Accelerated Patent Review in Canada: The Patent Prosecution Highway (PPH)

Securing a patent in Canada is a monumental step for any technology company or inventor. However, standard patent examinations can drag on for years, leaving your innovations vulnerable while you wait for approval. Fortunately, Canada participates in a global initiative known as the Patent Prosecution Highway (PPH). If you have already successfully patented your invention in another participating country, you do not have to start from scratch in Canada. Whether you are a biotech startup in Vancouver, an AI firm in Toronto, or an engineering hub in Calgary, the PPH program provides a highly efficient shortcut.

By leveraging the work already done by foreign patent examiners, CIPO can process your Canadian application with incredible speed. 💼 However, utilizing the PPH requires strict adherence to technical matching rules. The claims in your Canadian application must perfectly align with those approved abroad. Because navigating these complex requirements is highly technical, it is generally highly recommended to hire a registered Canadian patent agent or an intellectual property law firm to manage the submission.

Step-by-Step Process in Canada

Filing a PPH request requires precision. If your Canadian claims deviate too far from the foreign approved claims, CIPO will reject the accelerated review request and dump your file back into the standard, multi-year waiting line.

Step 1: Secure a Favourable Foreign Office Action

Before you can apply for the PPH in Canada, you must have an allowable claim from a recognized foreign patent office. Canada has PPH agreements with major global players, including the United States, Europe, Japan, and China. Once the foreign examiner issues a formal notice of allowance or a positive examination report indicating that at least one of your claims is patentable, you can trigger the Canadian process.

Step 2: Ensure Claim Correspondence

This is the most critical step. Your Canadian patent agent must review your pending Canadian application and amend the claims so that they sufficiently correspond to the approved foreign claims. 📋 You cannot try to sneak in broader protections in Canada than what was granted abroad. The claims must have the exact same scope, or be narrower. If they do not match, the PPH request will fail.

Step 3: Submit the PPH Request to CIPO

Once the claims are matched, your law firm will submit a formal PPH request form to CIPO. This submission must include copies of all the foreign office actions, the allowed foreign claims, and translated versions if the original documents were not in English or French. You must also include a claims correspondence table that clearly shows the CIPO examiner how each Canadian claim maps directly to the approved foreign claim.

Step 4: Examination Under PPH Status

If your PPH request is approved, CIPO places your application at the front of the queue. 🔬 The Canadian examiner will review the file. While they heavily rely on the foreign examiner’s work, CIPO still conducts an independent review to ensure the invention complies specifically with the Canadian Patent Act. It is very common to still receive minor office actions in Canada that your agent must address.

Step 5: Payment of the Final Grant Fee

Once the CIPO examiner is satisfied, they will issue a Notice of Allowance. Your patent agent will then pay the final Canadian final fee. Upon payment, CIPO will formally grant your Canadian patent, securing your intellectual property rights across the entire country.

How Much Does it Cost in Canada?

Using the PPH is financially advantageous because it dramatically reduces the amount of back-and-forth arguments (office actions) you have to pay your lawyer to draft.

• CIPO PPH Request Fee: Filing the actual PPH request form is currently free of government charges.
• Standard CIPO Examination Fee: You must still pay the standard examination request fee, which is approximately $1,190.13 CAD (or $482.48 CAD for small entities).
• Patent Agent Fees: Drafting the claims correspondence table and submitting the PPH request through a registered Canadian patent agent typically costs between $1,500 and $3,500 CAD.
• Translation Costs: If your foreign patent is not in English or French, certified translations generally cost $30 to $50 CAD per page.

How Long Does the Process Take?

The time savings provided by the PPH are massive. A standard patent application at CIPO typically takes 3 to 5 years to be fully examined and granted. By utilizing the Patent Prosecution Highway, you skip the massive backlog. Once the PPH request is accepted, CIPO’s standard service target to issue its first office action or notice of allowance is up to 7 months (which is achieved in 90% of cases). The entire process, from PPH submission to the final granted patent, is often completed in under 12 months.
