Delaware Display Group LLC et al v. Sony Corporation et al DC

New Acacia subsidiary Delaware Display Group (DDG), along with co-plaintiff Innovative Display Technologies (IDT), filed its first seven litigations to close out 2013. IDT, another Acacia subsidiary, began its litigation campaign in June 2013 asserting a group of seven patents related to light emitting panel assemblies used in LCDs (6,755,547; 7,300,194; 7,384,177; 7,404,660; 7,434,974; 7,537,370; 8,215,816). The new suits are closely related to those previous filings, asserting the same seven patents along with an eighth patent, owned by DDG, that relates to a backlight system (7,914,196). Defendants Amazon, HTC, Lenovo, LG, Pantech, Sony, and VIZIO all make products using displays that are alleged to infringe the patents-in-suit, including laptops, smartphones, and tablets. The litigated patents were previously owned by Rambus and transferred to Acacia in March 2013. The seven previously asserted patents are owned by IDT but DDG owns the ‘196 patent, according to the complaints. 12/31, District of Delaware, 1:13cv02106, 1:13cv02107, 1:13cv02108, 1:13cv02109, 1:13cv02110, 1:13cv02111, 1:13cv02112
