A judge for the U.S. International Trade Commission (ITC) ruled today that HTC infringed on two Nokia patents in a preliminary ruling, Reuters reports. The patents relate to the way mobile signals are received and sent on phones and tablets.

The ruling covers a number of the Taiwanese company's products, including the HTC Amaze 4G, the Inspire 4G, the Radar 4G, the Rezound and the HTC Sensation 4G smartphones. It also covers the Flyer and Jetstream tablets. However, it doesn't look like the new ruling will affect HTC's flagship One handset.

Nokia first filed the suit in 2012, and the ITC will make a final decision early next year on Jan. 23, 2014. The U.S. organization is frequently used as a stage for patent infringement charges, thanks to its ability to block the U.S. sale of products more easily than other courts. The Finnish company also filed a much broader complaint with the ITC earlier this year, covering both software and design patents.
