Opinion

ORDER

BUA, District Judge.

Before the court are defendants’ motions for summary judgment of patent invalidity on the basis of obviousness, aggregation and overclaiming. Defendants have also moved to dismiss certain non-patent claims for lack of jurisdiction over the subject matter and for summary judgment on a remaining non-patent claim.

The patent in suit, United States Patent No. 3,807,110, covers a multipurpose roof penetration curb which is intended to provide a weatherproof seal at points where pipes of various diameters pass vertically through the flat roofs of industrial buildings. The roof penetration curb is comprised of a rubber-like boot in the form of a stepped pyramid, the bottom of which fits snugly over a uniform plastic cap. The cap covers a curb with upright walls which surrounds the opening in the roof through [357] which the pipe passes. The cap may be cut open to accommodate pipes of different diameters without sacrificing the seal’s waterproof feature. Similarly, the rubber boot may be cut away so that the topmost cylinder has an inner diameter which fits snugly against the outer diameter of the pipe passing through its center. To further assure a weatherproof seal, strap clamps are located at points where the top of the boot contacts the pipe and where the bottom of the boot encircles the cap on the curb.

I (A)

Defendants have initially moved for summary judgment pursuant to Rule 56, Fed.R. Civ.P., on two grounds: 1) under Section 103 of the Patent Act, 35 U.S.C. § 103, on the ground that the subject matter of plaintiff’s patent would have been obvious at the time the invention was made to a person possessing ordinary skill in the art to which said subject matter pertains, and; 2) on the ground that the claimed subject matter constitutes an unpatentable aggregation of old elements which perform the same function that they did in the prior art.

Summary judgment is appropriate in patent cases, as in other civil actions, only if there is no genuine issue of material fact in dispute and the moving party is entitled to judgment as a matter of law. Rule 56, Fed.R.Civ.P., Research Corporation v. Nasco Industries, Inc., 501 F.2d 358, 361-62 (7th Cir. 1974), cert. denied, 419 U.S. 1096, 95 S.Ct. 689, 42 L.Ed.2d 688 (1974); A R Inc. v. Electro-Voice, Inc., 311 F.2d 508, 511 (7th Cir. 1962); NCR Corp. v. Eastman Kodak Co., 191 U.S.P.Q. 194, 199 (N.D.Ill.1976). The issue of whether the subject matter of plaintiff’s patent satisfies the statutory requirement of non-obviousness under 35 U.S.C. § 1031 is ultimately a question of law, Pederson v. Stewart-Warner Corporation, 536 F.2d 1179, 1180 (7th Cir. 1976), cert. denied, 429 U.S. 985, 97 S.Ct. 505, 50 L.Ed.2d 597 (1972); E-T Industries, Inc. v. Whittaker Corp., 523 F.2d 636, 641 (7th Cir. 1975), cert. denied, 429 U.S. 870, 97 S.Ct. 182, 50 L.Ed.2d 150 (1976); Panther Pumps & Equipment Co. v. Hydrocraft, Inc., 468 F.2d 225, 227 (7th Cir. 1972), cert. denied, 411 U.S. 965, 93 S.Ct. 2143, 36 L.Ed.2d 685 (1973); Armour & Co. v. Wilson & Co., 274 F.2d 143, 156 (7th Cir. 1960), but requires several factual inquiries to be made prior to its resolution. Graham v. John Deere Co., 383 U.S. 1, 17, 86 S.Ct. 684, 15 L.Ed.2d 545 (1966). Under 35 U.S.C. § 103, the court must ascertain: 1) the scope and content of the particular art at the time of invention; 2) the differences between the state of the art at that time and the claims at issue, and; 3) the level of ordinary skill in the art during the questioned period. Id. See also Sakraida v. Ag Pro, Inc., 425 U.S. 273, 280, 96 S.Ct. 1532, 47 L.Ed.2d 784 (1976).

Defendants cite examples of prior art in an attempt to illuminate the state of the art at the time the patented subject matter was invented and thereby show that plaintiff’s invention was obvious to persons skilled in the art. It is significant to note in this respect that an issued patent is presumed valid under 35 U.S.C. § 282 and that clear and convincing evidence of invalidity is therefore necessary to overcome that presumption. Laser Alignment, Inc. v. Woodruff & Sons, Inc., 491 F.2d 866, 871 (7th Cir. 1974), cert. denied, 419 U.S. 874, 95 S.Ct. 135, 42 L.Ed.2d 113 (1974); Walt Disney Productions v. Fred A. Niles Communications Center, 369 F.2d 230, 234 (7th Cir. 1966); Bela Seating Company, Inc. v. Poloron Products, Inc., 297 F.Supp. 489, 507 (N.D.Ill.1968), aff’d 438 F.2d 733 (7th Cir. 1971), cert. denied, 403 U.S. 922, 91 S.Ct. 2228, 29 L.Ed.2d 701 (1971). This presumption is strengthened when the prior art references, or equivalent references, relied [358] upon by the party claiming invalidity were considered by the patent examiner before granting the patent. Laser Alignment, Inc. v. Woodruff & Sons, Inc., 491 F.2d at 871; Ekstrom-Carlson & Co. v. Onsrud Machine Works, Inc., 298 F.2d 765, 768 (7th Cir. 1962), cert. denied, 369 U.S. 886, 82 S.Ct. 1160, 8 L.Ed.2d 287 (1962); American Needle & Novelty Co. v. Schuessler Knitting Mills, 258 F.Supp. 98, 105 (D.C.Ill.1966), modified on other grounds, 379 F.2d 376 (7th Cir. 1967). Conversely, there is no presumption of validity with respect to pertinent prior art not considered by the examiner in connection with the patent application. Fredman v. Harris-Hub Co., 442 F.2d 210, 214 n. 10 (7th Cir. 1971); T. P. Laboratories, Inc. v. Huge, 371 F.2d 231, 234 (7th Cir. 1966); Skirow v. Roberts Colonial House, 361 F.2d 388, 390 (7th Cir. 1966); Kalkowski v. Ronco, Inc., 424 F.Supp. 343, 352 (N.D.Ill.1976); Namirowski v. Nabisco, Inc., 421 F.Supp. 349, 352 (N.D.Ill.1976).
