OPINION

JOSEPH S. LORD, III, Chief Judge.

Count One of the amended complaint alleges infringement by the defendant of plaintiffs’ patent for a front-discharge concrete mixing truck, and Count Two alleges unfair competition by defendant. Defendant has moved pursuant to F.R.Civ.P. 56(b) for summary judgment as to each count. Defendant contends as to the patent infringement count that the patent held by plaintiffs was invalid ab initio because of obviousness. Defendant seeks summary judgment on Count Two on the grounds that plaintiffs lack standing to sue and that no facts support plaintiffs’ claims.

Because we are unable to resolve at this point at least one factual issue necessary to the determination of patent validity, defendant’s motion for summary judgment as to Count One will be denied. As to Count Two, however, we hold that plaintiffs, as holders of the patent for mixers who are engaged only in the business of granting licenses to manufacture and sell mixers, cannot hold defendant liable for the tort of unfair competition in the manufacture and sale of these products. Defendant’s motion for summary judgment therefore will be granted as to Count Two.

I. THE PATENT INFRINGEMENT CLAIM:

Plaintiffs sue under 35 U.S.C. § 281, alleging the infringement of U.S. Patent No. 2,859,949, issued November 11, 1958, to J. Jack Willard for a Forward Discharging Transit Concrete Mixer (“the Willard patent”). For the purposes of this motion, defendant does not contest either that it infringed the Willard patent or that plaintiffs were the assignees of the Willard patent at the time of the infringement and consequently have the right to maintain this suit under the federal patent laws. The sole basis for defendant’s motion for summary judgment is that the Willard patent was invalid from its inception under 35 U.S.C. § 103, and hence was improperly granted by the United States Patent Office. 1

Section 103 provides in pertinent part: “A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102 of this title, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains.

Non-obviousness has long been recognized as a requirement of patentability, Hotchkiss v. Greenwood, 11 How. 248, 52 U.S. 248, 13 L.Ed. 683 (1851), but it was not included in the federal statutory scheme until the enactment of § 103 in the Patent Act of 1952. The Supreme Court charted the course which trial courts must follow in § 103 cases in Graham v. John Deere Co., 383 U.S. 1, 86 S.Ct. 684, 15 L.Ed.2d 545 (1966). Graham observed that the issue of patent validity (i. e., of obviousness vel non) ultimately is a question of law, Great Atlantic & Pacific Tea Co. v. Supermarket Corp., 340 U.S. 147, 71 S.Ct. 127, 95 L.Ed. 162 (1950), but went on to enumerate three factual inquiries whose resolution must pre *1279 cede the consideration of that ultimate issue. First, what are the scope and content of the relevant prior art? Second, what are the differences between the prior art and the claims raised by the patent whose validity is challenged? Third, what is the level of ordinary skill in the pertinent art? The tripartite factual inquiry mandated by Graham remains the proper approach in a § 103 case. Sakraida v. Ag Pro, Inc., 425 U.S. 273, 96 S.Ct. 1532, 47 L.Ed.2d 784 (1976); Dann v. Johnston, 425 U.S. 219, 96 S.Ct. 1393, 47 L.Ed.2d 692 (1976).

The first two issues of fact, regarding the prior art and the differences between it and the claims of the Willard patent, might well be resolvable at this time. The relevant prior art relied on by defendant includes two types of patents antedating the Willard patent. First, defendant points to U.S. Patent Reissue No. 23,320, reissued in 1951, 2 for a cement mixing drum. The patented invention was of a drum in which concrete could be mixed by rotating the drum in one direction and could be discharged by rotating the drum in the opposite direction. The second category of prior art relied on by defendant includes several patents of what the defendant describes as front-discharge mixers. We find that at least one of these, U.S. Patent No. 1,509,055, issued to Charles Payne in 1924, was indeed for a truck which had front-end discharge of concrete. We hasten to add that although we have all the prior art before us in the form of Patent Office documents, we are reluctant to construe it without the aid of expert testimony. 3

Similarly, we might be able to assess on the basis of these documents the differences between the prior art and the claims of the Willard patent. It is the contention of defendant that the Willard patent merely combines the ingredients of the prior art, by placing a concrete mixing drum of the type described above on a front-discharge mixer essentially like that patented by Payne and others. We will assume, without deciding the matter, that defendant’s characterization of combination is correct. We reiterate, however, our lack of confidence in arriving at such factual findings without hearing adequate expert testimony on the matter.

It is at the final factual stage, the level of ordinary skill in the pertinent art, that defendant’s motion for summary judgment as to patent infringement fails. We note that this factual inquiry actually involves two issues: the definition of the pertinent art, and the ascertainment of the level of ordinary skill in that art. The record in this case is barren as to both of these sub-issues.

The Third Circuit’s case law suggests that this deficiency in the record is fatal. In Systematic Tool & Machine Co. v. Walter Kidde & Co., Inc., 555 F.2d 342 (3d Cir. 1977), the court reversed the district court’s finding that a patent for a tomato-slicing device was non-obvious on the ground that the district court had erred by defining the persons possessed of ordinary skill in the pertinent art to be slicers of tomatoes (i. e., consumers) rather than mechanics. That is, the “hypothetical person having ordinary skill in the art” was defined improperly. Id. at 348 (footnote omitted). Similarly, in Universal Athletic Sales Co. v.
