What do you focus on?

I work with technology clients to help them develop and implement IP and business strategies that are tailored to their business needs. This includes developing IP that protects a company’s products and services, as well as, helping corporate leadership to understand the risks and the compliance obligations associated with bringing their products to market.

I regularly work with clients to develop and implement business processes for identifying and protecting their IP. I have extensive experience helping clients navigate their competitive landscape through freedom-to-operate counseling and assisting clients with strategic acquisitions including technology and data licensing.

A significant portion of my practice involves advising US, multinational, and non-US companies on various aspects of regulatory compliance including US export controls and sanctions compliance. This includes advising clients on US export controls, conducting export compliance assessments, and obtaining export control classifications and licenses for products. This comprises a wide range of products and services including defense technology, software products and services, electronic products, networking and telecommunication products and services, medical devices including imaging and diagnostics, life sciences products and therapies, and industrial products.

My practice also involves advising companies that receive government funding for technology development and helping them to understand and comply with the Federal Acquisition Regulations (FARs) relating to the development of IP with government funding.

When I am not practicing law, I serve as the chairman for the Water Management Advisory Committee of a local municipality and help to develop water management and sustainability policy.
