Banner Witcoff Expands Life Sciences Practice with New Attorney and Patent Agent

Banner Witcoff is pleased to announce that it has expanded its life sciences practice with the addition of attorney Zhengyu Feng, Ph.D. (Feng), and patent agent Bronwen Loeb, Ph.D., to their Washington, D.C. office.

Both Feng and Bronwen join from Faegre Drinker, following the addition of Mercedes K. Meyer, Ph.D., who joined the firm in July.

Feng brings 15 years of experience focusing on patent prosecution and opinions in the life sciences industry. He advises clients on preparing and prosecuting patent applications, including the management of worldwide patent portfolios.  Feng also brings insights into IP practice in China as co-chair of the AIPLA IP Practice in China committee.

His doctorate in medical sciences/microbiology and a degree in biochemistry from the University of Nebraska Medical Center and Fudan University, respectively, provide him with a well-rounded understanding of complex scientific research, which is critical for performing portfolio valuation and diligence on patent portfolios.

Bronwen is a Massachusetts Institute of Technology (MIT)-trained biologist, where her research focused on protein-DNA interactions and protein structure-function analyses.  Her scientific training supported her work examining complex biological subject matter, initially as a United States Patent and Trademark Office (USPTO) examiner and subsequently as a law firm patent agent. 

Bronwen brings over 20 years of experience in patent prosecution in the biotechnology, chemistry, and pharmaceutical industries.  She advises clients seeking and protecting U.S. and foreign patents, including the management of worldwide patent portfolios.

Banner Witcoff has a rich history in the practice of patent law dealing with biotechnology sciences issues. Our attorneys include practitioners with doctorate degrees and others with advanced degrees and substantial experience in all phases of life sciences and pharmaceutical practice. These qualifications give our attorneys the ability to collaborate with both bench scientists and in-house counsel.
