Wait Too Long and You Might Miss Sum-Thing: ASBCA Again Underscores that Failure to Timely Raise Sum-Certain Defense Can Result in Forfeiture Under New Federal Circuit Precedent

Client Alert | 2 min read | 01.31.24

On remand from the U.S. Court of Appeals for the Federal Circuit, in ECC International Constructors, LLC, ASBCA Nos. 59586, 59643, the Armed Services Board of Contract Appeals concluded that, by waiting until after a hearing on the merits and six years after the appeal was filed, the government forfeited its right to challenge the contractor’s satisfaction of the FAR’s sum-certain requirement for Contract Disputes Act claims.

As we previously discussed, the decision of the Federal Circuit in ECC Int’l Constructors Inc. v. Army reversed longstanding precedent that a claim must state a “sum certain” for a board or court to exercise jurisdiction over an appeal. The underlying appeal dated back to 2014, but the government chose to wait until 2020, after earlier negotiations and a nine-day merits hearing, to challenge the Board’s jurisdiction. Pointing to decades of caselaw, the ASBCA dismissed the contractor’s claim for lack of jurisdiction because the claim had multiple sub-claims and the contractor had not stated a separate sum certain for each sub-claim. On appeal, the Federal Circuit reversed the Board’s decision, holding consistent with recent Supreme Court precedent that the sum-certain requirement is not jurisdictional but, rather, is a claims processing rule that is subject to forfeiture or waiver. On remand, the Board evaluated whether the government forfeited the right to raise its sum-certain argument and held that waiting six years and until after the hearing resulted in forfeiture. Notably, the Board rejected the government’s argument that an exchange during the hearing regarding the sum-certain issue could prevent forfeiture.

This is the second decision out of the ASBCA (following JE Dunn) to apply the Federal Circuit’s ECCI holding. We will continue to monitor additional developments as the Board considers when, and under what circumstances, a party forfeits its right to allege that the other party failed to state a sum certain.

From ‘Second’ to ‘First:’ Federal Circuit Tackles Obvious Claim Errors

Patent claims must be clear and definite, as they set the boundaries of the patentee’s rights. Occasionally, however, claim language contains errors, such as typographical mistakes or incorrect numbering. Courts possess very limited authority to correct such errors. The United States Court of Appeals for the Federal Circuit has emphasized that judicial correction is appropriate only in rare circumstances, where (1) the error is evident from the face of the patent, and (2) the proposed correction is the sole reasonable interpretation in view of the claim language, specification, and prosecution history. See Group One, Ltd. v. Hallmark Cards, Inc., 407 F.3d 1297, 1303 (Fed. Cir. 2005) and Novo Indus., L.P. v. Micro Molds Corp., 350 F.3d 1348, 1357 (Fed. Cir. 2003)....
