Opinion

THOMAS, Circuit Judge.

By bill in equity the plaintiff charged that the defendants had jointly and severally infringed a patent, and he sought injunctive relief and damages. There was a judgment and decree for the plaintiff and the defendants appeal. Pending the appeal defendant Thomas Finn died, and his personal representative having appeared and so requested, the appeal as to him has been dismissed.

The patent, No. 1,843,748, was issued to the plaintiff February 2, 1932. The application therefor was filed May 10, 1930. The patent relates to an antiwashout device for roadways. Only claims 1, 2, 3, and 8 are involved in this suit. They read as follows:

“1. An anti-washout device for roadways or the like comprising a sheet metal member adapted to be secured in upright position, longitudinally of the road grade and having a lower portion formed to be imbedded in the road, a laterally bent flange extending along the upper edge of said member and means for retaining said member in upright position with its upper portion above the road grade to direct water longitudinally of the road.
“2. An anti-washout device for roadways comprising a long, narrow strip of sheet metal, adapted to be secured upon the surface of the road grade, longitudinally thereof, and having a bend located at the surface of the ground and imperforate portions adjacent to said bend, and means for retaining said strip in upright position to direct surface water longitudinally of the road.
“3. An anti-washout device for the shoulders of roadways or the like, comprising rigid metal strips adapted to be secured end to end along the shoulder of the road, a bend extending longitudinally of said strips at the surface of the roadway, the portions of said strip adjacent to said bend being imperforate, and the upper portion of said strips being formed to engage supporting members above the road grade, laterally bent flanges along the upper edges of said strips and supporting members adapted to be driven into the road grade for retaining said strips in upright position.
“8. An anti-washout device for roadways or the like, comprising sheet metal members adapted to be secured end to end in upright position, longitudinally of the road grade and having lower portions formed to be imbedded in the road, longitudinal bends formed in said members to be located upon the surface of said grade, imperforate, longitudinal portions of said strips immediately adjoining said bend to direct water longitudinally of the road, and means for retaining said members in upright position with said imperforate portions above the road grade.”

The defendants admitted that they make and market a device for preventing washouts on highways, but deny infringement. They allege that the patent is invalid for want of novelty in view of the state of the arts relating to roads and means of preventing washouts thereon as practiced prior to the alleged invention.

The utility of such a device as that disclosed by the patent is not questioned. In the construction of highways, particularly in a hilly country, it is necessary to construct a great many fills, sometimes as much as 40 feet deep, extending for considerable distances along the road. After the grade has been constructed, a period of a year or more is required for the earth to settle before the final hard surface can be satisfactorily applied. During this period a great deal of trouble and expense is in[550]*550curred by the frequent washing away of such newly formed grades. The patent in question was devised for the purpose of eliminating as far as possible the washouts which generally result from the water flowing over the shoulder of the grade. Prior to the use of the device covered by the patent no satisfactory method of preserving grades before stabilization by settling had been developed. The old practice was to fill the gutters eroded by the rains with earth after every washout. The testimony shows that the use of the plaintiff s device effected a saving of from $500 to $5,000 a mile on fills sloping longitudinally.

'The patented device consists of several parts. There is first a strip of metal having a bent over flange along its top edge and a longitudinal bead or corrugation located substantially centrally of the width of the strip. These sections of the metal strip, as manufactured, are approximately 6½ inches in width and 10 feet m length In order to obtain the desired length of strip on a stretch of road provision is made for joining together a plurality of such sections by means of a notch at one end of each section to receive a flange oh the adjacent end of the next section. Each section of the antiwashout strip laps over the next section about 1½ inches. The adjoining sections are held in place m an upright position by means of stakes which pass through openings m the top flange and m the'upper surface of the central corrugation. In preparation for the installation of the antiwashout strip a small trench about 1½ inches by 3 inches deep is channeled approximately 4 inches from the edge of the shoulder of the road. The strip is then placed in the trench to a depth of about 2 inches so that the central corrugation rests upon the ground. The trench is then filled and the device is protected by placing a small amount of earth against it on the outer edge of the shoulder. The device is particularly useful where there is a longitudinal slope in the road. It is intended that the water will run along the concave or convex side of the corrugation, depending upon which side of the bead faces the road, until it reaches a low place, as at the bottom of a slope, where preparation is made for its outlet. The'outlet is made by removing one section of the strip at such low point and in its stead placing a surface drain outlet. The outlets consist of four parts. Short wing strips are attached to the antiwashout strips. To the wing strips is bolted an apron or flat piece of metal attached to'which is a tapered trough. The last piece in the mechanism is a sleeve riveted to the bottom end of the drain and emptied into a flume. The flume is the means by which the water is carried from the surface drain outlet down the slope at the side of the road.

Some time after he received his letters patent the plaintiff was advised that the defendants were offering to sell to the Minnesota Highway Department an anti-washout device similar to the one patented, Individual notices of infringement were sent to the three defendants, two on July 27, 1933, and the other on September 7, 1933. Subsequent to August 7, 1933, the Minnesota State Highway Department made certain purchases from the defendants and the strips thus purchased were used on newly formed grades,

Upon the trial of the case in the lower court plaintiff introduced testimony showing. the need of an antiwashout device; how the patented device would take care of the hazards in road building for which it was intended; and the alleged infringemenk The patented device was put on the market about the middle of the year 1929. From that date until 1934 the sales including accessory drains, basins, flumes, etc., amounted to approximately $150,000. In lineal feet the sales in the state of Minnesota and surrounding states were in that period a little over 750 000.

No direct testimony on behalf of the defendants was offered. However, they m-Reduced several exhibits m evidence. Exhibit A is a drawing of a wood antiwashout device, referred to later m this opinion as the Kipp experiment.
