Nichia Enforces Foundational Filament LED Patent in Delaware Against LED Lighting Manufacturer

On July 26, 2019, Nichia Corporation ("Nichia") filed a patent infringement lawsuit in the United States District Court for the District of Delaware against Global Value Lighting, LLC (“GVL”), a US-based manufacturer of LED lighting products.

In its lawsuit, Nichia has asserted a filament LED patent, U.S. Patent No. 9,752,734, as well as 5 patents (U.S. Patent Nos. 6,337,493, 6,870,191, 7,345,297, 7,804,101 and 9,324,791) that cover the design of LED chips.

Nichia filed its application for U.S. Patent No. 9,752,734 in 2005, following research that led to groundbreaking innovations in filament LED technology. Nichia’s record of innovation in many areas of LED manufacture and design, including in the filament LED field, is one of the reasons why Nichia has maintained its position as the world’s leading LED company.

With the increasing popularity of filament LED products in the United States, major manufacturers of lighting products, such as GVL, have entered into the filament lighting market without proper regard for the Nichia’s inventions. Thus, Nichia has initiated enforcement of its foundational filament LED patent to protect its valuable technology and to maintain fair competition in the marketplace.

Nichia seeks to protect its patents and other intellectual property rights and takes action against alleged infringers in any country where appropriate and necessary.
