I have a problem with your first solution: patents can be owned by companies, correct? And companies can be bought and sold, no? Given how many patent trolls are using the patents of now-defunct entities, I don't think that limiting patent sales would help much, unless you go further and say that any company that is merged or acquired by another must give up its patents (which doesn't seem like a good idea). Another issue with your suggestions: setting arbitrary limits on damages would make patents worthless in protecting truly ground-breaking inventions, like the telephone, for instance.
