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.

Texas monetization firm IP Edge LLC has filed suit over another of the former Cypress Semiconductor patents received from Monterey Research, LLC in November 2020. Mallard IP LLC has accused Inspur Systems (2:21-cv-01332) and Super Micro Computer (6:21-cv-01011) of infringing the patent—generally related to a “programmable digital circuit block”—through the incorporation of DDR4 SDRAMs within their NF3120M5 and SuperServer E300-9D servers, respectively. As a formal matter, the new cases do not constitute a new campaign, as Heritage IP LLC, another apparent IP Edge plaintiff, is already litigating another patent in the same family, suing Fossil (1:21-cv-01401) and Nintendo (2:21-cv-01333) just last week.
