RPX[1] is doing some interesting things with Patent Troll Insurance, but it's really only a viable option for huge corporations who want to buy into the troll-defense patent pool.
Actively harmful to the industry. You'll just end up creating similar market forces such as the MPEGLA that is currently making advancement in video compression close to impossible. Troll-defense patent pool simply creates a large artificial barrier to entry into the market.
It's probably better than nothing, but actually removing the patents and allowing open competition is more beneficial for the public and economy overall.
