Nokia (NYSE: NOK) checks off another win against Qualcomm (NSDQ: QCOM). The International Trade Commission upheld a ruling in one of their many patent battles on Wednesday, Reuters reported. The agency determined there is no need to review a decision issued on Dec. 12 that found that Nokia did not infringe on three Qualcomm patents at issue in the case and that one of the patents is invalid, a Nokia spokeswoman told the WSJ. Qualcomm said it was disappointed with the ruling and had not yet decided whether it would appeal.

The back story is that Nokia and Qualcomm have been in disagreement since a license agreement expired in April 2007. In 2006, Qualcomm filed a complaint with the ITC, and last week, they agreed to consolidate their dispute. In its complaint, Qualcomm had accused Nokia of infringing on patents that control power to mobile telephones in 2G technology, and asked the ITC to bar the the technology in the U.S. Still, this is not the end of the two company’s disputes—as WSJ notes, the companies have about a dozen legal fights pending on two continents.
