47 F. 48 | U.S. Circuit Court for the District of Southern New York | 1891
This is an equity action founded upon three letters patent, granted to Charles F. Brush for improvements in secondary batteries, as follows: No. 337,299, granted March 2,1886, No. 260,654, granted July 4,1882, and No. 266,090, granted October 17,1882. These patents and one other, No. 337,298, granted March 2,1886, were before this court in Brush Electric Co. v. Julien Electric Co., 41 Fed. Rep. 679. The court there decided that No. 337,298 and No. 337, 299 were for the same invention, and intimated, as the inventor and his expert apparently regarded the former as the broader patent, that the difficulty might be met by a surrender of the latter, or by a disclaimer of similar claims therein. This solution of the difficulty was thrown out as a suggestion merely, the final disposition of the patents being left till the settlement of the decree. It was not the intention of the court to decide that one of these patents was entitled to preference over the other. For the reason stated and for convenience of illustration No. 337,298 was given prominence in the discussion, but the conclusion would have been the same had the position of the patents been reversed. Upon the settlement of the decree the complainant selected No. 337,299 as the patent upon which it chose to rely, and withdrew No. 337,298 from the consideration of the court. This was done without objection by the defendant in that case. On the
The proof of infringement is substantially the same as in the BrushJulien Case. It is more complete as to the manner in which the active material is applied to the plates, hut in this respect it only emphasizes the former decision as to the non-infringement of the claim of No. 260,-654. That claim is as follows:
“The method of forming the plates of a secondary battery, consisting in forming receptacles for oxide of lead in its surface, then applying oxide of lead to the plate and within such receptacles, and afterwards subjecting the oxide of iead to pressure. ”
The claim clearly contemplates not only the treatment adopted by the defendants, but afterwards subjecting the oxide to pressure. The defendants apply the oxide to the plates and within the receptacles with a wooden trowel in the hands of the workman, and there they stop. They do not subject the oxide to pressure afterwards.
The questions arising upon the expiration of the Italian patent and as
It is thought that claims Nos. 11 and 13 of No. 337,299 — the red lead claims — are void for lack of invention. The specification, after referring to lead oxide as the active material, which is primarily and mechanically applied to the plates, proceeds:
“Peroxide is the best oxide of lead to use in the preparation of the plates; but as this is rather expensive to prepare red lead or minium may be used.”
If the record' contained nothing hut this statement the claims could not "be upheld. After the invention of a support primarily coated with mechanically applied oxide of lead, merely coating the plate with the commonest, cheapest and best known form of lead oxide did not require the exercise of the inventive faculties. Especially is this so when the patentee himself asserts that the best results can be obtained by using peroxide. It would seem that the use of red lead would at once occur to any one who had even a superficial knowledge of the art. There is no more novelty in using red lead for the coatings than there is in using cast lead for the plates. Brush Electric Co. v. Julien Electric Co., supra, 692. The following paragraph taken from defendants’ brief states with clearness and precision the views of the court upon this subject:
“The specification says that red lead is inferior to the peroxide, and we submit that no valid claim can be founded upon the use of an inferior article when it is shown that the use of the superior article is old. ”
Patent No. 337,299, at least so far as its broad claims are concerned, is not invalidated by anything contained in the Brush patents No. 260,-653 and No. 276,155. The application for the former (No. 260,653) was filed June 15, 1882, a year and two days after the .application of No. 337,299. No one can read the specification of No. 260,653 without being impressed with the fact that the inventor intended to confine the patent to a single point, namely the form of the electrodes. He expressly says so.
“This application is a division of my application designated as «Oase 1’-(337,298-9) filed June 13, 1881, in which other features of my invention are claimed. Por convenience in distinguishing this invention among others of mine in the class of secondary batteries I have denominated it * Case 1, Division A.’ ”
Again he says:
“My invention consists essentially in a secondary battery element consisting of a structure of étagdre-like form, containing in the spaces between its shelves lead in a finely divided state.”
The claim is:
“In a secondary battery, an element consisting of a structure of étaglre-like form, containing in the spaces between its shelves lead in a finely divided state, substantially as set forth.”
Mr. Brush was the first, in this country, to make the broad invention as stated above. He is entitled to the fruits of his invention. It is the policy of the law to reward him. Where the court can sec that a patentee has produced an invention of real merit it should not be unduly industrious in endeavoring to discover some statement or act of his by ■which, on technical grounds, his rights may be forfeited. It should rather be sedulous to protect him. Whether or not the improvements patented by Nos. 260,658 and 276,155 are the same as the improvements covered by some of the claims of Nos. 387,299 and 266,090 it is, perhaps, unnecessary to decide, for none of the claims in issue and infringed are so affected. It seems that in his anxiety to claim his invention in every conceivable form the patentee has involved himself in a labyrinth of descriptions and claims in which electrician and lawyer alike are quite apt to become confused. What Mr. Brush accomplished in 1879 and 1880 can be embraced in a brief, clear and concise statement. What he actually did is the test by which his patents must be judged. He is entitled to what he invented and only this. His patents can receive no broader construction because he describes his inventions with irksome prolixity and gives to the same structure a wearisome variety of names. The nomenelaturist should not seek the reward for his labors in the patent-office. A person is not entitled to a patent because he has invented a new word. The danger and impropriety of holding a number of claims which can be differentiated only by the most abstruse and metaphys
Did patents Nos. 337,299 and 266,090 expire with the Italian patent? The Italian patent was applied for July 28, 1882, sealed August 8, 1882, and was issued for a term of three years from September 30, 1882. It expired September 30, 1885, never having been prolonged, renewed or extended. No. 337,299 was granted March 2, 1886, No. 266,090, October 17,1882; both were applied for in June, 1881. Having stipulated that the Italian patent was issued for an unextended term from September 30, 1882, and that the translation appearing in the record is a correct one, the complainant is not in a position to argue that the patent was either extended as to time or limited as to its terms. Especially is this so in the absence of the Italian patent law, which is not in evidence, and of all jjroof tending to establish either extension or limitation. The difficulty with the complainant’s argument in this regard is twofold: First, there is no law, and, second, there are no facts upon which to base it.
Section 4887 of the Revised Statutes is as follows:
“No person shall be debarred from receiving a patent for his invention or discovery, nor shall any patent be declared invalid by reason of its having been first patented or caused to be patented in a foreign country, unless the same has been introduced into public use in the United States for more than two years prior to the application. But every patent granted for an invention which has been previously patented in a foreign country shall be so limited as to expire at the same time with the foreign patent, or, if there be more than one, at the same time with the one having the shortest term, and in no case shall it be in force more than seventeen years. ”
Under this section the test of identity between the foreign and the domestic patent as established by the supreme court in two recent decisions may be stated as follows: Is the principal invention in each, is the thing patented abroad, the same in all essential particulars as the thing patented here? Will the home patent be infringed by a structure made in accordance with the provisions of the foreign patent? In cases where these questions are answered in the affirmative the United States patent falls, and it will not be saved by the fact that it contains improvements not found in the foreign patent. Siemens' Adm'r v. Sellers, 123 U. S. 276, 8 Sup. Ct. Rep. 117; Commercial Manuf’g Co. v. Fairbank Canning Co., 135 U. S. 176, 10 Sup. Ct. Rep. 718. Whether the expiration of a foreign patent for an improvement only will operate to overthrow a. domestic patent for a broad invention, which contains also a claim covering the improvement, has not, apparently, been decided by the supreme court. The language of the court in Siemens' Adm'r v. Sellers, supra, is, perhaps, comprehensive enough to cover such a contingency, but this is a question which need not now be considered. In the Brush-Julien Case the court commented upon the absence of expert testimony relating to the Italian patent. No similar observation can, with propriety, be made regarding the present record. It would indicate a lamentable want of appreciation on the part of the court to ask for additional instruction and advice. Eight experts of greater or less prominence and attainments
The defendants plead the defense of forfeiture. They must prove it by a preponderance of evidence. And, yet, upon the question of the identity of the patents in question there is a sharp difference of opinion among those who are most entitled to speak upon the subject. Is there not room for the assertion that the defendants have failed to sustain the burden in this behalf? When this question was presented in the BrushJalien Case the mind of the court was in doubt, and now, having re-read the Italian patent in the light of the new testimony, it is still in doubt, but inclining more strongly to the opinion that the complainant’s contention is correct. Tlio court is not prepared to hold, therefore, that the Italian patent is for the same inventions as those covered by the two patents in question. The principal reasons which induce the court to adopt this view may be epitomized as follows:
First. The language of the Italian patent is entirely different from that of the patents in suit. The drawings are different. Some of the divisions of the Italian patent are unquestionably dissimilar and souk; concededly relate to the Planté process. The broad statement relating to the primary coating of the supports with active material is not found in the Italian patent.
Second. The inventor’s statement of his intent and purpose in taking the foreign patent and his reasons for not attempting to patent the invention of No. 337,299 abroad. This testimony is corroborated by his notes made at the time he was perfecting the inventions patented abroad. When these notes are placed side by side with corresponding portions of the Italian patent it will be seen that they are substantially similar. Mr. Brush testifies that the portion quoted describes the invention of Division D of the Italian patent.
Brush’s notes, Marsh 7, 1882.
“About three weeks ago I conceived the idea of preparing secondary battery plates by compressing partially rxidized precipitated metallic lead, in*54 the form of a fine powder, with great pressure, whereby I expect to get a solid metallic plate coherent and malleable. * * * Now, by using very finely granulated or precipitated lead, and slightly oxidizing superficially each particle, spontaneously by exposure to the air, or otherwise, and then compressing the metal, I will get a lead plate having minute seams throughout its substance filled with oxide of lead. This will very greatly facilitate the oxidation of the plate in the process of ‘ forming ’ in the battery. It will probably be found advantageous to coat a sheet of ordinary roller lead on one or both sides with this peculiar fissured metal so that the rapid oxidation in the battery will be arrested by the rolled metal when the prepared metal is all oxidized.”
*53 Division D, Italian Patent.
“In this division Ishall treata seeondary battery element, wherein, before treatment by a ‘forming’ process, either the entire body thereof,*54 or only the coating or covering of a suitable core or body, consists of a mass, composed of metallic lead and lead oxide, in an intimately mixed condition, pressed or united together into a compact and firmly coherent mass.
“In constructing this mass I take metallic lead in a pulverized, granulated, precipitated, or other finely-divided state, and allow the surface of the lead particles to become oxidized, either by exposure to the air, or by any suitable artificial oxidizing process or application. * * * I now subject the mixture to heavy pressure, hydraulic, or otherwise, whereby its particles are united and consolidated into a compact and firmly coherent mass. The mass thus formed consists of metallic lead, having minute veins of oxide of lead every where ramifying and extending through it; and these veins of lead oxide within and throughout the mass greatly facilitate the penetration of the electrical action in ‘formirg’ the plates for operative use in secondary batteries. ”
The notes of March, 1882, seem to describe the invention of Division D; they certainly do not describe the invention of No. 387,299.
Third. United States patents, other than those in question, were issued to Mr. Brush for the- divisions of the Italian patent evidently including Division D. At that time, therefore, neither the inventor nor the patent-office officials thought these inventions, or any of them, were the same as No. 337,299. Furthermore, the attention of the officials was particularly called to the foreign patents. The opinion of the United States officials seems to have been entertained also by those of Italy, France and England. Faure’s invention was well known abroad and yet the patents issued to Brush with no objection, apparently, from any source that they interfered with Faure.
Fourth. The fact that a sharp distinction is drawn in No. 337,299 between the inventor’s and Planté’s method. Mr. Brush claims his secondary battery element “as contradistinguished from a plate or element having the active material produced by the disintegrating action of electricity as in the well-known Planté process.” There is nothing of this in the Italian patent. On the other hand the inventor clearly intimates that the plates of Division D are to be formed by the Planté process.
Fifth. The vast superiority of the electrodes of the United States patents in question over those made in accordance with the directions of the Italian patent, as demonstrated by the experiments of the complainant’s experts. A careful reading of Division D in the light of the testimony
Sixth. The Italian patent is capable of- a narrow construction which differentiates it from the patents in suit. When to the statements of the patent itself is added the testimony of the inventor that he intended to limit the patent in all its branches to a coating formed by the action of the electric current and that he did not intend it to cover a coating placed on the plates mechanically before they are subjected to electrical action, there seems to be every reason why the narrower construction should be adopted.
Seventh. The fact that the element of the Italian patent is produced by heavy pressure, hydraulic or otherwise, whereby the particles of lead and lead oxide are compacted into a firmly coherent mass having minute veins of oxide of lead everywhere ramifying through it. There is nothing resembling this in the United States patents in suit.
Eighth. The “mass” described in the Italian patent is malleable and capable of being made into strips or wires and manipulated so as to form any style of element. Neither the active material of No. 337,299 nor the completed plate of that patent is capable of such treatment.
Ninth. No. 837,299 is designed to cover Mr. Brush’s inventions made in the summer of 1879 and in the summer and autumn of 1880. Brush Electric Co. v. Julien Electric Co., supra, 687; Electrical Accumulator Co. v. Julien Electric Co., supra, 129-131. Bearing this in mind it is quite clear that the discoveries of these years alone are insufficient to support the Italian patent. Something more is required. What Mr, Brush did in 1879 and 1880 is not described in the Italian patent. What he did in 1882 is described there.
The foregoing are some of the reasons which have induced the court to overrule the defense of forfeiture; in fact the more the Italian patent is studied the more settled becomes the conviction that it is not for the same invention as No. 387,299. Apply the test suggested in Commercial Manufg Co. v. Fairbank Canning Co., 135 U. S. 176, 194, 10 Sup. Ct. Nop. 718. If a person in this country, after the issue of No. 387,299, were to commence the manufacture of secondary batteries by the precise processes described in the Italian patent would the court grant an injunction to restrain their use as infringements of the claims of the United States patent? It is thought, upon the conflicting testimony here presented, an intelligent court would feel compelled to deny an injunction on the ground that infringement was not proved, or, at least,' that the question was involved in such uncertainty and doubt as to justify the court in withholding the writ. It may as well be admitted that this defense does not appeal strongly to the conscience of a court of equity. The statute creates it and in all cases where the facts are clear the statute must be implicitly followed. But no one can examine the course of judicial decision upon the subject without being impressed with the fact that the courts have sought to construe it liberally and have seldom, except in the plainest cases, permitted it to defeat a valuable patent. Believing that Mr. Brush is entitled under our law to
Assuming the inventions to be similar, the inventor has been guilty of no fault, the American public has lost no rights, and yet, under the provisions of this statute, which it is thought was never intended to apply to a case like this, a valuable monopoly is destroyed. These observations are, perhaps, only germane to the present inquiry as they tend to emphasize the suggestion already made that in dealing with a defense where, as in this case, the disaster following the inventor’s act is so out of proportion with the fault, if fault it be, the court should proceed with the utmost caution, and, where the evidence is not clear, give to the inventor the benefit of the doubt. If convinced that he did not intend to patent the invention abroad, the court should not by construction broaden the language of the foreign patent so as to destroy the domestic patent when that language is capable of a construction which permits the domestic patent to live.
The question of how to dispose of No. 337,298 is, in view of complainant’s position regarding it, more puzzling than ever. The rule which obtains in this circuit requiring a disclaimer of invalid claims as a condition of a decree has always seemed an arbitrary one. It certainly seems inequitable that the court, at nisi prius, should compel the patentee to renounce forever a claim which may be held valid upon appeal. It is possible that this rule may be modified by the circuit court of appeals. In view of this contingency and of the extraordinary and distinguishing •circumstances surrounding this case the court has concluded, if the complainant upon reflection still desires to assume the responsibility of retaining two patents for the same invention, not to require a surrender or disclaimer of No. 337,298 as a condition of a decree. It is thought, however, that pending an appeal it should be deposited with the clerk to await the further order of the court. An accounting having been waived, it follows that, on filing a disclaimer of claims 11 and 13 of patent No. 337,299 the complainant is entitled to a decree upon claims 1, 2, 3, 6, 7, and 12 of this patent, and upon claims 7 and 14 of No. 266,-090 for an injunction, but without costs.
