AU Optronics, the world’s No.4 flat panel maker, said a US trade body had affirmed an earlier ruling that the Taiwanese company did not violate patents owned by Thomson Licensing.
The International Trade Commission upheld a preliminary decision that AU did not infringe on any valid claim of patents asserted by Thomson, AU said in a brief statement on Sunday. It did not elaborate.
The case, brought by Thomson in 2010, concerned LCD panel display technologies. The company had sought a ban on imports into the US of some AU products.
Thomson is a unit of French digital video firm Technicolor, which is restructuring after financial difficulties.
