Amazon Notches Win Against DivX at the ITC
In Case You Missed It
Administrative Law Judge (ALJ) Bryan F. Moore at the International Trade Commission (ITC) has posted a notice indicating that he has found no Section 337 violation “in the importation into the United States and the sale within the United States after importation of certain video processing devices and components thereof based on” the alleged infringement by Amazon of four patents held by DivX, LLC. The initial determination remains confidential. VIZIO, also a respondent in the same ITC action, was terminated from the investigation last September. A status report is due to Eastern District of Virginia Judge David J. Novak in mid-June in a parallel case that has been stayed to await the ITC outcome. Meanwhile, DivX district court cases are active again against Netflix and Realtek Semiconductor.

Second Rothschild Plaintiff Sues SiriusXM
New Patent Litigation
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.
