“78. The rationale of the grounds for refusal of registration laid down in Art. 3(1)(e) of the Directive is to prevent trade mark protection from granting its proprietor a monopoly on technical solutions or functional characteristics of a product which a user is likely to seek in the products of competitors. Art. 3(1)(e) is thus intended to prevent the protection conferred by the trade mark right from being extended, beyond signs which serve to distinguish a product or service from those offered by competitors, so as to form an obstacle preventing competitors from freely offering for sale products incorporating such technical solutions or functional characteristics in competition with the proprietor of the trade mark. 79. As regards, in particular, signs consisting exclusively of the shape of the product necessary to obtain a technical result, listed in Art. 3(1)(e), second indent, of the Directive, that provision is intended to preclude the registration of shapes whose essential characteristics perform a technical function, with the result that the exclusivity inherent in the trade mark right would limit the possibility of competitors supplying a product incorporating such a function or at least limit their freedom of choice in regard to the technical solution they wish to adopt in order to incorporate such a function in their product. 80. As Art. 3(1)(e) of the Directive pursues an aim which is in the public interest, namely that a shape whose essential characteristics perform a technical function and were chosen to fulfil that function may be freely used by all, that provision prevents such signs and indications from being reserved to one undertaking alone because they have been registered as trade marks (see, to that effect, Windsurfing Chiemsee, paragraph 25).”
“Mr Turner’s evidence, by contrast, was to the effect that, in order to achieve a smooth shave, it was necessary to have an optimum faceplate area (a matter of engineering judgment) so as to achieve a smooth journey across the face and he regarded the lower residual areas of the triangular faceplate, as well as the clover leaf, as also playing an important part in this. On this difference, I preferred Mr Turner’s evidence, which appeared to me to make engineering sense and which he supported by analogies with the operations of smoothing irons and examples of particular uses of trays and paint tins on carpets. It is based on the proposition that the application of force to the movement of a small surface area across a deformable surface (such as skin) will be likely to meet greater resistance than the application of like force to a larger surface area. Mr Turner’s view also appeared to me to receive corroborative support from the unsuccessful and unsmooth operation of the 1993 model 68351, a model in which (in effect) the lower residual areas had been removed. In this context I make clear that I accept that there are different ways in which a clover leaf model can be designed, that a design in the traditional shape of the 452 mark, with a lower residual area, is not the only alternative, and that a design such as (for example) the Remington 9300 provides a successful alternative design (that has a clover leaf, no lower residual area, but does have a markedly gentle slope downwards from what I might call each inner point of the clover leaf). But I nevertheless accept Mr Turner’s general point that the lower residual areas in the 452 shape do contribute to achieving a smooth shaving operation. The comparison with the 9300 merely shows that there is more than one way to design an efficient and comfortable rotary shaver.”
“I also prefer Mr Turner’s evidence that the overall surface area of the faceplate (comprising both clover leaf and lower residual areas), all of which comes into contact with the skin, contributes to the smooth passage of the shaver across the face. I find therefore that the whole of the faceplate, including the clover leaf, contributes to the overall technical objective of giving the user a smooth, effective and comfortable shave and that therefore the whole of it is attributable to obtaining that technical result.”
“I accept Mr Schiferli’s evidence that the relevant function is performed by the flat surface of the faceplate and I accept also that the key element of skin-stretching and hair-raising is performed by that area described by Mr Schiferli surrounding each cutting head.”
“Q. And the one thing that you must have is smoothness? A. Smoothness and nicely rounded off corners when you move something on your face.”
