David J. Stein (Dave)

Associate / Washington, D.C. Metro Office

David brings more than fifteen years of patent counseling experience to his clients in the software, computer and electrical industries. With a Master’s degree in Computer and Information Science and five years of experience as in-house counsel with the Cleveland Clinic, David appreciates the technologies that his clients are developing in the context of their business challenges and objectives.

David helps major clients identify and protect their innovative ideas. He counsels clients through technology review and harvesting sessions with the two-part goal of identifying the patent-worthy concepts in new products, platforms or workgroups, and then developing strategic plans to protect them. He also watches for and studies new developments in intellectual property law and advises clients about how such changes will affect their unique business challenges and specific patent applications.

  • Preparing and prosecuting patent applications directed to electronics and electrical engineering, including: processors, microarchitecture, storage, power, sensors, semiconductor fabrication and performance, and wireless communication.
  • Preparing and prosecuting patent applications directed to life science technologies, including: bioinformatics, medical devices and imaging, and electronic medical record (EMR) interfaces.
  • Appeals to the Patent Trial and Appeal Board, including pre-appeal conferences, appeal briefs, and oral arguments.

Before entering private practice, David served as patent counsel for the Cleveland Clinic. In this role, he reviewed invention disclosures, prepared novelty and freedom-to-operate opinions, and negotiated contracts with academic institutions and biotechnology companies.

David believes that sustained education in the technical arts is an important quality for effective patent prosecution. To this end, David is completing a Bachelor’s Degree in Electrical Engineering at George Mason University and intends to continue working toward a Master’s Degree. In his free time, David experiments as a hobbyist with new computing and electronics, including Python, 3D printing, machine learning, robotics, and single-board computers like the Raspberry Pi. He plans to teach his two sons about computer technology when they are a bit older.
