International Tropic-Cal, Inc. (Tropic-Cal) appeals the decision of the United States District Court for the Central District of California, No. CV 90-89 (February 26, 1990), granting a preliminary injunction to Oakley, Inc. (Oakley) which enjoins Tropic-Cal from infringing Design Patent No. Des. 293,450 (the ’450 patent) and frоm selling any sunglasses which are confusingly similar to Oakley’s sunglasses sold under its “BLADES” and “RAZOR BLADES” trademarks. We vacate the injunction and remand.
I
The matter оf preliminary injunctive relief is committed to the sound discretion of the trial court, and a reversal requires a showing that the trial judge abused his discretion, committed an error of law, or seriously misjudged the evidence.
See Hybritech Inc. v. Abbott Laboratories,
The district court’s findings of facts and conclusions of law in support of the preliminary injunction are sparse. As to the first factor, the court appаrently concluded that Oakley will likely be able to prove (1) that Tropic-Cal has infringed Oakley’s “presumptively valid” ’450 design patent, and (2) thаt Tropic-Cal has violated section 43(a) of the Lanham Act, 15 U.S.C. § 1125 (1988), by marketing sunglasses that are “confusingly similar” to those marketed by Oakley under its “BLADES” and “RAZOR BLADES” trademarks. The preliminary injunction can be supported by a reasonable likelihood of success on either issue.
Rule 52(a) of the Federal Rules of Civil Procedure requires that a preliminary injunction be supported by findings of facts. The test of the adequacy of findings is whether they are sufficiently comprehensive and pertinent to the issue to form a basis for the decision.
Loctite Corp. v. Ultraseal Ltd.,
Although the district court was familiar with the facts and issues in this case as a result of prior litigation between the parties, we must conclude that the court’s findings in this prоceeding are so limited and conclusory that meaningful appellate review is not possible.

II
A. The district court made no express finding that Oakley is likely to be able to prove at trial that Tropic-Cal’s glasses infringe the ’450 patent. Infringement must be gleaned from the сourt’s findings that “Oakley owns ... [the ’450 patent] and produces glasses under that design,” “[t]here is substantial likelihood that Oakley will prevail on the merits” and “[s]ale of infringing merchandise causes ... irreparable injury to Oakley.” We cannot agree that these conclusory findings are sufficient to support a preliminary injunction based on infringement.
In order to find infringement of a design patent, it must be shown that an ordinary observer would be deceived in a manner that would induce him to purchase the accused device supposing it to be the patented design,

Infringement is a question of fact,

B. The district court also based its grant of a preliminary injunction on a likelihood that Oakley will be able to prove that Tropic-Cal has made a false designation of origin undеr section 43(a) of the Lanham Act. In reviewing this decision we apply the law of the Ninth Circuit.
See Atari, Inc. v. JS & A Group, Inc.,
In order for Oakley to prevail on its Lanham Aсt claim at trial, it must show (1) that its product is protectable

and (2) that Tropic-Cal’s glasses create a likelihood of consumer confusion.
Fuddruckers, Inc. v. Doc’s B.R. Others, Inc.,
In assessing whether there is a likelihood of confusion, a court first considers numerous factors and then, based thereon, determines whether there exists a likelihood of confusion. With the analysis so structured, the J.B. Williams [Co., Inc. v. Le Conte Cosmetics, Inc.,523 F.2d 187 (9th Cir.1975) ] and AMF, Inc. [v. Sleekcraft Boats,599 F.2d 341 (9th Cir.1979)] courts held that the determination of what is the state of affairs regarding each factor (a “foundational fact”) is a finding of fact reviewed on the clearly erroneous standard, but the further determination of likеlihood of confusion based on those factors is a legal conclusion. See J.B. Williams,523 F.2d at 191-92 ; AMF, Inc.,599 F.2d at 348-54 (applying two-level test as described here).
Alpha Indus., Inc. v. Alpha Steel Tube & Shapes, Inc.,
The factual elements that make up likelihood of confusion include (1) evidence of actual confusion, (2) the defendant’s intent in adopting the design, (3) similarity of design, and (4) similarity of goods and mаrketing channels.
Fuddruckers,
In determining that “[t]he appearance of Tropic-Cal’s sunglasses is confusingly similar to those produced by Oakley,” it is not evident that the district court considered or found the underlying facts necessary for such a conclusion. The district court’s legal cоnclusion that there is confusing similarity in the glasses is essentially unre-viewable without such findings. As we have said before, these factual determinations must initially come from the district court.
C. Because the district court’s findings of fact are insufficient for proper review of either the infringеment or the Lanham Act issues, we must vacate the district court’s preliminary injunction.

Each party shall bear its own costs.
VACATED AND REMANDED.
Notes
. A product is only protectable under the Lan-ham Act If it is primarily nonfunctional and possesses secondary meaning. While the district court expressly found Oakley’s sunglasses to be nonfunctional, it did not make any such express finding regarding secondary meaning. Because of our decision regarding likelihood of confusion, we need not consider whether the court’s other findings are sufficient to establish secondary meaning.
