to the Northern District of California. XR Communications has responded by dismissing its Central District case against ARRIS and filing a new one (5:18-cv-02736) in the Northern District, targeting certain access points and routers sold by ARRIS, including certain of its SURFboard and Touchstone cable modems. Meanwhile, back down in Los Angeles, the court has stayed the remaining cases in light of multiple petitions filed for inter partes review (IPR) of the three patents-in-suit.
