A German court has ruled in favor of Osram in its patent-infringement lawsuit against Dominant, a Malaysian LED manufacturer. The ruling concerns a group of patents covering conversion technology used in white LEDs.
The higher regional court in Karlsruhe confirmed that Dominant is illegally using or has used Osram AG technology covered by seven patents. The regional court in Mannheim had already reached the same verdict regarding three of these patents on July 2007.
Interestingly, another Malaysian company, MyLED, is planning to establish an LED manufacturing capability within the next few months. MyLED recently signed an LED-chip supply agreement with Osram.
In other patent news, the Chinese LED lighting manufacturer ATG Electronics Corp. has received multiple utility patents and a design patent for its LED products.
The utility patents cover various aspects of the products, including the dimming function, the smoothness of the light output, the internal power supply and electronic ballast for LED tubes, and built-in sensor technology for LED ceiling lights. The design patent covers mainly the thermal management technology for LED tubes.
