Preemption games are widely used to model patent races, innovation adoption and market entry problems. A previously neglected feature of these problems is that the agents� states (e.g. R&D firms' �technological improvements) are kept secret and stochastically change over time. We fully characterize equilibrium in preemption games where private information evolves according to Poisson processes, and provide a strategic rationale for the common wisdom that �big things happen fast.� In the context of patent races we surprisingly find that strengthening patent rights need not increase innovation disclosure. Furthermore, we clarify a basic welfare trade off between duplication costs and preemption: the former likely take place in early stages of the race, and preemption in later stages.
