We analyze how frivolous patent-infringement claims made by non-practicing entities (NPEs, or "patent trolls") affect startups' ability to grow and create jobs, innovate, and raise capital. Our identification strategy exploits the staggered adoption of anti-troll laws in 32 U.S. states. The laws...

We provide evidence on the value of patents to startups by leveraging the quasi-random assignment of applications to examiners with different propensities to grant patents. Using unique data on all first-time applications filed at the U.S. Patent Office since 2001, we find that startups that win...

We show that the acquisition of a startup inventor's first patent has a negative effect on the subsequent productivity of the patent's inventor, leading to 6.7 fewer patents being granted to the inventor over five years. This effect is not due to the inventor focusing on high-quality...

Motivated by concerns that the patent system is hindering innovation, particularly for small inventors, this study investigates the bright side of patents. We examine whether patents help startups grow and succeed using detailed micro data on all patent applications filed by startups at the U.S....
