David W. Harlan

An experienced trial and appellate attorney, David Harlan prosecutes and defends civil actions on behalf of entities and individuals in a broad range of IP and business disputes.

Much of David’s current practice involves intellectual property matters such as patent and trademark infringements, trade secret disclosures and patent antitrust issues. He is also experienced in handling commercial and contract disputes, fraud and breaches of fiduciary duty, RICO, securities and white-collar crime investigations.

David often counsels clients regarding antitrust matters. As lead trial counsel in an antitrust case, he represented a manufacturing company in a 56-day jury trial where he secured a $105 million judgment.


Prior to joining the firm, David was head of litigation at a full service commercial firm and then headed the litigation practice at an intellectual property boutique.

Earlier in his career, he served as First Assistant U.S. Attorney in the Eastern District of Missouri responsible for prosecution of major criminal cases and the defense of the government in major civil cases. This experience gives him added perspective in matters related to price fixing, government program fraud, mail fraud, false statements and other business-related criminal charges.
