No. I'm on position that frivolous patents, like slide to unlock, or page turn, should never be awarded. That's not innovation, it's staking the obvious and it's patent-trolling at its worst. You want to patent something, find something really innovative, like at least at level of Microsoft's 'Metro' and 'Ribbon' attempts at redefine the UI, not something three year old child used 50 years ago, just in digital form.If you don't like the virtual page turn, you need to take the position that all software patents are bad and should never be granted (which, to be fair, might be true).
