Nokia has said that the United States International Trade Commission (ITC) has reviewed the Administrative Law Judge’s (ALJ) initial determination in its favor, in the action brought by InterDigital.

The commission concluded that Nokia products do not infringe InterDigital’s patents, and also withdrew the portion of the ALJ’s initial determination that had found the patents valid and enforceable. The commission issued a notice that it found no violation of Section 337 and has terminated the investigation.

However, InterDigital has not agreed to the decision and is convinced that its case against Nokia has merit.

William Merritt, president and chief executive officer of InterDigital, said: We strongly disagree with the commission’s decision. We believe in the merits of our case and are considering a number of options in response to the commission’s decision. Moreover, these patents represent only a small portion of our intellectual property portfolio.

“As I’ve said before, this decision is clearly not the desired outcome, but it does help us identify how to strengthen our portfolio and licensing program moving forward. We remain confident of achieving our goal of licensing all manufacturers of 3G terminal units, as evidenced by our very recent license agreements with Pantech and Cinterion.

The case, filed by InterDigital, alleged that Nokia infringed four patents that InterDigital asserted as essential for the UMTS (3G) mobile standard. This outcome is consistent with a previous judgement in the UK that found several InterDigital patents not to be essential to the UMTS mobile standard, said Nokia.
