Dan Hall

Attorney, Shareholder

Dan Hall is an experienced litigator who represents clients in a wide range of trials and appeals in state and federal courts. Dan excels at taking complex fact patterns and legal arguments and crafting concise, logical and persuasive arguments to present to courts and juries. Clients benefit from Dan’s extensive trial experience, which includes jury and bench trials involving patent infringement, trustee liability, breach of contract, partnership and shareholder disputes, employment termination, and usurpation of business opportunities.

 

In 2020, Dan was named an Attorney of the Year by Minnesota Lawyer for his work as part of the defense group that defeated a $42 million breach of fiduciary duty claim in a complex trust case following a 20-day trial. Dan’s experience trying both patent infringement and business claims makes him uniquely well-suited to handle business disputes concerning intellectual property issues, patents and trade secrets.

 

Dan focuses on the most efficient strategy to obtain the results his clients want from the beginning of a case through discovery, dispositive motion practice and trial. He has also served as the primary drafter of briefs filed with the Sixth Circuit, Eight Circuit and Federal Circuit Courts of Appeals, as well as the Minnesota Court of Appeals that resulted in favorable decisions for his clients.
