Roshan P. Shrestha, Ph.D.
ROSHAN P. SHRESTHA, Ph.D. is an associate in the Intellectual Property practice group in Taft’s Chicago office. He concentrates his practice in patent litigation, prosecution, counseling related to pharmaceutical, biosimilars, biotechnology, medical device, chemical products and electronic materials.
Roshan has broad litigation experience including district court litigation, contested AIA proceedings, e.g., Reexamination and Inter Partes Review (IPR) at the Patent Trial and Appeal Board (PTAB) in the United States Patent and Trademark Office (USPTO), International Trade Commission (ITC), and appellate matters.
Roshan has particular experience on issues arising under the Hatch-Waxman Act. He has expertise in developing strategies on issues of patentability, infringement, validity and enforceability. He has represented prominent generic and brand pharmaceutical companies at both the trial and appellate levels in matters involving: Silenor® (doxepin), Vyvanse (lisdexamfetamine dimesylate), Vimovo (naproxen/esomeprazole magnesium), Lyrica (pregabalin), Yaz (Drospirenone/Ethinyl Estradiol), Nexium (esomeprazole), Xarelto (rivaroxaban), Antara (Fenofibrate) and Rayos (Prednisone). Roshan also assists with the firm’s patent counseling and IP due diligence matters. He has extensive experience performing IP due diligence as part of corporate mergers and acquisitions, analyzing patent landscape, and preparing patent non-infringement and invalidity opinions.
Prior to joining Taft, Roshan was an associate at Leydig, Voit and Mayer, Ltd., a prominent IP boutique in Chicago. Before practicing law, he was a research scientist at Los Alamos National Laboratory in New Mexico, where his investigation on materials for hydrogen storage technology received a patent. His work received grant funding from the National Science Foundation, Department of Energy and NASA.
Roshan received his B.A. in chemistry, Phi Beta Kappa, from Grinnell College in 2001 and his Ph.D. from the University of North Carolina at Chapel Hill in 2006. He earned his J.D., cum laude, from Northwestern University School of Law, where he was a notes and comments editor for the Northwestern Journal of Technology and Intellectual Property.
Since 2014, Roshan has been recognized as a Rising Star by Illinois Super Lawyers. He was named one of the “40 Illinois Attorneys Under 40 to Watch” for 2016 by Law Bulletin, publishers of Chicago Lawyer magazine and the Chicago Daily Law Bulletin. Roshan volunteers at various Chicago non-profits and has served in the board of directors for Apna Ghar – Our Home, a Chicago non-profit that provides holistic services and conducts advocacy across immigrant communities to end gender violence.
