Michael T. Piery, Associate

Mike Piery is an intellectual property litigator with a focus on patent litigation. He has litigated cases in many federal district courts, the U.S. Court of Appeals for the Federal Circuit, and the Patent Trial and Appeal Board.

His litigation experience consists of a full range of services, from pre-filing investigations through appeal, including:

• Conducting pre-suit due diligence investigations;
• Developing case strategies and managing discovery;
• Taking and defending depositions;
• Drafting pleadings, motions, and pre-trial briefings;
• Arguing evidentiary motions, claim construction, and dispositive motions; and 
• Drafting appeal briefs.

Mike works with diverse clients in a variety of technologies, including mechanical devices, medical devices, optical imaging equipment, telecommunications, software, snowplows, and product packaging.

Prior to joining Quarles & Brady, Mike applied his chemical engineering background to serve as a patent examiner at the U.S. Patent and Trademark Office for over five years. As a patent examiner, he reviewed applications across various technologies, including polymers, semiconductors, medical devices, fuel cells, chemical compositions, and plastics processing.

Drawing on his patent examiner experience at the USPTO, Mike has successfully represented patent owners and petitioners in post-grant proceedings before the USTPO’s Patent Trial and Appeal Board. The combination of USPTO and litigation experience allows him to advise clients on the merits and desirability of instituting proceedings before the USPTO simultaneous to pending district court actions and to advise clients on defending their patents during these parallel proceedings.   

Mike also counsels clients in intellectual property acquisition strategies, including design protection. His knowledge of both the process for acquiring patent rights and issues that may arise in litigation allows him to guide clients to optimal solutions that align with and advance their business objectives.
