Yuri Chumak is a lawyer, patent agent and trademark agent, based in Toronto and serving a regional, national and international clientele.

Yuri’s team operates a paperless office with a state-of-the-art case management system to assist the flow of work. We file patent and trademark applications electronically with the Canadian Intellectual Property Office (CIPO) to secure instant filing dates for those applications. We file Patent Cooperation Treaty (PCT) patent applications electronically as well. For IP litigation matters, we serve and file Court documents and other materials electronically where possible.

We assist clients with IP strategy, including IP portfolio management, as well as IP litigation, IP / technology agreements and transactions, and advertising, marketing and related regulatory matters. We routinely assist the clients of non-lawyer agents as well as lawyers who do not practice in our areas of expertise, respecting those referrals.
