AFAIK, there is no such thing as "patented features", but rather "features that cannot be implemented without practicing a patent". It sounds like an academic distinction, but the point is that standards themselves typically specify requirements of a feature without specifying the specific techniques or algorithms used to implement them, and patents would cover the latter. So I would not expect that the standard alone is prior art (absent sample code or the like implementing the relevant feature(s)).
