CPC - A61K - 2013.07 - page 5
NOTE
-
Use of cosmetics or similar toilet preparations is further classified in subclass A61Q
.
1. Use of cosmetics or similar toilet preparations is mandatorily further classified in
subclass A61Q . 2. In each of groups A61K 8/02 and A61K 8/18 , in the absence of
an indication of the contrary, classification is made in the last appropriate place. 3.
Attention is drawn to the Notes in class C07 , for example the notes following the
title of subclass C07D , setting forth the rules for classifying organic compounds in
that class, which rules are also applicable, if not otherwise indicated, to the
classification of organic compounds in group A61K 8/00 . 4. Salts or complexes of
organic compounds are classified according to the base compounds. If a complex is
formed between two or more compounds, classification is made for each
compound.
