Jennifer A. Marles focuses her practice on helping clients develop and manage their intellectual property assets, particularly patents. Her focus is on clients in the life sciences space, including those involved in developing novel medical devices, chemical compositions, biologics and pharmaceuticals. She also assists clients to protect mechanical devices, and with contracts relating to their IP, including copyright and licensing issues relating to software. Jennifer also provides clients with opinions on issues such as patentability, trademark registrability, and freedom-to-operate.

Jennifer’s clients include a broad range of early stage and established companies and universities. She has helped her clients to patent inventions such as safety syringes, natural pesticides, new formulation technologies, and building components on a global basis. Jennifer has filed many provisional and PCT applications, and has assisted clients with optimizing their intellectual property protection strategy globally, including in China in conjunction with Chinese counsel.

She was awarded the Law Society Gold Medal for graduating at the top of her class in 2006 at the University of Victoria, and also received the J. Edward Maybee Memorial prize for earning the highest mark overall on the 2009 patent agent’s qualifying examination.

Starting her career in IP law with Oyen Wiggs as a summer student in 2004, Jennifer returned as an articled student in 2007, and then as an associate in 2008. She became a partner of the firm in 2015. Jennifer has served as an adjunct professor at the Peter A. Allard School of Law at the University of British Columbia since 2008, where she lectures on copyright law.
