On July 11, 2007, the CFI retained for the first time the aesthetic complementary aspects of products to avoid having to deal with the diversification criterion (the Community case law does not want to hear about this criterion contrary to the French practice). The aesthetic complementary of products depends on how important one product is for the use of the other, how naturally consumers consider that they should be used together and the consumer’s perception of the products as items sold under the same mark.
