Art. 8 CDR : Designs dictated by their technical function and designs of interconnections
2. A Community design shall not subsist in features of appearance of a product which must necessarily be reproduced in their exact form and dimensions in order to permit the product in which the design is incorporated or to which it is applied to be mechanically connected to or placed in, around or against another product so that either product may perform its function.
3. Notwithstanding paragraph 2, a Community design shall under the conditions set out in Articles 5 and 6 subsist in a design serving the purpose of allowing the multiple assembly or connection of mutually interchangeable products within a modular system.

1. Article 8(1) of Council Regulation (EC) No 6/2002 of 12 December 2001 on Community designs must be interpreted as meaning that in order to determine whether the features of appearance of a product are exclusively dictated by its technical function, it must be established that the technical function is the only factor which determined those features, the existence of alternative designs not being decisive in that regard.
2. Article 8(1) of Regulation No 6/2002 must be interpreted as meaning that, in order to determine whether the relevant features of appearance of a product are solely dictated by its technical function, within the meaning of that provision, the national court must take account of all the objective circumstances relevant to each individual case. In that regard, there is no need to base those findings on the perception of an ‘objective observer’.
