88 U.S. 112 (____)
21 Wall. 112
SMITH
v.
NICHOLS.
Supreme Court of United States.

*115 Mr. Charles Mason, for the appellant; Messrs. George Gifford and Benjamin Dean, contra.
Mr. Justice SWAYNE stated the case more particularly, and delivered the opinion of the court.
The bill is founded upon a patent, and was filed by the appellant. It charges infringement. Its object and prayer are to have the defendant enjoined from infringing further, and required to account for the profits he has wrongfully made.
The original patent was issued to the complainant on the 5th of April, 1853. On the 28th of March, 1867, it was extended for seven years. It was subsequently reissued in three divisions, as follows: Reissue No. 2656, June 18th, 1867, division A, for improvements in weaving; reissue No. 3014, June 20th, 1868, division B, for improvements in woven fabrics and reissue No. 2844, January 14th, 1868, division C, for improvements in looms for weaving. Division B is the only one to be considered in this case.
In the specification the loom and process for weaving corded elastic india-rubber fabrics are described, and the excellence of such fabrics so woven, and the points in which they are superior to fabrics not so woven, are pointed out and insisted upon. The claim is thus expressed:
"What, therefore, I claim as my invention in this subdivison of my patent is 
"The corded fabric, substantially as hereinbefore described, in which the cords are elastic and held between the upper and under weft threads, and separated from each other by the interweaving of the upper and under weft threads with the warp threads in the spaces between the cords, and only there, substantially as above shown."
This bill was filed on the 19th of November, 1868.
*116 On the 22d of January, 1870, the complainant filed a disclaimer of any fabric in which the warp and weft threads are so interwoven between the elastic cords as to form strips of shirred cloth between and by the contraction of the elastic cords  the warp threads in his improved fabric being, as he declared, only interwoven with the weft threads  for the purpose of binding them tightly around the elastic cords. On the 27th of May, 1872, he filed a disclaimer of "any fabric in which the weft threads are so interwoven with the warp threads that the former are not brought halfway around each of said cords, so as to gripe them in such a way as not to permit said elastic cords to slip between said weft threads, in case said cords are cut crosswise or bias."
The substance of the specification as limited by the disclaimers may be thus summarized: The elastic cords are placed side by side, equidistant from each other. They are stretched several times their normal length. In the spaces between the cords warp threads are placed parallel with the cords, and of less size. The cords remain stationary. The warp threads are thrown open by the machinery of the loom. Every alternate thread is thrown upwards and the intermediate one downwards. What is termed a "shed" is thus formed above the cords and one under them. Through each of these sheds a weft thread is passed by means of a shuttle. One of the shuttles is thus passed above and the other below all the rubber cords. After both the weft threads have been driven home by the lathe, the position of the warp threads is inverted by the treadle. Sheds are thus formed on the opposite sides of the cords. Weft threads are then again passed across the fabric. This process is continued until the weaving is completed.
The weft threads form the only covering on the upper and under side of the cords. When their tension ceases after the weaving is done the cords contract in length and increase proportionately in thickness. The weft threads are necessarily brought into proximity with each other. They partially imbed themselves in the cords, hold them firmly, and prevent them from slipping back, if cut anywhere, while *117 at the tension which subsisted when the weaving took place. So the weft threads cling tightly to the rubber cords in every degree of tension to which they may be subjected. Each of the former grasps firmly each of the latter half round.
The points with respect to this litigation, which the complainant claims as covered by his patent, we understand, are that fewer warp threads are used, that the tightness of the weaving is greater, that the rubber cords in all stages of tension are more firmly and effectually held in his fabric than in any which preceded it,  and especially, the manner in which the weft threads, one above and the other below, grasp each of the rubber cords half round.
It is objected that the disclaimers having been made after the filing of the complainant's bill, cannot avail him in this case. Upon a fair construction of the seventh and ninth sections of the act of 1837, we think they could be made as well after as before the commencement of the suit. It would, in such case, be the duty of the court to see that the defendant was not injuriously surprised, and to impose such terms as right and justice might require. The question of unreasonable delay would be open for the consideration of the court, and the complainant could recover no costs. We see no reason for turning a party out of court to renew the litigation after filing the disclaimer, thus subjecting both parties to the delay and expense which must necessarily follow, and without any benefit to either. We cannot believe such to have been the intention of Congress.[*]
The defence mainly relied upon is want of novelty; in other words, the prior public use of the things patented.
The counsel for the appellant admits expressly that an elastic fabric with silk on one side and cotton on the other, one woven with two shuttles, one woven with stationary elastic cords, and one with elastic cords covered above and below solely by weft threads, were known and in public use by themselves separately before the alleged invention of the *118 complainant. It is also admitted that suspender webbing of different kinds, some provided with elastic cords having strips of cloth interwoven between them, and another class without the strips of cloth and similar to the complainant's, "except that the weft threads in pairs were not made to grasp the elastic cords in the manner described in the complainant's specification," also in like manner preceded his invention. The proof to the same effect, less the exception named, is voluminous and conclusive. It is unnecessary particularly to refer to it. The testimony is equally full as to webbing for shoe gores. That, made in the same way as the suspender webbing, also came into public use and was largely sold at as early a period.
The testimony of Hotchkiss establishes conclusively that  also prior to the defendant's invention  he made and sold suspender webbing with what were called binding warps between the rubber warps, with weft threads which "went over all the rubber warps, and under all the rubber warps," and that the fabric was woven while the rubber cords were in a state of tension. He says further, that he had never known suspender webbing made by American manufacturers in any other way. There is a large mass of other testimony relative to the case in this aspect, but it is deemed unnecessary to pursue the subject further.
The evidence before us leaves to the complainant none of the particulars claimed as of his invention, except perhaps greater tightness of the weaving, a firmer grasping of the elastic cords by the weft threads half round, above and below, and greater beauty and value of the fabric. The entire ground of the controversy between the parties is reduced to this narrow isthmus, and the question presented for our determination is one rather of law than of fact.
A patentable invention is a mental result. It must be new and shown to be of practical utility. Everything within the domain of the conception belongs to him who conceived it. The machine, process, or product is but its material reflex and embodiment. A new idea may be ingrafted upon an old invention, be distinct from the conception which *119 preceded it, and be an improvement. In such case it is patentable. The prior patentee cannot use it without the consent of the improver, and the latter cannot use the original invention without the consent of the former. But a mere carrying forward or new or more extended application of the original thought, a change only in form, proportions, or degree, the substitution of equivalents, doing substantially the same thing in the same way by substantially the same means with better results, is not such invention as will sustain a patent. These rules apply alike, whether what preceded was covered by a patent or rested only in public knowledge and use. In neither case can there be an invasion of such domain and an appropriation of anything found there. In one case everything belongs to the prior patentee, in the other, to the public at large.
The question before us must be considered in the light of these rules. All the particulars claimed by the complainant, if conceded to be his, are within the category of degree. Many textile fabrics, especially those of cotton and wool, are constantly improved. Sometimes the improvement is due to the skill of the workmen, and sometimes to the perfection of the machinery employed. The results are higher finish, greater beauty of surface, and increased commercial value. A patent for the better fabric in such cases would, we apprehend, be unprecedented. The patent in the present case rests upon no other or better foundation.
DECREE AFFIRMED.
