It appears as if Nokia has a bone to pick with HTC, as it filed a new complaint on Thursday with the International Trade Commission. Per complaint, Nokia accuses HTC of shifting responsibility for infringement to its suppliers, something that if it turns out to be true, could mean severe problems for HTC.

Last year, Nokia sued HTC for infringing on multiple patents, and HTC got out of that little problem unscathed, but with this latest complaint, Nokia could be aiming for the jugular to make sure HTC does not escape a second time.

"Nokia has filed further cases in the United States alleging that HTC products infringe additional Nokia patents," Nokia said in a statement to ZDNet.

"We began actions against HTC in 2012 to end the unauthorised use of our proprietary innovations and technologies. Since then, despite the German courts confirming infringements of Nokia patents in HTC products, HTC has shown no intention to end its practices, instead it has tried to shift responsibility to its suppliers. We have therefore taken these further steps to hold HTC accountable for its actions."

The new complaint is directed at the HTC One, and if HTC is found guilty, the phone could be banned from being imported into the United States. Patents blogger Florian Mueller, believes a number of patents relate to chips made by Broadcom and Qualcomm that feature in HTC's flagship One device.

It doesn't quite end there. Nokia has also filed a suit against HTC in the U.S. District Court in California. This new lawsuit has to do with an additional three patents for a "terminal, method and computer program product for interacting with a signalling tag." According to Nokia, HTC infringes on these patents with ten of its smartphones, which includes the HTC One along with the HTC First with Facebook Home.

It would be very interesting to see how all this plays out in the court of law. If it turns out HTC really did infringe on Nokia-owned patents, things could get very ugly.
