Opinion

OPINION AND ORDER

CLARKE, District Judge.

This is a patent infringement action. The plaintiff, Canron, Inc., a New York corporation with its principal office and place of business at West Columbia, South Carolina, has asserted that the defendant, Plasser American Corporation (Plasser), a Delaware corporation with its principal office and place of business at Chesapeake, Virginia, is infringing U.S. Patent Re. No. 29,437, which is a reissue of U.S. Patent No. 3,832,952, by manufacturing and selling machines embodying the claimed subject matter of the reissue patent.

Plasser has denied that it infringes the patent in suit and takes the position that the patent is invalid, not infringed and unenforceable, on the bases that there has been public disclosure prior to the critical date of all novel elements of the subject matter of the patent, that Plasser’s machines are materially different than the subject matter of the patent, that file wrapper estoppel applies and that Plasser has intervening rights.

Jurisdiction of this Court is based on 28 U.S.C. § 1338. The trial of the matter began on April 10, 1978. Following trial, *1012 each party submitted post-trial memorandum of law and proposed findings of fact. On May 8, 1978, the parties submitted reply memoranda.

Canron and Plasser have for some years been competitors in the design, manufacture and sale of railroad track maintenance equipment. Each party is associated with a European organization: Canron is related by ownership to a Swiss company, Matisa Materiel Industries S.A. (Matisa), and Plasser is related by ownership to one or more Austrian companies (Plasser Austria).

The subject matter of the patent in suit is the lifting and lining device used on a tamping machine. Although the mechanism is apparently compatible with other railway maintenance equipment, chief reference during trial was made to its use on tamping machines. Tamping machines with lifting and lining capacity have been in use since the early 1960’s. A tamping machine operates by engaging the track, either by the railhead or the rail base, lifting the rail vertically and compacting or tamping the ballast under the railroad ties, and lining the track horizontally. The use of tamping machines is made necessary by the constant settling of ballast, and therefore the track atop the ballast, under the loads of railway vehicles traveling over the track.

The lifting and lining mechanisms that preceded the device in the patent in suit operated largely by the use of roller clamps, mounted on a common support frame, that engaged the railhead by pivoting on an axis longitudinal with the track in an arched motion. The arched motion made it difficult to work in the area of a frog, the crossover point or switch area where two sets of tracks converge, because the arched motion required more clearance between rails than was afforded in a frog area and because the clamps could not engage the extra width and weight of a frog in a sufficiently secure manner. The area of a frog is in special need of tamping because the normal weight of traffic moving over the track is compounded in frog areas since the frog, in order to allow passage of the flanged wheels of a railway vehicle to a different track, must include gaps at points in the track where the vehicle traveling through the frog must dismount one track and remount another, resulting in greater impact at these points.

Matisa built a prototype of the patent lifting and lining device on its tamping machine, the Matisa B-13, which efficiently operated to lift and line tracks in a frog area. The mechanism operates by the use of gripping members mounted on an articulated support frame displaceable vertically and horizontally by means of hydraulic jacks. The gripping members cooperate to engage the railhead or rail base with flanged wheels, the “rail engaging means.” The flanged wheels are mounted on a carrier frame that is displaceable in the horizontal plane transversely to the track. Because the distance between the flanged wheels is less than the usual distance between the interior edges of railway tracks, the carrier frame for the flanged wheels must be moved into engagement with one rail at a time. The rail is engaged on each side by the opposing pressure from the flanged wheel on the interior of the rail-head or rail base and from the gripping members on the exterior edge. The ability of the mechanism to move into an engaging position with a single rail by the use of vertical and horizontal motions, or double straight line motion, rather than arched motions, permits the use of the patented mechanism in the close confines of a frog area.

The mechanism was patented by Matisa in Europe, and sales promotion work was begun in the late part of 1971. On November 24, 1972, using the same design as used in the Matisa B-13, Canron applied for a patent in the United States. The patent, U.S. Patent No. 3,832,952, was issued September 3, 1974. A reissue patent was applied for and the reissue patent, U.S. Patent Re. No. 29,437, the patent in suit, was issued October 11, 1977.

On the basis of all the evidence, this Court finds and concludes that plaintiff’s U.S. Patent Re. No. 29,437, which is a reissue of U.S. Patent No. 3,832,952, is invalid *1013 by virtue of having been described sufficiently in printed publications disseminated more than one year prior to the original patent application in the United States. The prior publication invalidates the contested claims of the patent in suit. Because of this finding, the Court determines that it is unnecessary to reach the issues of whether the pertinent claims of the original patent and the reissue patent are substantially dissimilar, of whether file wrapper estoppel applies, and if the patent had been found to be valid, of whether Plasser machines infringed the patent.

The statutory section governing prior publication is 35 U.S.C. § 102(b), which reads, in pertinent part:

A person shall be entitled to a patent unless—
(b) the invention was . . . described in a printed publication in this or a foreign country . . more than one year prior to the date of the application for the patent in the United States .

The parties agree that the application for a patent was first filed in the United States on November 24, 1972. Therefore, the “critical date” with respect to publication is November 24, 1971.

The burden of proof to defeat patentability by establishment of prior publication rests with Plasser, who must prove disclosure by clear and convincing evidence, The Soundscriber Corp. v. United States, 360 F.2d 954, 175 Ct.Cl. 644 (1966). There are three elements of publication: (1) the date of the publication; (2) the sufficiency of the description; and (3) the extent of the distribution.

The publication must be in the hands of the “public” prior to the critical date, November 24, 1971. The date of a mailed document for this purpose is the date it reaches the addressee. Protein Foundation, Inc. v. Brenner, 151 U.S.P.Q.
