Defendant
4 cases as defendant.
Delaware Display Group LLC (DDG) is a privately held company primarily engaged in patent assertion. Formed on December 20, 2013, the company appears to operate as a Non-Practicing Entity (NPE) or Patent Assertion Entity, with no public information available regarding its operational headquarters, employee count, or revenue.
Delaware Display Group LLC does not manufacture products or offer services. Instead, its business model involves asserting intellectual property rights. The company's asserted patent portfolio includes U.S. Patent Nos. 7,434,974, 7,537,370, 8,215,816, and 7,914,196, which relate to "general light emitting panel assembly configuration technology" and "backlight units used in liquid crystal displays." These patents were acquired, with Innovative Display Technologies LLC (IDT) receiving assignments from Acacia Research Group LLC, and IDT subsequently assigning at least one patent to DDG.
The company's litigation posture is that of a patent plaintiff, having initiated all six tracked cases and being a defendant in zero. This aligns with the profile of an NPE. Cases were filed in both the U.S. District Court for the District of Delaware and the U.S. District Court for the Eastern District of Texas, venues frequently utilized for patent litigation.
Notable litigation includes multiple patent infringement lawsuits filed on December 31, 2013, by Delaware Display Group LLC and Innovative Display Technologies LLC. These suits targeted various technology companies, including Amazon.com Inc., LG Electronics Inc., VIZIO Inc., HTC Corporation, Lenovo Group Ltd., Pantech Co., Ltd., and Sony Corporation, concerning display technology. Some of these cases, such as those against Amazon, HTC, and Sony, were later dismissed by agreement.
