As a past president of Banner Witcoff and member of the firm’s Board of Directors, Chuck understands the business needs of his clients. He focuses his practice on patent prosecution and counseling matters, offering clients valuable insight as a former patent examiner with more than 20 years of legal experience.

Chuck — who was recognized on Crain’s Chicago Business’ 2019 Notable Gen X Leaders in Law list — represents clients ranging in size from start-ups to multinational companies on a variety of patent matters primarily in the electrical, computer and business method arts. He helps clients strategically create and manage their patent portfolios, and prepares product clearance, infringement and validity opinions. He has prosecuted patent applications globally, and counsels clients on a variety of international intellectual property issues.

Leveraging his experience as a former patent examiner, Chuck navigates clients through all phases of prosecution of patent applications before the U.S. Patent and Trademark Office. He’s prepared and prosecuted patent applications in many different technologies, including those related to electronic circuits, computer hardware, digital rights, operating systems, Internet and e-commerce, cellular telephones, telephone and computer networks, medical devices, satellite communications, video conferencing, set-top boxes, securities trading systems, and a variety of business methods.

Among his other professional accomplishments, Chuck recently served on a Banner Witcoff team that scored a major victory for a telecommunications company. The team filed dozens of inter partes review petitions in the highly-publicized matter, leading the Patent Trial and Appeal Board to invalidate multiple patents in the company’s favor. Chuck served as president of Banner Witcoff from 2011-13 and 2016-18, during which time he led the firm through a significant period of growth and strategic planning involving diversity and rebranding initiatives.
