OECD Patent Statistics Manual

This 2009 edition of the OECD Patent Statistics Manual takes stock of the recent developments in the field. It provides guiding principles for the use of patent data in the context of S&T measurement, and recommendations for the compilation and interpretation of patent indicators in this context. It aims to show what patent statistics can and cannot be used for, and how to count patents in order to maximise information on S&T activities while minimising statistical noise and biases. Finally, it describes how patent data can be used in the analysis of a wide array of topics related to technical change and patenting activity including industry-science linkages, patenting strategies by companies, internationalisation of research, and indicators on the value of patents.

Indicators of Patent Value

The term “patent value” has several different meanings. It can mean the economic “private” value to the holder, defined as the discounted flows of revenue generated by the patent over its lifetime. It can mean the “social” value of the patent, that is, its contribution to society’s stock of technology. The two concepts are closely related, as the revenue generated should be commensurate with the technological contribution, but they are not identical, as part of the social value is not appropriated by the patent holder (there are externalities): the published knowledge for instance can be used by other inventors and/or competitors to improve on the initial invention.
