Mark C. Zimmerman, JD, MSEE, BSEE

As a founding member of Hanley, Flight & Zimmerman, I have experience in U.S. and foreign patent prosecution and client counseling with particular emphasis in the electrical and mechanical fields. In addition to patent prosecution, my experience includes directing post-grant proceedings in the USPTO and acquisition negotiations. Additionally, I’ve rendered numerous non-infringement and invalidity opinions as well as testified at trial.

I’ve worked with technologies including, among other things, mobile telephones, networks, semiconductors, remotely-readable meters, industrial equipment, spray nozzles, kitchen fixtures, and firearms.

Before starting a legal career, I worked as a design engineer at Motorola Cordless Products, specializing in RF and audio circuit design. I earned my JD from DePaul University College of Law, with honors. I also earned an MS in Electrical Engineering and Computer Science from University of Illinois, Chicago, and my BS in Electrical Engineering, magna cum laude, from Marquette University.

In 2023, I was Recommended for Patent Prosecution by the IAM Patent 1000 and was designated a Patent Star in the United States (national) and Illinois from Managing IP’s IP Stars, an annual guide to the top intellectual property attorneys in Illinois and nationwide. IP Stars Read Here
