Patents and the success of venture-capital backed startups : using examiner assignment to estimate causal effects
Abstrakt
I study how patents affect firm success (initial public offering or acquisition at a high price) in a sample of 2,191 U.S. startups applying for patent protection in the 24 months following their first round of venture capital funding. I observe both successful and unsuccessful patent applications and use a measure of patent examiner leniency as an instrument for getting patents.
I find a positive effect of patents on firm success for life science firms but not for information technology firms.
