Nokia Files Suit Against Apple, Again

May 8, 2010

Nokia said on Friday that it has filed a new lawsuit against Apple, accusing the U.S. firm of infringing five Nokia patents with its latest iPhone and iPad devices.

The suit is the latest in the battle against the two rival companies after Nokia saw a sharp drop in sales while Apple’s iPhone sales are steadily increasing.

“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,” Nokia said in a statement.

The world’s top mobile phone maker said it filed the suit Friday in the Federal district court in the Western District of the U.S. state of Wisconsin.

“Nokia has been the leading developer of many key technologies in mobile devices” the group’s general manager of patent licensing Paul Melin said in the statement.

“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,” he added.

Nokia filed a lawsuit against Apple in October last year for infringing 10 Nokia patents.  Apple fired back in December by countersuing Nokia on allegations that it was infringing Apple patents.

Nokia asked the U.S. International Trade Commission to open an inquiry into alleged infringement of its patents by Apple in late December.

A Nokia spokesman said that “Apple is continuing to seek a free ride on the back of Nokia patents.”

The patents relate to antenna technologies, technologies for enhanced speech and data transmission, and to using positioning data in applications.

“By moving the litigation to another state Nokia is making another move in the complex game of intellectual property chess it is playing with Apple,” Ben Wood, research director at CCS Insight, told Reuters news.

“On this occasion it is interesting to see it choosing patent areas such as antenna design where it has developed competence over many years,” Wood said.
