[Penicillin: from discovery to patenting the large-scale production process].

This article examines discoveries, inventions, and innovations related to penicillin by sampling activities to solve technological problems which can be traced by the distribution of scientific articles, government reports, innovations, and patents between 1929 and 1945, and proposes reflection on the importance of scientific progress for national security. The analysis highlights the technological trajectory and outcomes in the area of intellectual property, considering US policy implemented to catalyze innovation and provide institutional conditions to meet national defense needs as an important factor, although this did not necessarily imply a unique solution in other contexts.
