AT&T (2:24-cv-00588) is the latest defendant to be added to the sole litigation campaign of Quantum Technology Innovations, LLC (QTI), launched in April 2022. In the new Eastern District of Complaint, AT&T is accused of infringing a single patent—generally related to a server running a computer program for distributing content over a network—through the provision of the AT&T Content Delivery Network (CDN). At issue is the alleged use of a “geographically distributed network of edge servers or Points of Presence (POPs) to provide immediate content access for the end users”.

So far this month, Quantum Technology Innovations, LLC (QTI)—a plaintiff associated with monetization figure Leigh M. Rothschild—has expanded its sole litigation campaign with suits against EchoStar (DISH Network) (2:24-cv-00420) in the Eastern District of Texas and AMC Networks (1:24-cv-04745), BroadwayHD (1:24-cv-04679), and Warner Bros. Discovery (1:24-cv-04750) in the Southern District of New York. At issue across each complaint is a single patent generally related to a server running a computer program for distributing content over a network. The defendants are accused of infringement through the provision of their respective streaming services and related apps (Sling TV, AMC+, BroadwayHD, and Max, respectively). At issue are features such as streaming content at various quality levels, live TV streaming, servers and content delivery networks (CDNs), and streaming analytics.

The bulk of the Eastern District of Texas complaint that Quantum Technology Innovations, LLC just filed against Liberty Media (SiriusXM) (2:24-cv-00246) is devoted to recounting the prosecution history of the sole patent-in-suit and to pleading defensively against an Alice attack. The intensity of that focus is perhaps motivated by the SiriusXM motion challenging the patents asserted against it this past December—by Display Technologies, LLC, which, like Quantum, is a plaintiff associated with Leigh M. Rothschild—as patent-ineligibly drawn to the abstract idea of “transferring a digital media file”. There, SiriusXM cites a prior court order characterizing Display’s “goal”: to pursue a “’nuisance-value’ settlement” through a “ransom” that SiriusXM does not wish to pay.

Valve has filed a second amended complaint in the Western District of Washington case (2:23-cv-01016) begun last July against Leigh M. Rothschild and three associated entities Display Technologies, LLC; Patent Asset Management, LLC; and Rothschild Broadcast Distribution Systems, LLC (RBDS), together with Rothschild counsel Meyler Legal, PLLC and its principal Samuel Meyler. The defendants have refiled a motion to dismiss the complaint in which they argue that Valve is “attempting to make ‘a mountain out of a mole hill’ by characterizing a simple clerical error as some sort of legal malfeasance” under the state’s “Patent Troll Protection Act”. Meanwhile, venue challenges in Eastern District of Texas cases filed this past September by three other Rothschild plaintiffs—Quantum Technology Innovations, LLC; Social Positioning Input Systems, LLC (SPIS); and Symbology Innovations, LLC—are ripening.
