NTP Brings Suit Against All Four National Carriers

NTP has brought suit against the four nationwide US carriers for patent infringement. The suits allege that email services offered by the carriers violate NTP's mobile email patents. After a long trial, RIM settled with NTP earlier this year, paying over $600 million to license NTP's patents. Though their Blackberry offerings are covered by this agreement, each carrier offers its own push email services as well, such as T-Mobile's My Email. NTP is seeking damages and injunctions against the carriers for offering these services.
