Not invented here : technology licensing, knowledge transfer and innovation based on public research

Using a new dataset encompassing more than 2,200 inventions made by Max Planck Society researchers from 1980 to 2004, we explore how licensee and technology characteristics affect the licensing and commercialization of technologies from public research. We find no evidence that spin-offs and external licensees systematically differ in their likelihood of successful commercialization. Technologies licensed to foreign firms are less often commercialized, which may reflect selection effects. Patented technologies and inventions by senior scientists are more likely to be licensed, but patent protection is related to lower commercialization odds and lower royalty payments. -- Licensing ; public research ; cognitive distance ; entrepreneurship ; Max Planck society
