A German court ordered a permanent injunction and recall of an Everlight Electronics LED product for infringing on a Seoul Semiconductor patent.
The decision comes out of a lawsuit brought by Seoul Semiconductor against Mouser Electronics, which is based in Texas and distributes the LED product in Germany. The product includes patented reflector technology and is labeled a 2835 LED package. It measures 2.8 mm x 3.5 mm.
The District Court of Dusseldorf issued a permanent injunction against sales of the product and ordered Mouser to recall the LED product sold after February 2017 from commercial customers.
The patented technology is a Multi-Wavelength Insulation Reflector which is used to improve light reflected from an LED structure. A light reflection structure is attached to an LED chip to ensure durability and efficiency. It is widely used in mid-power LED products, according to Seoul Semiconductor, and is used in lighting and backlighting for mobile phones and autos.
In a related matter, Seoul won a permanent injunction against Everlight’s high power LED product in December 2018. A recall was issued for those products sold after July 2012 from commercial customers.
