Nokia on Thursday refused to back down in its patent dispute with Apple and sued the American company in Germany, the Netherlands and the UK. The Dusseldorf, Hague and London complaints accuse Apple of violating 13 extra patents beyond the 24 already leveraged against Apple in the US. Unlike past complaints, Nokia this time was counting on the age of its patents to avoid prior art and covered basic touch interfaces, app stores, messaging and signalling technology that in some cases have existed for years.
