DYK, Circuit Judge.

Rosco, Inc. ("Rosco") appeals the decision of the United States District Court for the Eastern District of New York finding Rosco's design patent, United States Design Patent No. 346,357 ("the '357 patent"), invalid as functional and obvious, finding that Rosco abandoned its claim that Mirror Lite Company ("Mirror Lite") inequitably procured its utility patent, United States Patent No. 5,589,984 ("the '984 patent"), and rejecting Rosco's claims under 15 U.S.C. § 1125(a) of tortious interference with business relations, misrepresentation, and common law trademark infringement. Rosco, Inc. v. Mirror Lite Co., 139 F.Supp.2d 287 (E.D.N.Y.2001). Mirror Lite cross-appeals the district court's decision that the claims of the '984 patent are invalid. Because the district court erred in finding the '357 patent invalid as functional and obvious; finding the claims of the '984 patent invalid under 35 U.S.C. §§ 102(e) and 102(g); and finding that Rosco abandoned its inequitable conduct claims, we reverse in part, vacate in part, and remand. On remand, the district court should make findings and conclusions on all relevant issues as required by Federal Rule of Civil Procedure 52. Fed. R.Civ.P. 52. We affirm the district court's rejection of Rosco's claims under 15 U.S.C. § 1125(a) of misrepresentation and common law trademark infringement.

BACKGROUND

Rosco and Mirror Lite are competitors in the school bus mirror market. This dispute involves "cross-view" mirrors, which are convex, three-dimensional, curved surface mirrors mounted on the front fender of a school bus, enabling the bus driver to view the front and passenger side of a school bus. Rosco filed a complaint on November 19, 1996, and amended the complaint on December 27, 1996 (the "Rosco I case"). A second civil action was subsequently filed by Rosco in October 1999 (the "Rosco II case"). Mirror Lite asserted a counterclaim in the second action. The two cases were consolidated.

Each party owns a patent that it alleged was infringed by the other. Rosco raised a variety of other claims.

1. Rosco's '357 Design Patent

Rosco's '357 design patent relates to an oval, highly convex cross-view mirror with a black, flat metal backing. Rosco applied for the patent on April 14, 1992, and the patent issued on April 26, 1994. Rosco alleged that Mirror Lite infringed the '357 design patent. Mirror Lite argued that the '357 design patent was invalid as functional and therefore was not infringed.

2. Mirror Lite's '984 Utility Patent

Mirror Lite's '984 utility patent relates to an oval cross-view mirror with a varying radius of curvature along the major axis of the convex ellipsoid mirror lens. Mirror Lite filed the parent application that led to the '984 patent on September 9, 1992. The '984 patent issued on December 31, 1996. Rosco requested declaratory judgment that all claims of the '984 patent were invalid as anticipated under 35 U.S.C. § 102(a), invalid for failure to name the true inventor under 35 U.S.C. § 102(f), invalid as previously invented by another under 35 U.S.C. § 102(g), and unenforceable due to Mirror Lite's inequitable conduct in procuring the patent.1 Mirror Lite counterclaimed that Rosco infringed the '984 patent.

3. Rosco's Other Claims

Rosco also alleged that Mirror Lite: engaged in tortious interference with business relations by procuring the '984 patent through inequitable conduct; engaged in misrepresentation by publishing disparaging statements about Rosco's mirrors; and engaged in common law trademark infringement by using the marks "Eagle Eye" and "Mini Eagle Eye" to compete with Rosco's "Hawk Eye" and "Mini Hawk Eye" products.

In the Rosco I case, Mirror Lite moved for summary judgment on all claims, and the district court granted summary judgment as to Rosco's claim of tortious interference with business relations. Rosco, 139 F.Supp.2d at 294-95. The court denied Rosco's motion for reconsideration on August 19, 1999. Id. However, the court later effectively granted reconsideration and reinstated the claim of tortious interference with business relations. Id. at 304 n. 14.

After a bench trial, the district court: found the '357 design patent invalid as functional and obvious under 35 U.S.C. § 103; found the claims of the '984 patent invalid under 35 U.S.C. §§ 102(e) and 102(g); did not reach Rosco's claim for design patent infringement because it found the '357 patent invalid; did not reach Mirror Lite's claim of patent infringement because it found the '984 patent claims invalid; did not address the validity of the '984 patent under 35 U.S.C. §§ 102(a), 102(f), and 103; found that Rosco abandoned its inequitable conduct claims; and rejected Rosco's claims of misrepresentation and common law trademark infringement.

The parties timely appealed. We have jurisdiction under 28 U.S.C. § 1295(a)(1).

DISCUSSION

This case presents an example of the need for clear findings of fact and conclusions of law. Federal Rule of Civil Procedure 52(a) requires that "[i]n all actions tried upon the facts without a jury or with an advisory jury, the court shall find the facts specially and state separately its conclusions of law thereon." Fed.R.Civ.P. 52(a). We have noted the importance of compliance with these requirements, recognizing that one of the purposes of Rule 52(a) is to "provide the appellate court with an adequate basis for review." Gechter v. Davidson, 116 F.3d 1454, 1458, 43 USPQ2d 1030, 1033 (Fed.Cir.1997); see also Pretty Punch Shoppettes, Inc. v. Hauk, 844 F.2d 782, 784, 6 USPQ2d 1563, 1565 (Fed.Cir.1988) ("[T]he trial court must provide sufficient factual findings such that we may meaningfully review the merits of its order."). Here, the district court failed in several instances to make sufficient findings of fact and conclusions of law to provide the necessary predicate for judicial review.

We note also that the parties in this case have made prolix, confusing, and contentious arguments, which no doubt made it particularly difficult for the district court to address the issues with clarity and precision. We trust that, on remand, counsel will provide the necessary assistance to the district court by appropriately narrowing the issues and coherently explaining their respective positions.

I Rosco's '357 Design Patent

"A patent shall be presumed valid." 35 U.S.C. § 282 (2000). To overcome this presumption of validity, the party challenging a patent must prove facts supporting a determination of invalidity by clear and convincing evidence. Apotex USA, Inc. v. Merck & Co., 254 F.3d 1031, 1036 (Fed.Cir.2001), cert. denied, 534 U.S. 1172 122 S.Ct. 1196, 152 L.Ed.2d 136 (2002) (citing Am. Hoist & Derrick Co. v. Sowa & Sons, Inc., 725 F.2d 1350, 1360, 220 USPQ 763, 770 (Fed.Cir.1984)).

Rosco's '357 design patent shows a highly convex, curved-surface, three-dimensional oval mirror with a black, flat metal backing. In May 1992, Rosco began manufacturing the mirror of the '357 patent under the name "Eagle Eye."

Rosco alleged that Mirror Lite infringed the '357 patent by manufacturing and selling a duplicate of Rosco's mirror under the name "Hawk Eye." Mirror Lite argued that the '357 patent was invalid as functional. The district court found the '357 design patent invalid as functional. Rosco, 139 F.Supp.2d at 296.

We apply a stringent standard for invalidating a design patent on grounds of functionality: the design of a useful article is deemed functional where "the appearance of the claimed design is `dictated by' the use or purpose of the article." L.A. Gear, Inc. v. Thom McAn Shoe Co., 988 F.2d 1117, 1123, 25 USPQ2d 1913, 1917 (Fed.Cir.1993) (citing In re Carletti, 51 C.C.P.A. 1094, 328 F.2d 1020, 1022, 140 USPQ 653, 654 (CCPA 1964)). "[T]he design must not be governed solely by function, i.e., that this is not the only possible form of the article that could perform its function." Seiko Epson Corp. v. Nu-Kote Int'l, Inc., 190 F.3d 1360, 1368, 52 USPQ2d 1011, 1017 (Fed.Cir.1999). "When there are several ways to achieve the function of an article of manufacture, the design of the article is more likely to serve a primarily ornamental purpose." L.A. Gear, 988 F.2d at 1123, 25 USPQ2d at 1917 (citations omitted). That is, if other designs could produce the same or similar functional capabilities, the design of the article in question is likely ornamental, not functional. Invalidity of a design patent claim must be established by clear and convincing evidence. Id.

The district court found that because the mirror's oval shape, the asserted point of novelty of the '357 patent, "of necessity dictates its function," the '357 patent was invalid as functional.2 Rosco, 139 F.Supp.2d at 296. The court based its determination of functionality on its findings that the mirror of the '357 patent offered a unique field of view (when compared to Mirror Lite's Bus Boy mirror); that Rosco represented to the Patent and Trademark Office that its mirror provided a superb field of view; and that Rosco marketed the mirror of the '357 patent as more "aerodynamic" than other cross-view mirrors. Id.

The mere fact that the invention claimed in the design patent exhibited a superior field of view over a single predecessor mirror (here, the Bus Boy) does not establish that the design was "dictated by" functional considerations, as required...
