Dr. Janet (Jian) Xiao, Ph.D., J.D., specializes in world-wide patent procurement, patent portfolio management, and strategic planning for life sciences companies.  Chambers USA and Chambers Global recognize her as being highly sought after for patent prosecution and strategy mandates by innovators from around the world.

Dr Xiao’s clients range from large multinational biopharmaceutical companies, such as Celgene, Genentech, and Bayer Healthcare, to emerging startup companies worldwide. She advises her clients on patent matters relating to various technologies including antibody therapeutics, cell therapeutics, nanomedicine, gene therapy, drug delivery systems, diagnostics, and nutraceuticals.

Recognized for her deep understanding of the industry and knowledge of IP, Janet is highly sought after for developing and strengthening her clients’ complex patent portfolios to maximize their commercial value and success. She is instrumental on the strategy development for multibillion-dollar patent portfolios for pharmaceutical clients, and adds tremendous value by combining her creative legal skills, keen business acumen, and solid foundation in science. As one client noted to Chambers, “Janet is very knowledgeable and the most efficient attorney with whom I have ever worked. She is able to balance historical knowledge of the portfolio with global prosecution issues.”

Dr. Xiao works extensively in performing IP due diligence reviews in the contexts of VC investments, technology transactions, mergers and acquisitions, as well as marketing and manufacturing clearance for biopharmaceutical products. She works with some of the world’s most sophisticated biopharmaceutical companies and investors in assessing potential risks and devising preemptive risk-management strategies for their product development and investments. She has led hundreds of IP due diligence projects, and is most notable for her deep knowledge about patent landscapes in the fields of cancer immunotherapy, gene editing, next-generation sequencing, liquid biopsy, antibody manufacturing, and medical devices. Dr. Xiao works synergistically with patent litigators in the event of legal challenges by third-party competitors or vice versa, and is frequently called upon to represent clients in litigation and post-grant proceedings.

Dr. Xiao is among the very few IP attorneys in the world who are both equipped with solid skills in global strategic IP management and knowledgeable about IP issues unique to China and Chinese clients, and she has been the go-to counsel for IP issues in U.S./China cross-border transactions and operations in China. As Chambers Global 2016 notes, “She is well-versed in acting for Chinese companies on U.S. related IP matters, especially in the biotechnology and pharmaceutical industries.” Chambers Global 2017 further praises her as an outstanding IP lawyer “who is renowned for her work on IP issues concerning complex cross-border transactions, where she regularly advises Chinese clients.”

Her IP expertise adds tremendous value to our business.”
