We develop and apply a set of measures that enable a fine-grained characterization of technological capabilities based on the CRC database. These measures can capture the distance between any two patents, and help to identify outlier patents. They also provide a rich characterization of a firm’s technological footprint, including its depth and breadth. The measures also enable researchers to assess the technological overlap, similarity, and proximity of the technological footprints of two or more firms. At the level of the macro technology landscape, the measures can be used to explore such dynamics as technology agglomeration, knowledge spillovers, and technology landscape evolution. We show applications of each of the measures and compare the results obtained with those that would be obtained with previously existing measures of firm diversity, similarity and proximity, highlighting the advantages ofthe measures used here.
