Nokia locks horns with Qualcomm in legal struggle

The Wall Street Journal reports that a UK High court Judge has invalidated Qualcomm's claim that Nokia, the world's largest mobile phone manufacturer, infringe over some of its patents.

The case was initially filed by the US company back in May 2006 and involved Nokia's GSM/GPRS/EDGE-only handsets and two Qualcomm's patents.

Since 2006, Qualcomm has filed 11 lawsuits against Nokia and the UK ruling comes after the US International Trade Commission decided that Nokia did not infringe on three Qualcomm patents.

The legal decision sent Qualcomm's shares down, closing 3 percent down on Monday afternoon, at $41.12.

According to a press release issued by Qualcomm, these patents 'cover certain power saving and power control technologies.'

'The UK High Court ruled that, although the Nokia accused products included the patented technologies, the power saving patent is invalid and that the power control patent is partially valid but, insofar as it is valid, is not infringed by Nokia.'

'Qualcomm is actively considering whether to seek permission from the UK court to amend the patents and appeal the decision.'

'The issues in the UK case are not included in the recent consolidation in Delaware.'

'The UK action is limited to Nokia's GSM/GPRS/EDGE products and does not address the need for Nokia to license Qualcomm's patents for Nokia's WCDMA products.'
