TREATISE 女 ON PATENT ESTATE, COMPREHENDING NATURE, CONDITIONS AND LIMITATIONS OF INTEREST IN LETTERS PATENT. BY THOS BOHALL, OF THE CLEVELAND BAR. CLEVELAND: INGHAM, CLARKE & CO., LAW PUBLISHERS. PREFACE. For some time past, my attention has been drawn to the following features of Patent Law, attractive in relief from its routine practice. Developed outcome of notes, thus originally made from time to time for personal reflection, is here given. The material character of the premises, and the importance of the issues, led to placing the subject-matter in this published form. THOS. B. HALL. Cleveland, Mar. 15, '88. |
