Opinion

TUTTLE, District Judge.

This is a suit in equity, charging the Barnes Scale Company with infringement, of claims 1, 4, and 10 to 14, inclusive, of the Hem patent, No. 1,537,169. Application for this patent was filed August 15,1918, and the patent issued May 12, 1925. The evidence shows that the plaintiff Toledo Seale Company is one of the largest manufacturers of scales in the country. Notwithstanding this invention has been in their possession for nearly nine years, they have never marketed this type of scale, and it appears they have built only one model of this scale, and that for this lawsuit. Plaintiff insists that the patent has been issued less than two years, and that consequently no unfavorable results should follow its nonuse during that period. However, here is a large company, fully able to commercialize the invention, if it be a valuable one, and, under these circumstances, I feel that the fact .of its nonuse should date from the date of the application rather than the date of issue of the patent. This nonuse having existed for approximately nine years, I think it is fair to regard the Hem patent in suit as a paper patent. While nonuse does not disentitle the plaintiff' to recover, where it is clear that his patent is valid and that the defendant has infringed, on the other hand, such nonuse requires that the patent be strictly construed, and that the patentee be given nothing but that to which he is clearly entitled. Westinghouse Electric & Manufacturing Co. v. Toledo, P. C. & L. Ry. Co., 172 F. 371 (C. C. A. 6).

Nearly all counter scales of the two-bearing platform variety are provided with what is known as a check system, for keeping the platform horizontal at all times. This comprises a parallelogram, which includes the platform stem. The plaintiff contends, and the specification sets forth, that before the Hem invention it was customary to have the scale beam or multiplying lever part of the parallelogram. It is claimed that as a result wear on the fulcrum pivot of the scale beam tended to distort the parallelogram and impair the accuracy of the weighing operation. In the Hem scale the load is not supported by the check members or the parallelogram.

The claims in suit, however, do not bring out this improvement^ but are rather broad claims to the cheek members in combination with a separate load lever, and connecting means between the check system and the load lever which permits these members to swing in different ares. Some of the claims are further limited by requiring that the cheek mem7 bers swing in arcs of convexity in one direction, while the load lever swings in an are of convexity in the opposite direction. This, it is contended, permits the use of long check members running in one direction, and a long scale beam or multiplying lever running in the opposite direction, and at the same time the length of the scale base is kept down.

The defense is invalidity and noninfringement. The defendant relies particularly on the Hamilton patent, 85,816, Buoy, 99,-148, Assman, 103,541, Hansen, 967,188, Strubler, 1,213,294, and Yelter, 1,180,892. Giving the claims the ordinary meaning that their language bears, they appear to read word for word on the Hamilton patent, 85,- , 816, the Yelter patent, 1,180,892, the Assman patent, 103,541, and some of the claims are broad enough to read on Hansen, 967,188, Strubler, 1,213,294, and Buoy, 99,148. To meet this seeming anticipation, plaintiff contends that the claims should be read with the specification, and that the load lever should be read to mean the usual multiplying lever or scale beam used in the modem automatic computing scale, and also that the claims should be read as calling for a check lever system that is entirely free from the load, by reason [967]*967of the link connecting the platform and. the load lever being on the vertical center line of the platform. There are no such limitations in the claims, and I do not see what right I have to make over these claims to sustain a patent which amounts to a paper patent. At any rate, this would not help the plaintiff, for even if we grant that the claims should be read as though they were limited to a check system which is entirely relieved of the load, nevertheless the-Hamilton patent, No. 85,816, sho-tfs exactly this. The argument that I should also read these claims as calling for a modern scale beam, in order to escape Hamilton, I cannot accept, for the reason that this scale beam or multiplying lever is simply the usual lever member in the modem type scale, and there would be no invention in adapting the lever and cheek system shown in the old Hamilton patent to the modem type of scale. This is simply the natural and expected progress of the art, and not such a new combination of old elements as is patentable.

The plaintiff attacks the Hamilton .and Assman patents as being inoperative and impractical, and therefore not proper references. It contends that the Velter patent is not an automatic scale, but a recording and printing scale, and therefore not a proper reference against it.

In the evidence the plaintiff has gone quite extensively into the question of friction on the bearings, the unusually heavy pendulum, the impracticability of the indicating connection, the unsuitable markings on the dial, the friction of the pointer, etc., ’appearing in the Hamilton and the Assman patent drawings. .The witnesses for plaintiff have testified that the scales appearing in the drawings of these patents would be impractical according to the standards of to-day. However, none of the witnesses have pointed out to me wherein the lever and check systems, clearly disclosed in these patents, are impractical or inoperative in principle. The alleged defects all relate to mere details and refinements of construction. Naturally at this date these refinements are of a much higher order than they were in 1869, and it is only to be expeek ed that the modem scale should possess these while the scale of the ’60’s should be without them. The standard of to-day is, of course, much higher than at that time. This, however, does not warrant the granting of a patent to one who has incorporated such refinements in an old arrangement of elements. It seems very clear to me that all of these alleged defects are simply minor details, and could be easily remedied by a person skilled in the art, without the exercise of more than mechanical skill. Imperfections of this kind do not remove a reference from the prior art which clearly anticipates the claims as worded. Pickering v. McCullough, 104 U. S. 310, 26 L. Ed. 749; Sparks-Withington Co. v. Jay, 270 F. 449 (C. C. A. 6); Van Epps v. United Box Board & Paper Co., 143 F. 869 (C. C. A. 2); Sandusky Foundry & Machine Co. v. De Lavaud, 274 F. 607 (C. C. A. 6). It is a familiar fact that Patent Office drawings are not made to scale, and are not to be considered working drawings, and hence no defect is fatal which can be remedied by any mechanic by obvious means. Sandusky Foundry & Machine Co. v. De Lavaud, supra. I therefore do not regard these patents as inoperative in any such sense as will remove them from the prior art as anticipations. Furthermore, part' of the imperfections relied upon by plaintiff relate to parts of the reference scales which are not relied upon to meet the claims in suit. I cannot find that these prior art patents are paper patents, as alleged, for there is no evidence either way, and I see no reason why, according to the standards of their day, they were not operative to accomplish the objects intended for them.
