Jim serves as the Chair of Brooks Kushman's applied physics practice group as well as the Co-Chair of our chemistry practice group. With over 15 years of patent prosecution experience and degrees in chemistry, biotechnology, electrical engineering and physics. Jim has extensive experience in a broad range of industries that spans across many products and technologies. 

Jim has a special focus working with universities, representing technology transfer departments on protecting and monetizing their inventions. As a former adjunct professor and researcher, Jim has a deep knowledge of both sides of this relationship. He works closely with professors and inventors on drafting and prosecuting patent applications. Due to his wide-ranging educational background, he is able to work with professors on a variety of technologies.

Jim has substantial experience in a variety of chemical technologies, including novel organometallic compounds, polymer science, and thin film chemistry. He has an extensive technical background in organic chemistry, and he has worked with clients in the chemical and pharmaceutical industries in areas such as small molecule therapeutics; drug formulation and drug delivery technologies; and chemical process technologies. Technical areas of Jim’s patent prosecution work also includes various sub-fields of physics including solid-state physics, optics, electricity and magnetism, mechanics, atomic and molecular physics. Other technologies include medical resonance imaging and image processing, circuit design, and optical communication. His prosecution and opinion work include medical and diagnostic devices and all areas of biotechnology (such as cell and molecular biology and biochemistry). Specific examples include methods of treating human and animal disease; diagnostic assays; biomarkers; pharmaceuticals; diagnostic agents; blood analysis methods; food processing techniques and compositions; and biofuel technologies.

With almost 20 years of experience in the laboratory setting before entering the field of patent law, ‎including research in semiconductor films, ‎Jim applies his considerable technical experience to the procurement of patents, both ‎foreign and domestic, and to assist in client counseling and patent portfolio management. His deep understanding of an inventor’s work language allows him to draw out the essential information required to obtain patents with excellence. In addition to preparing and prosecuting patent applications, Jim consults clients on developing patent portfolio strategies and preparing freedom to operate opinions, particularly in relation to the chemical and electrical arts.

Jim has graduate degrees in chemical physics, physics, biotechnology, and electrical engineering. Prior to joining Brooks Kushman, Jim worked as a research scientist and technical specialist at a large automotive OEM for ten years. In this role, he was awarded fourteen patents in thin film technologies and co-authored several scientific articles. Jim has also been an in-house patent attorney at Pfizer and an adjunct professor of chemistry at Wayne State University.
