Case Summary:
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.
