Andrew ShaughnessyTorys

The Toronto-based IP team at Torys concentrates on lifecycle management for its clients products, providing guidance on potential loss of market exclusivity and responding to IP disputes. One standout recent matter saw IP group chair Eileen McMahon and head of IP litigation Andrew Shaughnessy acting for Horizon Therapeutics in proceedings before the Patented Medicine Prices Review Board concerning allegations of excessive pricing. Andrew Bernstein has extensive litigation experience across all facets of IP, while on the transactional side, coordinator of the group, Edward Fan, is the key contact, honing his focus on the acquisition, exploitation and enforcement of IP. Teresa Reguly is particularly formidable in the biotechnology and medical device industries, and from a strong all-women pool of junior lawyers, counsels Nicole Mantini and Yolande Dufresne are particularly integral to the practice; the former due to her prominent reputation among North American and international pharmaceutical companies and the latter owing to her risk management and regulatory capabilities..
