Charges: Already embroiled in a costly and exhaustive legal battle with Apple over wireless communication, security, and speech patents that the iPhone allegedly infringes upon, Nokia extended the lawsuit to include the newly launched iPad in 2010.
Complex says: This is the prickliest of Apple's current legal bouts. As the largest mobile handset maker in the world, Nokia has so many mobile communication patents, that if you build a mobile phone, you're gonna have to pay 'em something. The two companies attempted to settle in 2008, with Apple paying a fee and Nokia getting to use some of Apple patents, but that didn't work out. Apple ended up suing Nokia for infringing upon its touchscreen patents. We don't see this one ending anytime soon.
