Opinion

TRASK, Circuit Judge:

This appeal stems from a dispute over appellant Carson Manufacturing Co.’s manufacture and distribution of a highway marker which is very similar to a patented marker manufactured and distributed by appellee Carsonite International Corp. Appellant argues that the court below erred in awarding damage and injunctive relief for patent infringement, trademark infringement, and unfair competition based on a jury verdict of appellant’s liability. We reverse.

I

Both parties identify Schmanski Patent 4,092,081 Claim 1, with dependent Claims 12, 13, 17, and 18; and Claim 20, with dependent Claims 24 and 25; as the claims relevant to the patent infringement issues. On this appeal, appellant contends that none of these claims is entitled to a presumption of validity because some prior art references were not cited to the patent examiner in the initial application. It also asserts that the patent is invalid and, in any event, not infringed. Appellee claims that it adequately disclosed the prior art, and that the jury verdict of infringement is supported by substantial evidence.

A

Although the ultimate question of patent validity is a legal one, Graham v. John Deere, 383 U.S. 1, 17, 86 S.Ct. 684, 693, 15 L.Ed.2d 545 (1966) (quoting A & P Tea Co. v. Supermarket Corp., 340 U.S. 147, 155, 71 S.Ct. 127, 131, 95 L.Ed. 162 (1950)), appellant raises two issues which are relevant to the degree of scrutiny that we should give to the judgment below: whether the Schmanski patent is entitled to a presumption of validity, and whether the patent is a so-called “combination patent.”

Under 35 U.S.C. § 282, a patent is presumed valid, and the burden of showing invalidity rests with the party challenging the patent. This presumption of validity can be rebutted only by clear and convincing evidence. Saf-Guard Prods., Inc. v. Service Pts., Inc., 532 F.2d 1266, 1271 (9th Cir. 1976), cert. denied, 429 U.S. 896, 97 S.Ct. 258, 50 L.Ed.2d 179; see St. Regis Paper Co. v. Bemis Co., 549 F.2d 833, 838 (7th Cir.), cert. denied, 434 U.S. 833, 98 S.Ct. 119, 54 L.Ed.2d 94 (1977). However, where the obviousness of a patent as compared to the prior art is in issue and the patent applicant fails to disclose relevant prior art, the presumption disappears. Hewlett-Packard Co. v. Tel-Design, Inc., 460 F.2d 625, 628 (9th Cir. 1972); see Kamei-Autokomfort v. Eurasian Automotive Prods., 553 F.2d 603, 605 (9th Cir.), cert. denied, 434 U.S. 860, 98 S.Ct. 186, 54 L.Ed.2d 133 (1977); Alcor Aviation, Inc. v. Radair, Inc., 527 F.2d 113, 115 (9th Cir. 1975), cert. denied, 426 U.S. 949, 96 S.Ct. 3170, 49 L.Ed.2d 1186 (1976). Nevertheless, the presumption remains intact if the undisclosed prior art is merely cumulative of the cited art. Saf-Guard Prods., Inc. v. Service Pts., Inc., 532 F.2d at 1271 (quoting Schnadig v. Gaines Mfg. Co., 494 F.2d 383, 391 (6th Cir. 1974)).

Claims 20, 24, and 25 are clearly not entitled to a presumption of validity, because they were declared invalid by the examiner during the reissue proceedings. Claims 1, 12, 13, 17, and 18, however, were declared valid even after presentation of previously uncited prior art references during those proceedings.

Only one prior art reference, the Trelleborg patent, was not cited to the examiner at any stage of the proceedings. However, there is nothing about this reference that is not suggested by one or more of the references that were eventually cited to the examiner at some point in the proceedings. Thus, the Trelleborg patent is merely cumulative of the cited art, and, therefore, Claims 1, 12, 13, 17, and 18 are entitled to a presumption of validity.

A combination patent is an invention totally composed of old elements which are combined in an unprecedented manner. See Sakraida v. Ag Pro, Inc., 425 U.S. 273, [668]*668280-81, 96 S.Ct. 1532, 1536-37, 47 L.Ed.2d 784 (1976); M-C Inds. v. Precision Dynamics Corp., 634 F.2d 1211, 1213 (9th Cir. 1980); Herschensohn v. Hoffman, 593 F.2d 893, 895 (9th Cir.), cert. denied, 444 U.S. 842, 100 S.Ct. 84, 62 L.Ed.2d 55 (1977). Such patents are subject to a more rigorous test of validity: A combination patent will be upheld only if it produces an “unusual” or “surprising” result. M-C Inds. v. Precision Dynamics Corp., supra, 634 F.2d at 1213; Hewlett-Packard Co. v. Tel-Design, Inc., 460 F.2d 625, 629 (9th Cir. 1972); Regimbal v. Scymansky, 444 F.2d 333, 337-40 (9th Cir. 1971).1 The rationale for heightened scrutiny of combination patents is to ensure that knowledge is not withdrawn from the public domain into the protected monopoly of one whose invention has not really advanced the art. See A & P Tea Co. v. Supermarket Equip. Co., 340 U.S. 147, 152-53, 71 S.Ct. 127, 130-31, 95 L.Ed. 162 (1950). The issue here is whether each element of the Schmanski patent is old in the art.

It is evident from the record that each element of the patent is indeed old in the art. The fiberglass formula (Claim 1), the variable El concept as it relates to driveability and flexibility (Claim 1), installation by means of driveable rigid-body casings (Claims 12 and 13), the marker’s shape (Claims 17 and 18), and the longitudinal rib supports (Claim 18), are each suggested by one or more of Humphrey, Schmanski-Rose, Barnett, the German patent, and Trelleborg.

Nevertheless, appellee argues that the Schmanski patent should not be considered a combination patent, because it protects a unitary object and not a mechanical or other device composed of discrete component parts. According to appellee, only the latter fall within the definition of a combination patent.

The Schmanski marker does indeed consist of a single tangible element.

Nevertheless, it does not follow that the patent cannot be considered a combination. The defining language used by the cases does not limit combination patents to devices composed of discrete component parts. See, e. g., Great A & P Tea Co. v.
