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 public 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."

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.

shall be properly illustrated; and also, if the Commissioner requires
it, that a model shall be furnished in cases capable of such
