After Samsung vs Apple, it’s time for another big patent battle in the world of technology. This time around it’s Nokia and HTC taking to the courts, with the Finnish company filing yet another complaint with the International Trade Commission (ITC) against HTC’s use of its “proprietary” technology.

The patents claimed to have been infringed relate to chips made by Broadcom and Qualcomm, and according to a report by ZDNet, these are present in the HTC One as well. There is another patent for a “terminal, method and computer program product for interacting with a signalling tag”, which Nokia has claimed is infringed by several HTC phones, including the Facebook Home-running First and the flagship.

More trouble for HTC One?

More trouble for HTC One?

A statement from Nokia says that HTC began infringing on some of the former’s patents last year. “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 (like the HD Microphone), 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 statement said. If the complaint is successful, then it could lead to the HTC One being banned from sale.

This latest complaint means that some 50 patents have been included by Nokia in lawsuits around the world, mostly targeting HTC devices. Most recently, Nokia scored a victory over HTC when an Amsterdam court granted preliminary injunction to Nokia over the use of a pair of high-amplitude microphones in the One. At the time, HTC had said, “We are considering whether it will have any impact on our business and we will explore alternative solutions immediately.” And later the company was forced to remove the mention of HD Microphone from the specs sheet of the HTC One.

In another instance, Nokia lost two patent suits when the District Court of Mannheim in Germany ruled that HTC did not infringe on a patent covering a “method for using services offered by a telecommunication network, a telecommunication system and a terminal for it.” This particular patent was targeted at crippling HTC’s phones by banning the use of Google Play Store, according to experts.

Nokia did get a victory in Germany when the Mannheim Regional Court ruled in March that HTC violated a patent on “reduction of power consumption in a mobile station”. Interestingly, HTC said that this was an insignificant victory for Nokia because the devices affected were Wildfire S, Desire S and Rhyme, which are no longer being imported to Germany.
