Early in January, LED Apogee LLC sued Analog Devices and Microchip Technology in separate Eastern District of Texas complaints, as well as NXP Semiconductors (NXP USA), in the Western District of Texas. Four days later, the plaintiff hit MediaTek (6:24-cv-00023) and STMicro (6:24-cv-00027), both also in West Texas, both also targeted over the provision of LED drivers (the RT4539 and STLED524, respectively) with a single patent generally related to “driving a light emitting diode coupled to an output of a current mirror”.
