Osram filed the complaint against LG in June 2011, and also filed a separate complaint against Samsung. These ITC complaints were followed by several other lawsuits between Osram and LG, and between Osram and Samsung.
The judge’s initial determination said that LG’s accused products infringe the asserted claims 1,3,4, 6, 8, 22, 24, 25, 26, 29, 32, 33, and 34 of US patent no. 7,151,283. This patent relates to phosphor conversion for white LEDs.
However, LG’s accused products were found not to infringe various claims of Osram’s US patent no. 7,271,425, which relates to reducing the risk of thermomechanically-induced failures of LED components.
Also, there was no evidence to show that any of the asserted claims in the above mentioned patents are invalid.
The judge’s findings will be assessed by the full commission, according to a Bloomberg article, which quoted an LG spokesperson as saying the company would fight the infringement ruling.
