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.

One of the essential requirements of the Boy Scout training is a KNOWLEDGE OF WOODCRAFT. This necessitates a book embracing all the subjects and treating on all the topics that a thorough knowledge of WOODCRAFT implies.

This book thoroughly exhausts the subject. It imparts a comprehensive knowledge of woods from fungus growth to the most stately monarch of the 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!
