Taxing patents doesn't solve anything. It's already expensive to try and patent an idea due to essentially needing a lawyer in order to get the language right, and the only defense startups have against patent trolls and huge companies suing them out of existence is their own patent portfolio. I've got 3 or 4 patentable ideas but no way to patent them because its too expensive. On the other hand, I'm sure Apple would have no problem stealing my idea, patenting it, and then suing me for using my own idea. If you think that can't happen, you obviously don't realize just how broken the patent system is.
