Nokia is continuing its battle against Apple by suing the tech giant again, this time claiming the iPhone and iPad infringe five of its 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," Nokia said.

Nokia did not elaborate any further on the technologies and patents involved.

"We've 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 of patent licensing at Nokia.

This isn't the first time Nokia has launched legal action against Apple.

In October last year, Nokia filed a lawsuit against Apple, claiming the iPhone infringed 10 of its patents, including GSM, UMTS, and Wi-Fi standards.

Apple hit back in December, countersuing Nokia and claiming the Finnish mobile phone manufacturer was infringing 13 Apple patents.
