Abstract
This paper analyzes the average effect of academics inventors on the technological importance of firms’ patents. Drawing on a database of Swedish academic patents, a quasi-experimental design is employed by matching firms’ academic and non-academic patents on a set of patent characteristics. The findings point to a negative effect of academic inventors on the technological impact of firms’ patents. Results moreover show a positive effect of academic inventors on the generality of firms’ patents, indicating a more widespread impact. The persistence of firms’ academic patents, measuring the extent to which patents’ knowledge is spread and retained in subsequent inventions, also show a positive effect of academic inventors. The findings suggest that firms on average involve academics either for assisting in problem-solving activities or for technology development.
