The United States District Court, Eastern District of Texas is becoming a hot bed for patent infringement suits. This is because the judge in the court has a history of siding with the patent holders in infringement suits and has awarded verdicts against Nintendo and other large companies already.
TiVo is trying its luck in the courtroom with a new patent infringement suit against AT&T and Verizon over patents relating to DVR technologies TiVo holds. The patents in question are Nos. 6,233,389 B1 (“Multimedia Time Warping System”), 7,529,465 B2 (“System for Time Shifting Multimedia Content Streams”), and 7,493,015 B1 (“Automatic Playback Overshoot Correction System”).
