| Cir. Ct. Del. | Jul 27, 1891
Letters patent No. 185,576, dated December 19, 1876, for an improvement in seats and backs for chairs, were issued to Reuben H. Plass, and subsequently, by sundry mesne assignments, became the property of the complainant corporation, which now sues the defendant' for an infringement. The defense is want of novelty and the consequent unpatentability of the alleged improvement. The specification states the object of the improvement to he—
“A seat or back for chairs, lounges, etc., of greater strength, durability, and rigidity, and less liable to be affected by the atmosphere than those of the ordinary character. Heretofore veneers, coated paper, metal, and other materials have been employed as substitutes for cane and leather in the manufacture of seats and backs for chairs, etc., but to a greater or less degree have failed to meet the requirements of a practical article.”
After detailing the objections to other materials, and in the making of chair seats and backs, the specification continues:
“My improved seat, which is liable to none of these objections, consists of vegetable fiber formed into a sheet which is tough, elastic, light in weight, flexible, yet possessing the requisite stiffness, extremely durable,'and of any required color.”
The specification next describes the process of making the vegetable fiber, and concludes:
*745 “The material thus prepared is termed ‘ vulcanized fiber,’and may be used in sheets or strips, solid or perforated, and applied to either the bottoms or backs of chairs, lounges, and other furniture. I do not claim vulcanized fiber, as that is not my invention. My invention relates only to the improvement of chair seats, backs, etc., and consists in the application of the material herein named in the manner set forth. 1 claim, as a new manufacture, a seat or back for chairs, lounges, etc., consisting, in whole or in part, of vulcanized fiber, — that is, vegetable fiber prepared by treating it with chloride of zinc, or its equivalent, consolidating and drying as set forth.”
Does this claim, in connection with the specification, present, a patentable invention? The provisions of the constitution, art. 1, § 8, subd. 8, is that congress shall have power to promote the progress of science and useful arts, by securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries. The beneficiary must be an inventor, and must have made a discovery. The patent law has always carried out this idea. In the act of July 8,1870, (16 St. p. 201, § 24,) the patentee was required to be a person who had “invented or discovered any-new and useful art, machine, manufacture, or combination of matter, or any new or useful improvement thereof;” and that language is reproduced in section 4886, Rev. St. So it is not enough that a thing shall be new, in the sense that in the shape or form in which it is produced it shall not have been before known, and that it shall be useful; but it must, under the constitution and the statute, amount to an invention or discovery. Thompson v. Boisselier, 114 U. S. 5 Sup. Ct. Rep. 1042.
What did Plass claim to have invented or discovered? Not the process of making vulcanized fiber, for that he expressly disclaims, but simply the substitution of that material in the place of wood, iron, or leather. The substitute purposes no new function, nor does it produce, in combination with old materials, a now result. The. application of a material that was never before used in making chairs did not require the exercise of the inventive faculty. He may have been the first person to see the adaptability of vulcanized fiber to this purpose, and to reduce it to practice; but that was nothing more than the judicious selection of a material for two of the component parts of a chair, — a choice that could have been made by any mechanic who was skilled in the art of making chairs, and had the material at hand. Before the date of Plass’ application for his patent, vulcanized fiber had been employed as a substitute for wood and for leather in the manufacture of various articles in common use, and is now extensively used in the making of traveling trunks. In the course of time, if its cost shall become cheaper, .it may still more generally take the place of other materials. But such substitution, if it amounts to nothing more than the change of one substance for another, the new performing the same function as the old, will not constitute invention or discovery, according to the legal meaning of those words as defined by repeated decisions of the supreme court. The substitution ' may produce in some respects a new" and useful article, yet, if it is not the result of a creative invention, it will not be entitled to a patent.
“It is certainly difficult to bring the case within any recognized rule of novelty by which the patent can be sustained. The use of one material instead of another in constructing a known machine is, in most cases, so obviously a matter of mere mechanical judgment, and not of invention, that it cannot be called an invention unless some new and useful result — an increase of efficiency or a decided saving in the operation — is clearly attained. Borne evidence was given to show that the wagon-reach of the plaintiff is a better reach, requiring less repair, as having greater solidity than the wooden reach. But jt fs not sufficient to bring the case out of the category of more or less excellence of-eonstructióñ. Axe helves made of hickory may be more durable and inore cheap in the end than those made of beech or pine, but the first application of hickory to the purpose would not be therefore patentable.”
In Hotchkiss v. Greenwood, 11 How. 248" court="SCOTUS" date_filed="1851-02-19" href="https://app.midpage.ai/document/hotchkiss-v-greenwood-86643?utm_source=webapp" opinion_id="86643">11 How. 248, the court decided that the substitution of porcelain for metal in making door-knobs of a particular construction was not patentable, though the new material was better adapted for the purpose, and made a better and cheaper knob; and so, also, the substitution, of wood for bone, as the basis of a bottom covered with tin, was held to be, not patentable.
In support of Plass’ patent, counsel for complainant relied on the case of Smith v. Vulcanite Co., 98 U.S. 486" court="SCOTUS" date_filed="1879-02-18" href="https://app.midpage.ai/document/united-states-v-thompson-89894?utm_source=webapp" opinion_id="89894">98 U. S. 486. There the patent was for an improvement in the manufacture of artificial sets of teeth, and consisted in substituting a plate made of vulcanizadle compound for the cement or other material formerly used. But there was something more than .a, substitution of hard rubber for gold, silver, tin, etc. The article made under the patent was a combination of materials fused together, and producing a new result, which differed in its mode of manufacture from .any other article, of its class, and was vastly better in several respects to all that had been' before known. Plass’ claim is for a plain substitution, like.the iron in the wagon-reach and the porcelain in the door-knob, .being the same in principle, and certainly displaying no higher degree .of ingenuity. The motion is denied.
