This past January Redstone Logics, LLC sued MediaTek and NXP Semiconductors in a pair of Western District of Texas complaints. Now, the Texas plaintiff has added a case against Qualcomm (7:24-cv-00231), asserting the same patent already in suit, a patent generally related to a multicore processor with two set of processor cores where each has its own supply voltage and an independent PLL (“phase-locked loop”) clock signal. Infringement allegations target “products comprising one or more SoC each comprising two or more sets of processors implementing or based on the DynamIQ Shared Unit architecture (e.g., ARMv8.2, ARMv9, ARMv9.2, and successors) or big.LITTLE architecture, including without limitation the Snapdragon 8 Gen 2 and the Snapdragon 835 Mobile Platform”.

The deadline for Samsung to respond to the October 2023 complaint that Redstone Logics, LLC filed against it in the Eastern District of Texas has been pushed into early February. In the meantime, Redstone has filed two new cases, one against each of MediaTek (7:24-cv-00029) and NXP Semiconductors (7:24-cv-00028), both in the Western District of Texas. Asserted in each complaint is one of the two patents already in suit and is generally related to a multicore processor with two set of processor cores where each has its own supply voltage and an independent PLL (“phase-locked loop”) clock signal.

Redstone Logics, LLC has filed its first lawsuit, accusing Samsung (2:23-cv-00485) of infringing two patents, one generally related to a multicore processor with two set of processor cores where each has its own supply voltage and an independent PLL (“phase-locked loop”) clock signal and the other broadly directed to a thermal conduction assembly for use with an electronic circuit. The Bedrock IP Co., Ltd. plaintiff targets the provision of smartphones that contain multiprocessor systems-on-chip (SoCs) and/or incorporate certain heat management components.

Harris Corporation merged with L3 Technologies in 2019 to form L3Harris, since which time the company has divested patents to, among others, Acacia Research Corporation; several plaintiffs associated with Atlantic IP Services Limited; and at least one NPE tied to IPValuation Partners, LLC (IPVal). Earlier this month, another such assignment was executed, this time with L3 handing patents to a Texas entity with a familiar nomenclature.
