Seoul Viosys Obtains Permanent Injunction Against UV LED Products That Infringe Violeds Patented Technology

Seoul Viosys (“SVC”) (KOSDAQ: 092190), a subsidiary of Seoul Semiconductor Co., Ltd., announced that the United States District Court for the Middle District of Florida issued a permanent injunction against Namsung America, Inc. (“Namsung”). Namsung sold home electronics incorporating UV LEDs manufactured and supplied by SL Vionics Co., Ltd. (previously known as Semicon Light).

Prior to the lawsuit, Namsung ignored repeated notices of patent infringement from SVC. Since 2020, SVC has been requesting that companies stop selling SL Vionics’ LED products. SVC believes that SL Vionics’ LED products infringe SVC’s proprietary Violeds technology, which SVC invented and has been utilizing to produce its UV LED products. When Namsung continued selling products after notice from SVC, SVC filed this lawsuit, which asserted infringement of eleven (11) patents.

The Court’s permanent injunction order applies to any colorable variations of the infringing products, as well as any parties who are in active concert or participation with making or selling such products.

SVC’s CEO, Young-joo Lee, said, “There are companies that seek to increase their profits by using other companies’ patented technology. This is not only immoral, but it seeks to cheat inventors everywhere who have invested and believed in their ideas.”

In order to protect its hard-earned technology and promote a fair marketplace, SVC actively pursues enforcement against suspected infringing UV LED products all over the world. As an example, SVC recently brought a search and seizure of suspected infringing products against FNAC Darty Group, a large European retailer, and subsequently filed a patent infringement lawsuit in France. SVC also filed a patent infringement lawsuit against a European distribution company in the Netherlands, seeking a preliminary injunction against its UV LED products.
