We document the occurrence of process claims in granted U.S. patents over the last century. Using novel data on the type of independent patent claims, we show an increase in the annual share of process claims of about 25 percentage points (from below 10% in 1920). This rise in process intensity...

We study the causal impact of invalidating marginally valid patents during post-grant opposition at the European Patent Office on affected inventors' subsequent patenting. We exploit exogenous variation in invalidation by leveraging the participation of a patent's original examiner in the...

Skilled labor is a key input to the innovation process. A shortage in supply of skilled labor may hence impede … innovation activities, resulting in lower productivity gains. While governments are concerned about these likely negative impacts …, there is only limited empirical evidence whether and to what extent labor shortage affects innovation activities. The paper …
