Nokia Sues Apple Over iPad and iPhone-Related PatentsS

Nokia sued Apple again today, claiming that the iPad and iPhone infringe on five of its patents. The two companies have been throwing lawsuits back and forth for months, making this just the latest salvo in an increasingly bitter feud.

The specific technologies cited by Nokia include enhanced speech and data transmission, using positioning data in applications, and antenna configuration enhancements.

The hostilities began last October, when Nokia first sued Apple for infringing on ten wireless technology patents. Apple responded with a countersuit for thirteen patent infringements. Both of those cases are still pending.

This new suit, which was filed in Wisconsin, seems as though it will trod similar ground, though obviously the iPad 3G is now on the table as an infringing device. We're still waiting to see how Apple responds.

Nokia sues Apple in Wisconsin for infringement of Nokia patents
May 07, 2010

Espoo, Finland - Nokia announced that it has today filed a complaint against Apple with the Federal District Court in the Western District of Wisconsin, alleging that Apple iPhone and iPad 3G products infringe five important Nokia patents.

The patents in question relate to technologies for 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. These patented innovations are important to Nokia's success as they allow improved product performance and design.

"Nokia has been the leading developer of many key technologies in mobile devices" said Paul Melin, General Manager, Patent Licensing at Nokia. "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."

During the last two decades, Nokia has invested approximately EUR 40 billion in research and development and built one of the wireless industry's strongest and broadest IPR portfolios, with over 11,000 patent families. Nokia is a world leader in the development of handheld device and mobile communications technologies, which is also demonstrated by Nokia's strong patent portfolio.
