Apple (NSDQ: AAPL) is doubling down in its patent fight against Nokia (NYSE: NOK), and is hitting Nokia a little closer to home by expanding its lawsuit to Britain. Nokia initially kicked off the legal battle close to a year ago when it filed suit against the iPhone maker in the U.S. Apple filed a counter suit, and is now extending the complaint beyond U.S. borders, Reuters reports.

In Nokia’s original complaint, it alleges that Apple has used 10 Nokia-patented technology standards in the iPhone since its 2007 launch, relating to wireless data, speech coding, security and encryption. In Apple’s U.S. counter suit it charges that Nokia is infringing on 13 iPhone-related patents. According to a Nokia spokesman, the British suit “appear to be based on nine implementation patents already in suit between the two companies in the U.S.”

Currently, the ITC trade body in the U.S. is investigating the two companies’ claims and is expected to make a decision next year before key court hearings in 2012.
