1. G wrote to the Navy Department, with respect to his invention
for drying materials, that, in consideration of the Department's
building a testing apparatus at its own expense, he gave it the
option of using the method, if it found it to its advantage, by
paying so much for each pound of material so dried. The Department
accepted the proposition, saying that it had ordered an
experimental apparatus on G's plan, which would be tested and, if
it worked satisfactorily to the Bureau of Ordnance, would pay him
as proposed. After the test, the Bureau notified G that the test
proved unsatisfactory and was abandoned.
Held:
(a) Not a contract that the Department would use the method, but
an option, or at most a conditional obligation subject to be
terminated by the Department when the test proved unsatisfactory P.

receiving notice from the bureau that the relations between them

Appeal from a judgment of the Court of Claims.
MR. JUSTICE McKENNA delivered the opinion of the Court.
Appeal from judgment of the Court of Claims dismissing petition
of appellant in which she prayed judgment against the United States
for the sum of $236,750.
A summary of the allegations of the petition is as follows:
The government was engaged in the manufacture of smokeless
powder at its station at Indian Head, Maryland.
Gathmann had under consideration, with a view to the application
for patents, methods of drying the materials of the powder, and in
consequence of conversations with the Chief of the Bureau of
Ordnance of the Navy Department, he made to the bureau the
following proposition:
1839 Vernon Ave., N.W.
Washington, D.C. March 24, 1903
"Sir: The undersigned has made an invention, 'method of drying
materials,' for which patent has been filed Feb. 9, 1903, Series
No. 142653."
"Now, in consideration of the Navy Department's building an
apparatus for testing this method without expense to me, I hereby
give the Navy Department the option of using my method of drying
materials, if they find it to their advantage, by paying to me, my
heirs, or my legal
Page 260 U. S. 669
representatives, $0.01 (one cent) for each pound of material
dried by my method."
"Very respectfully,"
LOUIS GATHMANN
"Admiral O'Neil"
"Chief of Bureau of Ordnance"
He delivered with the proposition a plan or drawing for an
experimental apparatus.
To the proposition, the Chief of the Bureau of Ordnance replied
as follows:
Address Bureau of Ordnance, Navy Department,
and refer to No. 3585
Washington, D.C. March 26, 1903.
"Sir: Referring to your communication of March 24th, 1903,
offering the Navy Department the option of using your method of
drying materials, on payment of one cent per pound on materials so
dried:"
"The Bureau has to inform you that it accepts your proposition,
and has ordered one experimental apparatus for drying smokeless
powder, constructed in accordance with plan submitted by you. This
apparatus will be tested without expense to you, and, if it works
satisfactorily to the Bureau, the Bureau agrees to pay you, your
heirs or legal representatives, one cent for each pound of
smokeless powder dried by the method covered by your application or
applications filed or to be filed with the U.S. Patent Office,
provided a patent or patents is or are issued to you therefor."
"Respectfully,"
CHARLES O'NEIL
Chief of Bureau of Ordnance
"Mr. Louis Gathmann"
"1839 Vernon Avenue"
"Washington, D.C."
Page 260 U. S. 670
At the time of the conversation of Gathmann with the Chief of
Ordnance and his proposition and the reply to it, he, Gathmann,
contemplated applying for patents for his methods, and on February
9, 1903, and subsequent dates, made applications for patents, and
patents were issued to him for his methods, and at various times
from April, 1909, to April, 1915, the government made use of the
processes and methods covered by the patents in the manufacture of
smokeless powder to the amount of 23,675,061 pounds thereof, and
became indebted to the estate of Gathmann in the sum of the
petition, to-wit, $236,750.
A general traverse was filed to the claim. Upon the issues thus
formed and upon considering the evidence taken, the Court of Claims
made findings of fact, and from them deduced, as conclusion of law,
that appellant was not entitled to recovery, and dismissed her
petition.
The court decided that the proposition made by Gathmann's
communication and the reply thereto presented an option only, and
not a contract, and that it was terminated by the Bureau by a
letter addressed to Gathmann, October 14, 1904, which was as
follows:
"Referring to your apparatus for drying power, installed at the
naval proving ground for trial: the Bureau forwards herewith a copy
of the report made by the inspector of ordnance in charge of that
station for your information. After carefully considering this
report, the Bureau is of opinion that this apparatus has failed to
demonstrate anything that would warrant further experiment with it,
and the Bureau has instructed the inspector of ordnance in charge
of the naval proving ground that, when the drier can hold no more
samples, the whole amount be put in the dry house until dried to
the proper volatiles."
The court decided, besides, that the government had not used
Gathmann's methods. Appellant attacks both
Page 260 U. S. 671
rulings, but concentrates her attention upon the first. The
existence of the second, she assumes, is demonstrated by the
physical laws of nature, of which the court will take judicial
notice.
The specifications of error against the first ruling are as
follows:
"(1) The letters made an express contract of license for the
full term of the patents; (2) the license could not be renounced or
ended in any manner except by mutual consent or the fault of Mr.
Gathmann; (3) he had the right after the receipt of the letter of
October 14, 1904, to regard the license still in force, and to sue
for the unpaid royalties, the government having used the inventions
thereafter; (4) what was said prior to the letters of March 26 and
28, 1903, should not be considered; (5) the Court of Claims should
not have considered the development and state of the art prior to
the issuance of the patents; (6) the licensee is estopped from
denying the validity of the patents."
To estimate these contentions, the findings of the court must be
considered. A summary of them, stated narratively, is as
follows:
The material of smokeless powder, in its first stages, is in a
plastic condition, containing about 40% of moisture due to the
presence of ether and alcohol, called the "solvent." To make the
powder ready for use, the solvent must be reduced to between 4% and
7%, according to caliber. The process requires several months'
time. The elements of the solvent were expensive, and it became an
object to the government and its manufacture of the powder to save
them for reuse.
As early as 1900, the government had used, along with other
methods of drying, what was known as the closed-circuit method of
drying and solvent recovery. In this method, there is, generally
speaking, a heating chamber, a powder chamber, and a condensing
chamber, with the
Page 260 U. S. 672
necessary connecting pipes or conduits and means for effecting
circulation of the air in the circuit, as by fan or by gravity. In
operation, the warm air from the heating chamber passes on to the
powder chamber, where it absorbs solvent from the "green" powder,
then passes on to the condensing chamber, where the solvent carried
by it is condensed to liquid form, the air then passing on to the
heating chamber again for reheating and repetition of the
cycle.
When the powder is newly made, or "green," the solvent is given
off rapidly; but as the percentage of the solvent in the mass is
reduced, it volatilizes less rapidly and comes off less freely.
When the solvent is reduced to about 10%, this closed-circuit
process is discontinued and the drying of the powder is completed
in the ordinary drying houses.
The plans of the apparatus used by the government in 1900 were
secured from the California Powder Works, of California, by whom
the apparatus was understood to have originated. It illustrates
"the closed-circuit method."
Louis Gathmann was an inventor, and was interested in improving
the method of expediting the manufacture of smokeless powder, and
had discussed the question with Admiral O'Neil. The government at
times had two system -- one for merely drying by hot air and the
other for both drying and recovery of the solvent. Gathmann claimed
a method that would do both in a very much shorter time, and
proposed that a test be made. The letters we have quoted grew out
of the conferences between Gathmann and Admiral O'Neil, and
Gathmann's representation furnished the chief inducement to the
Admiral to enter into the agreement shown by the letters.
Pursuant to the agreement or option shown by the letters, the
United States, under the direction and supervision of Gathmann at
its own expense, constructed and
Page 260 U. S. 673
exhaustively tested at its Indian Head (Maryland) powder plant
the experimental apparatus and method so proposed by Gathmann. The
apparatus and method were substantially the same as those shown and
described in Gathmann's letters patent.
The tests began in October, 1903, and continued until October,
1904, during which time reports of the results obtained by the
tests, comparative and otherwise, were periodically made by the
officer making the tests, comparison being made with results
obtained from concurrent operations under the regular government
method. In making the tests, the instructions and wishes of
Gathmann were complied with except that he desired a continuous and
unbroken operation, though he had acceded at first to the closing
down of the operation of the government plant on Sundays. His
desire was not acceded to.
In the tests, the time required for drying the power was not
reduced, nor did it appear that the former methods used and results
obtained by the government in drying and solvent recovery were
otherwise improved upon, nor did Gathmann's apparatus work
satisfactorily to the Bureau of Ordnance, and, at the close of the
tests, Gathmann was so notified by a letter from the Acting Chief
of Ordnance.
No change was made in the government's solvent recovery and
drying processes as a result of the test of Gathmann's method.
On June 28, 1904, a patent, No. 763,387, in pursuance to his
application of February 9, 1903, was issued to Gathmann. On the
same day there was granted to Gathmann and his assignees of a
fourth interest therein, United States patent No. 763,388. These
patents and the applications upon which they were granted were the
applications and patents in contemplation by Gathmann and Admiral
O'Neil in their respective letters of March 24 and 26, 1903.
Page 260 U. S. 674
Beginning in 1907, the Navy Department, at various times in the
manufacture of smokeless powder, used drying and solvent recovery
apparatuses and methods.
They are illustrated by figures attached to the findings. From
August 1, 1910, to 1916, an apparatus known as the box-type method
was used, in which "the circulation is gravity circulation, induced
wholly by the heating and the cooling of the air in the different
parts of the circuit." It is not necessary to reproduce the
illustrations, and the processes need but little explanation. They
are all of the closed-circuit method of drying and solvent
recovery. All have a heating chamber, a powder chamber, and a
condensing chamber, with connecting pipes or conduits and means of
effecting circulation of air in the circuit, as by fan or by
gravity. It is not necessary to compare their mechanisms. We think
that the apparatus received by the Bureau from the California
Powder Works did not differ in essential structure from them and,
of course, it differed from that of Gathmann's apparatus. And
differed from them necessarily, otherwise Gathmann would have had
no purpose in submitting a proposition to the Bureau. The
difference was in the method -- amount of vapor, means "provided,"
to quote the patent, "to produce a vapor-laden atmosphere in the
drying chamber" and "so as to maintain," and to quote the patent
further, "a substantially vapor-saturated atmosphere in the drying
chamber nearly to the end of the operation of drying. . . ." In
other words, the vapor from the moisture of the materials was added
to "by admitting vapor as steam."
Considering the methods, their illustrations, and the letters
exchanged by Gathmann to the Bureau of Ordnance, the conclusion of
the Court of Claims was that a contract was not created. "At most,"
the conclusion was,
"a mere option was granted by Gathmann to the government to use
his method if found suitable after making
Page 260 U. S. 675
a test of certain apparatus furnished by him, which he continued
to improve or change."
And again:
"There was never any agreement between the parties to use
Gathmann's method, and all we have is, as has been stated, an
option granted, declined and terminated."
This conclusion appellant resists, and insists here, as she
insisted in the Court of Claims, that a contract was created with
its comprehensive and determining effect, it having continued, is
the contention, after the date of the letters. That a contract
existed or continued we cannot concede to appellant. But whether
option or contract, we think it was terminated. There was an
election given to the government to be exercised by it according to
the judgment of its officers of a test of the "experimental
apparatus" submitted by Gathmann. The test was made, judgment was
exercised, and its effect notified to Gathmann in the letter of
October 14, 1904. Gathmann's letter gave "the option of using" his
"method of drying materials if they [Navy Department] find it to
their advantage, by paying to" him, his heirs or legal
representatives "$0.01 (one cent) for each pound of material dried
by" his "method."
Clearly, therefore, there was a conditional proposal, and an
acceptance upon the condition that the apparatus, after test,
should work "satisfactorily to the Bureau." It did not so work, and
the Bureau so declared to Gathmann.
It is true that there was no response by Gathmann to the letter
of the Bureau. His silence, however, was tantamount to
acquiescence. It does not appear when that silence was broken. The
original petition was filed in this case April 17, 1915 -- that is,
more than ten years after the Bureau's action in declining the
proposal. We think that he could not keep the government in
obligation, uncertainty, and restraint all that time, or even until
April, 1909, the first date alleged of the use by the
Page 260 U. S. 676
government of his apparatus. He therefore must be considered as
having accepted the decision of the Bureau and the termination of
the relation created by the letters, whether it was obligation or
option, "right" or "privilege." Responding, therefore, to the
contention of appellant that a contract (license, to use
appellant's word) can "not be renounced or ended in any manner
except by mutual consent or the fault of Gathmann," we think there
was such consent -- that which must be considered as tantamount to
consent.
We do not think it is necessary to review the claims of the
patents and wherein either of them is an advance upon the uses and
knowledge of the world, and, necessarily, including the methods of
the government. The Court of Claims has done this, and, we think,
so satisfactorily that we content ourselves by referring to its
opinion. We need only to say that Gathmann emphasized the
distinction of his patents from all that preceded them as using a
"vaporous or vapor-laden atmosphere," and that such necessarily
existed or will occur in the methods used by the government.
It is counsel's contention that it is
"inevitable that vaporous and vapor-laden atmosphere would be
created the instant the heated air came in contact with the green
powder, and would continue vaporous and vapor-laden until all of
the alcohol and ether were extracted from the powder or the powder
be removed from the drier."
And of this, it is asserted, this Court takes judicial notice as
"the law of physics," and the further assertion is that:
"Of course, this contact of the heated air with the alcohol and
ether caused the air to become vapor-laden, whether the defendant
wished it or not. "
The assertions prove too much. They leave the patents without
basis, and the distinction they express and dwell on as merely
verbal. If the asserted result was inevitable in the method of the
patents, it was inevitable in the method
Page 260 U. S. 677
in use prior to the patents, and, we repeat, the patents are
left without justification.
The conclusion therefore must be that, if the methods of the
patents are different from the prior art by reason of the "initial
vapor-laden atmosphere by admitting vapor as steam," the government
does not use it; if that be not its distinction, and the methods of
the prior art inevitably have it, the patents are no advance upon
that art, and are invalid.
Judgment affirmed.
