182 The <strong>WIPO</strong> <strong>Journal</strong><br />
PLT r.2(5) provides two different types of requirements 48 : obligatory requirements (indicated by “shall”),<br />
and optional requirements (indicated by “may require”). Each PLT contracting party can decide which<br />
optional requirements it incorporates into its law as compulsory requirements for the accordance of a<br />
filing date. PLT art.5(7)(b) permits a contracting party to regard an application as not having been filed<br />
if the applicant fails to comply with the obligatory and any optional requirements under PLT r.2(5)<br />
implemented as compulsory by a PLT contracting party. 49<br />
PLT r.2(5)(a) prescribes that the indication that the description and any drawings are replaced by the<br />
reference to the previously filed application, as well as the number of that application and the office with<br />
which that application was filed, must be included in the application. According to PLT r.2(5)(a), a PLT<br />
contracting party may require that the reference also indicates the filing date of the previously filed<br />
application. PLT r.2(5)(a) does not require that the reference identifies any claims of the previously filed<br />
application that are incorporated by reference, since claims are not required for the purposes of the filing<br />
date. 50 In addition, a PLT contracting party may decide which of the optional requirements mentioned in<br />
PLT r.2(5)(b) are made compulsory for the accordance of a filing date:<br />
• filing a copy of the previously filed application and, where the previously filed application<br />
is not in a language accepted by the office, a translation of that previously filed application,<br />
be filed with the office within a time-limit which shall be not less than two months from the<br />
date of receipt of the application;<br />
• filing a certified copy of the previously filed application with the office within a time-limit<br />
which shall be not less than four months from the date of the receipt of the application.<br />
Where the applicant indicated in the application containing the reference is not the same as the applicant<br />
identified in the previously filed application, the office pursuant to PLT r.2(5)(c) may require a declaration<br />
or other evidence that the previously filed application had been filed by that applicant’s predecessor or<br />
successor in title. 51 The latter requirement is not often implemented in the patent law of PLT contracting<br />
parties. 52<br />
Filing by reference to a previously filed application—PCT<br />
With respect to “filing by reference” the PCT was not aligned to the PLT. There was an initial proposal<br />
to incorporate a new r.20.4(e) into the PCT, which would provide for a reference to another document to<br />
replace the description, drawings and claims. 53 The formulation included 54 :<br />
“For the purposes of Article 11(1)(iii)(d), a reference, made upon filing of the international application,<br />
in a language accepted by the receiving Office under Rule 12.1(a), to a previously filed application<br />
shall … replace the description and any drawings and, if applicable, the claim or claims.”<br />

The EPO has not implemented this requirement in r.56 EPC 2000. In the UK, the Patent Act 1997 (as amended) includes a provision in art.15(1)(c)(ii)<br />
stating that a reference to an earlier relevant application must be “made by the applicant or a predecessor in title of his”.<br />
