Nokia filed additional patent infringement claims against HTC on Thursday, according to reports.

All Things D reports that Nokia has filed a second complaint with the U.S. International Trade Commission, as well as a federal suit in Southern California, against the Taiwanese handset maker.

The federal suit involves three patents related to "terminal, method and computer program product for interacting with a signaling tag," according to the court filing. It asks the court for a halt of the alleged infringement and unspecified damages.

Patents blog Foss Patents reports that the ITC complaint involves at least two patents, the HTC One, and radio-frequency technology.

Nokia's latest complaints come on top of a massive lawsuit campaign against HTC, RIM, and Viewsonic, in the U.S. and Germany, that the Finnish phone maker started over a year ago.

"We began actions against HTC in 2012 to end the unauthorized use of our proprietary innovations and technologies," Nokia said, according to All Things D. "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."

In April, Nokia won an injunction from an Amsterdam District Court preventing sales of the microphone used for the HTC One. The ruling was limited to the Netherlands.
