In a proceeding under R.S. § 4915, 35 U.S.C. § 63, the District
Court found against petitioner on an issue of priority of
invention, and dismissed the bill without considering the validity

MR. JUSTICE BLACK delivered the opinion of the Court.
Claiming he was the original and sole inventor of a mechanical
device, the respondent Kepner asked the United States Patent Office
for a patent. Later, the petitioner Sanford filed a similar
application making the same claim. As authorized by R.S. § 4904, 35
U.S.C. § 52, the Commissioner of Patents directed a board of
interference examiners to hold hearings and determine the
Page 344 U. S. 14
dispute over priority of invention -- which of the two first
used the device. The Board decided for respondent Kepner. Sanford's
application for patent was accordingly refused. As authorized by
R.S. § 4915, 35 U.S.C. § 63, Sanford brought this bill in equity
praying that he be adjudged inventor of the device and entitled to
a patent. Sanford also prayed that Kepner's claims be adjudged
unpatentable, charging that many previous patents had been granted
on Kepner's device, some of which had expired. Agreeing with the
Board of Interference Examiners, the District Court found against
Sanford on the issue of prior use. Since this was enough to justify
refusal to issue Sanford a patent, the District Court declined to
go further and consider Kepner's claim to a patent. Accordingly,
Sanford's bill was dismissed. 99 F. Supp. 221. Agreeing with the
District Court, the Court of Appeals affirmed. 195 F.2d 387. The
circuits have different views concerning the duty of district
courts to consider and adjudicate questions of invention and
patentability when parties urge them in R.S. § 4915 proceedings.
* To settle these
differences, we granted certiorari. 343 U.S. 976.
So far as relevant to the precise question here, R.S. § 4915, as
now contained in 35 U.S.C. § 63, reads:
". . . whenever any applicant is dissatisfied with the decision
of the board of interference examiners, the applicant . . . may
have remedy by bill in equity . . . , and the court . . . may
adjudge that such applicant is entitled, according to law, to
receive a patent for his invention. . . . And such
Page 344 U. S. 15
adjudication, if it be in favor of the right of the applicant,
shall authorize the commissioner to issue such patent on the
applicant filing in the Patent Office a copy of the adjudication
and otherwise complying with the requirements of law."
The obvious purpose of the quoted part of R.S. § 4915 is to give
a judicial remedy to an applicant who has been finally denied a
patent because of a Patent Office decision against him and in favor
of his adversary on the question of priority. When the trial court
decides this factual issue of priority against him, and thus
affirms the refusal of the patent by the Patent Office, he has
obtained the full remedy the statute gives him. Only if he wins on
priority may he proceed. In that event, the statute says, the court
may proceed to "adjudge that such applicant is entitled, according
to law, to receive a patent for his invention. . . ." So adjudging,
it may authorize issuance of the patent. But judicial authorization
of issuance implies judicial sanction of patentability, and, for
this reason, this Court has said,
"It necessarily follows that no adjudication can be made in
favor of the applicant unless the alleged invention for which a
patent is sought is a patentable invention."
Hill v. Wooster, 132 U. S. 693,
132 U. S. 698.
The principle of the
Hill case is that the court must
decide whether claims show patentable inventions before authorizing
the Commissioner to issue a patent. No part of its holding or
wording, nor of that in
Hoover Co. v. Coe, 325 U. S.
79, requires us to say R.S. § 4915 compels a district
court to adjudicate patentability at the instance of one whose
claim is found to be groundless. Sanford's claim was found to be
groundless.
It is unlikely that this equity proceeding would develop a full
investigation of validity. There would be no attack on the patent
comparable to that of an infringement action. Here, the very person
who claimed an invention
Page 344 U. S. 16
now asks to prove that Kepner's similar device was no invention
at all, because of patents issued long before either party made
claim for his discovery. There is no real issue of invention
between the parties here, and we see no reason to read into the
statute a district court's compulsory duty to adjudicate
validity.
Affirmed.
