LG counter-attacks - Files Patent infringement lawsuit against Osram - Eight Counts of Patent Infringement

On June 6, 2011, Muncih based Osram, one of the top lighting manufacturers in the world, had filed a patent infringement lawsuit against LG Electronics and LG Innotek in the California Northern District Court. Osram had alleged that LG was infringing on 6,812,500 (the ‘500 patent), entitled “Light-radiating semiconductor component with a luminescence conversion element”. The ‘500 patent is related to a light-radiating semiconductor component with a semiconductor body that emits electromagnetic radiation during operation of the semiconductor component. The ‘500 patent primarily discloses light emitting diodes which radiate polychromatic light, in particular white light, with only a single light-emitting semiconductor body.

In a turn of events, on July 15, 2011, Osram found itself on the receiving end, when Samsung filed a request with the United States International Trade Commission to bar products of Osram to enter the US market. To add salt to the wounds, now LG has hit back with a patent infringement lawsuit against Osram. This move is most likely a counter-attack by LG after being sued by Osram.

In the lawsuit filed on July 28, 2011 in the Delaware District Court, LG has alleged that Osram is infringing on eight patents assigned to LG. The patents-in-suit are mentioned below:

7928465: Method of fabricating vertical structure LEDs

7956364: Thin film light emitting diode

6841802: Thin film light emitting diode

7649210: Thin film light emitting diode

7884388: Light emitting diode having a first GaN layer and a first semiconductor layer each having a predetermined thickness and fabrication method therof

7821024: Semiconductor light emitting device having roughness layer

7868348: Light emitting device having vertical structure and method for manufacturing the same

7768025: Light emitting diode having vertical topology and method of making the same
