Nokia extends patent infringement suit against Apple

Nokia has filed suit against Apple in the UK, Germany and the Netherlands over the infringement of 13 patents, adding to the allegations of infringement of 24 patents by Apple filed in US courts last year.

The legal battle began in October 2009 when Nokia alleged that the iPhone infringes on Nokia's patents for GSM, UMTS and wireless LAN (WLAN) standards, specifically 10 patents that cover wireless data, speech coding, security and encryption. In December 2009, Apple fired back with a countersuit, alleging that Nokia was infringing on 13 of its patents.

The two sides filed those initial suits over completely different patents. Nokia sued Apple over the inner workings of the iPhone while Apple claimed that Nokia is poaching the user interface from the iPhone.
