PATENT OrrIcE, June 81, ls45.
TIME undersigned, constituted by law board tc
Il decide upon applications for the extension o.
patents, have adopted the following suggestions and
rules, for the benefit Of those persons who may
hereafter apply for extensions.
The questions which arise on each application fol
an extension are
i. Is the invention novel?
2. Is 1t useful?
3. Is it paiiabie and important to the publici
4. Has the inventor been adequately remunerated
for his time and expense in originating and perfect
ing it,
5. Has he used due diligence in introducing his
invention into general use9
The two first questions will be determined upon
the result of an examination in the Patent Office
as will also the third, to some extent.
To enable the board TO come to correct conclu-
sion in regard to the third point of INQUIRY, the APP
plcan should, if possible, procure the testimony Of
persons disneresed in the invention, which testi-
mony should be taken under oath.
In regard to the fourth and fifth points of inquiry
in addition TO his own oath showing his receipts and
expenditures on accounrof the invention, by which
its value is to be ascertaincd the applicant should
show, by the testimony of disneresed witnesses
on oath, that he has taken all reasonable measures
to introduce his invention into general use, and that
without default neglect his part, he has failed
to obtain from the use and sale of the invention
reasonable remuneration for the time, ingenuity
and expense bestowed on the same, and the intro
duction thereof into use.
The report of the examiner upon the novelty and
utility of the invention, will be ready fifteen days
before the day appointed for the hearing, which will
be open for inspection at the Patent Office; copies OF
which will be furnished to all parties interested, il
desired, on payment of the usual fees for copies.
In case of opposition by any person to the extern
sion of patent, both parties may take testimony
each giving reasonable notice to the other of the
and t,lace nff taking sail tes which hall
be taken according to the rules prescribed by the
Commissioner of Patents in cases of interference
All arguments submitted to the board must be in
writing.
In conclusion, the undersigned would remark
generally, that monopoly of his invention is Sc
cured by law to the inventor for the term Of four
teen years. This is done with view to compen-
safe him for his time and expense in originating and
perfectng it. At the end of the time for which his
patent runs his monopoly should cease, and the in
vention become public property unless he can show
show tina; his invention is novel, useful, valuable,
and important to the public, and that having made
all reasonable effort to introduce it into general use,
he has not been adequately remunerated for his
time and expenses in discovering and perfecting it,
the board cannot grant an extension.
