The U.S. International Trade Commission has decided to investigate HTC for patent infringement based on a complaint Nokia filed in May that targets several phones from the Taiwanese handset maker, including the HTC One.
Nokia's complaint is requesting an import ban on the phones for allegedly infringing six of the company's patents. Other handsets named in the complaint include HTC's Droid DNA, the HTC Evo 4G LTE, and last year's generation of HTC One phones.
The International Trade Commission's investigation, announced on Thursday, will deal with Nokia patents that cover video processing, internal smartphone design and radio transceiver technology, among others named in the original complaint.
HTC declined to comment on the case.
Nokia has so far accused HTC of infringing on 50 of its patents in legal action going back to May of last year that has ended up in U.S. and German courts. A month ago, the company filed another lawsuit against HTC with a U.S. federal district court that also claimed several HTC phones, including the HTC One, infringed on three of the company's patents.
"HTC has shown no intention to end its practices," Nokia said in May, "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 Taiwanese smartphone maker has previously faced a U.S. import ban with its products when Apple won a ruling from the International Trade Commission in an earlier patent infringement case. This forced new HTC phones to go through a U.S. Customs review last year to ensure compliance with the ruling, forcing a delay in the company's handset shipments to the country.
