A gravitation model similar to that used for the simulation of international trade flows was constructed for international flows of patent applications and these flows were estimated on a log-linear basis over a period of several years in respect of a number of countries. In modified versions of this model, various potentials which could significantly affect the numbers of ‘active’ and ‘passive’ patent applications beyond national frontiers were used in the gravitation model at a national level. GNP-related elasticity of flow of patent applications was shown to be far greater than 1 both in the patent filing countries and in the receiving countries. As anticipated, the distance-related elasticities were lower than in the case of international trade in physical products but nevertheless highly significant. With regard to the basic model, preferences ofvarying strength for patenting beyond national interpreted. The estimates produced by the model for 1967, 1971 and 1975-78 permitted correlations studied.

As a result of the replies received, only seven centres are now supplied with patent documents, six of those on a more extensive basis than previously, while nineteen other libraries provide means of identifying required documents.

The paper provides also statistical data for 1978 and 1979 about the ownership of Canadian patents and for the period of 1972 to 1979 about the number of patents with Canadian inventors, broken down according to the SIC of use.

Taking whaling as an example the article analyses the problems of validity that arise when patent statistics are used as an indicator of technological change in a particular industry. The results show that in this industry the patent statistics are a reliable indicator of technological development.
Renker, H. Progress report on the establishment of a patent information centre (Informationszentrum Patente) in the Federal Republic of Germany. World Patent Information 3(l), 23-25. The author describes the structure of the sectorial information centre for patent information (12 17) which is being established in the Federal Republic of Germany as central information service under the responsibiliry of the German Patent Office. The local patent information services will be incorporated in the system. Details are further given on the work of the user’s working party 17, which since April 1980 has taken part in the planning of the information centre by the German Patent Office.
