Sonrai Memory Limited has filed a lawsuit in the Western District of Texas against Dell Technologies Inc. for patent infringement alleging that the defendant infringed its patents-in-suit relating to improvements in charge pump circuits for products such as laptops, desktop computers, and servers.
The plaintiff alleges that the defendants infringed on its patents-in-suit with United States Patent Nos. 6,724,241 (the ’241 patent); 6,920,527 (the ’527 patent); and 7,436,232 (the ’232 patent) covering improvements in charge pump circuits and portable memory devices with both volatile and non-volatile memory and regenerative clock repeating.
The plaintiff reportedly said that the defendant infringed its patents with its SanDisk/Toshiba 64L 3D NAND flash chips installed on Dell products including laptops, desktop computers, and servers.
According to the lawsuit, Dell’s products infringed the ’241 patent covering Variable Charge Pump Circuit with Dynamic Load which states that a charge pumps circuit for generating a charge pump voltage having minimal voltage ripples.
The plaintiff alleges that the infringed products have a pumping circuit with one or more operating stages, in this instance three stages to receive a supply voltage and generate a selected one of a plurality of pump voltages which infringed on the patents-in-suit.
The plaintiff is accusing Dell of direct, induced, and contributory infringement.
The plaintiff seeks declaratory judgment in its favor; an injunction; an award for damages, costs, and fees; pre and post-judgment interest; and other relief.
The case is ongoing.
