Sidley’s Ching-Lee Fukuda is a founding member of the Lead Counsel Summit, an initiative dedicated to increasing the representation of women in first-chair positions in #IP cases.   Ching-Lee's commitment to this cause is featured in a recent article, "Would-Be Competitors Come Together to Increase the Number of Women Sitting First-Chair in IP Cases." The piece highlights LCS’s goal to ensure that 25% of its graduates serve as lead counsel within two years of completion—a testament to minimizing gender parity in the legal field.   The inaugural Lead Counsel Summit is taking place this weekend, and will bring together an esteemed group of #womeninIP, including Sharon Lee—an IP Litigation partner based in Sidley’s New York office.
