Of Counsel | Patent Attorney | Attorney at Law
Dr. Siepmann’s experience includes nearly fifteen years of preparing and prosecuting patent applications, preparing validity, freedom-to-operate and infringement opinions, negotiating and executing patent licensing agreements, as well as post-grant work such as patent interference proceedings.
Dr. Siepmann’s legal experience began at small and medium-sized IP boutique law firms in Salt Lake City, Utah and the Washington, D.C. metropolitan area. At these firms, Dr. Siepmann’s practice focused on patent preparation and prosecution in genetics, material chemistry, polymer science, biologics (monoclonal antibodies and recombinant proteins), cellular immunology, virology, as well as various applications of classical biochemistry. Here, Dr. Siepmann also gained experience protecting innovations in the pharmaceutical field (compositions and methods of manufacture), the personal care industry (consumable products), and industrial chemistry (large scale organic chemistry).
Dr. Siepmann also has experience working at the large, general practice, domestic law firms Thompson Coburn, LLP and LeClairRyan, LLP where he served as Counsel and Partner. His patent drafting and prosecution work there focused on antibody technology, vaccine compositions, CAR-T therapy, cancer therapies, and neurological indications. In addition to his law firm experience, Dr. Siepmann was Director of Intellectual Property at Affymetrix, Inc. (now Thermo Fisher Scientific) in Santa Clara, California, where he managed global patent portfolios and played a key role in various corporate intellectual property matters. In addition to drafting patent applications in the fields of small molecule chemistry, nucleic acid chemistry, genetics, diagnostics, microparticle technology, lithography and photolithography, silica chip technology, and laboratory tools, Dr. Siepmann drafted and negotiated numerous patent licensing agreements, as well as scientific collaboration agreements, consortium agreements, and common material transfer and non-disclosure agreements.
Throughout his career, Dr. Siepmann sought opportunity to diversify his experience to provide him with a broad background in IP law. This broad training provides him with the capability of tackling almost any general question from the numerous disparate realms of intellectual property law. Working nearly a decade and a half at various law firms and a major biotechnology company, coupled with a diverse scientific training spanning over thirteen years, well equips Dr. Siepmann to assist with almost any intellectual property issue, especially in the fields of chemistry and biology.
