The so-called reverse confusion (REVERSE CONFUSION) is opposite to confusion (forward confusion) in the traditional sense, that is, the subsequent use of the trademark by the trademark user has made it have a higher degree of confusion. It is so well-known that consumers will mistakenly believe that the goods of the former trademark user come from the later trademark user or that there is some kind of sponsorship or endorsement connection between the two. In practice, a later trademark user may use someone else's previously registered trademark as a trademark, trade name, product name and other commercial identifiers.
