Inventor’s Location Tracking Campaign One-Twos Microsoft, Through TracBeam and FineTrak

  • July 25, 2017

Dennis J. Dupray is a named inventor on each member of a 19-patent family broadly related to wireless location systems. In August 1995, Dupray formed TracBeam LLC in Colorado, assigning some of his patent assets to that entity and launching a litigation campaign over some of them in 2011. TracBeam has kept that campaign alive by filing a new case against Microsoft (6:17-cv-00426), targeting a host of Microsoft applications and services with five Dupray patents (7,274,332; 7,298,327; 7,525,484; 7,764,231; 9,060,341). On the same day, FineTrak, LLC, an entity that Dupray created in Florida in July 2015, kicked off another campaign, accusing the same set of Microsoft (6:17-cv-00427) products, but over a different Dupray patent (8,994,591). Dupray has assigned others of his patents to a third entity, Mobile Maven LLC, which has yet to file suit.
