Apple Inc sued Ericsson alleging that the Swedish company's LTE wireless technology patents are not essential to industry cellular standards and that it is demanding excessive royalties for these patents. The iPhone maker said it has not infringed on the patents and does not owe royalties for them. Apple says that the mobile telecoms gear maker is seeking royalties for the LTE technology calculated as a percentage of the price of the entire smartphone or tablet. The royalties should be based on the value of the processor chip that includes the technology, Apple said in the lawsuit filed in a federal court in California. http://www.reuters.com/article/2015/01/14/apple-pa...
