Managing IP writes about her: Julie Desrosiers “has got a real fighting spirit – she can rip apart a case. She focuses incredibly hard on the detail and offers in-depth analysis. She has a deep understanding of chemistry, and can take in very complex questions in this discipline. This is an essential skill, because you need to be able to explain it to a judge who doesn’t understand it at all.”
