Marks & Clerk, a leading international intellectual property law firm, has had a presence in Ottawa for over 100 years, with our first Canadian office opening in the national capital region in 1921. Previously located on Kent Street, we are pleased to share that we have now moved to new modern offices on O’Connor Street.
The new office space is located in the heart of the business and legal district and features an innovative design to facilitate collaborative working for our team in a modern and welcoming environment with technology and amenities to support hot-desking and hybrid working. We are proud to have partnered with local Ottawa interior design consultants Parallel 45 Design Group.

This new state-of the art office on O’Connor Street is part of a long-standing commitment to invest in our people and strengthen our footprint in the national capital region, and to build deeper connections within Ottawa's vibrant business community.” - James Baker, Ottawa Office Managing Partner, Marks & Clerk.
