Silver - Firms: prosecution

Silver - Firms: litigation

The IP team at Aird & Berlis LLP and Aird & McBurney LP works together seamlessly to provide a service that is “not only business minded, but timely and budget friendly. It is a go-to firm in Canada”. Its Toronto-based line-up is a good one, with a strong prosecution group being formed by Kimberly McManus, Lola Bartoszewicz, Erica Lowthers and Kitt Sinden. McManus represents numerous organisations that are leaders in their industry. She offers a variety of services that make a difference, including prosecuting patent applications, managing global portfolios and conducting due diligence. Essential to her clientele’s success, Bartoszewicz is a superb project manager who understands the business criticality of patents and balances every action with a commercial vision. “Erica has a wealth of knowledge and is always ready to take on new projects. She articulates all options in detail and develops strategies, while keeping in mind the constraints of her clients’ business.” While providing creative and actionable ways to advance patent applications is the bread and butter of Sinden’s practice, he also has a lot of experience advising on pharmaceutical patent litigation, including proceedings brought under the new Patented Medicines (Notice of Compliance) Regulations (PM(NOC)). Overseeing the outfit’s litigation efforts, Timothy Lowman has over 42 years of experience under his belt. “Tim is always the best-prepared person in the room. Pragmatic and approachable, he knows the facts and presents extremely complex issues in a straightforward manner. Working with him is simply wonderful.” He is joined by Amy Grenon, “the definition of grace under fire. She is always professional, calm and persuasive when guiding patrons through difficult decisions, and is seen as a leading member of the IP bar who is well liked and respected by her peers.” “Amy uses her science background to provide practical advice in very technical cases and couples this incredible expertise with a business-minded lens, which is invaluable for clients.”
