The High Court has dismissed Alphapharm’s appeal from the Full Federal Court’s ruling granting Lundbeck an extension of time to apply to extend the term of the escitalopram patent. It was close though: 3 to 2.
You will recall that Lundbeck applied 10 years late to extend the term of its pharmaceutical patent. So, not only was Lundbeck applying to extend the term of its patent (under s70), it was applying for an extension of time in which to make that application. In granting special leave, the High Court accepted that, if the power were available, the circumstances justified the 10 year extension. The question was a matter of statutory interpretation: was there power to extend.
Section 71(2) specifies when an application to extend the term of a pharmaceutical patent must be made:
(2) An application for an extension of the term of a standard patent must be made during the term of the patent and within 6 months after the latest of the following dates:
(a) the date the patent was granted;
(b) the date of commencement of the first inclusion in the Australian Register of Therapeutic Goods of goods that contain, or consist of, any of the pharmaceutical substances referred to in subsection 70(3);
(c) the date of commencement of this section.
Lundbeck’s application was made within the term of the standard patent (with 1 day to spare), but well outside the dates specified in paragraphs (a) – (c).
Section 223 confers a general power to extend the time for making an application. Under s 223(11), however, the power cannot be used to extend time in relation to “prescribed actions”. One of those prescribed actions related to s 71(2):
(b) filing, during the term of a standard patent under subsection 71(2) of the Act, an application under subsection 70(1) of the Act for an extension of the term of the patent; ….
Crennan, Bell and Gageler JJ, after noting the long history in patents legislation of the power to apply for an extension of time, even after the time had expired, as an important safety valve in the system, ruled that s 71(2) specified 2 requirements. The first time requirement is that the application must be filed within the term of the standard patent. The second time requirement was that the application must also satisfy at least one of the requirements set out in paragraphs (a) – (c).
Crennan, Bell and Gageler JJ held, however, that reg. 22.11 applied only to the first requirement: that the application was made within the term of the standard patent. Their Honours considered this was important otherwise a “gap” could arise between when a patent expired but was then restored. That would be highly undesirable. In contrast, there was no policy reason why reg. 22.11 should apply to the second time requirement. At :
There is nothing in any of the extrinsic materials, or in the long policy debates on simplifying extensions of term, which would suggest any rationale for excluding the second time requirement from the remedial power to extend time under s 223(2)(a). Alphapharm’s senior counsel conceded, correctly, that if Alphapharm’s construction of reg 22.11(4)(b) were correct, the remedial power in s 223(2)(a) could never apply to extend time in relation to the second time requirement, no matter what the quality or provenance of any “error or omission” made in respect of that time. Alphapharm’s construction would introduce an inexplicable asymmetry between a patentee and a competitor opposing a s 70(1) application. An opponent can access the general remedial power to extend times cast upon it in mandatory terms. Had it been the legislature’s intention to exclude the second time requirement in s 71(2) from the general remedial power in s 223(2)(a), that would have been simple to accomplish.
Accordingly, s 223 could be invoked as Lundbeck had satisfied the first time requirement (and so did not need it to be extended) but needed an extension in relation to the second time requirement – which reg.22.11 did not apply to.
In dissent, Kiefel and Keane JJ rather tersely said at :
s 71(2) cannot reasonably be read as referring to two actions. There is but one action referred to in s 71(2) – making an application for extension of the term of a patent. That one action is to be done on a date that satisfies the two requirements as to time set out in s 71(2). It is that action to which s 223(2) would apply, were it not for reg 22.11(4)(b).
Their Honours did explain why they considered policy and historical considerations did not lead to a different conclusion. Of potentially more general interest, however, their Honours took a different stand on the role of statutory interpretation at :
In any event, as was said in Federal Commissioner of Taxation v Consolidated Media Holdings Ltd, legislative history and extrinsic materials cannot displace the meaning of statutory text; nor is their examination an end in itself. (footnote omitted)
A big bill coming? After the standard term of the patent expired but before the expiry of the extended term, Alphapharm and other generics commenced marketing their own versions of the drug.
