Das Monitoring von Patentportfolios soll Basispatente und Umzäunungsstrategien der Pioniere sowie Umzingelungsversuche des Wettbewerbs aufdecken. Der vorliegende Beitrag stellt mit dem Patent-Chart eine Patentabbildung auf Basis der Zitatdarstellung als neues Konzept für das Strategie-Monitoring vor. Im Gegensatz zu den bekannten Verfahren wird es ermöglicht, alle Patente in einem komplexen Technologiefeld simultan im Netzwerk ihrer Zitatbeziehungen zu analysieren und die zeitliche Entwicklung zu erfassen. Als Grundlage der grafischen Betrachtung liegt dem vorgestellten Patent-Chart die Bedeutung sämtlicher Patente eines Technologiefeldes und die strategische Relevanz ihrer Zitatbeziehungen zugrunde. Der Patent-Chart kann zur periodischen Überwachung des Patentportfolios und als Informationsgrundlage der strategischen Planung der Patentpolitik verwendet werden. Das Verfahren zeigt Stärken und Schwächen der Patentbasis der Unternehmen in einem Technologiefeld auf, analysiert die Patentpolitik der Wettbewerber im Detail einzelner Patente und gibt Hinweise auf mögliche M&A-Partner. (English Summary: The monitoring of patent portfolios should uncover basic patents as well as fencing and surrounding attempts. The present article introduces with the Patent Chart a patent illustration, based on the citation visualisation, as a new concept for strategy monitoring. In conflict to the known procedures it is made possible to analyse simultaneously all patents in a complex field of technology, in the network of their citation relationships, and to record their chronological developments. The foundation of the graphic examination is based on the uncovered Patent Chart, the importance of all the patents in a technological field, and the strategic relevance of their citation relationships. The Patent Chart can be used for repeated monitoring of the patent portfolios and as basic information for the strategic planning of patent politics. The procedure points out strengths and weaknesses of the patent base of the company in a field of technology, analyses the patent politics of the competition in detail of individual patents, and advises on possible M&A partners.)
