Where the United States, without disclosure to it of the scope
of an application for patent, obtained by a contract with the
applicant a license at certain rates, to manufacture and use the
devices covered by the application, and was later sued by the
licensor for its use of a device procured from another, which the
licensor claimed came within his application and subsequent patent,
held: (a) that the government was not estopped from
showing, by attendant facts and circumstances, that the contract
was not intended by the parties to apply to the device so used, and
(b) that a judgment of the Court of Claims, so limiting the
contract, upon facts found, was not erroneous as a matter of law.

MR. JUSTICE HOLMES delivered the opinion of the Court.
This is a suit upon a contract made between the claimant and the
United States on April 2, 1912. The contract
Page 263 U. S. 627
headed "Shop License," recites that the claimant is "owner of
the invention known as Steam Generator for Automobile Torpedoes
covered by applications" of which it is necessary to mention only
one, dated March 29, 1909; licenses the United States to
manufacture and use torpedoes equipped with Steam Generators
covered by the application to the end of the term for which patent
may be granted, and binds the United States to pay at certain rates
for such torpedoes. The claimant alleged that the United States had
used the devices covered by claims 1, 5 and 13 of letters patent
issued upon the above application on August 20, 1912. The Court of
Claims found that those devices had not been used by the United
States, but that the mechanism actually used by it was practically
identical with that of a rival, the E. W. Bliss Company, that had
been successfully tested in the fall of 1911, before the date of
the above contract and before the plaintiff had attempted but
failed to satisfy the same tests.
When this contract was made, the United States had not seen the
applications, which were the claimant's secret. Both parties knew
that the government was dealing also with a rival concern, and the
United States, at least, and probably the claimant, knew that the
rival had satisfied the government's tests, which the claimant had
not then done. It could not be believed that the contract meant a
blind acceptance of liability for whatever might be in an
undisclosed document. It did not; what it aimed at was a specific
device which it was given to understand had been invented. We do
not argue this at length, because the proposition is accepted by
the claimant --
"the purpose of the license agreement was to secure to appellee
the right to use the steam generator devised by Davison regardless
of any question as to the validity of patents he might obtain or as
to the scope of their claims."
The dealings began with proposals for applying a system to
existing torpedoes that would double their range, illustrated by
a
Page 263 U. S. 628
drawing showing the general arrangement of the device,
identifying it but not disclosing it in detail. They ended in the
contract, which went further, but undoubtedly had reference to a
system the general nature of which was understood.
We must take it on this record that, at the time, certain
elements in the construction of self-moving torpedoes were well
known. The front end contained the explosive. Behind that was a
chamber of compressed air that was transmitted to an engine moving
the propeller through a pipe with a valve that reduced the pressure
of the condensed air to the desired point and kept it constant. The
moving force was enhanced by heating the air after it left the
valve. This was done by passing it through a combustion chamber
into which was forced alcohol or other fuel. The fuel was in a
third chamber, and was carried to the place of combustion by the
condensed air through a second pipe from beyond the reducing valve.
It was ignited when the shell was launched. More was needed to
carry the torpedo the distance required to make it usable in modern
warfare. It was understood that the result could be accomplished
and danger to the contrivance from excessive heat avoided by the
introduction of water into the combustion chamber, where it would
become steam. The Bliss Company had given this knowledge a
practical form, and there is no warrant in the record as it comes
to us for suggesting that the claimant had anything to do with the
Bliss Company's success, or that the government had any reason for
thinking that it had. In deciding what the government reasonably
supposed that it was buying, these facts are important, and what
may have been contained in the undisclosed application is of little
or no weight. Whatever may have been the rights of the claimant as
against the Bliss Company, the government was entitled to assume
that they did not extend to the above elements, separately or
combined.
Page 263 U. S. 629
Manifestly, on these facts, the government is not estopped to
show that its contract applied only within narrow limits. If the
facts were as it has a right to suppose them to be, the contract
necessarily was so limited. The government thought that it might be
that the claimant had found a more perfect way to do what was
wanted and what the Bliss Company already had done, but, on the
record before us, it would be monstrous to suppose that it was
undertaking to pay the claimant for the Bliss Company product. The
claimant was thought by the government to have failed in its
undertaking, and therefore its device was laid aside. That device
had certain peculiarities not repeated by the Bliss Company's, but
the claimant relies and has to reply here upon the broad contention
that the introduction of water to the combustion chamber in an
effective way belongs to it, which seems unlikely in view of the
previous British patent to Sodeau, in 1907, and others, and which
it seems to us clearly might have been found, as by implication it
was found, by the Court of Claims not to have been the assumption
or the meaning of the contract. So far as appears, the use of water
by the Bliss Company owed nothing to Davison, the claimant's
assignor, but very closely embodied the suggestions of Sodeau and
other predecessors in the field. We cannot say as matter of law
that the Court of Claims was wrong.
Decree affirmed.
