Sisvel International S.A. (d/b/a Sisvel Group) has added another District of Delaware case, this one against Dell (1:19-cv-01247), to the litigation campaign that it began there with early June suits against AnyDATA, BLU Products, Cradlepoint, Honeywell, Verifone, and Xirgo Technologies. Those cases saw five former Nokia patents asserted, each of which Dell is accused of infringing as well, but the new suit adds accusations as to seven former BlackBerry patents. At issue is Dell’s provision of the 5510 Mobile Broadband Wireless Cellular Modem, Latitude 5000 and 7000 Series computers, the Precision 3520 Workstation laptop, and the Precision 7000 Series computers.
