Note. —In this paper " the Act " means " The Patents, Designs, and Trade-marks Act, 1908." 1. What are the requisites of a valid patent ? What is meant by " disconformity " and by " utility " in patent law ? 2. What is the meaning of " invention," and of " the true and first inventor " as defined in the Act? The possessor of an invention dies before making an application for a patent for his invention. Can a patent for the invention be granted to any person, and, if so, to whom, and subject to what conditions ? 3. What is the difference between a provisional and a complete specification ? What must a complete specification contain ? A, B, and C apply jointly for a patent for an invention upon which they hope to improve. Describe what steps you would take to obtain for them a patent. 4. Your client with his application for a patent lodges only a provisional specification : in what time thereafter must, — (a.) A complete specification be lodged ; (b.) The complete specification be accepted ; (c.) A patent be sealed ? How would you proceed if the period allowed for the lodging of the complete specification had been allowed to expire without a complete specification being lodged ? 5. When does a patent take effect ? After the acceptance of an application for a patent with which only a provisional specification has been lodged an infringement of the patent is committed. What steps would you advise the patentee to take for his own protection ? 6. A license is granted by a patentee to A, authorizing A to manufacture and sell the patented article in a certain town. B, a rival manufacturer in that town, infringes the patent by manufacturing and selling similar articles. What remedy, (if any) has A against B ? A exceeds the authority given him by the license by selling the patented article in another town. The patentee thereupon revokes the license and sues A for infringement. A counterclaims on the ground that the patent is invalid. Can A succeed in his counterclaim ? Give reasons for your answer. 7. What is the meaning of " mechanical equivalents " in patent law ? What is meant by a " master " or " pioneer " patent, and what are its advantages ? 8. What rights has a patentee against the Crown ; and what rights has the Crown against the patentee ? State the procedure for obtaining an extension of the term of a patent, and the principles upon which such an extension is granted.
