When you take the gender gap in science, technology, engineering and math fields and multiply it by what you find in Big Law it equals up to something like this: A 2022 study in the North Carolina Law Review found that 87.4% of patent arguments before the Federal Circuit over the previous decade were handled by men. The study also found men handled more than 90% of patent arguments before the U.S. Supreme Court over the prior 30 years.

The intellectual property litigation practice at Sidley Austin, where 40% of the partners are women, looks pretty remarkable by comparison. Four of the team’s five global co-leaders—Ching-Lee Fukuda in New York, Aimee Fagan in Dallas, Stephanie Koh in Chicago, and Irene Yang in San Francisco—are women. (The fifth co-leader is partner Jeff Kushan in Washington, D.C.)
