The decision of the Commissioner of Patents, granting an
application for a patent a former application for which has been
rejected or withdrawn is not conclusive upon the question of
abandonment of the invention in a suit brought for the infringement
of the patent.
An inventor whose application for a patent has been rejected by
the Patent Office and withdrawn by him and who, without substantial
reason or excuse,
Page 118 U. S. 23
omits for eight years to reinstate or renew it, during which
time many patents embodying the substance of the invention are
granted to other persons, must be held to have abandoned the
invention.
Bill in equity for the infringement of letters patent. The case
is stated in the opinion of the Court.
MR. JUSTICE GRAY delivered the opinion of the Court.
This was a bill in equity for the infringement of letters patent
granted May 7, 1872, to John W. Cochran, for an improvement in
breechloading firearms, of which one of the plaintiffs was the
owner and the others were the exclusive licensees. The answer
denied that Cochran was the original inventor, and alleged that his
application, upon which the letters patent were issued, was made
and filed in the Patent Office on May 6, 1868; that for more than
two years before that date the thing patented had been in public
use and on sale with his consent and allowance, and that long prior
to that date the invention had been abandoned by him to the public.
A general replication was filed, and evidence taken, by which the
material facts appeared to be as follows:
On January 10, 1859, Cochran filed an application for a patent
for this invention, which on February 8, 1859, was rejected by the
Commissioner of Patents for want of novelty, and on February 20,
1860, was withdrawn by Cochran, and $20 refunded to him, at his
request, agreeably to the Act of July 4, 1836, c. 357, § 7, 5 Stat.
120.
At various dates from November 19, 1861, to February 11, 1868,
eighteen patents were granted to other persons for the same
devices, or their equivalents, and the defendants bought some of
those patents, and afterwards manufactured firearms under them.
On May 6, 1868, Cochran filed a new application, which was
rejected by the examiners, on the ground of abandonment. On
Page 118 U. S. 24
June 9, 1869, Mr. Commissioner Fisher, on appeal, affirmed their
decision. His opinion is published in the Decisions of the
Commissioner of Patents for 1869, p. 30. On appeal to the Supreme
Court of the District of Columbia his decision was reversed. On
July 7, 1870, he rejected the application; but on December 5, 1870,
Cochran filed a formal renewal of his application, under the Act of
July 8, 1870, c. 230, § 35, and on May 7, 1872, the patent sued on
was granted to him by Mr. Fisher's successor.
During the time between the applications of 1859 and of 1868,
Cochran applied for and obtained twenty-two other patents, nine of
them for improvements in breechloading firearms, some of which he
sold for considerable sums. He was poor and in debt, but upon the
whole evidence it is quite clear that his delay in renewing the
application of 1859 was not owing to want of means, but to his
regarding this patent as of less value than the others.
The circuit court was of opinion that the invention had been
abandoned before May, 1868, and therefore entered a decree
dismissing the bill. 14 Blatchford 94; 2 Banning & Arden 493.
From that decree this appeal is taken.
The renewal of Cochran's application on December 5, 1870, was
under the provision of the Act of July 8, 1870, c. 230, § 35, which
allowed any inventor whose application for a patent had been
rejected or withdrawn before the passage of that act, to renew it
within six months after its passage and provided that upon the
hearing of such renewed application, abandonment should be
considered as a question of fact. 16 Stat. 202.
The rules of law which must govern this case are clearly
established by the judgment of this court in
Planing Machine
Co. v. Keith, 101 U. S. 479. The
decision of the Commissioner in favor of the applicant upon the
question whether the invention has been abandoned is not
conclusive, but may be contested and reviewed in a suit brought for
the infringement of the patent. There may be an abandonment of an
invention to the public as well after an application has been
rejected or withdrawn as before any application is made. Such
abandonment
Page 118 U. S. 25
may be proved either by express declarations of an intention to
abandon, or by conduct inconsistent with any other conclusion. An
inventor whose application for a patent has been rejected and who,
without substantial reason or excuse, omits for many years to take
any step to reinstate or renew it, must be held to have acquiesced
in its rejection, and to have abandoned any intention of further
prosecuting his claim.
In the case at bar, the first application was both rejected by
the commissioner and withdrawn by the applicant; and the question
presented is well put in the opinion of Mr. Commissioner Fisher,
above referred to:
"Can an inventor withdraw his application, make no effort to
renew it for eight years, during which time the subject matter of
the invention has been incorporated into the substance of many
other subsequent inventions, and then file a new application and
obtain a patent, which, to support the novelty of the invention,
shall relate back to the first application?"
We concur with him and with the circuit court in deciding that
an inventor cannot do this.
Decree affirmed.
