Marcus J. Jellen

OVERVIEW

Marcus Jellen is a Patent Agent at Haley Guiliano, where his practice focuses on drafting and prosecuting patent applications for pharmaceutical, biotechnology, and other life science clients. He works with clients in a wide range of technology areas in the life sciences, including small molecules, polymorphs, pharmaceutical formulations, polymeric materials, and protein therapeutics. Marcus is also experienced in IP portfolio development services such as competitive landscape analyses and freedom to operate searches.

Prior to joining the firm, Marcus worked as a Synthetic Chemist at Element Biosciences where he improved Next-Generation Sequencing systems by developing new dye scaffolds with specific photophysical profiles and improved water solubility. His work there also involved exploring unprecedented reactions on dyes that yielded multiple patents. Additionally, Marcus spent time at Intel Corp. where he worked as a chemical-mechanical-planarization engineer.

Marcus completed his Ph.D. at the University of California, Los Angeles, where he studied organic chemistry. His doctoral research focused on the design and synthesis of stimuli-responsive small molecules and materials. Before his Ph.D., Marcus obtained his B.S. degree in chemistry with a minor in physics from the University of Wisconsin–Milwaukee in 2015. While there, he researched the asymmetric synthesis of oxindole-based natural products such as Horsfiline. He also derivatized benzofuran-based NSAIDs destined to be opioid replacements.
