Peter J. Prommer

Peter Prommer advises technology-focused businesses, from emerging companies to leading global corporations, on how to strategically build and protect intellectual property portfolios that align with their business objectives. This includes counseling on enforcement, licensing, patent, trademark, and general IP matters.

What do you focus on?

My practice focuses on protecting, leveraging, and defending clients’ intellectual property rights.

With my prior experience in 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 that align with their business objectives. This includes counseling clients on patents, trademarks, IP portfolio development, and competitive intelligence, as well as opinion and enforcement matters.

My patent counseling experience includes developing and executing effective strategies for global patent portfolios in mechanical, electronics, software, and materials science technologies. I further advise clients on opinion and post-issuance matters, including enforcement, inter partes review, and other post-grant proceedings. Technologies I have provided counsel on include wearable devices, digital health care solutions, medical devices, micro-fluidic systems, computer hardware, networking systems, software-based systems, optical systems, imaging systems, propulsion systems, battery systems, consumer goods, composite materials, packaging systems, and infrastructure systems.

I further advise foreign entities on various business issues as they consider furthering their activities into the U.S. market.

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 efforts 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.
