Patent Law Reform INVENTIONS relating to foods and medicines are only partly the concern of the memorandum on patent law reform lately addressed to the Board of Trade by the Joint Chemical Committee. That committee consists of representatives of British chemical manufacturers (including ICI, the Distillers Company and Courtaulds), the Biochemical and the Chemical Societies, the British Association of Chemists, the Royal Institute of Chemistry, the Society of Chemical Industry, and the Wholesale Drug Trade Association. They agree to leave patents Such examples could be multiplied. Evidently for foods and medicines to be dealt with as at present modern methods of investigation and treatment are not provided by section 38A (3) of the Patents and Designs yet widely studied or applied, even in hospitals.

As to the improvement the general law the committee wants to see a reduction Commission on Population and the central laboratory of of the number of invalid patents granted (an invalid which the Family Planning Association hopes to set up in patent wielded by wealthy concerns has its own " nuisLondon should do much to promote a rise in standards. ance value ") and to see the Patent Office standard of validity harmonised with that which the law courts KEEPING PENICILLIN IN THE BODY apply. The committee also wants a new tribunal for THE systemic use of penicillin is still handicapped by litigants.

The wife received an ordinary pelvic examination. The husband’s semen, collected with faulty technique, was reported to contain no motile sperm, and on the strength of this he was given a course of injections of gonadotropins. Three months afterwards a second examination of sperm collected by a better method showed a more satisfactory result, but he was told he still needed a further course of expensive treatment. Actually in this couple the causes of sterility proved to lie mainly with the wife.
