Peter J. Prommer

Peter Prommer is a partner in the Intellectual Property group and is a member of our Life Sciences Industry team. He advises small growing companies to leading global corporations on how to develop and protect their intellectual property assets.

What do you focus on?

Leveraging my past experiences in university research and as a licensed professional engineer with an international engineering consulting firm, I understand the creative and problem solving processes in the development of intellectual property. I counsel clients on implementing effective intellectual property strategies that include value-enhancing solutions. In addition to advising U.S.-based companies, I also assist foreign entities on various business issues as they consider furthering their activities into the U.S. market.

Intellectual Property Strategies

I work with clients to devise effective strategies, both foreign and domestic, for building and strengthening their intellectual property portfolios in a manner that aligns with their business objectives. This includes counseling clients on patents, trademarks, IP portfolio development and competitive intelligence, as well as opinion and enforcement matters.


I execute effective strategies for procuring U.S. and foreign patents in software, mechanical, electromechanical, and materials science technologies. I further work with clients on opinions, as well as post-issuance matters including enforcement, inter partes review, and other post-grant proceedings. My representative experience includes a variety of technologies such as wearable devices, digital healthcare solutions, software-based systems, microfluidic systems, medical devices, optical systems, imaging systems, propulsion systems, battery systems, consumer goods, composite materials, and infrastructure systems.

What do you see on the horizon?

Patent-eligible subject matter continues to be an issue, particularly for software and computer-implemented inventions. This area of law continues to evolve following the Alice Corp. v. CLS Bank ruling by the Supreme Court and the ongoing attempts by the Federal Circuit to interpret the decision. I continue to analyze patent protection strategies that minimize risk in this area to allow companies to more effectively grow their intellectual property.
