Coffin v. Ogden

stated the case, recited the evidence, and delivered the opinion of the court.

The appellant was the complainant in the court below, and filed this bill to enjoin the defendants from infringing the. *121 patent upon which the bill is founded. The patent is for a door lock with a latch reversible, so that the lock can be applied to doors opening either, to the right or the left hand. It was granted originally on the 11th of June, 1861, to Charles 11. Miller, assignee of William S. Xirkham, and reissued to Miller on the 27th of January, 1863. On the 10th of June, 1864, Miller assigned the entire patent to the com -' plainapt. No question is raised as to the complainant’s title, nor as to the alleged infringement by the defendants. The answer alleges that the thing patented, or a material and substantial part thereof, had been, prior to the supposed invention thereof by Xirkham, known and used by divers persons in the United' States, and that among them were Barthol Erbe, residing at Birmingham, near Pittsburg, and Andrew Patterson, Henry Masta, and Bernard Brossi, residing at Pittsburg, and that all these persons had Ruch knowledge at Pittsburg. The appellees insist that Erbe was the prior inventor, and that this priority.is fatal to the patent. This proposition, in its aspects of fact and of law, is the only one which we have found it necessary to consider.

Xirkham made his invention in March, 1861. This is clearly shown by the testimony, and there is no controversy between the parties on the subject.

It is equally clear that Erbe made his invention not later' than January 1st, 1861. This was not controverted by the counsel for the appellant; but it was insisted that the facts touching that invention were not áuch as to make it available to the appellees, as against the later invention of Xirkham and the pateut'founded upon it. This renders it necessary to examine carefully the testimony upon the subject.

M'be’s deposition was taken at Pittsburg upon interrogatories agreed upon by the parties and sent out from New York. He made the lock marked H. E. (It is the exhibit of the appellees, so marked.) He made the first lock like it in the latter part of the year 1860. He made three such before he made the exhibit locdc The first he gave to Jones, Wallingford & Co. The second he sent to Washington, when he applied for a patent. The third he made for a *122 friend of Jones. He thinks the lock he gave to Jones, Wallingford & Co. was applied to a door, but is not certain.

Brossi. In 1860 he was engaged in lockmaking for the Jones and Nimmick Manufacturing Company. He had known Erbe about seventeen years. In 1860 Erbe was foreman in the lock shop of Jones, Wallingford & Co., at Pitts-burg. In that year, and before the 1st of January, 1861, he went to Erbe’s house. Erbe there showed him a lock, and how it worked, so that it could be used right or left. He says: “He (Erbe) showed me the follower made in two pieces. One piece you take out when you take the knob aw7ay. The other part — the main part of the follower— slides forward, in the case of the lock with the latch, so you can take the square part of the latch and turn it around left or right, whichever way a person wants to.” He had then been a lockmaker eight years. He examined the lock carefully. He had never seen a reversible lock before. He has examined the exhibit lock. It is the same in construction. The only difference is, that the original lock was made of rough wrought iron. It was a complete lock, and capable of working. Erbe thought it a great.thing. Erbe showed him the lock twice afterwards at Jones, Wallingford & Co’s. He saw such a lock attached to the office door there and working, but don’t know whether it was the first lock made or one made afterwards.

Mctsia. In 1860 he was a patternmaker for Jones, Wallingford & Co. Had known Erbe fourteen or fifteen years. Erbe showed him his improvement in reversible locks New Year’s day, 1861. He examined the lock with the case open. “You had to pull out the spindle, and the hub was fitted so that it would slide between the spi'ndle and the plate and let the latch forward.” . . . “ The whole hub was made of three pieces. One part Avas solid to the spindle or hub shanks, and then the hub that slides between the plate and case, and a washer at the other side of the spindle.” “ There is not a particle of difference between the exhibit and the .original lock. It is all the same.” He identifies the time by the facts that he commenced building a house in 1861, *123 and that year is marked on the water conductor under the roof.

Patterson. Until recently he was a manufacturer of locks and other small hardware. In the year 1860 he was the superintendent of the lock factory of Jones, Wallingford & Co., and their successors in Pittsburg. He had known Erbe since 1856. About the 1st of January, 1861, Erbe showed him an improved reversible lock of his invention like the exhibit lock. The improvement “ consisted in constructing the hub or follower, so that when the spindle was withdrawn, the hub would slide forward between the cases so that the head of the latch would protrude b.eyoud the face of the lock, so as to permit'its reversal from right to left; the latch-head being connected with the yoke by a swivel joint, so that it might be reversed. . , . It was our uniform practice to put our new locks on the doors about the office to test them, and I believe that one was put on ; but at this distance of time I cannot say positively that it was.”

There is no proof that Erbe made any locks according to his invention here in question but those mentioned in his testimony. He applied for a patent in 1864, and failed to get it. Why, is not disclosed in the record.

The appellants called no witnesses at Pittsburg or elsewhere to contradict or impeach those for the appellees. Brossi was subjected to a rigorous cross-examination, but, in our judgment, it in nowise diminishes the effect of his testimony in chief. The counsel for the appellants asked with emphasis, in the argument here, why the defendants had not called Jones, of the firm of Jones, Wallingford & Co. ? The question was well retorted, why was he not called by the other side ? He does not appear in a favorable light. He prevented Erbe, who was in his employ, from' going to New York to testify in behalf of the defendants, and avowed a determination to prevent, if it were possible, their obtaining the testimony of Brossi, Masta, and Patterson. It is difficult not to regard him with a feeling akin to that which attends the presumptions in odium spoliatoris. We entertain no doubt that the testimony of all these witnesses is true in *124 every particular, including the statement of Brossi as to putting the lock on the door. If that were false, doubtless Jones would have'been called to gainsay it. His hostility to the defendants is a sufficient reason for their not calling him for any purpose.

The case arose while the Patent Act of 1836 was in force, and must be decided under its provisions. The sixth sec-' tion of that act requires that to entitle the applicant to a patent, his invention or discovery must be one “ not known or used by others before his invention or discovery thereof.” The fifteenth section allowed a party sued for infringement to prove, among other defences, that the patentee “ivas not the original and first inventor of the thing patented, or of a substantial and material part thereof claimed to be now.”

The whole act is to be .taken together and construed in the light of the context'. The meaning of these sections most be sought in the import of their language, and in the object gnd policy of the legislature in enacting them. * The invention or. discovery relied upon as a defence, must have béen complete, and'capable of producing the result sought-to be accomplished ;• and this -must be shown by the defendant. The burden of proof rests upon him, and every reasonable doubt should be resolved against him. If the thing were embryotie or' inchoate; if it rested in speculation or experiment; if the process pursued for its development had failed to reach the point of consummation, it cannot avail to defeat a patent founded upon a discovery or invention which was completed, while in the other case there Avas only progress, however near that progress may have approximated to the end in view. The law requires not conjecture, but certainty. If the question relate to a machine, the conception must have been clothed in substantial forms Avhich demonstrate at once its practical efficacy and utility. † The prior knowledge and use by a single person is sufficient. *125 The number is immaterial. * Until his work is done, the inventor has given nothing to the public. In Gayler v. Wilder the views of this court upon the subject were thus expressed: “ We do not understand the Circuit Court to have said that the omission of Conner to try his safe by the proper tests would deprive it of its priority; nor his omission to bring it into public use. He might have omitted both, and also abandoned its use and been ignorant of the extent of its value; yet if it was the same with Fitzgerald’s, the latter would not, upon such grounds, be entitled to a patent; provided Conner’s safe and its mode of construction were still in the memory of Conner before they were recalled by Fitzgerald’s patent.” Whether the proposition expressed by the proviso in' the last sentence is a sound one, it is not necessary in this case to consider.

Here it is abundantly proved that the lock originally made by Erbe “was complete and capable of working.”' The priority of Erbe’s invention is clearly shown. It was known at the time to at least five persons, including .Jones, and probably to many others in the shop where Erbe worked; and t,he lock was put in use, being applied to a door, as proved by Brossi. It was thus tested and shown to be successful. These facts bring the case made by the appellees within the severest legal tests which cau be applied to them. The defence relied upon is fully made out.
