Third-party defendant, Cadillac Products, Inc., appeals the judgment of the United States Court of Federal Claims holding that the claims of Penda Corporation’s patent were not invalid and that the U.S. Government used the invention set forth in Penda’s patent without license or lawful right.
Penda Corp. v. United States,
*969 I
On July 20, 1988, the U.S. Postal Service awarded Cadillac a contract to supply ther-moformed plastic pallets. Penda’s U.S. Patent No. 4,428,306 claims pallets constructed of moldable thermoplastic material. On August 31,1989, Penda filed suit in the Court of Federal Claims 1 seeking the recovery of reasonable and entire compensation under 28 U.S.C. § 1498(a) (Supp. V 1993) for the Government’s alleged use, without license or lawful right, of the invention set forth in the ’306 patent. On December 13, 1989, the court granted the Government’s motion to serve Cadillac with notice pursuant to Court of Federal Claims Rule 14(a)(1). 2 Cadillac joined the action as a third-party defendant.
The defendants challenged the validity of the ’306 patent, stating in their answer that the claims of “[t]he patent in suit ... are invalid for failure to comply with the requirements of Title 35 U.S.C. §§ 102, 103 and 112.” Despite their initial general allegation of Penda’s failure to comply with § 112, the defendants subsequently set forth the following in their Memorandum of Contentions of Fact and Law. 3
33. There are two defenses relevant to the validity of the patent claims being asserted before this Court. First, the claimed invention was obvious to one of ordinary skill in the art at the time the invention was made. 35 U.S.C. § 103. Second, the patentees failed to definitely claim their invention in some of the claims. 35 U.S.C. § 112 ¶ 2.
Nowhere in their Memorandum did the defendants raise the 35 U.S.C. § 112, ¶ 1 issues of enablement and best mode. Moreover, the parties’ August 19, 1992 Joint Statement of Issues of Fact and Law addresses the issues of obviousness and claim indefiniteness, but not enablement or best mode.
At trial, the Court of Federal Claims noted that ample prior opportunity existed to raise the issues of enablement and best mode. The court therefore rejected the defendants’ several attempts at trial to elicit testimony regarding compliance with § 112, ¶ 1, holding that the defendants had waived these issues. The court also denied the defendants’ motion for leave to amend their pleadings to add the § 112, ¶ 1 issues. In a thorough, well-reasoned opinion, the court held that the claims of the ’306 patent satisfied the requirements of §§ 103 and 112, ¶ 2, and that the Government used the invention set forth in Penda’s patent without license or lawful right.
Pen-da,
Cadillac and the Government filed their notices of appeal to this court on November 24 and November 26,1993, respectively. On January 21,1994, this court granted the Government’s unopposed motion to withdraw its appeal. On February 3, 1994, Penda filed a motion to dismiss for lack of jurisdiction in this court on the ground that Cadillac lacked independent standing to maintain its appeal. This court denied Penda’s motion and ordered the parties to address the jurisdictional issue in their briefs. Penda Corp. v. United States, No. 94-5035 (Fed.Cir. Feb. 17, 1994) (order).
II
On appeal, Cadillac does not challenge the conclusions of law or the findings of fact of the Court of Federal Claims, but instead asserts that the ’306 patent is invalid for failure to satisfy the enablement or best mode requirements of § 112, ¶ 1. Cadillac argues that it did not waive the § 112, ¶ 1 *970 issues, or alternatively, that it should have been permitted to amend its pleadings to allege such issues. Before any consideration of the merits of these arguments, however, we must decide whether a third-party defendant in the Court of Federal Claims, against which no judgment has been or could be entered, may appeal a judgment against a co-defendant that chooses not to appeal.
Cadillac contends that this court may hear its appeal even though the Government is no longer a party because the Federal Circuit has exclusive jurisdiction “of an appeal from a final decision of the United States Court of Federal Claims.” 28 U.S.C. § 1295(a)(3) (Supp. V 1993). Cadillac contends that since the judgment against the Government is a final decision of the Court of Federal Claims this court
ipso facto
has jurisdiction to hear the merits of Cadillac’s appeal. Cadillac’s plain reading of our jurisdictional statute, however, would allow any person to appeal from a final decision of the Court of Federal Claims. Our statutory jurisdiction is constitutionally circumscribed. Cadillac’s contention fails to recognize that a party appealing from such a decision must nonetheless have standing to do so.
Cf. Boeing Co. v. Commissioner of Patents & Trademarks,
A
The parties here do not dispute that Cadillac agreed to indemnify the Government against liability under its contract to supply thermoformed • plastic pallets, and that Cadillac thus has “an interest in the subject matter of [a] pending action” before the Court of Federal Claims sufficient to confer third-party defendant status at trial under Rule 14(a)(1). Relying on
Kicklighter v. Nails By Jannee, Inc.,
Furthermore, the Court of Federal Claims is without jurisdiction to determine Cadillac’s contractual obligations to indemnify the Government.
See Carrier Corp. v. United States,
Because of the limited subject matter jurisdiction of the Court of Federal Claims, no claim before that court was directed against Cadillac. From the perspective of the Court of Federal Claims, Cadillac was at most a nominal defendant. In any event, we are unaware of any case in which a court has held that a third-party defendant’s status as a party at trial automatically confers Article III standing on such a party seeking appeal.
Cf. Diamond v. Charles,
B
Cadillac also contends that its potential liability as an indemnitor is a sufficient interest to demonstrate standing to appeal. Penda asserts that because the Court of Federal Claims judgment grants relief only against the Government and makes no independent finding of liability against Cadillac, Cadillac is not an aggrieved party
per se.
Indeed, the law is well-settled that a party lacks standing to appeal from a judgment by which it is not aggrieved.
See Knight v. Alabama,
Relying on
Maine v. Taylor,
The law is well-settled that a party is generally not aggrieved by, and thus lacks standing to appeal from, a judgment rendered against a co-party.
See
15A Wright & Miller,
supra,
§ 3902 & n. 11 (collecting eases);
see also Libby, McNeill, & Libby v. City Nat’l Bank,
At the outset, such a contention creates a paradox. Because this court is without jurisdiction to relieve the Government of an ad *972 verse judgment from which the Government no longer appeals, Cadillac’s appeal essentially asks this court to overturn findings and conclusions of the Court of Federal Claims that are unfavorable to Cadillac, and yet to apply such a holding only to Cadillac. Courts, however, have not recognized standing to appeal where a party does not seek reversal of the judgment but asks only for review of unfavorable findings. See 15A Wright & Miller, supra, § 3902 & n. 6 (collecting cases).
Even if Cadillac is ultimately held liable to the Government under their indemnification agreement, Cadillac’s pecuniary interest in this case is indirect and consequential, rather than direct and immediate.
See Libby,
C
Cadillac finally contends that it has standing to appeal because the Court of Federal Claims judgment may preclude Cadillac from raising the issue of patent invalidity in any subsequent district court action by the Government concerning Cadillac’s liability under the indemnification agreement or by Penda alleging infringement by Cadillac.
Under generally accepted principles, however, the Court of Federal Claims judgment cannot support the assertion of issue preclusion against Cadillac by either the Government or Penda. First, the Government and Cadillac were not adversarial parties before the Court of Federal Claims.
Parties who are not adversaries to each other under the pleadings in an action involving them and a third party are bound by and entitled to the benefits of issue preclusion with respect to issues they actually litigate fully and fairly as adversaries to each other and which are essential to the judgment rendered.
Restatement (Second) Judgments § 38 (1980). The Government and Cadillac were allies, not adversaries, on all issues in suit before the Court of Federal Claims. The judgment of that court thus cannot support an assertion of issue preclusion by the Government against Cadillac.
Second, Penda could not assert issue preclusion in a subsequent infringement action against Cadillac because Cadillac was only a nominal defendant before the Court of Federal Claims. 5
A person named as a defendant in an action is not bound by the judgment therein if the subject matter of the action involves an obligation other than his own and that fact is known to the plaintiff.
Id. § 37 cmt. f. Because the subject matter of Penda’s action in the Court of Federal Claims involved the recovery of § 1498(a) compensation from the Government, i.e., involved an obligation other than Cadillac’s, and that fact was known to Penda, the Court of Federal Claims judgment cannot support an assertion of issue preclusion by Penda against Cadillac.
Lastly, neither the Government nor Penda could assert issue preclusion in a subsequent action against Cadillac because our holding today precludes Cadillac, as a matter of law, from obtaining review of the Court of Federal Claims judgment.
Although an issue is actually litigated and determined by a valid and final judgment, and the determination is essential to the judgment, relitigation of the issue in a subsequent action between the parties is not precluded in the following circumstance[ ]:
(1) The party against whom preclusion is sought could not, as a matter of law, have *973 obtained review of the judgment in the initial action; ....
Id. § 28. It is axiomatic that a judgment is without preclusive effect against a party which lacks a right to appeal that judgment. Thus, it is completely circular to argue, as Cadillac does, that it must have a right to appeal to challenge trial holdings when, if such appeal rights are denied, the findings have no preclusive effect.
In sum, Cadillac’s argument that it must be given standing to challenge the judgment because of its preclusive effects is unfounded. Cadillac simply bears no risk from that judgment.
Ill
For these reasons, we hold that Cadillac lacks the requisite standing to prosecute its appeal. Cadillac’s appeal thus presents us with no Article III ease or controversy for decision. Cadillac’s appeal therefore must be dismissed for want of jurisdiction.
DISMISSED.
Notes
. Effective October 29, 1992, the United States Claims Court became the United States Court of Federal Claims. Federal Courts Administration Act of 1992, Pub.L. No. 102-572, § 902(a), 106 Stat. 4506, 4516. For simplicity, we refer to it throughout by its new name.
. Court of Federal Claims Rule 14(a)(1) states in pertinent part:
The court, on its own motion or on the motion of a party, may notify any person with legal capacity to sue and be sued and who is alleged to have an interest in the subject matter of any pending action to appear as a party and assert an interest, if any, herein.
.The Court of Federal Claims requires each party to file a Memorandum of Contentions of Fact and Law in preparation for the pre-trial conference. Fed.Cl.R. 16(a)(2)(iv) and App.G, 1! 11.
. The Court of Federal Claims is without jurisdiction to adjudicate the Government’s claims against third parties unless (1) the Government’s claim is for the recovery of money which it has already paid out to the third party in respect of the transaction or matter which constitutes the subject matter of the suit, or (2) the third party appears and asserts a claim or an interest in a claim against the United States.
See
41 U.S.C. § 114(b) (Supp. V 1993). Furthermore, the Government's claim "for the recovery of money” is intended to apply only to those situations where the Government is sued for money that was incorrectly disbursed to a third party under a mistake of fact or law.
See Bowser, Inc. v. United States,
. We note that while Cadillac is presently a licensee of Penda's '306 patent, having entered into a license with Penda during the pendency of this action, an infringement suit might follow the termination of that license.
