Stephen W. Chen

Stephen Chen is a patent agent in the Patents group. He focuses his practice on intellectual property protection and counseling for life sciences technology clients.

What do you focus on?

I leverage my science background in molecular biology and biochemistry to advise clients in obtaining protection for their intellectual property assets. I work with research universities, hospitals and biotechnology companies seeking to develop and maintain an intellectual property strategy. This further includes obtaining patents on behalf of clients, providing guidance on their intellectual property portfolios and those of their competitors.

Regenerative Medicine | Stem Cells

I have research experience with stem cells and specific experience in the patenting of regenerative medicine technologies in the U.S. and foreign countries. I regularly interact with leading stem cell experts to learn of the latest developments in this technology field and consult regularly with foreign lawyers on ethical issues related to stem cell patenting.

Nanotechnology | Molecular Detection

I also focus on micro- and nano-sized devices that are used for molecular detection. These technologies rely on not only biological, but chemical and electrical innovations for medical and biotechnology research applications.

What do you see on the horizon?

I believe that the breakthroughs and benefits of regenerative medicine will deliver dramatic improvements to personal health and become critically important for an aging society.
