Osram accuses Dominant over LED patent
Osram Opto Semiconductors, of Regensburg, Germany has accused Dominant Semiconductors, a Malaysian manufacturer of LEDs, of patent infringement.
The complaint, filed with the United States international trade commission, comprises two basic technologies.
The first group covers technology that enables LEDs to emit white light from a single semiconductor chip. Applications for these LEDs include backlighting for cell phones and automobile dashboards.
The second group of patents concerns technology for electrical connection structures used in LEDs, including high-power LEDs for automobile lighting applications, such as interior lighting and rear combination light systems.
Osram has requested an order to prevent a wide range of Dominant s LEDs, and products containing them, from being imported to the US.
Ford brings Osram into "Focus"Osram has joined forces with the Ford Motor Company to produce a "Focus Concept" car, using Osram s LEDs for many external lighting functions.
The "Focus Concept" car, launched at the Auto China Motor Show 2004, uses Osram s Golden Dragon and TOPLED ranges of LEDs for front turn indicator lights, reversing lamps, brake lights and tail and indicator lights.
Osram claims that its LEDs have offered Ford engineers more flexibility, allowing them to produce reliable, efficient, three-dimensional lamp designs.
