Mr. Frueauf is an associate in the Biotechnology/Chemical Group where he counsels domestic and international clients on the preparation, prosecution, and management of complex worldwide patent portfolios. He is also experienced in the research and preparation of freedom-to-operate, validity, infringement, and patentability analyses.
In addition, Mr. Frueauf has experience in various inter partes matters, including district court litigation, interference work before the U.S. Patent and Trademark Office, and Section 337 investigations before the U.S. International Trade Commission. His work includes preparing strategy and analysis, motions practice, and case management for these matters.
Prior to joining Sterne Kessler, Mr. Frueauf was a Biologist at the National Cancer Institute where he studied the molecular signaling pathways related to programmed cell death using various molecular, biochemical, and proteomic technologies. He also assisted in the administration of phase II clinical trials related to ovarian cancer.
Mr. Frueauf's graduate work at Michigan State University as a member of the Starch Bio-Engineering Group focused on analysis of the structure/function relationships of the enzymes involved in starch and glycogen biosynthesis. His work included successful alteration of the catalytic activity and inhibitor specificities of these enzymes to affect the recombinant production of starch or glycogen molecules.
