in dealing in any commodity, and for this right a royal fee was exacted.
>From this fact the term _royalty_ originated.

An international agreement is now in force among nearly all countries,
which respects the filing of an application in any country, for a period
of one year in the other countries.

In making an application for a patent, a petition is required, a
specification showing its object, use, and particular construction,
followed by a claim, or claims, and accompanied by a drawing, if the
invention will permit of it, (which must be made in black, with India
ink), and an oath.

The oath requires the following assertions: That the applicant is the
first and original inventor of the device, and that he does not know
and does not believe the same was ever known or used before his
invention or more than two years before his application.

He must also further allege that the invention was not patented or
described in any printed publication here or abroad, and not
manufactured more than two years prior to the application, and that he
has not made an application, nor authorized any one to do so more than
two years prior to his application.

The first Government fee is $15, payable at the time of filing, and the
second and final fee is $20, payable at the time the patent is ordered
to issue.

The filing of an application for patent is a secret act, and the Patent
Office will not give any information to others concerning it, prior to
the issue of the patent.
