BRI and how it increases an obviousness determination

Owens Corning v. Fast Felt (Fed. Cir. 2017) illustrates an example of how the broadest reasonable interpretation (BRI) standard increases the chances that an obviousness argument could successfully invalidate a patent claim during a post grant patent review proceeding; and make it more difficult to overcome an obviousness rejection during patent prosecution. It also illustrates how broadening a claimed invention’s field of use could be detrimental to the claim’s validity and make it harder to overcome an obviousness rejection.
