The United States District Court in the Eastern Division of Texas is becoming a very common place for major corporations to file patent infringement suits against other companies. The glut of suits filed here is due to the judge's previous pro-patent holder rulings.

TiVo has announced that it has filed a patent infringement suit against AT&T and Verizon in the court alleging patent infringement on DVR technology. The suit centers on TiVo patents 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").

TiVo says that it is seeking damages for past infringement and a permanent injunction on the products that are infringing on the patents. Going by the judge's past rulings, TiVo has a very good chance of winning this legal battle.
