Opinion

KIRKPATRICK, District Judge

This . is a suit in equity for the infringement of three letters patent for rotary oil burners, issued to William R. Ray, and for convenience referred to in the record and in this opinion as the first, second, and third Ray patents, and numbered respectively 1,193,-819, dated August 8,1916 (filed November 30, 1914); 1,285,376 dated November 19, 1918, (filed May 8, 1916); and 1,373,149, dated March 29, 1921 .(filed September 25, 1916). The plaintiff corporation is the exclusive licensee under the Ray patents. As to all three patents, the defenses are invalidity of •the claims sued upon for anticipation and want of invention and novelty. Noninfringement was also pleaded, but was not seriously insisted upon, and it is clear that the defendant’s burner is a close imitation of the plaintiff’s patented device. The first and second Ray patents were held invalid as to all claims involved in this suit by the Circuit Court of Appeals for the Ninth Circuit in the ease of Ray et al. v. Bunting Iron Works, 4 F.(2d) 214. In considering these patents in this case, that decision must be borne in mind. The rule of comity requires this court to follow it, unless it be shown beyond doubt to be erroneous, or unless the case here presented such an entirely different record that we would be convinced that the decision of the Circuit Court of Appeals would have been otherwise upon the record as here presented.

In presenting its ease to this court, the defendant’s principal reliance was placed upon the same prior art patents (with some additional patents) on the strength of which the Circuit Court of Appeals for the Ninth circuit declared the first two Ray patents invalid. The plaintiff in rebuttal introduced a number of depositions of witnesses taken in California, designed to show a general recognition of the plaintiff’s device as an outstanding advance of great importance in the oil-burning field, and that the invention in suit solved a problem of long standing and supplied a long-felt want. The plaintiff also produced testimony supplemented by courtroom demonstrations directed to the point that the defendant’s principal prior art patents were unworkable, and therefore, since without utility, could not be considered as anticipations. This evidence, which was • not in the earlier suit, the plaintiff claims relieves us of the duty of following the decision of the Circuit Court of Appeals of another circuit. Thorough consideration of it, however, not only fails to bring us to a conclusion opposed to that reached by the Circuit Court of Appeals for the Ninth Circuit, but fails to raise any doubt of the correctness of that conclusion.

[634] Upon the issue of patentable novelty in a mechanical patent the first and most important consideration is a comparison of the patented structure with the structures of the prior art. For the purpose of assisting the court in making such comparisons the testimony of the parties themselves and of experts is usually valuable to draw the attention of the court to essential elements, to apprise the court of the physical laws governing the operation of the device, and to explain the functions of the various parts. When a comparison so made leaves the issue in doubt, resort is properly had to a number of other matters, such as the presumptions arising from the history of the proceedings in the Patent Office to obtain the patent and from its final grant, evidence'of a long-continued and unsuccessful search in the art for the results accomplished by the patent, evidence of immediate and striking commercial success, the fact that the defendant, discarding all other forms of the device, has promptly and closely imitated the plaintiff, and the like. Where, however, the want of patentable novelty is clear, from an intelligent and informed comparison of the device in issue with the prior árt, such evidence will be accorded no weight. It will not be used to create a doubt where none otherwise exists.

Taking up the first Ray patent, which comprises the features essential to the operation of all three patents, we find that these features (stated in our own language and not that of the claims) are (a) a fan or blower, in a easing, creating a strong uniform blast of air; (b) a comparatively small rapidly revolving oil eup, from the rim of which the oil is cast off in the form of a thin film by its rapid rotation; and (e) a nozzle which delivers the air blast at the rim of the eup in such manner as to atomize the oil film and direct it in an annular eloud into the line of the air.

Now, turning to the prior art, there is, of course, nothing new in using a centrifugal fan to create an air current. The plaintiff contends that an important-new feature of this instrumentality in his patent is a diaphragm, placed between the blades of the fan and the nozzle, which performs an important function in making the air current as delivered at the nozzle smooth and uniform. Whether or not this is true, the entire structure of the plaintiff’s blower and casing enclosing it is anticipated by patent No. 548,647 (1895) to Mack. Perhaps the interior fan casing used in Mack may not accurately be described as a diaphragm, but it nevertheless is an equivalent, and was obviously inserted for the same purpose. The plaintiff’s fan may be a more efficiently operated blower than Mack’s, but it certainly contains no feature of patentable novelty over it.

The idea of centrifugally discharging oil in a fine film by means of a rapidly rotating eup, into which the oil is introduced in small quantities, dates back to Cook’s patent, No. 73,506, of 1868, and oil cups for this purpose were also used in the following patents: Klein, No. 473,759 (1892); Eddy, No. 540,-650 (1895); and Feeron,- No. 613,131 (1898); and possibly others. The precise shape of the cup may, as the plaintiff contends, be of extreme importance in producing the proper kind of oil film; but that shape appears almost exactly in the Feeron patent, and in addition I am satisfied that the shaping of the cup to the form adopted by the plaintiff, while possibly an improvement, is not a patentable one over any of the prior art cups.
