Nokia has furthered legal action against Apple, alleging that the company infringes on Nokia’s smartphone patents with its products, including the iPhone, iPad and iPod touch.
This new claim escalates the increasingly tense legal battle between Nokia and Apple. Nokia initially sued Apple for infringing its patents, demanding royalties on iPhones. Apple countersued Nokia later on, claiming Nokia infringed on its patents.
In a press release, Nokia said it will add 13 more Nokia patents to the 24 asserted against Apple in the US.
The claims were filed in the UK High Court, Dusseldorf and Mannheim District Courts in Germany and the District Court of the Hague, Netherlands.
Paul Melin, vice-president of intellectual property at Nokia, says Apple infringed on these patents with its touchscreen technology and its app store.
"The Nokia inventions protected by these patents include several which enable compelling user experiences,” said Melin.
“For example, using a wiping gesture on a touchscreen to navigate content, or enabling access to constantly changing services with an on-device app store, both filed more than 10 years before the launch of the iPhone."
Other patents covered include antenna structures, signal noise suppression, modulator structures, chipsets, messaging functionality and caller ID.
Nokia pointed out that none of these patents were declared “essential to any wireless communication standard,” meaning they are open to be brought to court over.
