Brian Daley is a Montreal-based patent litigator who has been practising for over 25 years. He has particular experience in regulatory matters and litigation involving mechanical, medical device and pharmaceutical patents. More recently, Brian has become involved in arbitration in the pharmaceutical field. He is known to support clients by "inspiring confidence through years of expertise" and "controlling the courtroom." An opposing counsel once observed that Brian is "better prepared than any other lawyer he faces in Court." These are a few of the reasons why Brian is asked to act as lead counsel on complex patent litigation and has been recognized as one of Canada's leading lawyers in this area. 

Prior to studying law, Brian worked as an engineer for four years. In addition to helping him understand complex technology, it instilled his systematic approach to litigation. Brian uses legal project management to track budgets and report monthly to clients. He also sets up collaboration portals directly with clients to share information and provide up-to-the-minute information on the status of files.

Brian led a team that obtained an important victory in the Federal Court of Appeal in defence of a patent infringement action against a Canadian company specializing in dry eye diagnosis and management. The ensuing decisions are often cited for their precedential value on  interlocutory injunctions and patent validity. While Brian has led many successful cases before the courts, he understands that resolving disputes at opportune moments and on favourable terms is often a better solution than a trial.   

Brian is a frequent presenter to professional organizations and companies as well as a contributor to publications in the intellectual property and regulatory fields in North America and Europe. He supports the United Way as co-chair of the firm's annual campaign and is involved in the firm's management.
