Mike also has advised clients on hundreds of patents in the context of acquisition due diligence, license negotiations, and non-infringement/invalidity analyses. He has also led successful licensing campaigns to monetize patent portfolios he has helped create. Mike is also a patentee himself, having obtained U.S. Pat. No. 10,939,269 covering a unique public display system he invented.

A graduate of West Point, Mike served overseas in the U.S. Army Corps of Engineers for several years.
