French patents as a source of information for chemical literature research have undoubtedly been the source of many a headache, if one can judge from the exasperated comments of Worischek 57) and Fleischer 27) nor can any encouragement be offered at this time.

Pharmaceutical compositions or medicines cannot be patented under French law, but the processes for manufacturing them are patentable. French patents do not extend to French Morocco, Tunis, Syria, or Lebanon which have separate patent systems. They do, however, extend to the other French colonies.
