Seoul Semiconductor Files Patent Infringement Lawsuit against Amazon in the European Unified Patent Court

Seoul Semiconductor Co filed a patent infringement lawsuit in the European Unified Patent Court against Amazon (Amazon Services Europe), the world's largest distribution company, seeking an injunction against the sale of infringing products.

SSC and its affiliates have obtained 15 permanent injunctions for patent infringement against various manufacturers and distributors in the past five years from the U.S., Germany, France, and Netherlands courts. Filing lawsuits in individual countries, however, was a less efficient way to enforce patents against infringing products.

The European Unified Patent Court, which was established in June 2023, has comprehensive jurisdiction over European patent litigation. Injunction and damages orders for patent infringement from the Unified Patent Court can take effect simultaneously in 17 European countries, including Germany, France, and Italy. Consequently, SSC can now prevent the distribution of infringing products throughout Europe with a single lawsuit.

Among the over 18,000 patents held by SSC, the asserted patent in this lawsuit relates to a revolutionary technology that freely adjusts the brightness and color of LED lighting products over time. This solution technology is widely used in smart lighting products and color-tunable lighting. Another asserted patent relates to heat dissipation in LED packages, a crucial technology widely used in automotive lighting where heat dissipation is critical.
