EXTENSION OF PATENTS
[cIRcULAR.l


TN1E undersigned, constituted by law 4Ai
i decide upon applications for the F% AssE
patents, have adopted the following s. N3R3fss
rules, for the benefit of those person
hereafter apply for extensions.
The questions which arise on each app
extension
/. Is the invention novel;
2. Is it useful?
3. Is it valuable and important to the publit
4. Has the inventor been adequately remti,
for his time and expense in originating and pc
ing it,
5 Has he used due diligence in introducing
invention into general user
The two first questions viii lie determined upoA
the result of an examination IN the Patent Office;
as will also the third, to some extent.
To enable the boar1 z, come 10 a correct conclu-
sion in regard to the thd p,nt of inquiry, the APP
plicant should, If posshl. procure the testimony Of
persons DISTINGUISHED in the invention which testi-
mony should be taken Under oath.
In regard to the fourth and fifth points ofinquiry,
in addition to his oath showing his receipts and
expenditures on account Of the invention, by which
its value is to be ascertained, the applicant should
show, by the testimony of disinterested witnesses
on oath that he has taken all reasonable measures
to introduce his invention into general use and that,
without default neglect on 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 lie 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, If
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
time and place taking said testimony, which shall
be taken according to the rules prescribed by the
of Patents of pnce
All arguments submitted to the board must be in
writing.
In conclusion, the undersigned would remark,
generally that monopoly of his invention il 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
perfecting it. At the end of Tie time for which his
patent runs, his monopoly should cease, and the in
vention become public property unless he can show
good reasons to the contrary. The presumption is
always against his application; and if he cannot
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 perecting it,
the board cannot grant an extension.
