Sonraí Memory Limited has sued Kingston Technology (8:21-cv-01039) and Western Digital (8:21-cv-01040) over the provision of devices that contain “SanDisk/Toshiba 64L 3D NAND flash chips”, as well as solid state drives (SSDs) that include Silicon Motion SSD controllers (Kingston) or Marvell SSD controllers (Western Digital). These new suits expand a campaign that started in February of this year with Western District of Texas cases against Alphabet (Google), LG Electronics (LGE), and Samsung and that proceeded with separate additional suits filed against Apple, Dell, and Kioxia in April, also in West Texas. The new litigation, by contrast, has been filed in the Central District of California.

Both Realtime Data LLC (RTD) and its subsidiary Realtime Adaptive Streaming LLC (RAS) recently added cases to their respective wings of what has become one of the longest-running, widest-ranging active litigation campaigns. RTD asserted three familiar data compression patents against Facebook (1:18-cv-01373), targeting its Zstandard compression algorithm, as well as products and services “that incorporate the algorithm”. Meanwhile, RAS tagged Charter Communications (1:18-cv-01345), Comcast (1:18-cv-01446), and Cox Communications (8:18-cv-00942), asserting three equally familiar video compression patents against the companies’ respective broadcasting services, training infringement allegations—as it has in most of its cases in this campaign—on the use of the H.264 video compression to standard “to deliver HD video broadcasting products/services” to customers.

The number of defendants in the sprawling litigation campaign of Realtime Data LLC (RTD) and its subsidiary Realtime Adaptive Streaming LLC (RAS) has now topped 100, with the latter entity’s new suits against AMD (1:18-cv-01173), Intel (1:18-cv-01175), LG Electronics (LGE) (6:18-cv-00215), and Mitel Networks (1:18-cv-01177), filed last week. RAS accuses the defendants of infringement through the provision of products that support the H.264 video compression standard, including its Scalable Video Coding feature/extension (which allows a video bitstream to contain a subset bitstream that can comprise a lower-resolution or lower-quality version of the video). The accused AMD products include GPUs and APUs incorporating its Video Coding Engine; the accused Intel products, QuickSync Video implemented in Intel Core I9-8950HK, Intel Core i7-8850H, Intel Core i7-8750H, Intel Core I5- 8500B, and Intel Core i3-8300T processors; LGE, smartphones, hybrid recording DVRs, video servers, and surveillance systems; Mitel, video communications products and routers.

Last week saw a barrage of new complaints filed in the long-running campaign litigated by Realtime Data LLC (RTD) and its subsidiary Realtime Adaptive Streaming LLC (RAS). RTD asserted overlapping subsets of patents from its data compression portfolio in new cases against Cloudera (1:18-cv-00653), Huawei (6:18-cv-00182), and IBM (6:18-cv-00188). Meanwhile, RAS filed complaints asserting overlapping subsets of patents from its video compression portfolio against Alphabet (Google) (2:18-cv-03629), Avaya (1:18-cv-01046), Broadcom (1:18-cv-01048), and Wowza Media (1:18-cv-00927). With these new cases, the number of defendants in this sprawling litigation campaign now approaches 100, with the number of patents asserted holding steady at just shy of 40 and the number of petitions for inter partes review (IPR) of various of those patents topping 50.

So far in 2018, Realtime Adaptive Streaming LLC (RAS) has filed two new cases in the sprawling campaign that its parent entity, Realtime Data LLC (RTD), has been litigating since April 2008 and that it joined as a plaintiff last August. The new suits accuse Adobe (1:18-cv-10355) and Samsung (6:18-cv-00113) of infringing the same set of seven patents, five of which are drawn from a homegrown family of nine video compression patents, and the other two of which, broadly concerning similar subject matter, have been recently acquired. The accused devices include a long list of Adobe products and an even longer list of Samsung products (including EXYNOS application processors, smartphones, tablets, DVRs, Blu-ray players, cameras, and surveillance cameras) that operate in compliance with the H.264 and/or H.265 video compression standards. RAS’s latest cases bring its campaign defendant count to nearly 90.

So far in November, a new case has been added to each portion of a long-running, chaotic litigation campaign, one waged by Realtime Data LLC (RTD), the New York plaintiff involved from the campaign’s beginning, and the other waged by Realtime Adaptive Streaming LLC (RAS), a Texas subsidiary of RTD only involved in the campaign since this past August. RTD has filed suit against Fortinet (1:17-cv-01635) in the District of Delaware, asserting four data compression patents, already at issue in other cases brought by RTD, against Fortinet’s network security products Fortigate and Fortigate IPS. Meanwhile, RAS has filed suit against Polycom (1:17-cv-02692) in the District of Colorado, asserting five video compression patents, already at issue in earlier RAS cases, against Polycom’s telepresence and other video communication products that use the H.264 video compression standard. These new suits follow the cancellation by the PTAB of claims from one of the most frequently asserted RTD patents.
