Managing IP recognized her as a “Top 250 Women in IP” worldwide—one of only 60 attorneys ranked in the U.S.—and as a “Patent Star.” Benchmark Litigation also named Christine a “Top 250 Women in Litigation” and an intellectual property “Litigation Star,” and IAM Patent 1000 ranked her as a leading patent lawyer.
