As anyone who is in the business of selling a product knows it is important to do whatever one can to set their product apart. Finding ways to legally protect a design or recipe are common. Some businesses even trademark colors used in their packaging. Chocolate maker Cadbury successfully did this with its purple wrappers in 2004 in the United Kingdom. Displeased with that move Nestle took legal action against that protection.
There are many things that go into making a business successful. One of those things is consumers' recognition of products in the marketplace. Proper branding, accompanied by copyright and trademark registrations, can make a product more marketable and protect the business. Because of these benefits, it is fairly clear why a business would want to do whatever it could to maintain a copyright or trademark.
