Ms Desrosiers regularly acts on behalf of high-tech corporations and advises clients on injunctions, seizures and proceedings to protect their intellectual property, trade secrets and strategic information.

Ms Desrosiers’ practice is currently focused almost exclusively on patent litigation. A seasoned litigator, she has been involved in several important patent infringement cases in the pharmaceutical sector. She appeared before the Supreme Court of Canada on behalf of the International Federation of Intellectual Property Attorneys and has served as counsel during various patent infringement cases, ranging from helicopter landing gear to complex chemical molecules used to manufacture drugs. She has also acted in major copyright disputes resulting in precedent-setting decisions.

Widely sought for her opinion on issues concerning the patent linkage system, Ms Desrosiers often delivers seminars on patent litigation and is recognised for her expertise by Chambers, the Canadian Legal Lexpert Directory and the IAM Patent 1000. She was recently listed in IP STARS Top 250 Women in IP.

Chambers Canada mention that Ms Desrosiers “is respected for her impressive ability in international patent litigation.” One source emphasised: “She put in one of the best performances I’ve ever seen in the Supreme Court. She is particularly knowledgeable on patent protection issues in the pharmaceuticals and technology sectors […].”

Ms Desrosiers is a member of Fasken’s board of directors.
