摘要

We analyze how frivolous patent infringement claims made by nonpracticing 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 US states. The laws lead to a 4.4% increase in employment at high-tech startups-an increase driven by IT firms, a frequent target of NPEs. Increased access to financing, both venture capital and patent-backed lending, is a key channel driving our findings. Measures aimed at curbing the threat posed by NPEs can thus help reduce the real and financing frictions faced by startups. (C) 2019 Elsevier B.V. All rights reserved.
