Robinson Aviation, Inc. v. Barry Corp., 106 F. Supp. 514, 95 U.S.P.Q. (BNA) 78, 1952 U.S. Dist. LEXIS 4044 (D. Mass. 1952).

Opinion

SWEENEY, Chief Judge.

This is an action for infringement of patent No. 2,425,565 issued August 12, 1947, covering a vibration absorption mount, in which plaintiffs seek damages' and an injunction. Claim 1 alone is in suit.

Defendant has admitted by stipulation that its type 770, 780, 860, 980 and 896 mounts infringe Claim 1 of the patent if it is valid, but asserts that the patent is invalid and seeks by way of counterclaim for a declaration of this Court to that effect.

In the complaint plaintiffs also allege that defendant’s type M-112 infringes Claim 1. However, during the trial plaintiffs admitted that this contention was not well founded and accordingly the complaint will be dismissed as to this item.

Findings of Fact

The plaintiff Robinson Aviation, Inc. is a New York corporation having its principal place of business at Teterboro, New Jersey. Cecil S. Robinson and Dorothy H. Robinson are residents of New Jersey and officers of Robinson Aviation, Inc. The patent in suit was originally owned outright by Cecil S. Robinson, but he assigned a one-half interest in the patent to his sister Dorothy H. Robinson. Robinson Aviation, Inc. is a licensee of the patent. Defendant is a Massachusetts corporation, having a place of business at 700 Pleasant Street, Watertown.

*516 The patent relates to mechanical vibration absorption units which are mountings for absorbing or reducing vibrations or shock that would otherwise be transmitted to delicate instruments on mobile vehicles, particularly airplanes. The unit is intended to carry the absorption down to practically invisible vibrations. In order to accomplish this result each unit possesses a three-way freedom of movement, absorbing vibrations which push up and down in a vertical direction and those which occur laterally. In the normal case four of these devices are under and attached to each corner of the supported member, such as an airplane camera.

Claim 1 in suit reads as follows:

“In a vibration absorption mount, the combination of a casing having an opening, a resilient grommet in said opening adapted to receive impacts from above, below and sideways, a mounting stud extending thru said opening but normally not touching the grommet except under excessive shock or vibration, a flange on said stud, and a main resilient member supporting said flange in said casing, said resilient member being so proportioned that the flange will float out of contact with said grommet under normal operating conditions so as to absorb vibrations reaching the casing, said grommet and flange impinging in case of excessive axial shock or vibration, and said stud and grommet impinging in case of excessive lateral displacement.”

Reduced to its barest essentials, the claim in suit covers five elements which consist of a case with a round opening on the top of it, a resilient grommet inserted in the case, a stud inserted within the grommet but floating in such a manner as not to touch the grommet, and on the end of the stud is a flange which is supported by a resilient ball-like member.

The Question of Invention

The U. S. Supreme Court in Great Atlantic & Pacific Tea Co. v. Supermarket Equipment Corp., 340 U.S. 147, 71 S.Ct. 127, 95 L.Ed. 162, reaffirmed the rule that the mere combination of a number of old parts or elements which, in combination, perform or produce no new or different function or operation than that theretofore performed or produced by them, is not patentable invention.

Devorss patent No. 2,430,709, but for certain minor differences, discloses every element of Claim 1 except the grommet. Devorss has a casing with an opening at the top, a mounting stud extending through the opening, a flange on the stud and a main resilient member supporting the flange in the casing. The resilient member is so proportioned that under normal operating conditions the flange floats out of contact with the top of the casing. To prevent the flange from striking against the top of the casing during excessive axial shock, a rubber bumper surface is provided above the flange, which hits the underside of the top of the casing. To prevent the mounting disk from hitting the top surface of the casing when the instrument is moved downwardly a rubber ring is bonded to the disk and that rubber ring engages the top of the casing upon such downward movement. Lines 41 to 45 of column 4 of the Devorss specification disclose that the stud may be covered with rubber and the opening in the top of the casing may be made sufficiently small so that the rubber covering will engage the edge of the opening in the top of the casing in case of excessive lateral displacement of the stud.

Thus it is seen that Devorss disclosed every element in his patent which is found in Claim 1 of Robinson’s patent with the exception of a grommet. However, other references cited by defendant show the prior use of a rubber grommet to accomplish the same functions as it accomplishes in the patent in suit. Such a grommet was used in Robinson’s Vibrashock Suspension (which plaintiffs have agreed belongs to the art prior to December 15, 1944 and will be discussed later herein), Nakken Patent No. 2,397,804, Pietz Patent No. 2,470,185. To add the grommet shown in these references to the Devorss casing would not, in m-y opinion, involve invention.

The application for the patent in suit was filed December 15, 1945 and the patent was granted August 12, 1947. *517 Plaintiffs made no attempt at the trial of the cause to prove their actual date of invention, consequently they are restricted to their filing date for conception of the invention. Leichsenring v. Freeman, 103 F.2d 378, 26 C.C.P.A., Patents, 1153; Alexander Milburn Co. v. Davis-Bournonville Co., 270 U.S. 390, 46 S.Ct. 324, 70 L.Ed. 651; International Seal & Knot Protector Co. v. E. J. Brooks Co., 3 Cir., 98 F.2d 647. De-vorss and Pietz were co-pending with Robinson and therefore ought not to be considered as prior art. Stelos Co. v. Hosiery Motor-Mend Corp., 2 Cir., 72 F.2d 405; United Specialties Co. v. Industrial Wire Cloth Products Corp., 6 Cir., 186 F.2d 426; Permo, Inc., v. Hudson-Ross, Inc., 7 Cir., 179 F.2d 386. See on the other hand intimations to the contrary in Detrola Radio & Television Corp. v. Hazeltine Corp., 313 U.S. 259, 265, 61 S.Ct. 948, 85 L.Ed. 1319. However, the Nakken patent may be held to be part of the prior art, even though the application for its issue was co-pending with Robinson’s application, on the ground of public sale more than one year prior to the filing date of the patent in suit. 35 U.S.C.A. § 31.
