Jeff Stone is a registered patent attorney and came to Winthrop & Weinstine from a highly successful IP boutique, where he served as the Managing Partner. He serves as chair of the Patent Prosecution group.

Jeff’s legal expertise covers all things patent, including but not limited to: patent prosecution (domestic and foreign), patentability opinions, non-infringement opinions, diligence, litigation, licensing and strategic client counseling. He has worked on patent-related matters in a wide range of fields, including:

  • Atherectomy systems, devices and methods;
  • GPS guidance systems;
  • Pharmaceutical compositions and their use in treating CNS disorders;
  • Optical devices and systems;
  • Radar surveillance;
  • Fluid flow control;
  • Semiconductor structures and methods of manufacture;
  • Precision agricultural devices and methods;
  • Specialty films; and
  • Business methods.

Before becoming an attorney, Jeff worked in R&D, quality systems and regulatory affairs positions at large, international medical device companies, as well as a start-up medical device company. The breadth and depth of experience gained along the way affords Jeff an intimate knowledge of the industries he practices in, and further enables Jeff to quickly understand even the most complex inventions and easily relate with inventors to maximize patent protection. His industrial background in a range of positions provides Jeff with a unique insight into his clients’ businesses and strategies, allowing him to gain quickly, and maintain, the trust and respect of his clients.

Jeff’s industrial knowledge base covers various technologies, including: minimally invasive testing devices, in vitro testing methods and devices, testing hardware and software for analysis of analytes contained in fluids, glucose meters, software, applied algorithms and business methods, as well as a love of mechanical devices—a product of having grown up in a North Dakota farming community.

In addition, Jeff is a U.S. Army Veteran, having served during Operation Desert Storm and beyond.
