Updating a patent filing after co-founder exit and IP assignment — Canada

Looking for general process guidance on a patent matter following a co-founder separation. Not asking for legal advice, just trying to understand typical steps and what questions to bring to a patent agent.

Background: I am the primary founder of a small Ontario corporation. My co-founder voluntarily stepped down in early 2026. We have a mutual release and IP assignment agreement that she is expected to sign shortly, which assigns all her right, title, and interest in all patent applications and related filings to me.

Patent question: A patent application was filed in connection with the corporation's product while we were collaborating. Now that she has assigned all IP to me through the exit agreement, what is the correct process to update the patent record? Specifically:

— Do I need to file an assignment recordal with the Canadian Intellectual Property Office? — Is the signed IP assignment agreement sufficient documentation or does CIPO require a specific form? — Does inventorship need to be formally amended or is ownership assignment separate from inventorship on the record? — Should I engage a patent agent for this or can it be done directly with CIPO?

Any guidance on the typical process or what to bring to a patent agent would be appreciated.

Removing a co-founder from an Ontario corporation and updating a patent filing after separation — Canada

Looking for general process guidance following a co-founder separation in Ontario. Not asking for legal advice, just trying to understand the typical steps and what questions to bring to a lawyer.

Background: I am the primary founder of a small Ontario corporation. My co-founder voluntarily stepped down in early 2026. We have a mutual release and share transfer agreement that she is expected to sign shortly, which assigns all her shares and IP to me and releases all claims. The RBC account associated with the corporation has a zero balance.

Corporate question: The share transfer agreement does not include a director resignation. Once she signs the share transfer, what additional steps are required to formally remove her as a director from the Ontario corporate registry? Is a Notice of Change sufficient or is there a formal director removal process required? Can I file the Notice of Change myself online through the Ontario Business Registry or does it require a lawyer?

What I am trying to accomplish: Full corporate control in my name, her name removed from all public Ontario corporate records, and updated banking with no shared signatory exposure.

Any guidance on typical process steps or what type of professional to engage first would be appreciated.
