IANAL but the route to resolve this seems to be to challenge the patent on the grounds it should never have been granted and have it overturned, which it looks very much like it would be an easy argument to make, if not easy to achieve in practice.
Your comment seems to relate more to unfairness in [lack of] awards of costs in USA legal proceedings.
If you sue me for something I didn't do then it shouldn't cost me anything; that seems reasonable whether the domain is IPR or any other aspect of life.
