Under Section 20 of the Canadian Patent Act, the government can place a secrecy order on inventions vital to national defence. Your patent application will be classified, hidden from the public, and you may receive financial compensation from the Crown for the use of your technology.
Innovation in the defence and military sectors is critical for national security. 📍 If you or your company invent a new weapons system, advanced radar technology, or secure military communications equipment in Canada, your intellectual property application may not follow the standard public route. The Canadian government holds the legal authority to classify specific inventions to ensure sensitive technology does not fall into the hands of foreign adversaries or the general public.
Dealing with classified intellectual property requires extreme caution and specialized legal knowledge. If you believe your invention has military applications, we strongly advise using our directory to consult a registered Canadian patent agent who has security clearance. Violating a secrecy order is a severe offence, and navigating Section 20 of the Patent Act requires professional guidance to ensure you are legally protected and fairly compensated.
Step-by-Step Process for Military Patents Under Section 20
Secrecy orders are handled strictly at the federal level between the Canadian Intellectual Property Office (CIPO) and the Department of National Defence (DND), whether you are based in the defence hubs of Ottawa or Halifax. 📝 Here is how the process generally unfolds for sensitive military inventions.
Step 1: Filing the Patent Application with CIPO
The process begins exactly like any standard invention. You and your patent agent draft the technical claims and file the application with CIPO. At this stage, the application is kept confidential, as all Canadian patent applications are automatically hidden from the public for the first 18 months after filing.
Step 2: Review by the Minister of National Defence
CIPO screens all incoming patent applications. 👮♂️ If an examiner determines that the invention pertains to instruments or munitions of war, or otherwise impacts national security, CIPO is legally required to refer the application to the Minister of National Defence (MND). The MND and military technical experts will then review the invention to assess its strategic value to Canada.
Step 3: Imposition of the Secrecy Order
If the MND decides the invention must be protected, a formal Secrecy Order is issued under Section 20 of the Patent Act. Once this order is in place, your application is completely removed from the standard CIPO processing queue. It will not be published after 18 months, you cannot discuss the invention publicly, and you are strictly prohibited from filing patent applications for the same invention in foreign countries without explicit government permission.
Step 4: Government Use and Compensation Negotiation
When an invention is placed under a secrecy order, the Crown does not require you to surrender your ownership without reason. You can request compensation for the loss of commercial exploitation. The government will negotiate a settlement with you, or you can have the Federal Court of Canada determine a fair amount. It is critical to ensure your patent lawyer has the appropriate clearances to handle these high-level negotiations.
How Much Does it Cost in Canada?
While the standard government fees for filing a patent remain the same, handling a Section 20 secrecy order involves significant specialized legal work. Here are the typical costs and financial factors to consider.
- CIPO Standard Filing Fee: Exactly $595.06 CAD (or $241.24 CAD for a small entity) as of 2026.
- Security Cleared Patent Agent Fees: Usually range from $10,000 to $25,000+ CAD, as these professionals must have proper clearance and expertise to negotiate with the DND.
- Government Compensation: Variable. Instead of costing you money, a secrecy order often results in the Crown paying you royalties or a lump sum for the right to use your military technology.
- Federal Court Litigation: If compensation negotiations fail, taking the matter to the Federal Court can cost upwards of $50,000 CAD in legal fees.
How Long Does the Process Take?
The timeline for a patent under a secrecy order is entirely dependent on national security needs. ⌛ The secrecy order can last for years, or even decades, as long as the technology remains relevant to national defence. Your patent application will effectively remain frozen in a classified state. Once the technology becomes obsolete or public knowledge, the MND may lift the secrecy order, allowing the patent to proceed through the normal CIPO examination process.
Frequently Asked Questions (FAQ)
Can I sell my military invention if it is under a secrecy order?
No. Once a secrecy order is issued, you cannot commercialize, sell, or publicly disclose the invention to any private companies or foreign entities. The Canadian government has exclusive rights to use or suppress the technology for national security reasons.
Can I apply for a patent in the United States?
Not without permission. Section 20 strictly prohibits you from filing a foreign patent application for a classified invention unless you receive written consent from the Canadian Minister of National Defence. Doing so illegally is a severe offence.
What happens if I violate the secrecy order?
Violating a Section 20 secrecy order is a major breach of national security. You could face criminal prosecution under the Security of Information Act, resulting in severe financial penalties and potential imprisonment.
Who decides if the compensation offered by the government is fair?
Your legal team will attempt to negotiate a fair royalty or buyout with the DND. If both parties cannot agree on what constitutes fair compensation, the Commissioner of Patents or the Federal Court of Canada will intervene to determine the final amount.
Will my patent ever become public?
It is possible. If the Minister of National Defence eventually determines that the invention no longer poses a security risk, they will waive the secrecy order. At that point, the application returns to CIPO, resumes normal examination, and may be published.
