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.

Classifying Patents by Different Criteria

Many uses of patent data for research and policy analysis require relating them to a meaningful unit of analysis or classifying them according to particular criteria. By relating or classifying patents in this manner, information can be obtained on these specific units or on the economic or social relevance of certain variables. Analysis may require relating patents to the entity that filed them, to the individual who made the underlying invention, to a particular field of technology, a particular industry, a particular region or a particular institutional sector.
