Osram filed complaints in Germany and the United States in connection with alleged violations regarding patents for light emitting diode (LED) technology and plans to file another on Tuesday against LG in China, a statement said.
"Osram stresses that Samsung and LG group companies infringe its patents on white and surface mountable LEDs in the US, Germany and as far as LG is concerned, in Japan and China," it added.
LEDs are a key component for television and computer screens.
Osram seeks a court order "to prevent Samsung and LG from importing and selling infringing LEDs and products containing these LEDs," the statement said.
It also seeks compensation from the Korean groups.
