Kаne Enterprises (“Kane”), a commercial barge operator, appeals the dismissal, under Fed.R.Civ.P. 12(b)(6), of its contract claims against MacGregor (USA), Inc., a naval contractor. Finding no errоr, we affirm.
I.
MacGregor contracted (the “prime contract”) with the United States Navy to build and install large ramps on warships. The prime contract did not oblige MacGre-gor to post a performance or payment bond under the Miller Act, 40 U.S.C. § 270a et seq. MacGregor then subcontracted (the “subcontract”) with Halter Marine (“Halter”), inter alia, to store the ramps and transport them when the ships were reаdy for the ramps to be installed. Halter, in turn, sub-subcontracted (the “sub-subcontract”) with Kane, a commercial barge operator, for delivery of the ramps.
The parties to these contracts by and large fulfilled their relevant obligations. The Navy received the ramps and paid MacGregor in full. MacGregor has paid Halter, except for a $150,000 retainage provided for by the subcontract. Kane fully performed its contractual obligation by delivering the ramps. Unfortunately for Kane, however, Halter filed for chapter 11 bankruptcy shortly after Kane had delivered the ramрs; Halter therefore has not paid Kane the approximately $85,000 owed to Kane under the sub-subcontract.
*374 Kane sued MacGregor in Louisiana state court for contractual damagеs. MacGregor removed to the United States District Court for the Eastern District of Louisiana based on diversity of citizenship and moved to dismiss for failure to state a claim upon which relief can be grаnted. The court granted the motion, reasoning that Kane sought to recover from the re-tainage, a right to payment that is property of the Halter bankruptcy estate and over which the Unitеd States District Court for the Southern District of Mississippi, the court in which Halter filed its petition, has exclusive jurisdiction under 28 U.S.C. § 1334(e).
II.
We review
de novo
a dismissal under rule 12(b)(6), applying the same standards as did the district court.
Ramming v. United States,
III.
The district court believed thаt Kane merely sought to recover its contractual damages from Halter by claiming against the retainage owed to Halter by MacGre-gor. This interpretation of the complaint is understandаble. As Kane stated in the district court, “Kane is pursuing an equitable lien claim against MacGregor such that MacGregor will be ordered to pay Kane from the $150,000 owed by MacGregor under the contract [with Halter].” The re-tainage due to Halter from MacGregor, however, is property of the Halter bankruptcy estate. 11 U.S.C. § 541;
In re Glover Constr. Co.,
Kane has not appealed this aspect of the ruling, but it objects that the court did not consider its other claims against MacGre-gor. Though we agree with MacGregor that Kane’s complaint primarily seеks recovery from the retainage, we disagree that Kane’s complaint did not present its other claims. We construe the complaint liberally and acknowledge that it fairly raises a clаim for equitable lien, a third-party beneficiary claim under the prime contract, and a quantum meruit claim. Yet, none of these states a claim upon which relief can be granted. Thus, we affirm. 1
*375
First, Kane has not stated a claim for an equitable lien in any appropriate fund or property. An equitable lien is a “right ... to have a demand satisfied from a
particular
fund or
specific
property.” Black’s Law Dictionary 934 (7th ed.1999) (emphasis added);
see also Dep’t of the Army v. Blue Fox, Inc.,
Kane also argues for a lien against the money already paid to MacGregor by the Navy, but Kane has not identified any legal or factual basis for such a lien. Kane cites only two cases, one of which,
Quality Mech. Contractors, Inc. v. Moreland Corp.,
Yet, Kane does not explain how it could possibly be entitled to an equitable lien against money paid to MacGregor by the Navy. Kane cites subcontract ¶ 2(e), but that paragraph merely allows MacGregor to withhold the retainage from Halter; it does not create a basis for an equitable lien. Kane also cites subcontract ¶ 7(b), but that paragraph obviously protects MacGregor from Halter’s breach of the subcontract, not Kane from Halter’s breach of the sub-subcontract. Kane cursorily cites several other equally irrelevant paragraphs to similar effect.
Second, Kane has not stated a claim as a third-party beneficiary to thе prime contract. “A contracting party may stipulate a benefit for a third person called a third party beneficiary.” La. Civ.Code AnN. art. 1978.
2
“Louisiana law is settled that for there to be a stipulаtion
pour autrui
there must be not only a third-party advantage, but the benefit derived from the contract by the third party may not merely be incidental to the contract.”
Davis Oil Co. v. TS, Inc.,
Under these Louisiana standards, Kane does not qualify as a third-party beneficiary to the prime contaсt’s transportation clauses. The prime contract simply states that MacGregor will ship the ramps via “commercial barge.” This clause hardly manifests a plain intent to *376 make into a third-party bеneficiary an unspecified barge operator several steps down the contracting chain.
The clause does not even mention payment to the operator. The surrounding clauses, which state other modes of transportation for other goods, further support this reasoning. If Kane is a third-party beneficiary under the commercial barge clause, then other shipping companies would become third-party beneficiaries to those clauses. Kane’s implausible argument would erase Louisiana’s distinction between intended and incidental benefits and would crеate dozens of third-party beneficiaries under the prime contract. 3
Finally, Kane has not stated a
quantum meruit
claim against MacGregor. “Quantum meruit is an equitable remedy founded upon the principle that no one who benefits from the labor ... of another should be unjustly enriched at the other’s expense. The doctrine operates, in the absence of a specific contract, to infer a promise on behаlf of the person to whom the benefit is conferred to pay a reasonable sum for the services or materials furnished.”
Brankline v. Capuano,
Neither element is present here. Kane has a specific contract with Halter. Kane may be disрleased that Halter filed for bankruptcy,' but its displeasure does not void the sub-subcontract, and does not allow it to sue MacGregor. Kane’s remedy is a suit for breach of contract against Hаlter, not a quantum meruit claim against MacGregor.
Also, MacGregor was not unjustly enriched; it contracted with Halter, and both parties performed their obligations under the subcontract. Halter may have been unjustly enriched by its failure to рay Kane under the sub-subcontract, but that cannot justify a quantum meruit claim against MacGregor.
The judgment is AFFIRMED. All requests for sanctions are DENIED.
Notes
. MacGregor observed, in its opening brief, that the United States, which Kane attempted to join as a defendant, might remain a party in the district court. If true, this fact .would
*375
have deprived us of appellate jurisdiction, because Kane did not obtain a certificate under Fed.R.Civ.P. 54(b). After supplemental briefing, however, we conclude that Kane never properly served the United States under Fed. R.Civ.P. 4(i). For purposes of appellate jurisdiction, we treat an improperly served defendant as nеver before the district court.
Ins. Co. of N. Am.
v.
Dealy,
. The parties have assumed throughout that Louisiana law governs this case.
. Kane also argues that it is a third-party beneficiary of the subcontract, but it does not specify which clauses of the subcontract confer this putative benefit. We therefore deem this argument waived for failure to brief it adequately. See Fed. R.App. P. 28(a)(9)(A).
