Orthosie Systems, LLC, a Texas-based NPE controlled by Daniel F. Perez, added a round of cases to its fleet tracking campaign on the last day of 2016, accusing over a dozen companies—DPL Telematics, Fleet Daddy, iTrack America, Kore Wireless Group, M&G Fleet Solutions, Merchants Fleet Management, Pedigree Technologies, Quartix, RareStep, Sky Patrol, Spireon, Synovia Solutions, Track Star, and Track What Matters—in separate complaints of infringing a single patent (7,430,471). The ‘471 patent generally relates to vehicle monitoring, and the accused products are the defendants’ hardware and software systems for tracking the locations of vehicles using GPS. This round of cases follows nearly a dozen filed against other fleet tracking companies in November and earlier in December.
