JUDGMENT AND REASONS
I. Overview
[1] A company that holds a drug patent can protect the patent from infringement by other companies under rules set out in patented medicine regulations: Patented Medicines (Notice of Compliance) Regulations, SOR/93-133 [Regulations] (provisions cited are set out in the Annex). That protection begins when the Minister of Health lists the patent on the patent register. The listing date is critical.
[2] The applicants [collectively, Serono] are drug companies who argue that the Minister unreasonably delayed listing their patent on the register, resulting in a loss of their patent rights. The Minister’s approach to listing patents, says Serono, fails to respect statutory, regulatory, and treaty obligations, as well as the Minister’s own policies. Serono asks me to quash the Minister’s decision and declare the patent listed as of the earlier date on which the Minister should have added it to the register. The intervener Innovative Medicines Canada [IMC] supports Serono’s position.
[3] The respondents – the Minister of Health and Apotex, supported by the intervener the Canadian Generic Pharmaceutical Association [CGPA] – argue that the Minister’s approach was reasonable and legally sound. The respondents ask me to dismiss Serono’s application for judicial review of the Minister’s decision.
[4] The sole issue is whether the Minister’s decision was unreasonable.
[5] I find that the Minister’s decision on the listing date for Serono’s patent was not unreasonable in light of the governing Regulations and case law. The Minister adds patents to the register when they are eligible for listing – not sooner, not later. Accordingly, I must dismiss Serono’s application for judicial review.
II. Background
A. The Legal Framework
[6] The Regulations refer to drug patent holders as “first persons”
and generic drug companies as “second persons.”
[7] The Regulations impose on the Minister an obligation to maintain a register of patents for approved drugs. Before listing a patent, the Minister must decide whether the patent meets the requirements of the Regulations, namely, whether the patent relates to an approved medicine, contains a claim for an approved formulation of that medicine, identifies a claim for an approved dosage form, or specifies an approved use of the medicine (s 4(2)).
[8] Once the Minister has added a patent to the register, the Regulations prohibit second persons from entering the market for the same medicine, except in accordance with strict conditions (s 7(1)). In addition, a second person who seeks to market a generic version of the patented drug must first address any patents already listed on the register (ss 5(1) and 5(4)). This regulatory arrangement is often referred to as the “frozen register”
because it freezes in time the patents that a second person must address. The second person can address the listed patents by accepting that it will not enter the market until the patents expire, by obtaining the first person’s consent, or by alleging that the patent is invalid or would not be infringed by the second person’s product (s 5(2.1)).
[9] Where the second person asserts that the listed patent is invalid or would not be infringed, it must serve a Notice of Allegation [NOA] on the first person (s 5(3)). The first person can then bring an action for a declaration that the second person’s product would infringe the patent (s 6(1)). The action bars the Minister from allowing the second person to enter the market for 24 months (s 7(1)(d)).
B. Serono’s Patent
[10] Serono filed its application for Canadian Patent No 3,087,419 [the ‘419 patent] in December 2005. The patent is entitled “Cladribine Regimen for Treating Multiple Sclerosis.”
The Canadian Intellectual Property Office [CIPO] granted the ‘419 patent on March 7, 2023.
[11] On March 16, 2023, 9 days after the granting of the patent, Serono submitted patent lists for the ‘419 patent against a product called MAVENCLAD, a drug used in the treatment of adult patients with relapsing-remitting multiple sclerosis. Health Canada screened the patent lists the next day and then, on March 21, 2023, carried out a preliminary analysis of the patent’s eligibility for listing. On March 23, 2023, the Office of Submissions and Intellectual Property [OSIP] informed Serono by letter that its patent lists had been added to the register as of that date – March 23, 2023, one week after Serono submitted its patent lists for the ‘419 patent.
[12] One day earlier, on March 22, 2023, Apotex filed its regulatory submission for a generic version of MAVENCLAD. Because Serono’s patent lists had not yet been added to the register, it appeared that Apotex did not have to address the ‘419 patent.
[13] Nevertheless, on April 20, 2023, Serono asked OSIP to reconsider the listing date of March 23, 2023, arguing that the proper date should have been the date on which it had submitted its patent lists – March 16, 2023. Based on that date, Apotex would have had to address the ‘419 patent on March 22, 2023.
C. The Minister’s Decision
[14] In response to Serono’s request, OSIP informed Serono that the Minister maintained the listing date of March 23, 2023, the date of the eligibility decision.
[15] The Minister observed that the Regulations distinguish between submitting a patent list and adding a patent to the register. The Minister must maintain a register of patents that have been submitted for listing by adding those patents that meet the applicable eligibility requirements, and by refusing to add patents that do not meet those requirements (s 3(2)). As mentioned, a patent is eligible to be added to the register if it claims an approved medicinal ingredient, formulation, dosage form, or use (s 4(2)).
[16] The Minister also cited the distinction between submission of a patent list and the addition of patents to the register in s 5(1) of the Regulations. That provision requires second persons to address patent lists that have been submitted. However, the statements and allegations in the second person’s NOA must be directed at patents that are included on the register (s 5(2.1)). The Minister found that, when read together, these provisions reinforce the distinction between the submission of patent lists and the addition of patents to the register.
[17] The Minister rejected Serono’s argument that eligible patent lists should be added to the register on the date they are submitted and that second persons should have to address those patents as of the date of submission. The Minister pointed out that the Regulations provide that second persons do not have to address patents that were added to the register on or after the date the second person filed its submission for a notice of compliance (ss 5(1),(4)). Again, the regulatory provisions confirm the distinction between the submission of patent lists and the addition of patents to the register.
[18] In support of his analysis, the Minister cited the 2006 Regulatory Impact Assessment Statement, SOR/2006-242, October 5, 2006, PC 2006-1077 [2006 RIAS] at 1510. In his view, the RIAS confirms that the Regulations require second persons to address patents that are eligible for addition to the register, and that have actually been added to the register. The Minister also cited Health Canada’s Guidance Document for the Regulations, which reiterates that requirement, supporting the Minister’s conclusion that the correct date for adding a patent to the register is the date on which it was found to be eligible, not the date on which it was submitted (Guidance Document – Patented Medicines (Notice of Compliance) Regulations (Revised date 2021/04/08)).
[19] The Minister also found that the purpose of the Regulations is to “balance effective patent enforcement over new and innovative drugs with the timely entry of their lower priced generic competitors.”
In the Minister’s view, that balance would be upset if second persons had to address patents added to the register after they had already filed their submissions.
[20] Finally, the Minister found that his position was supported by case law: Eli Lilly Canada Inc v Canada (Attorney General), 2009 FC 474 [Eli Lilly]. There, Lilly had argued that the Minister had a discretion to list a patent on the register on the date the patent list was filed. Justice Robert Barnes rejected that argument and concluded that second persons must address patents that have been found to be eligible for listing and added to the register, not patents that have merely been filed.
III. Was the Minister’s Decision on the Listing Date Unreasonable?
A. The Submissions of Serono and IMC
[21] Serono describes the provisions of the Regulations as setting up a race between first persons and second persons. First persons rush to get their patents added to the register; second persons hurry to file their generic drug submissions. Serono says it won the race against Apotex. Serono filed its patent lists on March 16, 2023; Apotex filed its drug submission on March 22, 2023. Serono attributes the one-week delay in the addition of its patent to the register (on March 23, 2023) to the Minister.
[22] Serono contends that the Minister’s decision to add the patent to the register a week after it was submitted was unreasonable because the Regulations do not admit of any discretion to delay – the Minister must simply add eligible patents to the register (s 3(2)). Serono argues that any delay between submission of an eligible patent and its listing on the register risks depriving first persons of their patent rights, contrary to the intent of the Regulations. Serono maintains that the Minister failed to consider its argument that the Minister had arbitrarily delayed adding the ‘419 patent to the register, to Serono’s prejudice, and that the Minister did not offer any explanation for the delay between March 16 and March 23.
[23] Serono offers an alternative to the Minister’s interpretation of the Regulations, relying primarily on the wording of s 5(1). That subsection requires second persons to address patent lists that have been submitted by a first person. This language is consistent with the wording of s 3(2) of the Regulations, which requires the Minister to maintain a register of “patents that have been submitted for addition to the register.”
Serono contends that a second person must, therefore, address patents that were submitted by a first person before the second person filed its drug submission. The critical date, according to Serono, is the date on which the first person submits a patent for addition to the register, not the date on which it was actually added. Serono argues that any other interpretation of the Regulations would be unreasonable because it would fail to give meaning to the word “submitted.”
[24] Serono submits that the Eli Lilly case on which the Minister relied is distinguishable. There, the Minister had found Lilly’s patent ineligible for listing on the register. A year later, the patent was found to be eligible. Lilly asked the Minister to deem the patent to have been added to the register as of the date it was submitted, not the date on which it was found to be eligible. The Minister refused and Justice Barnes found that the Minister’s decision was correct. Serono says that its argument differs from Lilly’s: Serono does not contend that its patent should have been added to the register before it was found to be eligible – rather, it argues that the Minister had a duty to review and determine the patent’s eligibility immediately, not a week after it was submitted.
[25] Serono compares itself to the applicant in Abbott Laboratories Limited v Canada (Attorney General), 2007 FC 797 [Abbott]. There, the patent was added to the register 5 days after issuance. After amendments to the Regulations, the Minister delisted the patent on the grounds that it was no longer eligible. On judicial review, the Court found that the patent should not have been delisted and ordered that it be relisted retroactively, to the date on which the Minister had delisted it. Serono argues that its patent should be added to the register as of the date on which it should have been added, namely, the date it was submitted. In the alternative, Serono proposes that its patent should have been added to the register on March 21, 2023, the date on which staff completed the screening and eligibility review form. There is no justification, says Serono, for the two-day delay between that review and the eligibility decision.
[26] In addition, says Serono, listing delays violate Canada’s obligations under the Canada-United States-Mexico Agreement, 30 November 2018, Can TS 2020 No 5 (entered into force 1 July 2020) [CUSMA], which requires Canada to provide a fair system for balancing and litigating the interests of first and second persons. Similarly, the Minister’s own Standard Operating Procedure for Administration of the Patented Medicines (Notice of Compliance) Regulations states that the Minister must examine patents “immediately,”
if possible.
[27] IMC concurs with Serono that the patent should have been added to the register on the date on which it was found by staff to be eligible – March 21, 2023. The Minister’s two-day delay in communicating the eligibility decision, in effect, unreasonably penalized Serono.
[28] IMC also submits that a second person should be required to address any patent that was submitted for addition to the register before the second person filed its drug submission. This requirement, says IMC, better reflects the purpose of the Regulations, which is to ensure that eligible patents are protected from infringement by second persons. The Regulations recognize the strong public interest in encouraging drug innovation and the high commercial value of patents by granting first persons a right of action to protect their patent rights against second persons and a 24-month stay against second persons entering the market. Accordingly, IMC maintains that the Minister must interpret the Regulations reasonably and with a view to respecting those significant interests.
[29] In addition, IMC argues that requiring a second person to address a patent submitted before, but added to the register after, the second person filed its drug submission would not cause any prejudice – second persons can always change or update their submissions to address those patents.
B. The Minister’s Decision was not Unreasonable
[30] I do not agree with Serono’s and IMC’s characterization of the Minister’s decision. The decision was not unreasonable in the context of the Regulations, the case law, and the facts.
[31] I agree with Serono’s and IMC’s description of the basic purposes of the Regulations and the balance they seek to achieve between first and second persons. However, I disagree that these factors point to an interpretation of the Regulations that would require the Minister to add patents to the register immediately upon submission, or after a preliminary review by staff, or that would require second persons to address patents that have not yet been added to the register. The Minister does not have a discretion to delay adding patents to the register, but the Minister does exercise discretion in determining whether patents are eligible for listing.
[32] To interpret the Regulations in the manner urged by Serono and IMC, one would have to read certain provisions in isolation; that is not a reasonable approach to interpreting the Regulations. For example, the opening words of subsection 3(2) say that the Minister must “maintain a register of patents that have been submitted for addition to the register...”
On its own, this passage seems to require the Minister to maintain a register of submitted patents. If that were so, second persons would have to address patents submitted by first persons, not just those actually added to the register. Indeed, this interpretation is reinforced if one reads another provision in isolation, subsection 5(1). It states, in effect, that a second person must address patents that have been submitted by a first person. If the Regulations said no more, one might reasonably conclude that patents are added to the register when submitted, and that second persons must address those patents. But the Regulations do say more.
[33] According to the Regulations, read as a whole, the patent register contains those patents the Minister has determined to be eligible for addition. Patents are not added to the register immediately upon submission. In particular, reading the opening words of subsection 3(2) along with the ensuing paragraphs ((a) and (b)), the Regulations require the Minister to “maintain a register of patents that have been submitted for addition to the register”
by adding them to the register if they meet the eligibility requirements, and by refusing to add them if they are ineligible.
[34] Similarly, reading subsection 5(1) along with the ensuing subsections, second persons must address patents that have been submitted by a first person by setting out statements and allegations in its NOA with respect to each relevant patent included on the register (s 5(2.1)). Second persons need not address patents that get added to the register later (s 5(4)(a)).
[35] To read the Regulations in the limited way Serono and IMC urge me to do would be unreasonable because it would overlook the language in these other provisions that provide additional information and context for the provisions on which they rely.
[36] The Minister reasonably relied on the 2006 RIAS in support of this interpretation of the Regulations. According to the RIAS, the intention of the Regulations is to require second persons to address patents that have been found to be eligible and added to the register, not those that have merely been submitted:
Only those patents which meet the current timing, subject matter and relevance requirements set out in section 4 of the regulations are entitled to be added to Health Canada’s patent register and to the concurrent protection of the 24-month stay.
[…]
[A] generic manufacturer that files a submission . . . is only required to address the patents on the register in respect of the innovative drug as of that filing date. Patents added to the register thereafter will not give rise to any such requirement. The register will thus be “frozen” in respect of that generic manufacturer’s regulatory submission.
(2006 RIAS at pp 1511, 1519).
[37] Similarly, the Minister reasonably relied on the Guidance Document for the Regulations in support of his conclusion. The Guidance Document, in the passages below, makes clear that patents are added to the register only after they have been reviewed and found to be eligible, and that second persons need only address patents that have actually been added:
· The requirements that must be met before a patent can be added to the Patent Register are provided by section 4 of the PM(NOC) Regulations (4.1, p 11).
· The RMOD [Resource Management and Operations Directorate] will not add any patent... until it has completed a final evaluation and is satisfied that the patent... meets the eligibility requirements set out in section 4 (4.8, p 18).
· The RMOD is required to add any patent on a patent list... that meets the requirements for addition to the Patent Register and to refuse to add any patent... that does not meet the requirements for addition to the Patent Register (7, p 28).
[38] The Minister’s interpretation is also supported by the Eli Lilly case, which he cited. There, Lilly submitted its patent list in November 2006. Two months later, the Minister found Lilly’s patent to be ineligible for listing. The parties communicated back and forth over the ensuing months until, in November 2007, the Minister agreed to list the patent. Lilly then asked the Minister to backdate the listing to November 2006, when the patent list had originally been submitted. Lilly argued that the date of submission was the proper date for the addition of a patent to the register because the submission itself provided sufficient notice to second persons who may be considering filing a drug submission for a generic version of the patented medicine. The Minister refused that request, finding that the proper date for listing was the date on which the patent was found to be eligible – in November 2007. Lilly asked the Minister to reconsider. The Minister refused, noting that the Regulations require that patents be added to the register after they have been found to be eligible, not when they are submitted for listing (para 5).
[39] On judicial review of the Minister’s decision, Justice Barnes (there applying a standard of correctness, not unreasonableness) concluded that the Minister’s decision was correct. He characterized Lilly’s argument, essentially the same as Serono’s and IMC’s here, as “tenuous,”
“isolated,”
and “self-serving”
(para 11). Justice Barnes reviewed the very provisions that I have considered above and arrived at the same interpretation of them (para 15):
The obvious intent of these provisions is that the listing of a patent on the register is to be done contemporaneously with the Minister’s determination of the patent’s eligibility for listing. The effect of this is that, under ss. 5(4), a second person need not address any patent added to the register after the date of the second person’s submission for a NOC under ss. 5(1) or ss. 5(2).
[40] Justice Barnes observed that the burden of any passage of time between submission and listing falls on first persons. But that was a legislative choice. And the interpretation urged by Lilly would create its own problems by requiring second persons to address patents that are ineligible for listing.
[41] While Serono maintains that Eli Lilly can be distinguished from this case because it dealt with a situation where a patent was found first to be ineligible, and then eligible, I cannot see how that difference is relevant. Justice Barnes interpreted the same provisions of the Regulations that are in issue here and, subject to strong reasons to believe he erred, I am bound by his interpretation. I see no error in his judgment.
[42] I find that the cases on which Serono relies are distinguishable.
[43] In the Abbott case, the Minister had originally listed Abbott’s patent in July 2006 but, after amendments to the Regulations in October 2006, the Minister found the patent no longer eligible for listing. He delisted it in February 2007. Justice Sandra Simpson found that the amendments specifically granted the Minister the power to delete from the register patents that were no longer eligible. However, she went on to find that the patent was not, in fact, ineligible for listing. She ordered that the patent be added to the register as of the date on which the Minister had delisted it. She did not, I note, order that the patent be added to the register as of the date it was originally submitted, or even as of the date it was originally listed. Abbott does not assist in interpreting the provisions of the Regulations in issue here; nor does it advance Serono’s position.
[44] Serono also cites Èquiterre v Canada (Health), 2016 FC 554 [Èquiterre]. There, the Minister had a statutory obligation to begin a special review of any pest control products that were banned by an OECD country (Pest Control Products Act, SC 2002, c 28, s 17(2)). The applicants asked the Minister to begin a number of special reviews of products prohibited in OECD countries; after several months, the Minister refused to initiate a review of some of them. Justice Michael Phelan held that the Minister’s delay was unreasonable because the obligation to initiate a special review arose immediately upon becoming aware of an OECD ban (para 58).
[45] Serono maintains that the same obligation arises here – the Minister must immediately review patents submitted by first persons and must add them to the register immediately upon determining them to be eligible. I note, however, that while Justice Phelan stated that the Minister’s obligation arose “immediately”
upon becoming aware of an OECD ban, he went on to say that this obligation required the Minister to commence special reviews within a “reasonable time,”
and declined to define what a “reasonable time”
was (para 59). Accordingly, Équiterre does not support Serono’s submission that the Minister must act “immediately.”
Further, the evidence here shows that Health Canada screened Serono’s patent the day after it was submitted. Four days later, on March 21, 2023, staff completed the screening and eligibility review form. However, the day on which staff completed the screening and eligibility form is not the day of the Minister’s own determination of the patent’s eligibility to be listed. The Minister added the patent to the register on the same day that it was determined to be eligible, on March 23, 2023. There was no delay.
[46] In sum, the Minister’s interpretation of the Regulations was not unreasonable. The Regulations permit a first person to submit a patent for addition to the register. The Minister must add to the register those patents that meet the regulatory requirements, and must refuse to add patents that do not meet those requirements (ss 3(2)(a),(b)). Accordingly, once a patent has been submitted for addition to the register, the Minister must determine whether the regulatory requirements have been met (s 4(2)). The addition of a patent to the register is not automatic; it must await a determination of whether the patent is eligible. Determining eligibility requires a review of the patent to see whether it claims an approved medicinal ingredient, formulation, dosage form, or use.
[47] A second person must address those patents that have been submitted by a first person, reviewed by the Minister and added to the register (ss 5(1),(2.1)). A second person does not have to address a patent that was submitted by a first person for addition to the register but not yet added to the register. Nor does a second person need to address a patent added to the register on or after the date of the second person’s drug submission (s 5(4)(a)).
[48] Accordingly, the Minister’s decision that Serono’s patent was properly added to the register on the date it was found to be eligible – March 23, 2023 – was not unreasonable. When Apotex filed its drug submission on March 22, 2023, Serono’s patent had not yet been added to the register; Apotex had no obligation to address it.
IV. Conclusion and Disposition
[49] The Minister’s decision to list Serono’s patent on the date on which the Minister determined it to be eligible for listing was not unreasonable given the facts and the regulatory context. Therefore, I must dismiss this application for judicial review.
[50] The parties agree that costs should be determined in accordance with the middle of Column III of Tariff B in the Federal Courts Rules, SOR/98-106, with no costs to be awarded in favour of or against the interveners. Should the parties wish to make submissions to the Court on costs, they may do so within 10 days of the issuance of this decision.
