Before forming IdeaLegal, Mike spent more than six years as in-house counsel for Adidas. There, he designed and implemented the company’s first comprehensive strategy for protecting its iconic Three-Stripe trademark in North America. Mike built a trial team by identifying and coaching key witnesses from senior members of the company’s design, marketing, sales, product development and R&D groups.

That team eventually won a verdict against Payless ShoeSource—the largest trademark verdict in U.S. history. Mike’s other major wins at Adidas included favorable resolutions with formidable litigation opponents, including Wal-Mart, Target, KMart, Skechers, Steve Madden, J. Crew and Kenneth Cole. 

Before joining Adidas, Mike worked as an associate with the prestigious intellectual property group of Kilpatrick Stockton LLP. There, he honed his outside counsel skills and understanding through the protection of national and international brands, including marks owned by Anheuser-Busch, General Mills, Harley-Davidson, and the Estate of Martin Luther King. These matters involved wide-ranging and complex issues such as the protection of a motorized sound, combating private-label knock-offs, and protecting the name and likeness of a social and political icon. 

Mike is an active presenter and opinion leader, and he regularly presents intellectual property seminars for various trade associations, law schools, and state bar organizations. 

Mike received his Juris Doctor degree from Duke University and his Bachelor´s degree from the University of Michigan.
