Opinion

ORDER

HOGAN, District Judge.

This is a patent case involving United States Letters Patent No. 3,421,290. The patent was applied for on February 16, 1967 and it issued on January 14, 1969 to the defendant United Air Specialists. The complaint contains two causes of action, the first being for a declaratory judgment declaring the above patent invalid ; the second cause of action is purportedly based on the antitrust laws (Title 15, U.S.C.) and is a treble damage action based on a claimed antitrust assertion of a known invalid patent in various infringement actions brought against customers of the plaintiff; the second cause of action is bottomed on Walker Process Equipment Inc. v. Food Machinery Corp., 382 U.S. 172, 86 S.Ct. 347, 15 L.Ed.2d 247 (1965).

The plaintiffs’ motion for a partial summary judgment in effect seeks a summary judgment “substancewise” in respect of each of the two causes of action.

The plaintiff asserts at least a half a dozen grounds for invalidity. Some are based on defective proceedings — so alleged — in the Patent Office evident by reference to the wrapper; a number are based on 35 U.S.C. § 102. The latter include claims of “was * * * on sale” more than a year prior to filing of the application, that the invention was in public use more than a year prior to application filing, that the invention was described in a printed publication more than a year prior to filing, et cetera. The ground most seriously urged is based on Section (b) of 102 and is this— that the invention involved in this patent “was on sale” in this country more than a year prior to the date of the application. As we have noted, the application was filed on February 16, 1967, so the critical date is February 16, 1966, and the question is whether or not the invention covered by this patent was on sale prior to February 16, 1966. “On sale” of course, in view of case law con[634]*634struetion, is not as simple as it might appear to be.

At first blush it would seem that summary judgment proceedings do not lend themselves to a question of patent validity — if for no other reason, due to the usual presumption attendant upon the issue of a patent.

While that seemed to be the initial reaction of the courts, the reaction has somewhat gone down the drain as a result of what Professor Moore calls an “uphill fight.” The resolution of the question would, of course, depend to a great extent upon the alleged ground of the invalidity. There is not a great deal of relevancy between the usual presumption or the background of the presumption and the question whether or not the invention set forth in the patent was on sale more than a year before the application. Summary judgment proceedings have been held applicable to that type of controversy by the Ninth Circuit in Super Mold Corp. v. Clapp’s Equipment Division, 397 F.2d 932 (9th Cir. 1968). Invalidity based on prior art was the ground for a summary judgment of invalidity in the district court in a case affirmed by the Sixth Circuit — Bobertz v. General Motors, 228 F.2d 984 (1955). See also Plechaty Co. v. Heckett, 145 F. Supp. 805 (N.D.Ohio 1956) — a summary judgment case based on Sections (a) and (b) of 35 U.S.C. § 102. It is concluded that if there is no genuine issue of fact on the record involving the question of “on sale” more than a year prior to application, a summary judgment may be appropriately granted.

The first question, of course, is what was the invention? The answer — and then we will get to the background — is cryptically set forth in the file wrapper and specifically in a memorandum of a conference between the Patent Office Examiner and counsel for the patentees as follows: “The critical features of this invention relate to the location of the inlets and outlets for the smoke removal system with respect to the'entire room.”

The subject dealt with was air cleaning. The object attacked was the removal of smoke or other impurities in the air in as cheap a manner as that could be done. The disclosure was of a “system having a ceiling inlet over the primary smoke source, and a remote clean air outlet in the ceiling, and a blower and air cleaning system providing limited air flow between the outlet and the inlet.” This from the background of the invention (stated in application and patent):

“This invention relates to an indoor air cleaning system and has great and particular utility in the elimination and removal of tobacco smoke from commercial installations such as bowling alleys and the like. The system of this invention includes an electronic air cleaner or precipitator of the type generally in use for related purposes. However, by virtue of the combination as set out hereinafter, the instant invention accomplishes the general objective set out above with the utilization of one-third to one-half the equipment size and power heretofore required.
“That is, existing systems are currently designed for convenient installations as part of a complex heating and/or air conditioning system. In such installations, the air cleaning unit must be sized to accommodate the capacity of the entire system.
“It is a primary object of the instant invention to provide a more efficient air cleaning system for such installations, and at the same time to drastically reduce the size, cost and capacity of the air cleaning equipment.”

There was nothing new about any of the equipment used to accomplish this. The equipment involved the use of a blower and an air cleaner and a diffuser and inlet and outlet piping. Concededly there was nothing new in the combination. Air cleaning equipment in commercial establishments, including bowling alleys, was in use at least by the early 1960’s. This equipment was installed in connection with — not necessarily as a part of but in conjunction with— central heating equipment or central air [635]*635conditioning equipment and the cleaning equipment, that is to say, the air cleaning equipment, operated on all of the air going into or through the central heating or central air conditioning equipment. Of course, the central equipment dealt one way or another with all of the air in the entire installation. The air cleaning adjunct of a central system distinguished not between clean air drawn from one part of a commercial installation in which there was by and large only clean air on the one hand and, on the other hand, smoke-laden air drawn from another part of the same commercial installation. As a consequence the capacity of the air cleaning equipment had to have relationship to the entire air content of the particular.installation involved, just as the air conditioning tonnage or the heat conditioning BTU had to be related. What was new about this invention was this: The inventors started with the recognition that in certain types of commercial installations the smoke or other impurity in the air is not evenly diffused in the atmosphere throughout the entire installation. As a matter of fact, in certain types of commercial installation the heated or cooled air throughout more than one-half of the installation may be quite free of any smoke.
