Pursuant to the decision n. 4386 issued on March, 4 2015 by the Italian Court of Cassation "the investigation about similarity of products consists in assessing if the goods or services at stake are looked for and bought by the public by virtue of identical or at least strictly linked motivations, so that the existing functional similarity between those products and services and between the related market fields induces the consumer to naturally believe that they come from the same productive source, independently from the mere extrinsic fact of the possible identity of marketing channels".
