Heritage IP LLC and Mallard IP LLC, both plaintiffs apparently associated with Texas monetization firm IP Edge LLC, filed suits at the end of July, continuing their joint campaign over former Cypress Semiconductor patents. Heritage IP sued Rand McNally (RM Acquisition) (1:22-cv-01019) and ZiLOG (1:22-cv-01020) over the provision of devices that incorporate certain ARM Cortex M0-based microcontrollers with dynamic power management capabilities, including logging devices and microcontrollers, respectively. Mallard IP hit Advantech (1:22-cv-03959) over the provision of the DS-082 Player and Fujitsu (2:22-cv-00289) over the provision of the PRIMERGY GX2460 server, each of which incorporates DDR4 SDRAM.
