Opinion

Mr. Justice Stone

delivered the opinion of' the Court.

In No. 388 certiorari was granted to resolve questions as to the scope and effect of the disclaimer statute, R. S. §§ 4917, 4922, 35 U. S. C. §§ 65, 71, raised in a suit brought to enjoin infringement of several patent claims, some of which had previously been held invalid in an infringement suit in another circuit against different defendants.

In No. 590 like questions have been argued upon .certificate to this Court, under § 239 of the Judicial Code, of the Court of Appeals for the Seventh Circuit.

No. 388.

Respondents in No. 388,- before bringing the present .suit, had sued in a district court in the third circuit to restrain infringement of Claim 9 of Patent No. 1,635,117, July 5, 1927, to Dunmore, for a signal receiving system, and of Claims 3 and 14 of Patent No. 1,455,141, May 15, 1923, to Lowell and Dunmore, for a radio receiving apparatus. Each claim was held invalid by the Court of Appeals for the Third Circuit, Radio Corporation v. Du *640 bilier Condenser Corp., 59 F. (2d) 305, 309, and petitions to this Court for certiorari were denied, 287 U. S. 648, 650. More than eight months after the denial, of certiorari respondents filed, in the Patent Office, purported disclaimers of each of the claims thus held invalid, and more than a month later began the present suit in the district court for Maryland to restrain infringement of the same claims and other claims of the same patents not previously adjudicated. A motion to dismiss the suits as to both patents for unreasonable delay in filing disclaimers of the claims previously held invalid, and because the disclaimers were inadequate, was granted by the District Court upon the latter ground.

The Court of Appeals for the Fourth Circuit reversed and ordered a new trial, 77 F. (2d) 556,. holding that respondents were not barred from maintaining the second suit, against different defendants, for infringement of 'the claims previously held invalid and that the disclaimer of those claims was not' prerequisite to maintenance of the suit upon the claims not previously adjudicated. It intimated that the second suit could not be maintained unless brought without unreasonable delay, but it concluded that it could not say that there had been unreasonable delay in the present case.

Whether the respondents’ disclaimers are merely an attempted formal alteration of the claims so as to conform them more precisely to the specifications without changing their substance or conceding their invalidity, see Carnegie Steel Co. v. Cambria Iron Co., 185 U. S. 403, 435, or whether they are in effect such alterations of the substance of the claims as to bring them within the requirements and limitations of the re-issue statute, R. S. § 4916, 35 U. S. C. 54, so as to render both the old and the new claims invalid, see Altoona Publix Theatres, Inc. v. American Tri-Ergon Corp., 294 U. S. 477, 490-492, *641 are questions which have been much argued here and below. In reaching its decision the Court of Appeals assumed, as we shall assume without deciding, that the disclaimers were inadequate because they failed to concede invalidity of the adjudicated claims. It concluded that if the same decision were reached, as to the validity of the claims previously adjudicated, as in the Third Circuit, the respondents’ suit must fail both as to them and as to all the other claims, “even though some of them may be good. For it would then be established that the owner of the patent had failed to file disclaimers within a reasonable time after notice of the invalidity of some of the claims had been brought home to him.” 77 F. (2d) 556, 561.

Revised Statutes, § 4917, provides that “Whenever, through inadvertence, accident, or mistake, ... a patentee has claimed more than that of which he was the original or first inventor, . . . his patent shall be valid 'for all that part which is truly and justly his own, . . .” and authorizes him to file in the Patent Office a written disclaimer of “such parts of the thing patented as he shall not choose to claim.” Revised Statutes § 4922 authorizes a patentee who has claimed more than that of which he was the inventor, to maintain a suit for the infringement of “any part” of the patent “which was bona fide his own, if it is a material and substantial part of the thing patented, and definitely distinguishable from the parts claimed without right, notwithstanding the specifications may embrace more than that of which the patentee was the first.-inventor or discoverer,” but with the proviso that “no patentee shall be entitled to the benefits of this section if he has unreasonably neglected or delayed to enter a disclaimer.”

Petitioners contend that if any claim of a patent is adjudged invalid no further suit can be maintained upon it, or upon other claims of the patent without disclaimer *642 of the claims previously held invalid. This contention is predicated upon the rule that, save for the disclaimer statute, adjudication of invalidity of any claim of a patent renders the entire patent void, and upon the .assumption that by force of the statute, if not without it, an adverse decision on any claim is final and conclusivo, as to its invalidity, in any court, except as modified upon an appellate review. If this view be accepted, it follows that the right .to maintain suit for infringement of the separable claims of a patent which already have been held valid, or have not been adjudicated, may alone be saved by disclaimer of all claims held invalid, within a reasonable time after their adjudication; the patentee may not contest again the validity of the claims held invalid and only by abandoning them by- timely disclaimer may he litigate other claims.

Neither reason nor authority supports the contention that an adjudication adverse to any or all the claims of a patent precludes another suit upon the same claims against a different defendant. While the earlier decision may by comity be given great weight in a later litigation and thus persuade the court to render a like decree, it is not res adjudicatá and may not be pleaded as a defense.See Mast, Foos & Co. v. Stover Mfg. Co., 177 U. S. 485; Sanitary Refrigerator Co. v. Winters, 280 U. S. 30, 35. The disclaimer statute was enacted to mitigate the harsh rule 1 that the entire patent was destroyed if any claim *643 were held invalid. See Altoona Publix Theatres, Inc. v. American Tri-Ergon Corp., supra, 490; Ensten v. Simon, Ascher & Co., 282 U. S. 445, 452; Hailes v. Albany Stove Co.,
