In December 2018, Irish entity Solas OLED Limited augmented its sizeable portfolio of patents, received from Casio in April 2016, with an additional set of assets received from Microchip Technology (Atmel) and one additional patent received from the University of Stuttgart. The patents generally relate to various aspects of display panels, and Solas OLED began asserting them in litigation by suing LG Display, LG Electronics (LGE), and Sony in the Western District of Texas, later adding cases against Samsung (in the Eastern District of Texas) and Alphabet (Google) and Dell (back in the Western District of Texas). With subsequent amendments to its early complaints and with a new case filed in the Western District against Apple (6:19-cv-00537), Solas OLED has now brought all of this litigation into a single display panel campaign.
