hey grellas - I hope you don't mind tangential questions from a trainee. Whilst (clearly) none of us can do more than speculate as to the terms of the licence, I was wondering whether you thought it possible (in light of industry practice) that Apple licensed the patents for anything less than the full remaining term of the patent? Even if so, is the licence likely to be revocable by IV or Lodsys? And what happens to patent licences when the patent they cover is invalidated, further down the line - is it typical to see clawback provisions allowing the licensee to recover money already paid?
