An inventor consults you, stating that he has discovered, after applying for a patent, that a French work to be found on the shelves of the reference libraries in the colony contained (unknown to the inventor) full specifications and plans of his invention; otherwise, as far as the inventor knows, he is the first and true inventor. Can the patent, if granted, be attacked on the ground of prior publication ? 6. A applies for a patent for an article patentable under ordinary conditions, but the identical article was produced some fifty years ago by a person who kept the method of manufacture secret, and whose secret died with him. Is A entitled to a grant of Letters Patent ? 7. Define what constitutes utility in a patent, and indicate in your answer what degree of utility is necessary to support a patent. 8. A consults you stating that he has been working on a patent jointly with B as joint investigators and discoverers. B refuses to either join in applying for a patent or to assign his interest in the invention to A, and A asks you to advise him as to his position as an inventor and as to his rights, and how same can be best protected. How would you advise Aas to his position ? and give your reasons for the advice given. 9.

What special points require attending to in drawing the claim in a specification for a combination patent ? 5. The following were the facts in two well-known cases of actions for infringement in which the validity of the plaintiff's patent was questioned : In the first the patent was for crinolines, and the invention consisted in the substitution of steel springs for whalebone and other elastic materials. In the second the patent was for an improvement in electric lamps : the claim was for " the combination of a carbon filament within a receiver made entirely of glass, through which the leading wires pass, and from which receiver the air is exhausted, for the purposes set forth " : substantially the same lamp had been constructed in two previous instances, the only change made by the plaintiff being the substitution of a carbon filament for a carbon rod, with the object and effect of producing high resistance to the electric current (and corresponding intensity of light), with great durability. What was the decision in each of these cases as to the validity of the patent ? What were the grounds of the decisions ? Discuss the principles applicable. 6. What are the objects of lodging a provisional specification? With what degree of particularity must a provisional specification be drawn ? 7.
