National Academy of Inventors fellow Dr. Glenn Prestwich has over 45 years of experience as a professor, entrepreneur, and biotech startup C-suite executive. His breadth of chemical expertise comprises organic synthesis, natural products chemistry, medicinal chemistry, mechanistic enzymology, agricultural chemistry, chemical biology, and biochemistry. He’s been involved in intellectual property litigations that concern medical devices, diagnostics, new pharmaceuticals, drug delivery, agrochemicals, and consumer products.

Dr. Prestwich brings to all legal and technical cases a deep appreciation for how chemistry informs the invention and development of products that offer solutions to problems in the life sciences and medicine, ranging from disease detection and treatment to tissue healing and regeneration.

Dr. Prestwich has been a prolific inventor since 1977, and an expert witness in IP law cases since 2007. He is an inventor on over 95 patents and patent applications, including 48 issued patents.

As an expert witness, Dr. Prestwich enjoys the challenges of dissecting the validity (or invalidity) of patents in litigation. He appreciates the subtleties of claim construction and works collaboratively with attorneys to identify successful arguments based on sound science and legal principles.

He has drafted over 39 expert reports, declarations, and affidavits in support of his attorney clients. He has been deposed 18 times and testified in Court four times.

Dr. Prestwich posts video blogs that target both experts working with attorneys, and attorneys seeking experts. These are on his website at clearsolutionsbiomedical.com

Dr. Prestwich says: “In the courtroom, the role of an expert witness is to educate the court. I help the judge and jury understand that my expert opinion is accurate, compelling, and the only correct conclusion that one can reach.”

Dr. Prestwich is an organized, clear, and effective writer. He has written over 50 single-author scientific publications, reviews and book chapters, and is co-author on over 610 additional peer-reviewed articles in the scientific literature. His publications encompass areas such diverse topics as anti-cancer drugs, gels for wound repair, cell therapy, and regenerative medicine, insect and pest control agents, cholesterol-lowering agents, lipids and cell signaling tools, and anti-inflammatory agents.

He has also been a prolific writer of grant proposals, with over 80 funded grant proposals in over 47 years, both from his academic laboratories at Stony Brook and Utah, as well as SBIR/STTRs for the more than eight startup companies that he co-founded since 1990.
