INVENTIONS AND PATENTS, AND INFORMATION ABOUT THE RIGHTS AND DUTIES OF
INVENTORS AND WORKMEN
There is no trade or occupation which calls forth the inventive faculty
to a greater degree than the machinist's. Whether it be in the direction
of making some new tool, needed in some special work, or in devising a
particular movement, or mechanical expedient, the machinist must be
prepared to meet the issues and decide on the best structural
arrangement.
Opportunities also come daily to the workers in machine shops to a
greater extent than other artisans, because inventors in every line
bring inventions to them to be built and experimentally tested.
A knowledge of the rights and duties of inventors, and of the men who
build the models, is very desirable; and for your convenience we append
the following information:
The inventor of a device is he who has conceived an idea and has put it
into some concrete form.
A mere idea is not an invention.
The article so conceived and constructed, must be both _new_ and
_useful_. There must be some utility. It may be simply a toy, or
something to amuse.
If A has an idea, and he employs and pays B to work out the device, and
put it into practical shape, A is the inventor, although B may have
materially modified, or even wholly changed it. B is simply the agent or
tool to bring it to perfection, and his pay for doing the work is his
compensation.
An inventor has two years' time within which he may apply for a patent,
after he has completed his device and begun the sale of it. If he sells
the article for more than two years before applying for a patent, this
will bar a grant.
Two or more inventors may apply for a patent, provided each has
contributed something toward bringing it to its perfected state. Each
cannot apply separately. The patent issued will be owned by them
jointly.
Joint owners of a patent are not partners, unless they have signed
partnership papers respecting the patent. Because they are partners in
some other enterprise, disconnected from the patent, that does not
constitute them partners in the patent. They are merely joint owners.
If they have no special agreement with respect to the patent each can
grant licenses to manufacture, independently of the others, without
being compelled to account to the others, and each has a right to sell
his interest without asking permission of the others.
An _inventor_ is one who has devised an invention. A _patentee_ is one
who owns a patent, or an interest in one, be he the inventor or not.
The United States government does not grant Caveats. The only protection
offered is by way of patent.
A patent runs for a period of seventeen years, and may be renewed by act
of Congress only, for a further term of seven years.
An interference is a proceeding in the Patent Office to determine who is
the first inventor of a device. The following is a brief statement of
the course followed:
When two or more applicants have applications pending, which, in the
opinion of the Examiner, appear to be similar, the Office may declare an
interference.
If an applicant has an application pending, and the Examiner rejects it
on reference to a patent already issued, the applicant may demand an
interference, and the Office will then grant a hearing to determine
which of the two is entitled to the patent.
The first step, after the declaration of interference, is to request
that each applicant file a preliminary statement, under oath, in which
he must set forth the following:
First: The date of conception of the invention.
Second: Date of the first reduction to writing, or the preparation of
drawings.
Third: Date of making of the first model or device.
Fourth: When a complete machine was first produced.
These statements are filed in the Patent Office, and opened on the same
day, and times are then set for the respective parties to take
testimony.
If one of the parties was the first to conceive and reduce to practice,
as well as the first to file his application, he will be adjudged to be
the first inventor, without necessitating the taking of testimony.
If, on the other hand, one was the first to conceive, and the other the
first to file, then testimony will be required to determine the question
of invention.
The granting of a patent is not conclusive that the patentee was, in
reality, the first inventor. The law is that the patent must issue to
the _first_ inventor, and if it can be proven that another party was the
first, a new patent will issue to the one who thus establishes his
right. The Commissioner of Patents has no right to take away the patent
first issued. Only the Courts are competent to do this.
A patent is granted for the right to _make_, to _use_ and to _vend_.
An owner of a patent cannot sell the right only to make, or to sell, or
to use. Such a document would be a simple license, only, for that
particular purpose.
A patent may be sold giving a divided, or an undivided right.
A divided right is where a State, or any other particular territorial
right is granted. An undivided right is a quarter, or a half, or some
other portion in the patent itself.
If an inventor assigns his invention, and states in the granting clause
that he conveys "all his right and title in and to the invention," or
words to that effect, he conveys all his rights throughout the world.
If the conveyance says, "all rights and title in and throughout the
United States," he thereby reserves all other countries.
If a patent is issued, and the number and date of the patent are given,
the assignment conveys the patent for the United States only, unless
foreign countries are specifically mentioned.
To convey an invention or patent, some definite number or filing date
must be given in the document, with sufficient clearness and certainty
to show the intent of the assignor.
An invention does not depend on quantity, but on quality. It is that
which produces a new and a useful _result_.
In the United States patents are granted for the purpose of promoting
the useful arts and sciences.
In England, and in many other foreign countries, patents are granted,
not on account of any merit on the part of the inventor, but as a favor
of the crown, or sovereign.
Originally patents were granted by the crown for the exclusive privilege
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.

WOODCRAFT _for_ Boy Scouts and Others
_By_ OWEN JONES _and_ MARCUS WOODMAN _With a Message to Boy Scouts by_
SIR BADEN-POWELL, _Founder of the Boy Scouts' Movement_.

KNOWLEDGE OF WOODCRAFT. This necessitates a book embracing all the
subjects and treating on all the topics that a thorough knowledge of
WOODCRAFT implies.

forest; it treats of the habits and lairs of all the feathered and furry
inhabitants of the woods. Shows how to trail wild animals; how to
identify birds and beasts by their tracks, calls, etc. Tells how to
forecast the weather, and in fact; treats on every phase of nature with
which a Boy Scout or any woodman or lover of nature should be familiar.
The authorship guarantees it's authenticity and reliability.
Indispensable to "Boy Scouts" and others. Printed from large clear type
on superior paper.
Embellished With Over 100 Thumb Nail Illustrations Taken From Life
Bound in Cloth. Stamped with unique and appropriate designs in ink!
