Nokia has thrown down the gauntlet at Apple by filing a lawsuit, with the Federal District Court in the Western District of Wisconsin, claiming that vital technology powering the the iPad 3G and the iPhone has infringed five patents in its portfolio.
These, Nokia said (opens in new tab), include intellectual property associated with "enhanced speech and data transmission, using positioning data in applications and innovations in antenna configurations that improve performance and save space, allowing smaller and more compact devices".
Paul Melin, the head honcho of Nokia's patent department, said that "Nokia has been the leading developer of many key technologies in mobile devices. We have taken this step to protect the results of our pioneering development and to put an end to continued unlawful use of Nokia’s innovation."
The world's biggest mobile phone manufacturer said that it has spent more than 40 billion Euros over the past 20 years to amass and built an impressive portfolio of patents, around 11,000 of them.
Apple and Nokia are also locking horns in two other patent infringement lawsuits that both companies have filed against each other back in October and December. Apple has also launched legal proceedings against rival smartphone maker HTC over alleged patent violations.
Apple announced the release of the iPad in the UK on Friday with the launch of the iconic tablet reader expected to come on the 28th of May.
