OSRAM initiates patent infringement litigation against Samsung and LG

7 June 2011 10.30 BST

(Germany) - OSRAM has filed legal actions against Samsung group companies and LG group companies in the US and Germany as well as against an LG group company in Japan.

Based on its contention that these companies, respectively, infringe fundamental patent rights, OSRAM will also file a suit against LG in China tomorrow. With this move OSRAM intends to enforce its patents on Light Emitting Diode (LED) technology.

In these lawsuits OSRAM alleges that Samsung and LG group companies infringe its patents on white and surface mountable LEDs in the US, Germany and, in the case of LG, in Japan and China. OSRAM is seeking to prevent what it believes to be unauthorised use of its technology and to obtain orders from the courts to prevent Samsung and LG from importing and selling any infringing LEDs and products containing these LEDs, such as LED-backlit TV sets and computer monitors. In addition, OSRAM is applying for compensation.

The legal actions focus on LEDs using technologies protected by OSRAM patents. These technologies relate to the electrical and thermal connection structure as well as to conversion technology, which is used, inter alia, to convert the blue light of the LED chip into white light. Typical applications of such white LEDs include, for instance, display backlighting for TV sets and monitors.

A number of companies around the world currently hold royalty-bearing licenses for OSRAM's conversion technology.

“Our objective in taking legal actions against Samsung and LG group companies is to prevent unauthorised use of our valuable technology,” stated Aldo Kamper, CEO of OSRAM Opto Semiconductors. "We have a considerable number of patents which we developed in the course of many years of intensive research and development work. Major competitors such as Philips/Lumileds, Cree, and Nichia have acknowledged our strong IP position by entering into cross-license agreements with OSRAM,” explained Kamper.
