Alexandra Cavazos, PhD - McDermott Will & Emery


Alexandra Cavazos, PhD, focuses her practice on patent prosecution and intellectual property in the life sciences, using her expertise in biochemistry and molecular biology to help companies maximize the value of their US and international IP portfolios.

Alexandra also has significant Hatch-Waxman litigation experience in the small molecule space, as well as PTAB litigation experience relating to large molecules. This litigation experience informs her patent prosecution strategies, allowing her to draft claims that are broad enough to encompass competitors’ products while also being strong enough to survive legal scrutiny.

Alexandra earned her JD from the University of California at Los Angeles and her PhD from the University of California at Berkeley, where she successfully determined the three-dimensional structure of a membrane-bound signalling molecule involved in the pathogenesis of Mycobacterium tuberculosis, the bacterium responsible for causing tuberculosis in humans.
