The present Master thesis was written during an internship at Deutsche Post DHL Solutions& Innovations, a subsidiary of Deutsche Post DHL. The main purpose was to make a patent portfolio benchmark for the previously identified business competitors of the DPDHL group. The research questions aimed to find out how relevant the patent portfolio analysis is for comparing competitors and whether or not the results can be matched with other types of rankings. The benchmark was made using the PatentSight software tool. PatentSight allows the patent portfolio analysis of individual companies as well as groups of companies (competitors). The software tool is based on a new approach to benchmark patent portfolios called Patent Asset Index. This approach uses several indicators to measure the patent portfolios strengths. The indicators are based on relatively widely used measures of patent analysis such as the number of citations that a patent has received. However, these measures are further adjusted by the PatentSight indicators in order to prevent false results due to the difference in patents’ ages, for instance. The results of the patent portfolio benchmark and their comparison with other rankings have confirmed previous research findings that the patent portfolio analysis is a useful tool which can remove uncertainties and provide new perspectives but cannot be used as single indicator of the competitors’ strength.
