German lighting manufacturer Osram GmbH has filed additional patent infringement complaints against South Korean companies amid a global wave of intellectual property disputes in the technology sector.
Munich-based Osram, a unit of German industrial engineering giant Siemens AG, and Osram Opto Semiconductors GmbH said yesterday in a statement that they have recently filed new complaints and legal actions against Samsung Electronics Co and LG Electronics Inc units.
They include a filing with the Seoul Central District Court alleging infringement of Osram patents that calls for the South Korean companies to stop using Osram LED, or light emitting diode, technology without authorization. Also among the actions was a complaint against LG Innotek Co filed with the Korea Trade Commission over alleged -infringement of four LED patents and seeking a ban on exports of some LG Innotek products.
“We respect the property rights of other companies and expect the same from other market participants,” Aldo Kamper, the CEO of Osram Opto Semiconductors, said in the statement.
LG Innotek and Samsung LED Co have also filed various complaints against Osram alleging patent infringement. The spat over intellectual -property for lighting is playing out in South Korea, Germany, Japan, China and the US.
LG Innotek said yesterday in an e-mail that it “would take action after checking out Osram’s petition contents.”
Samsung LED had no immediate comment.
“Osram was forced to take legal action against LG and Samsung in order to stop the unauthorized use of its technology as LG and Samsung refuse to sign any license agreements or pay royalties,” Stefan Schmidt, Osram’s head of media relations, said in an e-mail.
