Defensive Publishing An Empirical Study
AbstractDefensive Publishing denotes publication of an invention with the purpose of creating prior art, and thus preventing patents being granted on this invention. Although widely employed, it has hardly been investigated empirically. Our study is based on 56 in-depth interviews, among others with most industrial firms in the German DAX 30 stock index. We find that 70 percent of the companies in our sample use defensive publications, for up to one third of their inventions. Interestingly, we find that the patent system itself is frequently used for defensive publishing. Our findings also challenge contributions connecting defensive publishing to patent races.
