material fact and the movant is entitled to judgment as a matter of law.” Fed. R. Civ. P. 56(a). We also review the district court’s dismissal of claims under Rule 12(b)(6) under the law of the regional circuit. CoreBrace LLC v. Star Seismic LLC, 566 F.3d 1069, 1072 (Fed. Cir. 2009). Applying the law of the Seventh Circuit, we review the dismissal on a statute of limitations de- fense de novo, Perry v. Sullivan, 207 F.3d 379, 382 (7th

Wells, 104 U.S. 159, 168 (1881). Courts “will not inquire into the adequacy of the consideration.” Carter v. SSC Odin Operating Co., 976 N.E.2d 344, 352 (Ill. 2012); see also Gavery v. McMahon & Elliott, 670 N.E.2d 822, 827 (Ill. App. Ct. 1996) (“A court’s inquiry into whether a contract is supported by consideration does not extend to examining the adequacy of the consideration.
