Apple and Nokia continue to slap each others' cheeks. The iPhone maker has landed the latest blow: a lawsuit filed with the High Court in London this week that seeks to have one of the Finns' patents rendered null and void.

The European patent in question covers scrolling on touchscreen handsets, and is one of 37 patents that Nokia has alleged Apple has infringed.

This particular one was among seven such infringement allegations laid before the Dusseldorf court in September 2010. Apple has asked the court to declare the patent invalid, Bloomberg reports.

Nokia has filed lawsuits against Apple here in the US and the Netherlands as well as in the UK and Germany. Apple has filed suits and countersuits in the US and the UK. ®
