Its separate 2021 cases against Acer and HP now closed, Shamrock Innovations, LLC has filed suit against Lenovo (5:22-cv-00102) over the same two patents, generally related to a serial link connecting two computing modules. The Eastern District of North Carolina complaint again targets the provision of computers that include a Serial ATA interface. Shamrock received the asserted patents from Intellectual Ventures LLC (IV) in an assignment dated in December 2017, with public records suggesting a more complicated connection between IV and the plaintiff.
