About Belmore Neidrauer LLP

Belmore Neidrauer LLP is a Toronto intellectual property litigation firm founded in 2009 by Neil Belmore and Lindsay Neidrauer, whose surnames give the firm its name. It's built around patent litigation and patent opinion work, with a smaller trademark litigation practice alongside. Clients include multinational pharmaceutical and technology companies such as Janssen, Pfizer, Bayer, Eli Lilly, AbbVie, and Takeda, and the firm notes that virtually all of its cases have a cross-border element, coordinating strategy with counsel in other jurisdictions. Beyond the courtroom, the firm prepares patent validity and infringement opinions and advises clients on patent strategy before a dispute ever starts.

The firm's lawyers appear before the Federal Court, the Federal Court of Appeal, and the Supreme Court of Canada. Belmore Neidrauer represented Janssen at the Supreme Court in Pharmascience Inc. v. Janssen Inc., a case on the patentability of medical treatment methods that the Court decided in July 2026, dismissing the appeal and confirming that Janssen's dosing regimen claims were patentable subject matter. The firm has also been listed by Legal 500 Canada, recognized by Chambers Canada for intellectual property litigation, and ranked Tier 1 for intellectual property law by Best Law Firms Canada.
