Opinion

[379]*379MEMORANDUM DECISION

NORDBYE, District Judge.

This proceeding is a declaratory-judgment action brought by the plaintiff against the defendant to have United States Letters Patent D-188,491 for the design of a “Ceiling Tile Or The Like” declared invalid and not infringed. The defendant is the owner of the patent in suit and has counterclaimed to have the patent declared valid and infringed by the plaintiff.

Plaintiff is a corporation of the State of Delaware with its principal place of business in St. Paul, Minnesota. Defendant is a Pennsylvania corporation with its principal place of business at Lancaster, Pennsylvania, but licensed to do business and doing business in the State of Minnesota. Jurisdiction of the parties and the subject matter is not disputed.

One Robert F. Green was the applicant for the patent in suit. Defendant is the assignee. The application was filed May 14, 1958, and was granted August 2, 1960. The patent hereafter will be referred to as the Green patent. The patented tile design employs a random arrangement of two different sized punched holes in a ceiling tile. There is a clustering of the larger holes and in the spaces between these clusters there are smaller holes, the larger holes and the smaller holes being bunched together so as to produce a swirl or lace-like effect in an amorphous design. That the design is pleasing to the eye may be conceded. However, Green was not a pioneer in the designing of acoustical tile with punched holes. A patent had been issued to one Prisland on February 3, 1953, and was later assigned to the Celotex Corporation. This tile depicted a two-hole acoustical correction design. Before Green, there was on the market the straight or regular drilled holed tile with the same sized holes used in a geometrical design. Then there was the so-called Skip-A-Hole design, where larger and smaller holes were used in a manner to break the harshness of the straight-holed tile. In early 1950, the plaintiff had on the market a tile with two different sized holes intermixed on the face of the tile (Plaintiff’s Exhibit 213). In addition, Armstrong had its Minatone, a mineral tile, and its Cushiontone, a fiber tile. The prints of the latter two tiles were before the Patent Office when the Green patent application was being considered. The patent examiner first rejected the Green claim in that, in his opinion, it was lacking in invention, and later signed an order in which he allegedly finally rejected the application by reason of Prisland and the two Armstrong products known as the Minatone and Cushiontone tiles, and stated at that time,

“ * * * The slight differences thereover are deemed to involve minor variations rather than being a distinctively new and different design. It is well settled that obvious changes in arrangement and proportioning may be made without the exercise of the inventive faculty.”

It was only after the alleged phenomenal success in the sale of the new tile called Classic made under the Green patent as evidence of public acceptance that the patent was finally granted to Green. And although prints of the Armstrong Minatone and Cushiontone tile were before the patent examiner as depicted in a publication known as Sweet’s Architectural File Catalogue, the Patent Office during the consideration of the Green application never was informed by Green or Armstrong, or anyone else, of Armstrong’s Custom Lay-in Board, a two foot by four foot punched panel which had been on the market long before the Green application. This fiber panel marked as Defendant’s Exhibit 104 and by a twelve inch by twelve inch reproduction thereof as shown in Plaintiff’s Exhibit 269 consists of a one-size punched hole design in the tile in a heterogeneous manner which has a strong eye appeal and was more appealing than the geometric regularity of some of the acoustical tile which was found on the market. While it may be recognized that the Classic tile of the Green patent gives a more flowing effect with the smaller holes filling in the voids [380]*380than the Custom Lay-in Board, the patent examiner recognized that it would not be invention to merely add smaller holes to a tile which had larger holes in view of the prior art. Green merely added smaller holes to the Custom Lay-in Board design so as to provide a more flowing appearance upon close inspection —not, however, when put in place in a ceiling.

True, the witness Hauser, called by the defendant, took the design as depicted in Plaintiff’s Exhibit 269 and put in smaller holes, producing Defendant’s Exhibit 422, and thereby did not produce a design that had the attractive over-all appearance as shown in the Classic tile. But Hauser merely put in holes only slightly smaller than Minaboard holes without any attempt to create a design. Small holes in the voids in Plaintiff’s Exhibit 269 would produce a tile strikingly similar to the Classic tile. However, without any smaller holes added, by placing Plaintiff's Exhibit 269 in a ceiling alongside the Classic tile, it is very evident that the average person would not be able to detect any difference between the two designs. A person reasonably skilled in the art could take the tile design in Plaintiff’s Exhibit 269 and with the purpose of adding to its eye appeal to a purchaser who might closely examine it, and without any inventive skill, create a design that would accomplish everything which Green did. That is, to create some sort of a design for tiles does not necessarily require inventive skill. Any arrangement of elements which results in the same general impression of over-all appearance as disclosed in the prior art does not constitute invention. And this view is fully consonant with the pronouncement of this Circuit in American Infra-Red Radiant Co. v. Lambert Industries, Inc., 1966, 8 Cir., 360 F.2d 977, 987,

“We have held in the past and we continue to hold that ‘invention will not be decided on the narrow issue of degree’, and that the mere changing of form, proportions, or size will not alone constitute ‘invention.’ Swenson v. Boos, 156 F.2d 338 (8 Cir. 1946). This is true even though the change brought about better results. Midland Flour Milling Co. v. Bobbitt, 70 F.2d 416 (8 Cir. 1934). Society has an interest to protect in patent litigation and its interests demand that the complete protection afforded by a patent not be allowed for petty, insignificant, and obvious advances. Cuno Engineering Corp. v. Automatic Devices Corp., 314 U.S. 84, 62 S.Ct. 37, 86 L.Ed. 58 (1941); Ditto, Incorporated v. Minnesota Mining & Manufacturing Co., 336 F.2d 67 (8 Cir. 1964).”

Among the prior art in designs that could be easily adapted for tile by manufacturers, reference may be made to Armstrong’s linoleum which was on the market long before the Green patent was applied for and which was not before the Patent Office. In this linoleum there are depicted two or more different sizes of small elements in a random arrangement with clustering of the different elements as disclosed in Plaintiff’s composite Exhibit 276. This linoleum design bears a marked resemblance to Armstrong’s Classic tile.
