That is boiler plate language used by the PTO. Yes, the language is misleading, because it gives you the impression that if the PTO elects to review a patent, that the patent is likely to be invalidated (at least that appears to be your impression). Statistics say that that is not the case as the majority of patents are upheld, but amended.

If you only want to pay attention to some of the facts, and not all of them, yeas, you are misleading.
