In May, the last open case in the litigation campaign of Ideahub, Inc.’s Pantech Corporation and Pantech Wireless, LLC, filed roughly one year ago against YulongComputer Telecommunications Scientific Company (Coolpad Technologies), was dismissed with prejudice from the Eastern District of Texas following an April notice of settlement. Now, Pantech has sued OnePlus (5:22-cv-00069) in the same district, again targeting the provision of devices that are compliant with LTE and 5G cellular networking standards, as well as those that support certain touch-based functionalities.
Last month, RPXnoted the movement of a portfolio of over 100 US patent assets from Signal Trust for Wireless Innovation—formed in 2013 by InterDigital, Inc. to “monetize a patent portfolio primarily related to 3G cellular infrastructure”—to Pantech Wireless, LLC, a Texas NPE with ties to Glocom, Inc. and Ideahub, Inc. Now several of those patents have appeared in litigation, Pantech Corporation and the Texas Pantech Wireless suing BLU Products (1:21-cv-22663) over the provision of devices, including certain S, G, and Vivo-series smartphones, that comply with LTE cellular networking standards. At issue are features such as the support for various 3GPP technical specifications and Google Cast streaming service. The Pantechs have filed the new case just as its previous suit against BLU Products has been greatly streamlined by stipulation.
Delaware plaintiff Helios Streaming, LLC (as exclusive licensee) and its Korean parent Ideahub, Inc. (as patent owner) have followed up their January case against Fandango (8:21-cv-00211) with a new suit against Comcast (NBC Universal Media, Peacock TV) (8:21-cv-00259). The two cases fall within a media streaming campaign in which the plaintiffs target “the standard for dynamic adaptive streaming delivery of MPEG media over HTTP, ISO/IEC 23009-1:2014, and subsequent versions of this standard” (MPEG-DASH). Both were filed in the Central District of California wing of the campaign, in which District Judge James V. Selna just held a claim construction hearing; a Markman hearing in the Delaware cases is currently scheduled for this May.
