During the period of Fourteen Years which has elapased since the business of procuring patents for inventors was commenced by MUNN & Co., in connection with the publication of this paper, the number of applications for patents in this country and abroad has yearly increased until the number of patents issued at the United States Patent Office last year (1859) amounted to 4,538; while the number granted in the year 1845—fourteen years ago-numbered 502—only about one-third as many as were granted to our own clients last year; there being patented, through the Seien-tlfic American Patent Agency, 1,440 during the year 1859. The increasing activity among inventors has largely augmented the number of agencies for transacting such business. In this profession, the publishers of this paper have become identified with the universal brotherhood of Inventors and Patentees at borne and abroad, at the North and the South; and with the increased activity of these men of genius we have kept apace up to this time, when we find ourselves transacting a larger business in this profession than any other firm in the world. We may safely assert that no concern has the combined talent and facilities that we possess for preparing carefully and correctly applications for patents, and attending to all business pertaining thereto. FREU EXAMINATION OF INVENTIONS. Persons having conceived an idea which they think maybe patent-able are advised te make a sketch er model of their invention, and submit to us, with a full description, for advice. The points of novelty are carefully examined, and a reply written corresponding with the f acta, free of charge. Address MUNN & CO., No. 37 Park. row. New York. PRELIMINARY EXAMINATIONS AT THE PATENT OFFICE. The advice we render gratuitously upon examining an invention does not extend to a search at the Patent Office, to see if a like invention has been presented there, but is an opinion based upon what knowledge we may acquire of a similar invention from our long experience, and the records in our Home Office. But for a fee of $5, accompanied with a model or drawing and description, we have & special search made at the United States Patent Office, and a report setting forth the prospects of obtaining a patent, ire, made mp and mailed to the inventor, with a pamphlet, giving initructions for further proceedings. These preliminary examinations are made through our Branch Office, corner of F and Seventh streets, Washington, by experienced and competent persons. Over 1,500 of these xaminations were made lastyear through this office, and aa a measure of prudence and economy, we usually advise inventors to have a preliminary examination made. Address MUNN Ac CO., No. 37 Paik-row, New York. CAVEATS. Persons desiring to file a caveat can have the papers prepared on reasonable terms, by sending a sketch and description of the invention. The government fee for a caveat is $20. A pamphlet of advice regarding applications for patents and caveats furnished gratis on applicatien by mail. Address MUNN & CO., No. 37 Park-row, New York. HOW TO MAKE AN APPLICATION FOR A PATENT. Every applicant for a patent must furnish a model of his invention, if susceptible of one; or if the invention is a chemical production, he most furnish samples of the ingredients of which his composition is composed for the Patent Office. These should be securely packed, the inventor's name marked on them, and sent, with the government fee, by express. The express charges should be prepaid. Small models, from a distance, can often be sent cheaper by mail. The safest way to remit money is by draft on New York, payable to Munn & Co. Persons who live in remote parts of the country can usually purchase drafts f rora their merchants on their New York correspondents; but if not convenient to doeo, there is but little risk in sending bank bills by mail, having the letter registered by the postmaster. Address MUNN & CO., No. 37 Park-row-New York. Circulars of information concerning the proper course to be pursued in obtaining patents in foreign countiies through onr Agency the requirements of the different Patent Offices, Arc., may be had gratis upon application at our principal office, No. 37 Park-raw, New York, or either of our branch offices.
