I think that is the material change we need. Patents must be used as an active and relevant part of your product or you don't deserve protection. The point is to encourage innovation and from someone from basically just reselling your idea. If you aren't selling it, then why do you deserve protection?
It makes literally no difference, as the parent comment already mentioned. You deserve protection for coming up with the technology, not for using it. These patent trolls are one of the methods to support a research program. Universities, for example, aren't set up to sell devices. As long as the patent is for some actual innovation, there is nothing wrong with this market structure, economically or morally.
Why? Ideas are cheap, execution is everything and all that. You don't have to literally be the person executing on it, but whoever you transfer or sell the patent to should. I'd be ok with licensing or selling patents to others to build the technology, I'm not ok with licensing or selling the patent to others who will only use it to sue people who do try to build something similar.
The concept of patents was to encourage innovation, not stifle it.
Its also quite common that multiple people invent the same thing at roughly the same time. With these patent trolls, if one of these people gets the invention patented first, but does nothing but rent seeking with it, that will prevent others who came up with the same thing but were too slow to patent it to even try.
Couple that with overly broad, vague or downright invalid patents and you end up with a system that discourages, hinders or puts a large cost on actual innovation. Even if a patent is provably invalid, it costs money in legal fees to get it overturned.
