It is desirable to promote throughout the Community a
harmonious development of economic activities and a
continuous and balanced expansion by completing an
internal market which functions properly and offers
conditions which are similar to those obtaining in a
national market. In order to create a market of this kind and
make it increasingly a single market, not only must barriers
to free movement of goods and services be removed and
arrangements be instituted which ensure that competition
is not distorted, but, in addition, legal conditions must be
created which enable undertakings to adapt their activities
to the scale of the Community, whether in manufacturing
and distributing goods or in providing services. For those
purposes, trade marks enabling the products and services of
undertakings to be distinguished by identical means
throughout the entire Community, regardless of frontiers,
should feature amongst the legal instruments which
undertakings have at their disposal.
