To Whom Letters Patent Are Granted

Section 4886 of the Revised

Statutes of the United States provides that: "Any person who has

invented or discovered any new and useful art, machine, manufacture or

composition of matter, or any new and useful improvement thereof, not

known or used by others in this country, and not patented or described

in any printed publication in this or any foreign country, before his

invention or discovery thereof, and not in publ c use, or on sale for

more than two years prior to his application, unless the same is proved

to have been abandoned, may, upon the payment of the fees required by

law, and other due proceedings had, obtain a patent therefor."



And section 4888 of the same Statute enacts:



Section 4888. Before any inventor or discoverer shall receive a patent

for his invention or discovery, he shall make application therefor, in

writing, to the Commissioner of Patents, and shall file in the Patent

Office a written description of the same, and of the manner and process

of making, constructing, compounding, and using it, in such full,

clear, concise and exact terms, as to enable any person skilled in the

art or science to which it appertains, or with which it is most nearly

connected, to make, construct, compound, and use the same; and in case

of a machine, he shall explain the principle thereof and the best mode

in which he has contemplated applying that principle, so as to

distinguish it from other inventions; and he shall particularly point

out and distinctly claim that part, improvement or combination which he

claims as his invention or discovery. The specification and claim shall

be signed by the inventor and attested by two witnesses.



It is also required by law that when "The case admits of drawings," it

shall be properly illustrated; and also, if the Commissioner requires

it, that a model shall be furnished in cases capable of such

demonstration.



The cost of obtaining Letters Patent in ordinary cases is: First,

Government fees, $15; counsel fees, including drawings, $25; second, or

final Government fees, to be paid within six months from date of

allowance, $20; total, $60.
