Secrets for sale? Innovation and the nature of knowledge in an early industrial district: the Potteries, 1750-1851

This paper investigates innovation and knowledge in the North Staffordshire Potteries during the eighteenth and early nineteenth centuries. It evaluates new empirical evidence of formal and informal patterns of knowledge creation and dissemination in order to highlight tensions between forms of open knowledge sharing and the appropriation of returns to innovative activity. By presenting new patent data it shows that formal protection was not a widespread strategy in the industry. It uses patent specifications to determine what specific types of knowledge were, and could be, patented in the district, and by whom. A range of sources are used to demonstrate evidence of innovation and knowledge appropriation outside of the patent system. The paper identifies distinct types of knowledge in the industry and shows how differences in these led to a range of strategies being employed by potters, with the role of secrecy highlighted as a particularly prevalent and effective strategy.
