The measurement of technical cohesion for patent pools and its applications

Abstract

Abstract: With patent pool becomes an important organization form of technical patents, the evaluation of patent pool is an urgent task. There are complicated relationships for the patent citations in patent pools. The technical cohesion index is proposed in order to quantitatively measure the technical cohesion of patent pool based on patent citations. Therefore, by utilizing the typical patent pools as research samples, the trend of technical cohesion is studied through the index. The results show that the technical cohesion is rising before patent pool formation. And the technical cohesion tends to be stable after patent pool formation. Patent pools could be divided into loose type and close type according to the values of technical cohesion index.

Key words: patent pool, patent citation, technical cohesion index, patent evaluation
