43.2       Dates

The international search report shall be dated and shall indicate the date on which the international search was actually completed.

(a)  The international search report shall contain the classification of the subject matter at least according to the International Patent Classification.

(b)  Such classification shall be effected by the International Searching Authority.

43.4       Language

Every international search report and any declaration made under Article 17(2)(a) shall be in the language in which the international application to which it relates is to be published, provided that:

(i)  if a translation of the international application into another language was transmitted under Rule 23.1(b) and the International Searching Authority so wishes, the international search report and any declaration made under Article 17(2)(a) may be in the language of that translation;

(ii)  if the international application is to be published in the language of a translation furnished under Rule 12.4 which is not accepted by the International Searching Authority and that Authority so wishes, the international search report and any declaration made under Article 17(2)(a) may be in a language which is both a language accepted by that Authority and a language of publication referred to in Rule 48.3(a).

For the purposes of this paragraph, Article 2(ii) shall not apply.
