Certificate of Patentability SECURED UNDER $10.000 BOND BY COLUMBIA BONDING CO. ACCORDANCE WITH ANNEXED BOND This is In Certify that we VICTOR J. EVANS & CO., Patent Attorneys residing at Washington, in the District of Columbia, have made a thorough examination of the U.S. Patent Office Records with,a view to ascertaining whether or not, in our opinion, a patent would be granted to more Desir Terrosiate for the invention of stove (INVENTOR SIGN ON THIS of and we hereby report the said invention patentable, and Guarantee that, if an application for patent on said invention be filed through us, we will upon the final rejection of the application by the Patent Office upon reference to prior United States Patents. refund upon demand of the applicant all fees paid us for the preparation and prosecution of the application, only excepting $5.00, and the cost of the Patent Office drawings. Given under our hand and seal this dav of A. D. 1900 EVANS BUILDING, WASHINGTON, D.C. SPECIAL NOTICE. If you have an invention which you desire to patent, fillout the blanks in this certificate with you name, residence, name of invention, etc., and forward to us with a model or sketch your device and a description of same will then make a search of the Records of the U.S. Patent Office in ordertodetermine if your invention is patentable. If w find we can obtain a patent for you we will then sign this Guarantee Certificate of Patentability and return the same to you together with our full report. If you file an application for patent through us. this guarantee will be worth the amount paid us for preparing and prosecuting the application in case we fail to obtain a patent under the conditions named therein. Benefits of Our Refund System. Our refund system is a combination of the equitable features of the advance fee system and the contingent, or "No patent, no pay" plan, both of which are objectionable in some particulars. Under the advance fee plan, the applicant pays the attorney's fee, and in the event of failure to secure a patent he loses the amount of such fee as well as the Government filing fee and the cost of the drawings, although in nearly all such cases the invention has been reported new and patentable by the attorney before the filing of the application. It is obvious that a contract to return the attorney's fee in case of failure to obtain a patent is a stimulus to thorough and careful work. There is absolutely no in- ducement, under our guarantee plan, for us to accept a case which does not contain patentable matter, as our entire work, both in preparing and prosecut- ing the application, would be a complete loss to us. The "No patent, no pay" plan has been the subject of unfavorable criticism by the Patent Office, and is against the interests of inventors in a very important particular. We refer to the temptation offered the attorney to accept an allowance upon meager and insufficient claims in order to secure and expedite the payment of the fees. PATENTS INSURED. The risk assumed by us under our refund system or plan is in the nature of an insurance against loss if the inventor's application be refused. This risk is found to be as follows: The annual reports of the Commissioner of Patents show that during the five years ending December 31st, 1900, the number of applications for patents, reissues, etc., was 209,852. Number of applications allowed, 138,438. Number of applications rejected, 71,414. One inventor out of every three, therefore, on the average, has his application rejected, and, of course, loses all he pays for Government and attorney's fee unless the risk be assumed for him. Under our system we lose less than I per cent of all the applications filed through us. This is the result of our careful searches and our policy of not advising the inventor to proceed unless we are positive that a patent can be obtained. THE COLUMBIA BONDING COMPANY is located at 615 F St. N. W., Washing- ton, D. C. and was organized expressly for bonding the certificates of patentability issued by VICTOR J. EVANS & Co. The officers of the company are David W. Gould, President and Victor J. Evans, Secretary. This Bonding Company is backed by over $70,000 worth of real estate in Washington, D. C., held by its officers and members. SECURITY OUR CERTIFICATE SECURED BY $10,000 BOND. Our signed certificate is an absolute contract which is legally inforcible by our clients in the event of our failure to comply therewith. Furthermore, as the certificate is an obligation which we assume toward our clients, the Patent Office would compel us to comply with its terms, or with any other agreement we might make with our clients. However, we have undertaken to more forcibly present the Absolute Security to the inventor, of our guarantee beyond all shadow of a doubt, and are, therefore, under bond to the Columbia Bonding Company in the sum of $10.000, SO that even in the event of failure on our part to comply with the strict terms of our certificate, our clients are Absolutely Protected Against Financial Loss, as the Columbia Bonding Company obligates itself to specifically and exactly carry out the agreement in the said certi- ficates. The financial standing of this Bonding Company may be readily ascertained, and our clients will, therefore, be satisfied that every possible contingency to protect them against financial loss has been provided for. Thus our clients are not only INSURED against financial loss but are also ASSURED through our well known skill and care in procuring patents, of obtaining Patents Which Will Thoroughly Protect The Inventor and Pay.
