[oIRouLAR.l

PATENT oFrIcE, June 81, 1916
| 1NHE undersigned, constituted by law a board t
! Il decide upon applications for the extension o.
patents have adopted the following suggestions ant
rules, for the benefit of those persons who may
| hereafter apply for extensions.
The question: which arise on each application fol
an extension ar
| l. Is the invenlion nopei?
g Is 1t usefuR
| g. Is it paiuabie and important to the publici
| a. Has the inventor been adequately remuneratcd
for his time and expense in originating and perfect.
| ing IT.
5 Has he used due diligence in introducing his
| invention into general use'
| 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
pllcant should if possible procure the testimony OF
persons dsinteresled in the invention which testi-
| mony should be taken under oath.
In regard To the fourth and fifth points ofinquiry
IN addition to his own oath showing his receipts and
expenditures account of the invention, by which
its value is to be ascertaned, 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 a
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 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 of taking said testimony, which shall
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
perfecting 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
good reasons to the contrary. The presumption is
always against his applications and if he cannot
show that 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.
