Handbook of Patent Law, OF ALL COUNTRIES. BY WM. P. THOMPSON, C.E., OF THE FIRM OF W. P. THOMPSON & BOULT, AGENTS FOR PROCURING PATENTS, FIFTH EDITION REVISED. LONDON: STEVENS & SONS, 119, CHANCERY LANE, D. VAN NOSTRAND, 23, MURRAY STREET, AND 27, WARREN STREET. 1882. Entered according to Act of Congress, in the year 1878. By W. PHILLIPS THOMPSON, in the Office of the Librarian of Congress at Washington, All rights reserved. ODLEIAN LIBRARY 13 JUN 84 OXFORD PREFACE. ENCOURAGED by the kind favour with which the public has treated the previous editions of this Work, the Author has again carefully revised and considerably added to its contents, so as to give the law and practice of each country exactly as they stood at the end of 1881. He has again to thank the various foreign correspondents of his firm for their kind assistance in supplying him with all the latest amendments in the Patent Laws of the various countries. Modes of procedure in actions at law are not herein set forth, as in such cases the patentee should be governed by his solicitor: similarly, a description of the routine required in obtaining Patents in the various countries is omitted, as this would be solely interesting to the Patent Agents. The Costs of securing Patents are inserted in each case. These are only approximate, being the average charges usually made in the profession; and may be relied upon as fair rates for Patents of ordinary type. They are also substantially those charged at the British and International Patent Offices, 323, High Holborn, W.C., London, and 6, Lord Street, Liverpool. |
