Juan Zheng is an associate in the life sciences and litigation practice groups at COJK. She focuses her practice on patent prosecution in the areas of chemistry, pharmaceuticals, biomedical technology, catalysis, and spectroscopy, and provides litigation support in these areas. She also provides support to the firm's Hatch-Waxman ANDA litigation practice. Juan is a specialist in polymer, organic, inorganic, and biological chemistry. She also has experience in materials chemistry, such as paper and pulp production and related materials.

Juan works with clients in all phases of development, from startups to large corporations, conducting freedom to operate and patentability searches, providing patent-related opinions, and assisting with patent portfolio evaluation and management; she has also represented clients at oral hearings at the Patent Trial and Appeal Board. Juan provides technical support in litigation in the areas of materials, organic, and polymer chemistry; and has worked on detailed invalidity opinions and re-examination proceedings.

Prior to becoming an attorney, Juan served as a graduate research assistant at Massachusetts Institute of Technology, where she co-authored a book chapter on conjugated polymers in chemosensing and biosensing. After MIT, she worked at a Boston-area intellectual property law firm for seven years, first as a technology specialist, then a patent agent, and then after receiving her J.D., as an associate.

Juan received her J.D. from Suffolk University Law School in 2010. She received her Ph.D. in organic chemistry from the Massachusetts Institute of Technology in 2005, and her B.S. in bioorganic chemistry from the University of Toronto in 2000. Juan is fluent in Mandarin Chinese.
