university patenting

We examine ownership patterns of German university-invented patents before and after the abolition of the ‘professors' privilege’ in 2002 to explore how the legal change affected patenting activities. Our data show a shift from individually-owned and firm-owned patents to university-owned patents, which becomes increasingly strong over the years. Differences in the patent experience of inventors and universities further help explain the variance in ownership patterns. Both experienced and inexperienced inventors are affected by the legal change.
