Verizon Wireless was accused by Dynamic Transmission Technologies of patent infringement, claiming that it has violated their patent relating to wireless data communication. The patent in question was US6052408, entitled ‘Cellular communication system with dynamically modified data transmission parameters’, which was legally issued to Michael L. Trompower, Paul F. Struhsaker on Apr 18, 2000 and expiring[i] by Sep 16, 2015. The patent is currently assigned[ii] to Dynamic Transmission Technologies (source: MaxVal’s Assignment Database).
The patent describes a process for improving the performance of a cellular communication system using direct sequence spread spectrum techniques. According to the complaint filed, defendant designs, manufactures, and sells wide and local area wireless access technology and services, including mobile telephone cellular services and mobile device wireless communication access services, which infringe the ’408 patent.
Dynamic Transmission Technologies said ‘Defendant’s infringing technology and services include Verizon’s LTE and EVDO enhanced mobile networks, and devices sold for use with the Verizon mobile networks, including, the HTC Droid DNA, LG Lucid 2, and other mobile communications devices. It asked the Court for judgment in favor declaring defendant has infringed the patent-in-suit, damages to compensate the past infringement, permanent enjoinment from using their patent, interest, costs and other relief the Court may deem just and proper.
Plaintiff Dynamic Transmission filed a notice of voluntary dismissal of the case, pursuant to which the Court granted dismissal without prejudice, thereby closing the case.
