1. A contract concerning the use of a patented invention bound
the "parties and their legal representatives to the covenants and
agreements of the contract." A plea alleged that the defendants
"are the legal representatives and successors and assignees in
business and interest" of one of the parties. The question being on
the sufficiency of this plea,
held that the defendants
were the legal representatives of that party within the meaning of
the contract.
2. An allegation that L. refused to manufacture and furnish his
invention as he had agreed to do is equivalent to an allegation of
a demand on him to do so and a refusal.
3. Where an inventor signed several different agreements with
the same party on the same day for the sale of his invention and
for a license to us it, they must all be construed together, and if
it is apparent that he intended to convey the right to use a new
invention in connection with former patents under any renewal or
extension of the former, the grantee or assignee is protected,
though the improvement was never patented and though the
Page 92 U. S. 725
reissued patent was extended afterwards. It is a question of
intention to be gathered from all the instruments of writing in the
case.
4. The rights growing out of an invention may be sold, including
the right to use it, though no patent ever issues for it.
MR. JUSTICE MILLER delivered the opinion of the Court.
On the eighteenth day of November, 1856, a patent issued to
Lafayette Louis for an invention which produced a tremolo in the
musical notes of melodeons or reed instruments, and which has since
become known as the tremolo attachment. Louis surrendered and
obtained reissues of this patent on the twenty-sixth day of
February, 1867, and again on the twenty-sixth day of May, 1868, and
after his death, his wife, who was his administratrix, obtained in
July, 1871, what appears to have been both a reissue and a renewal
for seven years of the same patent, the whole right in which she
assigned to plaintiffs May 30, 1872.
Whereupon the present suit, which is a bill in chancery, is
brought against the defendants, as infringers, for an injunction
and for an account of profits and other relief.
The defendants, not denying the allegation of the use of the
invention, interpose a plea, and on this plea the case was heard
and a decree rendered dismissing the bill.
The plea sets up the right to use the invention described in the
reissued patent of 1872, in defendants, as shown by five several
written instruments, signed by Louis in his lifetime, which were
made parts of the plea as exhibits A, B, C, D, and E.
The first of these is a contract between said Louis and Henry
Mason and Emmons Hamlin, for the use by the latter in their
melodeons, of the original invention of Louis, and is dated April
10, 1861. Exhibit B is a copy of an application by Louis for a
patent for an improvement in his tremolo attachment, with the
accompanying specifications, and is dated Sept. 25, 1868. Exhibits
C, D, and E are all dated the same day as this application,
Page 92 U. S. 726
and are contracts between said Louis and the Mason and Hamlin
Organ Company for the sale of this improvement and its use in
connection with the invention already patented in 1856 and reissued
in 1867 and 1868.
Exhibit A is a contract by which Louis agrees to furnish to
Mason and Hamlin his patent tremolo attachment in such numbers and
as they may order them, at one dollar for each attachment, and if
he fails to furnish them as ordered, Mason and Hamlin are licensed
to make, use, and sell the same in connection with all musical
instruments manufactured by them anywhere in the United States. The
closing paragraph of this contract declares that
"The said parties mutually bind themselves and their legal
representatives to the covenants and agreements herein contained,
to continue in force until the full expiration of the term for
which said letters patent have been granted, and during such period
as the same may be hereafter renewed or extended."
It is not alleged that any of the subsequent contracts abrogated
this one. It cannot be denied that this contract extends to the
renewal of the patent which was assigned to plaintiffs. The only
question on this branch of the plea is whether the Mason and Hamlin
Organ Company are entitled to the rights of Mason and Hamlin.
As the case was decided on the sufficiency of the plea, its
allegations must be taken as true, and all that can be reasonably
inferred from those allegations and from the various exhibits which
it makes must also be held to be true. The plea does allege that
the defendants are "the legal representatives and successors and
assignees in business and interest of said Mason and Hamlin." This
allegation seems to be full and specific, and the only doubt of its
sufficiency arises as to whether the legal representatives spoken
of in the agreement are or can be others than executors,
administrators, or heirs. Whatever doubt might be entertained on
this point we think is solved by the fact that Louis, in the
subsequent contracts of 1868, seems throughout to treat with the
corporation as successors of Mason and Hamlin in the contract of
1861. For in exhibit E he sells and assigns to the company the
exclusive right to use his supposed improvement under the patent
of
Page 92 U. S. 727
1856 and all the subsequent reissues, and as this new
improvement required the use of the old, he seems here to recognize
the right of the company to control the license he had previously
granted to Mason and Hamlin.
We are of opinion, therefore, that the defendant corporation is
entitled to the benefit of the contract between Mason and Hamlin
covered by exhibit A, and that this gives them the right to use the
attachment under the extension of the original patent now assigned
to plaintiffs.
It is said that defendants never demanded these attachments, and
therefore they had no right to make them.
But the allegation is full that Louis at all times refused to
manufacture and furnish the attachment to defendants, and we think
under the contract, this authorized them to make them for
themselves.
The court below, however, rested its decision on another ground
which we think equally conclusive.
As we have already said, Louis signed these contracts with the
defendant company on the same day that he made his application for
a patent for his improvement in the tremolo. The supposed
improvement consisted in a different construction of the parts
already patented by him. By the first contract (exhibit C), he
sold to the defendant this invention wholly, and
authorized the patent to issue to the company. By the second
(exhibit D), he licensed them to use this new invention or
improvement in connection with his former patents and in connection
with a patent of his of 1862 for an improvement in pianos with
melodeon attachments, and the company agreed to pay him a royalty
of one dollar each for his new tremolo attachment, at an average of
forty attachments per month. The third contract (exhibit E)
provides that if the company fail in securing a patent for the
improvement sold to them, referring to his original patent and
reissues, and to his sale of the later invention, and his claim to
use it in connection with the old patents, he grants to the
defendants the exclusive right, under the letters patent already
granted, and under
any and all reissues thereof, to make,
use, and sell the specific mechanism described and set forth in the
application for the new patent.
Without elaborating this matter, we concur in the opinion
Page 92 U. S. 728
of the circuit court, that Louis, having sold this invention,
and doubt existing whether the purchasers would obtain a patent for
it, intended by this contract and by exhibit D to secure to them
the benefit of the exclusive use of that invention, in connection
with his first mechanism, so long as the latter was protected by
any patent founded on his right an inventor. It was this use for
which defendants are sued in this case.
While it is perhaps not necessary to decide whether in any case
a sale of an invention which is never patented carries with it
anything of value, we are of opinion that the rights growing out of
an invention may be sold, and that in the present case the sale,
with the right to use it in connection with the existing patent and
its reissues or renewals, protects defendants from liability as
infringers.
Decree affirmed.
