Messrs. Editors—I took out two patenti through the Scientific American Agency, bearing date April 21st and Jul^ 21st of last year and I now wish to return you my sincere thanks and good-will for the reliable an( beneficial information I received from yoi and your Examiners. You gave me m trouble in securing my rights; and I nov discover that you have made my claims t( cover both inventions much broader than ] expected, which has made my claims of mucl more value to me. I shall soon have anothe: case, and shall surely call at your Paten Agency to have it prepared. John Woodville. Chilicothe, Ohio, June, 1858. [We are gratified to receive this pleasan testimonial from our client, and to learn fron him that, in consequence of the care taken ii the drawing up of his claims, his patents are on this account, much more valuable to him It is notorious that inventors who undertak( the preparation of their own cases are gener ally not only bothered very much by the Patent Office before their claims can even be ex. amined, in consequence of defective papers but when they do succeed, it is rarely, if ever that their claims can stand a litigation.— Eds.
