Second Rothschild Plaintiff Sues SiriusXM

April 20, 2024

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.
