Innovative Display Technologies LLC v. T-Mobile US, Inc.

This patent infringement litigation, Innovative Display Technologies LLC v. T-Mobile US, Inc., centers on alleged infringement related to display and backlight technologies in mobile devices. The case was filed in the U.S. District Court for the Eastern District of Texas, a venue historically favored by patent plaintiffs.

The plaintiff, Innovative Display Technologies LLC, is identified as a patent assertion entity (PAE) or "patent troll," closely associated with prolific inventor and litigant Leigh M. Rothschild. Rothschild-affiliated entities, including Display Technologies LLC, are known for extensive patent litigation campaigns across a wide range of technologies. The defendant, T-Mobile US, Inc., is a major mobile network operator in the United States. The accused products are T-Mobile's mobile devices, such as smartphones, which incorporate LCD and backlight technologies.

The specific patent asserted in this case is U.S. Patent 7,300,194. However, a detailed one-line technical sketch for a granted U.S. patent with this exact number could not be definitively identified through publicly available patent search databases at the USPTO or Google Patents. This suggests the patent number provided may be subject to a typo or refers to a type of patent not immediately discoverable through standard searches for utility patents.

The case is proceeding in the U.S. District Court for the Eastern District of Texas, a venue long considered a "rocket docket" and a popular forum for patent owners due to its reputation for fast trials and plaintiff-friendly procedures. While the specific division and assigned judge for case 2:14-cv-00723 are not readily ascertainable through general web search, cases in this district are often heard in divisions like Marshall or Tyler. The litigation is notable due to the plaintiff's pattern as a patent assertion entity, particularly its affiliation with Leigh M. Rothschild, who has been involved in numerous patent disputes. Recently, a jury in the U.S. District Court for the Western District of Washington found that Rothschild and associated entities, including Display Technologies LLC, had breached a licensing agreement and violated Washington's Patent Troll Prevention and Consumer Protection Acts in a separate case against Valve Corporation, highlighting the plaintiff's aggressive assertion strategies.

This case, Innovative Display Technologies LLC v. T-Mobile US, Inc., Case No. 2:14-cv-00723, filed in the U.S. District Court for the Eastern District of Texas, concerns alleged infringement of U.S. Patent No. 7,300,194. The plaintiff, Innovative Display Technologies LLC (IDT), is a patent assertion entity, with Acacia Research Group LLC and Acacia Research Corporation identified as its real parties-in-interest.
