No special form is prescribed for licenses, and their terms will vary according to the special contract between the parties. The following forms, however, may be useful as guides: License-Shop right.

For the sake of uniformity and convenience, the remaining fees are required to be paid in the same manner; that is to say, before the labor is performed for which they are to be received in payment.

The final fee on issuing a patent must be paid within six months after the time at which the patent was allowed, and notice thereof sent to the applicant or his agent. And if the final fee for such patent be not paid within that time, the patent will be withheld, and the invention therein described become public property as against the applicant therefor, unless he shall file a new application therefor within two years from the date of the allowance of the original application. The money for the payment of fees may be paid to the Commissioner or deposited with an Assistant Treasurer of the United States, or other officer authorized to receive the same, taking his certificate, and remitting the same to the Office, directed to the Commissioner of Patents.

Letters containing money should be regis tered at the post-office where mailed. In no case should money be enclosed with models. TAKING AND TRANSMITTING TESTIMONY. In interferences and other contested cases, the testimony of witnesses is taken on oath by written depositions in the presence of a magistrate, by whom the questions and answers are written down and afterwards transmitted under seal to the Commissioner of Patents. Due notice must be given by the party examining the witness to the other party, in order that he may be present personally or by attorney, and cross-examine. The rules established by the Office, in reference to the taking and transmitting of evidence in such cases, will be furnished gratis on application to the Commissioner. THE DOMINION OF CANADA.
