Deeth Williams Wall LLP is a small, specialized law firm based in Toronto's financial district at 150 York Street. It was founded over 30 years ago by four lawyers, Douglas Deeth, Gervas Wall, Marijo Coates, and Amy-Lynne Williams, who left larger firms to build something different. As the firm puts it, the founders believed "there had to be a better way to treat our clients, our lawyers and staff." The practice has grown from its original seven lawyers to about twenty.
The practice concentrates on intellectual property, technology, and regulatory law. That covers patent, trademark, copyright, trade secret, and industrial design work, along with information technology matters such as artificial intelligence, privacy, cybersecurity, and Canada's anti-spam law. On the regulatory side, lawyers at the firm advise on food and drug, medical device, natural health product, cosmetics, and telecommunications rules, and its litigators handle patent and trademark disputes, including pharmaceutical patent cases under Canada's Notice of Compliance regulations. Clients range from Canadian technology start-ups to multinational corporations, provincial government bodies, and healthcare institutions, across industries that include pharmaceuticals, food, chemicals, automotive, and retail.
