(b) Information is material to patentability if it is material under the standard set forth in Therasense, Inc. v. Becton, Dickinson & Co., — F.3d — (Fed. Cir. 2011). Information is material to patentability under Therasense if:

(1) The Office would not allow a claim if it were aware of the information, applying the preponderance of the evidence standard and giving the claim its broadest reasonable construction; or

(2) The applicant engages in affirmative egregious misconduct before the Office as to the information.
