In the previous Chapter we have examined the pattern of specialization of advanced countries across technological fields described by IPC classes, on the basis of patenting in the US, at the EPO, in West Germany and France. The consistency shown by most countries in their profiles of specialization emerging from patents registered in different foreign institutions is documented for the first time and the findings add new depth to our undestanding of the areas of strength and weakness of major countries.
