1. Neither the disclaimer statute, R.S. §§ 4917, 4922,
nor the rules of the common law applicable to successive
litigations concerning the same subject matter preclude
relitigation of the validity of a patent claim previously held
invalid in a suit against a different defendant. P.
297 U. S.
642.
2. The court whose jurisdiction is invoked by a suit for
infringement of a patent must determine for itself the validity of
the claims asserted, notwithstanding a prior adjudication of
invalidity of some of them, unless those issues have become
res
judicata by reason of the fact that both suits are between the
same parties or their privies. Only if it holds that the claims are
invalid may it be called upon to apply the disclaimer statute and
to decide whether the patentee, under all the circumstances
presented, has unreasonably delayed or neglected to enter a
disclaimer of the claims of whose invalidity he had notice in the
prior suit. P.
297 U. S.
645.
3. Where suit on a patent is brought in a circuit in which the
circuit court of appeals had held some of the claims invalid, the
court, in the second suit, must decide whether the issues of law
and fact in the two cases are the same, and, if they are not, it is
not bound by the earlier decision. P.

4. This Court will not answer on certificate questions covering
unstated matter lurking in the record, or which admit of different
answers dependent on circumstances not stated, academic questions,

which no basis is laid in the certificate. P.

circuit.

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, Rev.St.
§§ 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 Corp. v.
Dubilier
Page 297 U. S. 640
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,
185 U. S. 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 reissue statute, Rev.St. § 4916, as amended May 24,
1928, 35 U.S.C. § 64 so as to render both the old and the new
claims invalid,
see Altoona Public Theaters, Inc. v. American
Tri-Ergon Corp., 294 U. S. 477,
294 U. S.
490-492,
Page 297 U. S. 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 that 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
Page 297 U. S. 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 conclusive 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 adjudicata, 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,
280 U. S. 35.
The disclaimer statute was enacted to mitigate the harsh rule
[
Footnote 1] that the entire
patent was destroyed if any claim
Page 297 U. S. 643
were held invalid.
See Altoona Public Theaters, Inc. v.
American Tri-Ergon Corp., supra, 294 U. S. 490;
Ensten v. Simon, Ascher & Co., 282 U.
S. 445,
282 U. S. 452;
Hailes v. Albany Stove Co., 123 U.
S. 582,
123 U. S. 589;
Moody v. Fiske, 2 Mason, 112, 118. The statute permits the
patentee to abandon by disclaimer parts of the patent which he does
not choose to claim, and, if the disclaimer is timely and adequate,
it authorizes him to maintain suit for infringement of the
separable parts which he does choose to claim. But neither in terms
nor by implication does it deny to a patentee the right to bring a
second suit for the infringement of a claim already held to be
invalid. If such were its construction, it would deny to a patentee
the right to relitigate claims held invalid when others are held
valid or are not in issue, but would leave that right unaffected
when the entire patent is held invalid, since, in that case, there
would be nothing to disclaim.
See Winans v. New York & Erie
R. Co., 21 How. 88,
62 U. S. 103. Only
a plain legislative command would justify a construction leading to
such incongruous results.
While the contention now made is apparently for the first time
seriously argued here, this Court has several times held valid the
claims of a patent which had been held invalid by a Circuit Court
of Appeals in an earlier suit brought by the same plaintiff against
another defendant.
Expanded Metal Co. v. Bradford,
214 U. S. 366;
Diamond Rubber Co. v. Consolidated Rubber Tire Co.,
220 U. S. 428;
Abercrombie & Fitch Co.
v. Baldwin,
Page 297 U. S. 644
245 U. S. 198.
[
Footnote 2] Before the
establishment of the Circuit Court of Appeals, an adverse decision
as to the validity of a patent in one circuit appears not to have
foreclosed litigation of the same issue in another,
see Barbed
Wire Patent, 143 U. S. 275;
compare United States v. American Bell Telephone Co.,
128 U. S. 315,
128 U. S. 372.
That it does not now is implicitly recognized by the practice
established under § 240(a) of the Judicial Code and Rule 38(5)
of this Court that certiorari will not usually be granted in patent
cases unless there is a conflict in the decisions of Circuit Courts
of Appeals. We conclude that neither the rules of the common law
applicable to successive litigations concerning the same subject
matter nor the disclaimer statute precludes relitigation of the
validity of a patent claim previously held invalid in a suit
against a different defendant.
It follows that want of disclaimer of claims previously held
invalid can never be set up as a bar
in limine to the
maintenance of a second suit upon those claims, and any others of
the patent, since the patentee is entitled to invoke in that suit
the independent judgment of the court upon the validity of the
claims which have been held invalid. In advance of its decision as
to validity, that court cannot consistently hold that there is
necessity for disclaiming claims which, although previously
adjudged invalid, it may hold to be valid. The statute does not
command that a court authorized to pass upon the validity of a
claim shall accept as conclusive a previous
Page 297 U. S. 645
adjudication of invalidity of the same claim for the purpose of
ascertaining whether the disclaimer statute applies. On the
contrary, § 4922 in terms permits the patentee to "maintain a
suit . . . for the infringement of any part" of the patent "which
was
bona fide his own."
The court whose jurisdiction is invoked by such a suit must
determine for itself validity and ownership of the claims asserted,
notwithstanding a prior adjudication of invalidity of some of them,
unless those issues have become
res adjudicata by reason
of the fact that both suits are between the same parties or their
privies. If it determines that the claims previously adjudicated
are valid, there is no occasion for disclaimer. In such a case, the
intimation of the court below that the second suit must be brought
within a reasonable time is without support, for if, in that court,
the claims are upheld, there is nothing to disclaim, and the
statute does not apply. Only if it holds that the claims are
invalid may it be called upon to apply the disclaimer statute and
to decide whether the patentee, under all the circumstances
presented, has unreasonably neglected or delayed to enter a
disclaimer of the claim of whose invalidity he had notice in the
prior suit. [
Footnote 3]
The disclaimer statute is remedial, and intended for the
protection of both the patentee and the public.
See O'Reilly v.
Morse, 15 How. 62,
56 U. S. 121.
Both are protected by the construction which we adopt, and which we
think is the only admissible one. The patentee is free to preserve
some of the claims of his patent by disclaiming
Page 297 U. S. 646
others which have been held invalid, but the statute does not
force him to pay that price in order to save them. He may
relinquish the privilege of disclaimer and proceed to relitigate,
in another court, the claims which have been declared to be
invalid, but at the risk of loss in that court of the other claims
of the patent even though valid, if it likewise holds invalid the
previously adjudicated claims.
A different question is presented where the claims adjudged
invalid are abandoned, whether by a tardy disclaimer or otherwise,
and a second suit is brought to restrain infringement of other
claims,
see Ensten v. Simon, Ascher & Co., supra, or
where, in the same suit in which some claims are held invalid, the
plaintiff seeks to secure without disclaimer the benefits of a
favorable decision on other claims.
See R. Hoe & Co. v.
Goss Printing Press Co., 31 F.2d 565;
Higgin Mfg. Co. v.
Watson, 263 F. 378;
Liquid Carbonic Co. v. Gilchrist
Co., 253 F. 54;
Herman v. Youngstown Car Mfg. Co.,
191 F. 579.
We do not decide whether the purported disclaimers operate to
enlarge the claims in such fashion as to render both the old and
the new claims invalid by virtue of the reissue statute.
See
Altoona Public Theaters, Inc. v. American Tri-Ergon Corp.,
supra, 294 U. S.
490-492. That question is not presented by the petition
for certiorari. The courts below do not appear to have passed upon
it, and it may be unnecessary to decide it on the new trial. The
decree will be affirmed.
No. 590
In No. 590, the questions certified are as follows:
"1. Where certain but not all of the claims of a patent are in
suit, and all of the claims in suit are held and decreed to be
invalid pursuant to a finding and judgment to that effect of the
Circuit Court of Appeals of the circuit,
Page 297 U. S. 647
may the owner of the patent maintain a suit afterward brought
thereon in the same judicial circuit as that in which the first
cause was decided, and against a different defendant not involved
in the first suit -- the second suit being based on the claims held
in the prior suit to be invalid and on other claims of the same
patent not previously adjudicated -- where the owner of the patent
wholly failed and omitted to file any disclaimer of the claims held
in the first suit to be invalid, and where, between entry of decree
of invalidity of the claims in the first suit and the bringing of
the second suit in the same circuit, reasonable time had elapsed
for filing such disclaimer?"
"2. If question 1 is answered in the affirmative, does the
intervention of a period of approximately five years between the
final judgment in the first suit and the institution in the same
circuit of the second suit constitute delay so unreasonable as to
bar the second suit for want of disclaimer of the claims which had
been held to be invalid?"
"3. If question 2 is answered affirmatively, may the institution
or pendency of other suits in another judicial circuit or circuits
after entry of final decree in the first suit, based on claims of
the patent so held invalid and on other claims thereof not
previously adjudicated to be invalid, excuse the failure to file
disclaimer of the claims held invalid prior to instituting the
later suit in the same circuit?"
From the facts stated in the certificate, it appears that the
District Court below, upon hearing the cause, decreed the several
claims, on which the plaintiff relied to be invalid "for various
reasons, among them for neglect to file within reasonable time
disclaimers" of the claims previously held invalid by the Court of
Appeals for the same circuit. It does not appear whether the
District
Page 297 U. S. 648
Court, independently of the defense of want of disclaimer,
passed upon the validity of the claims previously adjudicated and
decided that they were invalid upon the evidence presented, or
whether it held that all inquiry as to their validity was
foreclosed by the prior adjudication.
From what we have said in our opinion in No. 388, it is manifest
that the effect rightly to be given to the failure to disclaim may
turn upon the disposition which the trial court makes of the claims
previously held invalid, and that there is no occasion for the
application of the disclaimer statute until the trial court has
itself passed on the validity of the previously adjudicated claims.
The fact that the suit was brought in the same circuit where the
Court of Appeals had previously held some of the claims invalid is
immaterial, for the court must decide whether the issues of law and
fact in the two cases are the same, and, if they are not, it is not
bound by the earlier decision.
This Court cannot be required, by certificate, to answer, and it
should not answer, questions which cover unstated matter "lurking
in the record,"
see United States v. Mayer, 235 U. S.
55,
235 U. S. 66;
Chicago, B.& Q. Ry. Co. v. Williams, 205 U.
S. 444,
205 U. S. 454;
Cross v. Evans, 167 U. S. 60;
United States v. Hall, 131 U. S. 50,
131 U. S. 52; or
questions which admit of one answer under one set of circumstances
and a different answer under another, neither of which is stated to
be the basis of the questions certified.
See White v.
Johnson, 282 U. S. 367,
282 U. S. 371;
Hallowell v. United States, 209 U.
S. 101,
209 U. S. 107;
Jewell v. Knight, 123 U. S. 426,
123 U. S. 435;
Enfield v. Jordan, 119 U. S. 680.
Moreover, it does not appear that the claims not previously
adjudicated constitute "a material and substantial part of the
thing patented, and definitely distinguishable" from the claims
held invalid, so as to admit of the
Page 297 U. S. 649
application of § 4922. We are not required to answer
academic questions, or questions which may not arise in the pending
controversy.
See White v. Johnson, supra, 282 U. S. 373;
United States v. Hall, supra; 51 U. S.
Cooper, 10 How. 54,
51 U. S. 55. For
these reasons, the first question is not answered.
The second and third questions, by their term , require an
answer only if the first is answered. In addition, the answers to
both turn upon the question whether the patentee has "unreasonably
neglected or delayed to enter a disclaimer" within the meaning of
§ 4922, which can be answered only in the light of all
relevant circumstances and the inferences to be drawn from them.
Such questions are not properly the subject of a certificate,
especially where, as here, it fails to disclose whether all the
relevant facts and circumstances have been certified.
Jewell v.
Knight, supra; Baltimore & O. R. Co. v. Interstate Commerce
Comm'n, 215 U. S. 216,
215 U. S. 221;

United States v. City Bank of
Columbus, 19 How. 385;

States v. Bailey, 9 Pet. 267,

274.
Such aid as we are able to give in answering questions as to the
scope and effect of the disclaimer statute which may be involved in
the pending cause is afforded by our opinion in No. 388.
The decree in No. 388 is affirmed.
The certificate in No. 590 is dismissed.

Footnote 1]
By § 3 of the Patent Act of 1793, 1 Stat. 318, and § 6
of the Patent Act of 1836, 5 Stat. 117, an accurate description in
writing of the invention in the patent application was prerequisite
to the award of a patent. Section 6 of the Act of 1793, and §
15 of the Act of 1836, authorized the defendant in a patent suit,
by way of defense, to prove that the specification of the patent
"contains more than is necessary to produce the described effect, .
. . or that the thing, thus secured by patent, was not originally
discovered by the patentee." By the Act of 1832, 4 Stat. 559, it
was provided that, whenever any patent shall be invalid by reason
of failure to comply with the requirements of § 3 of the Act
of 1793, it should be lawful to grant a new patent to the patentee
for his invention upon surrender of the old patent and compliance
with § 3 of the Act of 1793. Section 13 of the Act of 1836
similarly authorized the new patent to issue "in accordance with
the patentee's corrected description and specification." Section 7
of the Act of 1837, 5 Stat. 191, 193, carried into R.S. §
4917, first permitted the patentee to preserve the valid part of
his original patent by disclaimer.

We do not now determine the effect of the disclaimer statute
when the second suit, either from choice or necessity, is confined
to claims held valid or not adjudicated in the earlier action.
Whether the claims previously held invalid should be deemed
abandoned and properly subject to disclaimer would depend upon
special circumstances and involve questions not presented in the
present suit.
