Regulation and the circulation of knowledge: Penicillin patents in Spain Romero de Pablos, Ana History Antibiotics Penicillin Patents Circulation of knowledge Regulation Spain 1950s Historia Antibióticos Patentes Circulación del conocimiento Regulación España Década de los 50 This paper tells the early history of penicillin patenting in Spain. Patents turn out to be useful instruments for analysing the management of knowledge and its circulation in different professional and geographical domains. They protected knowledge while contributing to standardisation. Patents also ensured quality and guaranteed reliability in manufacturing, delivering and prescribing new drugs. They gained special prominence by allowing the creation of a network in which political, economic and business, industrial power, public health and international cooperation fields came together. The main source of information used for this purpose has been the earliest patent applications for penicillin in Spain between 1948 and 1950, which are kept in the Historical Archives of the Oficina Española de Patentes y Marcas. The study of these patents for penicillin shows their role as agents in introducing this drug in Spain. 2022-10-21T07:10:21Z 2022-10-21T07:10:21Z 2011 journal article Romero de Pablos, Ana. «Regulation and the circulation of knowledge : Penicillin patents in Spain».
