Nokia launches patent suit over iPad
FT.com / UK - Nokia launches patent suit over iPad
The burgeoning legal challenges to Apple over its rapid advances in mobile computing mounted yesterday when Finland's Nokia launched a patent infringement suit over the iPad.
Nokia accused Apple in a US federal court in Wisconsin of infringing five patents in the iPad, which has sold 1m units since its US debut in March.
Nokia's suit cites technology used to enhance speech and data transmission and antenna innovations that allow for more compact devices.
"These patented innovations are important to Nokia's success as they allow improved product performance and design," the Finnish company said in a statement. Apple had no immediate response.
