Patent pools have become a prominent mechanism to reduce litigation and encourage the production of new technologies. This paper takes advantage of a window of regulatory tolerance under the New Deal to investigate the effects of pools that would form in the absence of effective anti-trust. Difference-in-differences regressions of patents and patent citations across 20 industries imply a 14 percent decline in patenting for each additional patent that is included in a pool. An analysis of the mechanism by which pools discourage innovation indicates that this decline is driven by technologies for which the creation of a pool weakened competition.
