PATENT OFFICE, January 1, 1 838.
SIR : In obedience to the law for promoting the progress of science and
useful arts, the Conimissioner of Patents would respectfully report:
That, during the year 1837, four hundred and thirty-five patents have
been issued from the Patent. Office, of which classified and alphabetical
lists are annexed, marked A and B.
That, during the same period, one hundred and sixty-eight patents
have expired and become public property, as by list annexed, marked C.
That the receipts for patents, caveats, disclaimers, improvements, and
copies for the year, amount to twenty-nine thousand two hundred and
eighty-nine dollars and eight cents, from which may be deducted three
thousand three hundred and twenty dollars, paid on applications' with-
,drawn, as by statement annexed, marked D.
That the payments made for the restoration of models, records, and
drawings, consumed by the late fire, amount to ten thousand seven hun-
dred and five dollars and fifteen cents, as exhibited in the statement
marked E.
That the ordinary expenditures of the office have been nineteen thou-
sand four hundred and eighty-one dollars and eighty-three cents, as by
account marked F. These expenses have been increased for the year
1837, by the purchase of furniture, record-books, &c., destroyed in the fire
of December, 1836.
The utmost economy has been used in replacing these articles, and no
more have been procured than were indispensably necessary. The furni-
ture has been selected with reference to the new building, when the same
shall be completed and fit for use.
The number of patents issued during the year 1837 is less than in some
preceding years. This is to be attributed chiefly to the operation of the
new law, which subjects all applications for patents to a careful examina-
tion as to the originality of the invention claimed. Power is given to the
Commissioner to refuse a patent if the invention is not deemed sufficiently
useful; but this power is seldom exercised, and is confined to cases wheie
