32This article examines the role of gender in patent inventors’ collaborations and
individual productivity. We study how the time needed by an inventor to eventually
become a “star” relates to their portfolio of female and male coinventors,
characterised in terms of gender, career seniority and productivity. Our empirical
analysis applies different survival models to a sample of almost 100k inventors
debuting in 2000 and all their patenting peers, followed over a period of 20 years.
We find that being female and having female coinventors is correlated to a longer
time to become star and that is not a matter of homopily. Seniority is also correlated
to a longer time, while having a star among coinventors to a shorter time, in
particular for female inventors. These findings confirm the presence of a relevant
gender bias and suggest a potential beneficial mentoring/role model mechanism
with stars being a strong catalyst of other stars, especially when among women.
