Co-branding activities involve the joint use of brands by companies that intend to pursue common objectives. They should be governed by contracts to formalise the economic, practical, legal aspects of the operation, including intellectual property: brand licensing, product liability, duration of the agreement. From a commercial point of view, the benefits of co-branding have been widely analysed.  The legal advantages, with particular reference to the possibility of increasing the distinctive force of the mark, to widen its sphere of protection and to limit its forfeiture for non-use, are explored in the article: The legal advantages of co-branding, published by NT Plus Diritto del Sole24ore.
