An anonymous reader writes "Apple and Samsung couldn't agree on a patent cross-license even though their CEOs met recently. What could be the reason (or one of the reasons) is that Apple is asking for obscenely high patent royalties. At the March 31 trial an Apple-hired expert will present to a California jury (already the third jury trial in this dispute) a damages claim of $40 per device (phone or tablet) for just a handful of software patents. The patents are related to, but don't cover all aspects and elements of, functionalities like slide-to-unlock, autocorrect, data synchronization, unified search and the famous tap-on-phone-number-to-dial feature. Google says there are 250,000 patentable inventions in a smartphone. On average, Apple wants $8 per patent per device. That would add a patent licensing bill of $2 million to each gadget. So Apple and Samsung will be back to court again later this month."
