Jessica Chao counsels clients in pharmaceutical patent prosecution matters, including application drafting, US and foreign patent prosecution and clearance, and patentability studies. She has extensive knowledge is the areas of organic chemistry and medicinal chemistry. 

Prior to joining Wolf Greenfield, Jessica was an associate at an intellectual property firm in New York, where she assisted clients in patent prosecution matters on technologies including medical imaging, software, telecommunications, and medical devices. At Boston College, her graduate research centered on x-ray crystallography studies analyzing the structure of archaeal enzymes bound to organic solutes. As a medical chemistry intern at Gilead Sciences, Jessica evaluated synthetic organic routes toward analogs of novel hepatitis drugs for pharmacokinetic studies. Jessica’s undergraduate research involved organic synthesis projects on Hasubanonine, a potential analgesic, and Moenocinol.

  • Prepared and prosecuted patent applications for inventions within the fields of biotechnology, medical devices, software, and telecommunications. Wrote search reports for portfolio analysis and opinion matters.
  • Conducted research for ANDA and trademark litigation cases, and performed patentability and novelty searches for patent opinion matters on biotechnology, pharmaceutical, and mechanical art inventions.
  • Drafted memoranda analyzing invention validity and patentability for patent opinion matters.
  • American Bar Association
During law school, Jessica served as Notes Editor for the Cardozo Arts & Entertainment Law Journal, in which her Note on the Section 271(e)(1) Safe Harbor of the Hatch-Waxman Act was published.
