Dr. Joshua Quinn specializes in preparing and prosecuting domestic and international patent applications in the fields of biotechnology and other life sciences. He works closely with his clients to understand their scientific assets and file applications aimed at securing U.S. and foreign patent rights and building a strong patent portfolio. He also performs due diligence assessments. Joshua has technical expertise in molecular biology, microbiology, immunology, genetics, antibodies, infectious disease and synthetic biology. His multidisciplinary scientific training enables him to quickly understand and communicate complex scientific concepts within these fields.

Prior to joining Womble Bond Dickinson, Joshua worked as a patent agent at a large international law firm, where he gained valuable experience in patent counselling and prosecution. Working with clients and firms around the world, he became proficient at overseeing global patent portfolios of various clients.

Before that, Joshua was a Tufts IRACDA postdoctoral fellow in the Department of Molecular Biology and Microbiology at the Tufts School of Medicine. In this role, he conducted research examining molecular and cellular interactions between infectious microorganisms and their hosts to understand human disease. He also taught medical microbiology, mentored junior scientists in the laboratory and served on the department DEI committee. Joshua has held numerous leadership positions throughout his scientific career, has presented talks at leading conferences in his field and has authored multiple peer-reviewed publications focusing on molecular microbiology and human disease.
