Two NPEs associated with Ortiz & Lopez, PLLC (d/b/a OL PATENTS)—Mesa Digital LLC and Ortiz & Associates Consulting, LLC (OAC)—have continued their recent practice of filing suits in pairs, Mesa Digital suing Acer (3:20-cv-02337) in the Northern District of California and OAC hitting Hisense (1:20-cv-02193) in the Northern District of Illinois. A different patent from the same family is asserted in each new complaint, Mesa Digital’s generally related to a “multimedia” mobile device and OAC’s, to the transmission of video data from a wireless device to a “data rendering device”. Acer joins recent defendants HTC (sued in October 2019) and Zebra Technologies (in December 2019) in the mobile devices wing of this campaign; Hisense joins Panasonic (also in October 2019) and Microsoft (also in December 2019) in the video transmission wing. Issues surrounding service of complaints continue to plague the more recent suits brought by Mesa Digital alone in this long-running campaign.
