The firm as a whole and our noted practitioners received the following accolades:

Delivering the full scope of trademark services, Aird & Berlis LLP | Aird & McBurney is a popular choice for a range of brand owners, who appreciate its attentive and client-focused approach. In recent years, the firm has made a concerted effort to grow and, in 2021, Millman IP’s entire practice joined the group, bolstering its trademark prosecution offering. It also received contentious reinforcement in the form of … lawyer Amy Grenon. The WTR 1000 newcomer “is superb with clients and translates complex matters into easy-to-understand advice. Amy is a delight to work with as opposing counsel and always sees to it that her patrons achieve favourable outcomes.” She works closely with Grant Cansfield, a commercially minded lawyer and trademark agent who always dispenses business-relevant advice. He manages the Canadian portfolio for [an] American Fortune 200 company … as well as supporting their M&A practice, with Ken Clark. “Ken is a seasoned and practical litigator, who can take the files all the way to trial while also delivering a beneficial result.” Setting the tone from the top is the venerable Timothy Lowman. He knows exactly how to maximise the value of intangible assets, and has recently been doing just that for an American multinational mass media company.
