Even-Cut Abrasive Band & Equipment Corp. v. Cleveland Container Co., 171 F.2d 873, 80 U.S.P.Q. (BNA) 385, 1949 U.S. App. LEXIS 4580 (6th Cir. 1949).

Opinion

HICKS, Chief Judge.

The Cleveland Container Company (herein called Container) brought suit under Sec. 400 [now §§ 2201, 2202] of Title 28 U.S. C.A., against Even-Cut Abrasive Band and Equipment Corporation (herein called Even-Cut), assignee-owner of Reissue Patent No. 20,817 — 4938, to Maddox, seeking a declaratory judgment that the reissue was invalid. The complaint also sought to enjoin Even-Cut from making charges that the plaintiff infringed the reissue. The complaint further alleged that Container had a license under the patent through intervening rights, and that Homer Coe, the Manager of Even-Cut, and Rollin Bacher had been guilty of unconscionable conduct with reference to disclosures, which would deprive Even-Cut of ■ any equitable relief against plaintiff.

In a second cause of action plaintiff askedi that the patent be assigned to it because of the unconscionable conduct of Coe and Bacher.

The answer denied the invalidity of the patent and that any matters had been disclosed in confidence to Coe and Bacher, or that Container was entitled to the reissue. For counterclaim, Even-Cut sued Container for infringement of claims 3 and 4 and for an accounting.

The cause was sent to a Master, where Container conceded that it infringed claims 3 and 4, if they were valid. The Master concluded thaj these claims were invalid and that Container had established intervening rights. He further found that the. [874]*874suit should be dismissed as to Coe and Bacher for lack of proof. He dismissed the counterclaim, disallowed costs to Coe and Bacher, and allowed Container costs from appellants.

The court sustained the Findings and Conclusions of the Master, and hence this appeal.

The issues presented here are, — (1) whether claims 3 and 4 are valid; (2) if valid, whether appellee had established intervening rights to the disclosure; and (3) whether appellants are liable for costs and expenses incurred in preparing the defense against the second cause of action which appellee purported to dismiss.

The reissue was for an abrading roll and a method of making it. According to the specification, the roll comprised “a hollow member or body portion, preferably formed of paper board * * * to which the abrasive material is firmly attached by. some adhesive such as glue.” The abrasive covering or sheet was “wound spirally of the roll so that the seams formed by successive convolutions will not produce any markings on the article being sanded.”

The preferred form was similar in appearance to a mailing tube with the outer layer composed of spirally wound abrasive paper. It was claimed for this form that it was evenly balanced and could be mounted by inserting rotatable, tapered spindles at either end and could be operated at high speed and possessed resiliency and a cushioning effect theretofore secured by the interposition of felt or rubber between the abrading material and the base member of the roll. In its construction the support and the abrasive were integrally joined by the adhesive, and being of low cost it could be discarded by removing it from the spindles when the abrasive surface was exhausted.

The above mentioned claims 3 and 4 for a method and an article, respectively, are in issue, and as stated, infringement is conceded.

Qaim 3 reads: “In a method of making a tubular abrasive element, the steps which consist in wrapping spirally upon a hollow mandrel an abrasive coated strip with the edges of adjacent convolutions in contact with each other, and securing said strip to said mandrel by interposing a layer of adhesive.”

Claim 4 reads: “An abrasive element comprising a hollow cylindrical mandrel and a spirally wrapped abrasive coated sheet adhesively secured to said mandrel and completely covering the outer surface thereof, the convolutions of said sheet having adjacent edges in contact without overflowing” (sic).

Article Claim 4. We think that patent No. 681,636 — 19Ü1, to Furber, is the best reference in the prior art. It discloses as a part of the machine a two-ply abrasive belt or 'band which operated over two pulleys as did one form of the commercial product of Container. The specification of Furber called it, — “A belt of abrasive material, such as sand or emery coated cloth or'other flexible material * * * of any suitable construction. It is preferably composed of two strips or layers * * * of suitable textile fabric, cemented or otherwise secured together, each strip having diagonal ends which are abutted, together to form joints * * * extending obliquely across the belt, * * * the said joints being at different parts of the belt, so that each layer extends continuously across the joint of the other layer. * * * This construction provides a strong and durable belt which is not liable to separate at the joints and is free from bunches or ridges thereat, the oblique arrangement of the joints preventing liability of the displacement of the meeting edges of the joint of the outer layer by contact with the work. * * * ” (Italics ours.)

It is manifest from the specifications of both Furber and Maddox that each had two plies secured to each other by an adhesive and that where the edges of the outer layer came together they abutted each other and did not overlap and produce a bump on the band or roll. Furber brought the ends of the outer abrasive layer together diagonally, whereas Maddox abutted the edges spirally.

It is not material to determine whether the diagonal joint of Furber was the equivalent of the spiral joint of Maddox. In the prior art there were several patents for a sand-papering roller or buffing machine [875]*875which utilized the spiral wrapping of the abrasive material on a drum, notably, Patents Nos. 414,115 — 1889 to Kenyon; 906,-035 — 1908 to Kraemer; 732,796 — 1903 to Storm; 1,030,897 — 1912 to Lane; and 1,-469,307 — 1923 to Keltie. These wrappings were used upon permanent drums or rolls and were affixed thereto by mechanical means such as clamps, rather than by adhesives, but they conclusively show that spiral wrappings of abrasive material were known to the art and Kenyon in his specifications expressly stated that there should be no overlapping as the strip was wound spirally around the drum.

We think that Article Claim No. 4 is invalid. We do not consider it as a patentable advance to combine the spiral type disclosed by Kenyon, Kraemer, Keltie and others with the basic disclosure of the two-layered, cemented, abrasive belt of Furber. Both disclosures were in the buffiing art and we think there was no invention in bringing them together in one article. Any good mechanic skilled in the art could have done that. Stockham Pipe & Fittings Co. v. Ohio Steel Fdry. Co., 6 Cir., 78 F.2d 111; Ohio Galvanizing & Mfg. Co. v. Mercury Mfg. Ca, 6 Cir., 49 F.2d 895, 896. See also Hug v. Lakewood Engineering Co., 6 Cir., 7 F.2d 98.

Method Claim 3. This method claim called for wrapping spirally upon a hollow mandrel, an abrasive-coated strip, bringing the edges of adjacent convolutions in contact and securing them to the mandrel by a layer of adhesive.
