Yieyie Yang Ph.D.


YieYie Yang focuses on complex patent litigation before U.S. district courts and inter partes review (IPR) proceedings in the chemical, pharmaceutical, and biotechnological fields. She has experience representing pharmaceutical patent holders in Hatch-Waxman litigations and has drafted numerous appellant and appellee briefs for pharmaceutical clients at the U.S. Court of Appeals for the Federal Circuit. Dr. Yang has handled various aspects of trial preparation, including general discovery, depositions of key witnesses, and motion practice, along with other pre-litigation due diligences such as analyzing global prosecution histories and patent strength, interviewing potential experts, and drafting position papers. She has been involved in numerous aspects of IPR proceedings, including developing key arguments, preparing and sitting in expert depositions, drafting expert reports and patent owner responses and motion papers, and preparing for oral arguments.

Dr. Yang's scientific background is in molecular and cancer biology. Her graduate research focused on identifying novel genes involved in axon guidance during the development of the nervous system, and her new findings were published in peer-reviewed scientific journals. During her post-doctoral research period at the Dana-Farber Cancer Institute, she studied epigenetic chromatin-remodeling complexes and identified tumor suppressor candidates that interact with oncogenes during cellular transformation and tumorigenesis.

While in law school, Dr. Yang also paid close attention to the development of Chinese intellectual property law. Her articles on Chinese patent law have been published by peer-reviewed law journals.
