Osram Files Patent Infringement Suit
Jun 2004
SAN JOSE, Calif., June 9 -- Osram Opto Semiconductors, a maker of solid-state LED devices, announced today it has filed a complaint against Malaysian LED manufacturer Dominant Semiconductors Sdn. Bhd., alleging it infringes on its LED technology patents.

Osram seeks to enforce nine of its US patents and has requested an order to prevent Dominant's LEDs and products containing them from being imported into the US. One group of patents covers LED technology that enables LEDs to emit white light using a single semiconductor chip. Typical applications include display backlighting for cell phones and automobile dashboards. The other patents involve technology for the electrical connection structure used in many LEDs, including high-power LEDs, often used in automobile lighting applications, including interior lighting and rear-combination light systems.
