If IPR for screen-rotation ends up with nullifying the patent, can organizations like EFF start doing that pro-actively for other ridiculous patents like One-Click-Buy and Swipe-to-Unlock? Or does the patent-holder have to be proven as a troll?
First, there is the asymmetry of cost, ie. it probably costs less money to file for and be granted a bogus patent than it costs to invalidate said patent.
Secondly, there is the asymmetry of motivation, ie. patent trolls have greater financial motivation to file for bogus patents than other parties have financial motivation to invalidate these patents.
These asymmetries are really the root of the problem. What's really needed is a lobbying group to pass legislation that changes the incentive structure, including, in my opinion, abolishing patents.
The problem here is that many of the organizations who could fund such a lobbying group (like Apple, Google, Microsoft, etc.) have been coopted by the patent system, because they themselves are patent holders.
Actually, its worse than that; they seem convinced that their patents have actual intrinsic value, which kind of makes sense. They spend a lot of money doing research and development, so of course they want to believe that a legal mechanism for preserving the value of that R&D is legitimate.
This whole thing is frustrating...
