Biomet, Inc. appeals the decision of the United States District Court for the Southern District of Florida 1 granting Dr. Raymond G. Tronzo post-judgment interest from August 6, 1996 on his punitive damages award. We conclude that interest on this part of the judgment runs from the date of the district court’s Fourth Amended Final Judgment, July 27, 2001, entered after appellate reversal of the reduction in punitive damages.
DISCUSSION
In Dr. Tronzo’s suit against Biomet the jury rendered special verdicts of patent infringement, fraud, and breach of confidential relationship. The jury awarded Dr. Tronzo compensatory damages of $3,805,000, which the district court enhanced by $1,902,500 based on the verdict of willful infringement, and punitive damages of $20,000,000.
Tronzo v. Biomet, Inc.,
Back in the district court, the parties disputed the calculation of interest on the punitive damages. Dr. Tronzo argued that interest should run from the initial judgment in 1996, while Biomet argued that it should run from the date of the district court’s action on this court’s mandate in Tronzo IV. The district court agreed with Dr. Tronzo, and awarded interest from the 1996 date. Tronzo v. Biomet, Inc., No. 91-8175 (S.D. Fla. July 27, 2001, corrected August 20, 2001) (Tronzo V). This appeal by Biomet followed.
I
Interest on a judgment in a civil case runs from “the date of the entry of the judgment” in the district court. 28 U.S.C. § 1961. Rule 37(a) of the Federal Rules of Appellate Procedure provides that if a money judgment is affirmed on appeal,
Rule 37(a). Unless the law provides otherwise, if a money judgment in a civil case is affirmed, whatever interest is allowed by law is payable from the date when the district court’s judgment was entered.
When a money judgment is modified or reversed on appeal, the appellate court is required to decide questions of interest:
Rule 37(b). If the court modifies or reverses a judgment with a direction that a money judgment be entered in the district court, the mandate must contain instructions about the allowance of interest.
Precedent establishes that when, as here, the appellate court’s mandate did not contain the requisite instructions, the district court is powerless to award interest other than as provided in 28 U.S.C. § 1961, that is, from the date the district court enters judgment on return of the mandate.

16A Charles Alan Wright, Arthur R. Miller & Edward H.
Cooler, Federal Practice & Procedure
§ 3983 (3d ed. 1999) (“If the mandate of the court of appeals says nothing about interest, despite the command of Rule 37, it will be assumed that interest commences from the date of entry of the appellate court judgment.”);
Briggs v. Pennsylvania R. Co.,
Biomet argues that because the award of Tronzo I was reduced to $52,000 by the district court in Tronzo III, and was restored to $20,000,000 only by Tronzo IV, the judgment was necessarily “modified” in terms of Rule 37(b). Dr. Tronzo argues that the reduction of the award in Tronzo III should be deemed a nullity, for our decision in Tronzo IV was on the basis that the district court had no authority to reduce the initial award. Dr. Tronzo states that Rule 37(a) is the applicable rule, and that our failure in Tronzo IV to comply with Rule 37(b) invoked Rule 37(a) as to the initial award.
Dr. Tronzo also states that Rule 37(b) does not apply because our decision in
Tronzo IV
did not “modify or reverse” the district court’s judgment but simply corrected an action that the district court had no authority to take, and because in
Tron-zo IV
we did not “direct the entry of a money judgment.” Dr. Tronzo bases this conclusion on the absence of the word “remanded” from our judgment in
Tronzo IV,
which concluded with the phrase “affirmed-in-part and reversed-in-part.” However, all appellate judgments are returned to the district court for entry and implementation; the district court regains jurisdiction when the appellate mandate issues.
See Exxon Chemical Patents, Inc. v. Lubrizol Corp.,
Our decision in
Tronzo IV
did “modify or reverse” the district court’s judgment in
Tronzo III,
for absent our decision the punitive damages were set at $52,000. Thus Rule 37(b) should have been followed, and our decision in
Tronzo IV
was flawed in its failure to instruct as to interest. The Advisory Committee Notes to Rule 37 state: “Since the rule directs that the matter of interest be disposed of by the mandate, in cases where interest is simply overlooked, a party who conceives
Upon this appellate lapse, the dispute as to interest was presented to the district court. However, the responsibility and authority for this determination is assigned to the appellate tribunal. On this appeal, we give the matter plenary review.
II
The application of Rule 37 is not unique to judgments in patent cases, and thus we look to the law of the regional circuit for guidance.
See Transmatic, Inc. v. Gulton Industries, Inc.,
Guidance has been provided by the Court in
Kaiser Aluminum & Chemical Corp. v. Bonjorno,
The Court in
Kaiser
established a “meaningful ascertainment” test for determining when post-judgment interest should begin, measured by when the amount of damages was meaningfully ascertained. Within this framework, the courts have continued to exercise discretion under Rule 37(b), implementing the underlying principle of adequacy of compensation through interest.
See DeLong Equipment Co. v. Washington Mills Electro Minerals Corp.,
In
DeLong Equipment, supra,
the court pointed out that “[m]uch of the case law indicates that an appeals court has discretion to select an appropriate date from which interest should run.”
Even if this [failure to award interest from the first judgment] is the result of inadvertence on the part of the appellate court, the appropriate procedure is to file a motion to reform the mandate under Federal Rule of Appellate Procedure 37. Since no such motion was filed, we reverse the district court insofar as it awarded post-judgment interest on Vickers’ future losses, and render the judgment to grant interest on the award of $119,554.00 from September 29, 1988, the date of the second judgment in this case.
Applying this principle, we vacate the award of post-judgment interest from August 6, 1996, and conclude that interest shall accrue from the date of the final judgment entered in the district court after the mandate issued in Tronzo IV, viz. July 27, 2001.
No costs.
VACATED, MODIFIED.
