In October 2022, DivX, LLC filed two complaints against Amazon and VIZIO, one before the International Trade Commission (ITC) and the other in the Eastern District of Virginia. The latter was stayed in customary fashion to await the outcome of the ITC investigation, which resulted in a May 2024 finding in favor of Amazon (VIZIO having been terminated from the ITC investigation along the way), based on, among other things, noninfringement. Last week, DivX voluntarily dismissed that parallel stayed case, doing so on the same day that it filed a new complaint in the same district against Amazon (3:24-cv-00818), this one asserting six different patents.

Attestwave LLC has added a new round of cases to the litigation campaign it began back in October 2022, suing BlackBerry (2:24-cv-00929), Cortado Mobile Solutions (2:24-cv-00928), Honeywell (2:24-cv-00926), Sophos (2:24-cv-00930), and SOTI (2:24-cv-00927). The plaintiff asserts a patent new to the litigation but related to the prior patent-in-suit, the patent broadly directed to “assuring proper execution of a software computer program” through tamper detection and validation. Targeted in the set of Eastern District of Texas complaints is the provision of application and/or device management software, including enterprise mobility management (EMM), mobile device management (MDM), and unified endpoint management (UEM) solutions. At issue is the use of device attestation for “verifying device and app integrity”.

Entropic Communications, LLC has filed separate Eastern District of Texas cases against Ubee Interactive (2:24-cv-00911) and Vantiva (f/k/a Technicolor) (2:24-cv-00912), targeting the provision of cable modems and gateways, with Vantiva further targeted over television set-top boxes, that “include or are based on the Broadcom BCM3390, BCM33843, or BCM3384 [systems-on-chip (SoCs)]”. The new cases have been assigned to District Judge Robert W. Schroeder III, but Chief Judge Rodney Gilstrap presided over the earlier litigation in this district from Entropic, against Charter Communications. There, most recently, briefing has completed in an appeal that the Electronic Frontier Foundation (EFF) filed after the district court denial of its motion to intervene, following settlement, to seek the unsealing of the parties’ briefing (and evidence) regarding “a nationally important, precedent-setting case-dispositive defense”.

Earlier this year, RPX noted the transfer of eight US patents from DCX US Agility Platform LLC, a subsidiary of DXC Technology, to VideoLabs, Inc., which is in active litigation over earlier-collected patents, from multiple operating companies. Last month, portfolios of additional patents moving to VideoLabs appeared in publicly available USPTO records, from three new sources: OLogN Technologies AG (in May 2024), PRJ Holding Company LLC (in July), and ZING Communications Inc. (in July as well). Meanwhile, VideoLabs and its subsidiary VL Collective IP, LLC have sued Hisense, together with myriad subsidiaries (2:24-cv-00904), over the provision of streaming products (e.g., dongles, projectors, set-top boxes, and TVs) that support the H.264 compression standard and/or are compatible with High-Bandwidth Digital Content Protection (HDCP), including certain Roku-series software products.

Last week, Genghiscomm Holdings, LLC filed a second complaint against Samsung (2:24-cv-00901) in the Eastern District of Texas. Asserted is a single patent from the same family to which the eight patents already in suit belong, this one broadly directed to discrete Fourier transform-spread orthogonal frequency division multiplexing (DFT-spread OFDM) used in LTE uplink. Samsung has answered the complaint in the prior suit, in which the court has set a schedule and moved the matter into discovery.

In a new Southern District of Florida complaint, T5.2 Ltd. has accused Cloud Software Group (Citrix Systems) (0:24-cv-62093) of infringing eight patents through the provision of various “Hypervisor, virtual application and virtual desktop infrastructure products” that allegedly offer certain “compression assistance, processing, and/or GPU-sharing functionality”. The inventor-controlled plaintiff pleads that T5 Labs, a British entity also run by Graham Clemie, owns the asserted patents and that it is “the exclusive licensee with all right, title, and interest in and to” them. T5.2 is the third plaintiff to sue as an exclusive licensee of patents held by T5 Labs.

Stingray IP Solutions, LLC has filed an Eastern District of Texas case against HP Enterprise (HPE) (2:24-cv-00868) that targets the provision of “networking, IoT, and security solutions, products, components, software, services, and processes related to same that generally connect to other devices in a network or other networks using a wireless protocol, such as ZigBee and/or Wi-Fi”. The Acacia Research Corporation plaintiff describes the three asserted patents as covering “various aspects of monitoring, detecting intrusions, and encrypting and decrypting wireless communications networks”. The exemplary accused products include access points, controllers, gateways, and related accessories and software products.

Sandpiper CDN, LLC has filed an Eastern District of Texas suit against Comcast (2:24-cv-00886) over the provision of its products and services that use “Apache Traffic Control and any of Comcast’s bespoke CDN architecture or solutions”. Asserted are five patents, generally related to various aspects of content delivery networks, that the plaintiff received from Level 3 Communications in a series of 2024 transactions, only one of which is in suit against Alphabet (Google), in a Central District of California suit filed this past May. Google has knocked two of those patents out of the case with an Alice motion.

Apparent Blue Wave IP plaintiff EDGE NETWORKING SYSYEMS LLC (ENS), filing as “Edge Networking Systems LLC”, has followed up its February case against Microsoft, in the Western District of Texas, with an Eastern District of Texas suit against Amazon (2:24-cv-00887) over the same three networking patents. Infringement allegations target the provision of the Amazon Elastic Kubernetes Service (“EKS”) Web Services and products incorporating thereof (i.e., Amazon Aurora, Amazon SageMaker, and Industrial Data Fabric). A motion to dismiss the Microsoft case is fully briefed before District Judge David A. Ezra.

After suing Toyota in early October, AutoConnect Holdings LLC has filed a complaint against General Motors (2:24-cv-00877), also in the Eastern District of Texas, asserting ten patents that overlap with those already in suit. Again at issue is the provision of a wide array of automobiles, vehicle systems (e.g., in-vehicle multimedia systems), mobile apps, and related hardware and software components, with a focus on features like the support for Apple’s CarPlay and Google’s Android Auto platforms, security measures, user device profiles, and more.
