I have enjoyed a wide range of experience in patent and other intellectual property litigation covering a broad range of technologies including electrical, mechanical and chemical cases.  The thread connecting these litigations and my experience in patent prosecution and related corporate issues is creative problem solving.  I enjoy working within legal, financial and practical bounds to help clients reach near and long term goals.. In addition to my basic goal of serving my clients, I hope to bring along the next-generation of service-oriented, creative lawyers.. While my specialty is patent litigation, I am frequently involved in complex patent prosecution, patent-related corporate transactions, as well as copyright and trademark issues, and IP licensing.  I am also involved in a significant amount of antitrust counseling and litigation issues, which is generally, but not exclusively, IP-based.

I am an experienced attorney who specializes in the protection of software and related intellectual property. These specialties are a natural evolution of a 20-year first career in the software field.. In my early years as a software engineer, I developed arcade games, home-computer games, robotics and other real-time control software, combat simulation software, and all kinds of device drivers and utilities. I also held executive positions in several mid-size technology companies and I owned two small software engineering firms.. From that base of engineering and business experience, I am able to offer knowledgeable advice on a variety of technical and business issues. I am just as comfortable in court as I am in a boardroom, a high-tech lab, or garage workbench.. As a litigator, I am involved in all aspects of software patent and copyright disputes, from pre-suit investigations through expert discovery, motions practice, settlement negotiation, trial, and appeal. My cases have involved many different computer-related technologies, including object linking and embedding, vehicle interface and control systems, variable data printing, network monitoring, digital music, and navigation.. As a transactional attorney, I draft and prosecute patent applications, file copyright registrations, and prepare many different kinds of agreements relating to the protection of technology and intellectual property. I have also prepared opinions covering patent validity, enforceability and infringement. My technical subject matter experience includes real-time control systems, games, combat simulators, telecommunications, language compilers and translators, database management systems, and business methods.. Before joining Berenzweig-Leonard, I was a litigator and patent attorney with Cloudigy Law. Before that, I was a litigator at Crowell & Moring, and a patent attorney at Kenyon & Kenyon (now Andrews Kurth Kenyon).. On the side, I love to study cognitive psychology, particularly the mechanisms that underlie human reason, persuasion, perception, and belief. I am an active member of the West Springfield chapter of Rotary International. And on weekends, you can often find me riding my Harley on the back roads of Virginia.
