Michael focuses his energy on developing and implementing patent and other IP protection strategies for companies in growth and maturity phases. In this work he uses different combinations of his experience with patent litigation, IP asset acquisition, patent prosecution, portfolio strategy, and licensing to meet individual clients’ particular needs. While his work has heavily focused on patents, he also handles trademark and copyright matters.

He represents clients enforcing patent rights and those defending against infringement allegations. He has been a central cast member in a number of patent litigation and licensing matters, including patent monetization campaigns, which include the full range of post-prosecution work. Technologies covered by these litigation-focused matters include medical devices, biotechnology, pharmaceutical, and high tech devices. 

In his prosecution and licensing work, Michael has worked on portfolios including technology for refrigerators, copiers, displays, electric car batteries, stents, farm implements, and apparatuses for manufacturing semiconductor chips and drying powder. He has also worked on remote control technologies and airplane braking systems.  

Michael served as an Extern to the Honorable Brook Hedge of the D.C. Superior Court and as a Law Clerk in the office of the Public Defender in Rockville Maryland. Michael is committed to the firm’s Pro Bono practice and works with DC Legal Aid to help individuals and families facing eviction proceedings.  More information about Michael’s Pro Bono work can be found in the Mintz Levin Pro Bono Journal.
