Forecast 2022: Expected Changes to the Canadian Patent Rules

Following a major overhaul in late 2019, further changes to the Canadian Patent Rules are expected this year. The proposed changes are intended, in part, to help Canada meet its obligations under the Canada-United States-Mexico Agreement (CUSMA) by streamlining its patent prosecution procedure. Below is a high-level summary of the substantive proposed changes:

Excess Claim Fees

Canada is expected to impose “excess claim fees”. The table below compares the current rules to the proposed rules:

	Current rules	Proposed rules
Number of claims permitted before excess claim fees are levied	Unlimited[1]	20
Expected cost per excess claim	n/a	CA$100[2]

Under the proposed changes, “excess claim fees” are expected to be evaluated at two points during prosecution: (i) at the time that a request for examination is filed; and (ii) at the time that the final fee (i.e., the fee required for issuance of a patent) is due. At the time that the final fee is due, an applicant must pay an excess claim fee for each claim in excess of 20 that had not already been paid for at the time that examination was requested.

Request for continued examination

Canada is expected to adopt a request for continued examination (RCE) procedure. The proposed RCE procedure is also expected to replace the current mechanism for withdrawing an application from allowance and returning it to examination[3]. The table below compares the current rules to the proposed rules:

	Current rules	Proposed rules
Number of office actions after requesting examination	Unlimited, and at the discretion of the patent examiner	up to 3
Cost for RCE	n/a	CA$816[4]
Additional office actions after each RCE	n/a	up to 2
Option for additional RCE?	n/a	Yes

Conclusion

While Canada remains a patent-friendly jurisdiction at least in view of its deferred examination process and permissiveness of multiple claim dependencies, patent applicants should nevertheless consider how the above incoming changes may affect their patent strategies. The proposed excess claim fees are expected to be effective for applications for which examination is requested more than 30 days after these changes to the Patent Rules come into force. As a result, significant excess claim fees can be avoided by requesting examination before the passing of 30 days after the effective date of these changes. Where applicants have more than 20 claims in applications for which examination has not yet been requested, we strongly encourage considering requesting examination before this period has lapsed.

The proposed changes are expected to come into force in early 2022, and a further bulletin will follow at that time.
