After District Judge Rodney Gilstrap issued letters rogatory to effect service on the first two defendants in its campaign, Taiwanese companies Acer and MediaTek, M-Red Inc. has expanded that campaign with another Eastern District of Texas suit. The third defendant is Panasonic (2:19-cv-00251), which M-Red accuses of infringing the same three patents already in suit, as well as a new one. With the three related patents, broadly directed to measuring and/or adjusting for temperature and voltage fluctuations in an integrated circuit (IC), the NPE targets Panasonic’s provision of products that “utilize on-chip temperature sensors for power management” such as Qualcomm’s Snapdragon 602A, 820A, and or 820 systems-on-chips (SOCs), including the Ford SYNC 3 Infotainment System. As to the newly asserted patent, which is generally related to temperature testing an IC device that contains a solder ball array connection, M-Red targets the provision of certain ICs or products incorporating ICs including the Panasonic MN2WS0270, MN34120, MN34230, MN34440PL, MN34595, MW39781, and MW39783 SoCs.
