VDPP LLC last sued Microsoft and Lenovo (Motorola Mobility) in December 2020, both cases filed in the Northern District of Illinois and both dismissed without prejudice in March 2021 after Central District of California Judge James V. Selna invalidated claims from three patents asserted against VIZIO for indefiniteness. However, in March 2022, the Federal Circuit reversed that ruling, remanding for further proceedings, in response to which VDPP sued Microsoft, in April 2022 in the Western District of Texas, and now Motorola Mobility (1:22-cv-03280), again in the Northern District of Illinois. The Microsoft case was dismissed earlier this month, while the new Motorola Mobility suit has been assigned to District Judge Joan Humphrey Lefkow.
