Eridanus Technologies, Inc. (ETI) received five patents from STMicroelectronics back in February 2015, but the Wi-LAN Inc. (WiLAN) subsidiary filed what appears to be its first suit from that received portfolio just this past week. ETI accuses AMD (1:23-cv-01036) of infringing two of those patents—one generally related to reducing current leakage in logic devices; the other, to managing power supply to a system-on-chip (SoC)—through the provision of various computer processors (i.e., APUs and CPUs). The case comes after big changes were announced at WiLAN earlier this summer.
