I don't think piercing the corporate veil is the only possible solution, you could legislate that revenue from unlitigated patents couldn't be taken out as profit. Again, that might not be enough and the exact wording would need work, but I think that making it possible is the first step to making it practical. Personally I think we should just abolish the entire patent system, since I really don't see much benefit in it for anyone but large companies, but basically everyone agrees on stopping patent trolls with garbage patents
