Who’s who legal states that “no list of good patent juniors would be complete without Isabel”. Recent highlights include appearing as junior counsel for Actavis in the Supreme Court in the landmark case on the law of claim scope and equivalents (Actavis v Eli Lilly [2017] UKSC 48) and representing Unwired Planet in the first FRAND trial in this jurisdiction (Unwired Planet v Huawei [2017] EWHC 1304).
