Nokia expands Apple patent suit to include iPad

Nokia on Friday announced that it was again filing suit against Apple over alleged patent infringement in the iPhone and iPad.

Nokia specified five patents in the complaint, relating 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.

"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," said Paul Melin, general manager for patent licensing at Nokia, in a statement.
