About Yixin H. Tang

Yixin Tang combines a creative and assertive litigation style with a superb technical training in his legal practice focusing on intellectual property litigations. He has represented some of the largest generic pharmaceutical companies in the world as well as smaller companies in numerous complex Hatch-Waxman (“Paragraph IV”) litigations. He has also drafted formal opinions on patent evaluation and Paragraph IV notice letters on different types of drug products.  Yixin has also represented patent owners (individual inventors as well as large corporations) in asserting their intellectual property rights against some of the largest corporations in the world.

A trial lawyer by training and experience, Yixin has spent substantial in-court time, including examining witnesses at trial and arguing substantive motions, and gained in-depth knowledge on all phases of litigation. He has fine-tuned his practice to adapt to the various business, regulatory, and legal needs the clients may have. He has the ability to understand quickly the big picture as well as specific issues in the case, develop an efficient and effective litigation strategy from the start, and form and lead a team to execute the plan. Yixin is particularly adept at gaining insights into expert witnesses’ various technical expertise, understanding how the experts’ expertise fits into the legal strategy, and formulating strong arguments that are both legally and technically sound. More important, Yixin understands that the clients’ needs and concerns go beyond the particular litigation proceeding at hand, and has had extensive experience advising clients in developing and achieving their goals.

Prior to attending Harvard Law School, Yixin obtained a Ph.D. in Molecular Biology and Microbiology from Tufts University, taught microbiology at Brandeis University, and underwent post-doctoral training at the Whitehead Institute for Biomedical Research in Cambridge, Massachusetts. Yixin’s research interests involved plasmid vector engineering, microbe-host interactions and microbial pathogenesis, vertebrate embryonic development and the regulation of genes involved in signal transduction.

Yixin is an avid duplicate bridge player and competes frequently in national and regional tournaments. He enjoys travelling with his family to off-the-beaten-path locations all over the world.
