About Nancy Pei

Nancy Pei is counsel in Smart & Biggar's Toronto office, and every file is a life sciences file, mostly pharmaceuticals and biologics. Innovative drug and biotech companies turn to Pei both when a patent dispute lands in court and when they need advice on how patent, regulatory and pricing rules shape a product's life.

Before law, Pei trained as a pharmacist, finishing a pharmacy degree at the University of Toronto in 1991 and staying on for an LL.B. in 1995. The call to the Ontario bar came in 1997. Registration as a trademark agent followed in 1998 and as a patent agent in 2004, and Pei still holds registration as a pharmacist with the Ontario College of Pharmacists.

Chambers Canada ranks Pei for intellectual property litigation, singling out the work for major drug makers in significant patent disputes.

Pei's also a regular voice on the law in this field. The firm's monthly Rx IP Update newsletter has had Pei as its editor since it launched in 2001 (co-editor since 2023), and Pei's presented the IPIC Patent Case Law Review session on anticipation three years running. In 2022 Pei was elected to the board of BIOTECanada, the national biotech industry association.
