4. But when obtained, no person except the patentee, has any right to make, sell, or use the article patented, until the time has expired for which this exclusive right was granted, without the permission of the patentee. Any person doing so is liable to a heavy penalty, and may be prosecuted in the Circuit Court of the United States; this court having original jurisdiction in all cases arising under the patent laws. But a writ of error or an appeal lies to the Supreme Court of the United States. 5. The Patent Office, when first established, was a bureau of the State Department, and the Commissioner of Patents acted under the direction of the Secretary of State. But after the creation of the Department of the Interior, in 1849, it was transferred to it, became a bureau of the new department, and the commissioner now acts under the general direction of its secretary. THE COMMISSIONER OF PATENTS 6. Is appointed by the President and Senate. His duties are best explained in the language of the law itself, which, in speaking of the creation and appointment of this official, says that his duties shall be “to superintend, execute and perform all such acts and things touching and respecting the granting and issuing of patents for new and useful discoveries, inventions and improvements, as are herein provided for, or shall hereafter be by law directed to be done and performed.” He has the charge and custody of all books, records, papers, models, machines, and all other things belonging to the patent office; and has the privilege of sending and receiving letters and packages by mail, relating to the business of the office, free of postage. He has the power to appoint his clerks, examiners and subordinates; among whom are patent office agents, who may be appointed in not more than twenty of the principal cities and towns in the United States. It is their duty to forward to the patent office all such models, specimens and manufactures, as shall be intended to be patented. 7. In cases of appeal from the decision of the commissioner, the appeal may be made to the board of examiners, or to the Chief Justice of the District Court of the United States for the District of Columbia. There is a seal for the patent office, which the commissioner keeps, and which he must affix to patents when granted, and to other papers and records issued from his office, which are wanted as evidence in other places. He is also authorized to publish a classified and alphabetical list of all patents issued at the patent office. This he frequently does, for the information of the public. CHAPTER XXXV. PENSIONS.
