In every original application the applicant must distinctly state under oath that the invention has not been patented or described in any printed pub- lication in any country before his inven- tion or discovery thereof or more than two years prior to his application. If any application for patent has been filed in any foreign country by the applicant in the United States, or by his legal rep- resentatives or assigns, prior to his application in the United States, he shall state the country or countries in which such application has been filed, giving the date of such application, and shall also state that no application has been filed in any other country or countries than those mentioned; that to the best of his knowledge and belief the invention had not been in public use or on sale in the United States, for more than two years prior to his application.

Reissue applica- tions must be made and the specifications sworn to by the inventors if they be living.
