Abstract
Empirical research has found a discrepancy between the perceived importance and the actual level of information on competitor's R&D strategies. It has been argued in the literature that patent information might be used to overcome this information deficit. However, empirical research further reveals that patent information is rarely used in strategic R&D planning. The present paper explores this issue and introduces two types of patent portfolios for strategic R&D planning. In patent portfolios on the company level, patenting strategies are identified and the quality of overall technological positions is benchmarked against relevant competitors. In addition, we present a patent portfolio on the technological level, which, as it is known from various technology portfolios, helps companies to manage the allocation of R&D resources effectively. Based on patent data from 21 German, European and Japanese mechanical engineering companies we show the application of both patent portfolios for strategic R&D planning purposes. The patent portfolios prove to be a very valuable tool for R&D decision makers in companies. Based on the experiences made in the case study, recommendation for the effective use of patent portfolios are formulated.
