I believe that under the US system, that's the *only* path you can take. There is no mechanism for someone to challenge the validity of a patent directly. You can only have a patent struck down by defending yourself from a lawsuit brought by the patent owner. I'm not 100% certain about the EU or UK systems, but I believe they take the same approach.
