The Patent-Office is a bureau of the Interior Department, wherein are kept and preserved all the records, books, models, drawings, specifications and other papers and things pertaining to patents for inventions.

In the Patent-Office are the following officers, appointed by the President: A Commissioner of Patents, an Assistant Commissioner of patents, and three Examiners-in-chief.

All the other officers, clerks and employes, named below, are appointed by the Secretary of the Interior, on the nomination of the Commissioner of Patents, their salaries varying from $900 to $2,500 per year: A chief clerk, an examiner in charge of interferences, one examiner in charge of trade-marks, twenty-four principal examiners, twenty-four first assistant examiners, twenty-four second assistant examiners (two of whom may be females), twenty-four third assistant examiners, a librarian, one machinist, three skilled draughtsmen, thirty-five copyists of drawings, one messenger and purchasing clerk, one skilled laborer, eight attendants in the model room, and eight others in the same room.

The Patent-Office has a seal, with which letters-patent and papers issued from it are authenticated.

The Commissioner of Patents and the chief clerk are severally required to give a bond for the faithful discharge of their duties, and a true accounting of public moneys coming into their hands.

Must Not Be Pecuniarily Interested

No officer or employe of the Patent-Office is allowed to acquire or take, during his or her term of service, any right or interest, directly or indirectly, except by inheritance or bequest, in any patent issued by the office.

Under the direction of the Secretary of the Interior, the Commissioner of Patents superintends or performs all duties respecting the granting and issuing of patents directed by the laws, and has charge of all books, records, papers, models, machines and other things belonging to the Patent-Office.

He, subject to the approval of the Secretary of the Interior, from time to time, establishes regulations, consistent with law, for the conduct of proceedings in his office. He also causes to be classified and arranged in suitable cases, in rooms and galleries of the Patent-Office, set apart for that purpose, the models, specimens of composition, fabrics, manufactures, works of art and designs which are deposited in the Patent-Office; and these rooms and galleries are kept open during suitable hours for inspection by visitors.

He may restore to the respective applicants such models accompanying rejected applications for patents as he deems it unnecessary to preserve, or he may sell or otherwise dispose of them after the application has been finally rejected for a year, paying the purchase-money into the Treasury, as other patent-moneys are directed to be paid.

Description Of Patents

He may cause to be printed copies of the patent-claims of current issue, and copies of such laws, decisions, regulations and circulars as may be necessary for the information of the public.

He is authorized to have printed, from time to time, for free distribution a limited number of the complete specifications and drawings of each patent, together with suitable indexes, one copy being placed for free public inspection in each State-house of every State and Territory, copies for the like purpose in the clerks' offices of the Federal district courts, and one in the library of Congress - all being certified under the hand of the Commissioner and seal of the Patent-Office, and not to be taken from their places of deposit for any other purpose than as evidence in suits at law.

He is also authorized to have printed such additional copies of these specifications and drawings, duly certified, for sale at a price as low as may be warranted by the actual cost and demand for them, and to furnish a complete set of them to any public library that will pay for binding and transporting them and will provide suitable places of deposit, open to the public.

The lithographing and engraving are done by contract after competitive bidding, and the printing is done at the Government Printing-office.
