This case is one of several nationwide in which A.J. Canfield Co. (“Canfield”) is attempting to prevent competitors from using the name “chocolate fudge” for diet sodas. Canfield brought this action in 1985, raising an unfair competition claim under section 43(a) of the Lanham Act, 15 U.S.C. § 1125(a), as well as pendent state law allegations against Vess Beverages, Inc. (“Vess”). Vess, based in St. Louis, had sought to market a diet chocolate fudge soda in its distribution area. On July 12, 1985, Judge Shadur denied Vess’ summary judgment motion and granted Canfield a preliminary injunction.
A.J. Canfield Co. v. Vess Beverages, Inc.,
In 1987, Vess returned to court with a motion for summary judgment and to vacate the injunction. The basis for the motion was collateral estoppel, in light of two cases decided after
Vess I,
both of which held that “chocolate fudge” as applied to diet soda is generic and therefore not pro-tectable.
A.J. Canfield Co. v. Honickman,
Judge Duff denied the motion.
A.J. Canfield Co. v. Vess Beverages, Inc.,
Collateral estoppel, or issue preclusion, precludes relitigation of an issue a party has previously litigated and lost.
See Gilldom Sav. Ass’n v. Commerce Sav. Ass’n,
The burden of proving the elements of issue preclusion rests on the party claiming estoppel.
Gilldorn,
(1) the party against whom the doctrine is asserted was a party to the earlier proceeding; (2) the issue was actually litigated and decided on the merits; (3) the resolution of the particular issue was necessary to the result; and (4) the issues are identical.
Kunzelman v. Thompson,
Canfield, a party to the
Honickman
and
Yoo-Hoo
cases, does not challenge Vess’ assertion that the genericness issue was actually litigated and necessary to the results in those proceedings. In both cases,
*38
the ultimate decisions denying injunctive relief were based on a finding that “chocolate fudge” is generic.
See Honickman,
Yoo-Hoo
is perhaps the clearest case. After the district court denied Canfield’s request for a preliminary injunction, finding that Canfield was unlikely to show that “chocolate fudge” is not generic, the court gave Canfield the opportunity to present further evidence before an ultimate decision on genericness.
See Yoo-Hoo,
Likewise, in
Honickman
the Third Circuit conclusively held that “chocolate fudge” is generic.
See
Nonetheless, this court has held that, in certain fare instances, decisions granting or denying preliminary relief will be given preclusive effect.

Miller’s
expansive view of collateral es-toppel has not been widely followed. But here the case is directly on point. The Third Circuit’s decision in
Honickman,

Canfield contends, and the district court found, that Yoo-Hoo and Honickman were not earlier determinations because Judge Shadur in Vess I “necessarily” held that “chocolate fudge” is not generic. Therefore, Judge Shadur’s was the first determination on the question, becoming the law of the case as well as preventing Yoo-Hoo and Honickman from having preclusive effect.
Canfield’s precise argument is that Judge Shadur “specifically found that CHOCOLATE FUDGE was not a generic term when used in association with Can-field’s soft drink.” Brief for Plaintiff-Ap-pellee at 11. That statement is unaccompanied by citation to the opinion, which is not surprising given that Judge Shadur made
no
explicit finding as to whether the term
*39
is generic. In granting the preliminary injunction, he briefly discussed the issue but the opinion never resolves the question. Judge Shadur simply states that “a word or phrase
may
be generic in one usage and
may
function as a trademark in another.”
Vess I,
Judge Duffs approach in
Vess III
differed slightly from that taken by Canfield. He felt that Judge Shadur, in denying Vess’ summary judgment motion,
implicitly
held that “chocolate fudge” is not generic. Judge Shadur rejected the motion because “[tjhere is a genuine issue of material fact as to whether ‘Chocolate Fudge’ has in fact obtained ... secondary meaning.”
Vess I,
That inference, while certainly plausible, is not compelled by Judge Shadur’s opinion. Ordinarily, a court should determine gener-icness prior to examining secondary meaning. But there is no evidence that Judge Shadur made a finding on genericness in this case. The summary judgment section of the opinion is silent on the question, and it is only briefly and inconclusively discussed in the injunction ruling. In granting preliminary relief and denying summary judgment, Judge Shadur made it clear that he was making no final determinations. See id. (reiterating that discussion concerns likelihood of success); id. at 1089 (court may later determine that injunction was improperly issued because term is neither suggestive nor “merely descriptive”). Given the general presumption against giving preclusive effect to preliminary rulings, and given the paucity of evidence that Judge Shadur actually found “chocolate fudge” not generic, we cannot find that Vess I conclusively resolved the issue. Vess I was therefore not a final determination for estoppel purposes.
This court affirmed the
Vess I
injunction in
Vess II.
On the genericness point, as Judge Duff correctly noted, we “merely opined that CHOCOLATE FUDGE was probably not a generic term.”
Vess III,
Canfield argues that the issues are not identical. Specifically, it contends that “chocolate fudge” may be generic in the eastern United States but not in the Midwest. A few cases have held that a term may be generic in one market and not generic in another.
See Anheuser-Busch, Inc. v. Stroh Brewing Co.,
Canfield’s final argument is that
Yoo-Hoo
and
Honickman
should not be given preclusive effect because they are inconsistent with prior determinations of the issue.
See Restatement (Second) of Judgments
§ 29 (1982). Once again, the argument was not raised below; so it is waived. Were we to reach the merits, we would still reject it. The inconsistent prior determination argued by Canfield is
A.J. Canfield Co. v. Concord Beverage Co.,
Canfield also tries a more expansive variation of this argument, using it to attack the Third Circuit’s reasoning in Honick-man. Canfield in essence wants to allow relitigation of the issue in the guise of showing that Honickman was inconsistent with prior caselaw. We refuse to undertake such analysis. Restatement section 29 is intended to allow relitigation where there are conflicting decisions precisely on point. The exception would soon swallow the rule if it allowed for relitigation whenever a losing party felt that the reasoning of an opinion was inconsistent with the reasoning of prior cases in the same general area. Canfield lost on this question in two earlier cases; what we think of those courts’ analyses is not relevant.
In short, we must reverse the decision for Canfield. Two courts determined that “chocolate fudge” as a description of soda is generic prior to any determination of the issue in this case. Canfield’s other arguments were not presented below and are therefore waived. We vacate the injunction and the denial of Vess’ summary judgment motion, and remand so that the district court may enter judgment for the defendant and address Vess’ plea for damages.
VACATED AND REMANDED.
Notes
. Canfield’s appeal was dismissed by stipulation of the parties. Appendix at 21.
. By contrast, Judge Shadur’s opinion in Vess I barely touches upon genericness in the preliminary injunction ruling, and Canfield is forced to argue based on inferences from the opinion’s silence. This sort of speculation does not justify deviation from the general rule that such determinations are not given preclusive effect. See infra pp. 39-40.
. We note in passing that the record clearly shows that Canfield never considered this a geographically limited case. It requested and received nationwide injunctive relief against Vess.
