First of all, I want to clarify a concept here. The necessary quotation is not plagiarism. Plagiarism has two meanings: one is direct plagiarism and the other is word for word plagiarism. Of course, this is the lowest level of plagiarism. The second is plagiarism in thinking, logic and structure. The essential difference between originality and plagiarism lies in whether you have your own thoughts. In short, originality must be innovation.
Packaging infringement should include:
1. The packaging used infringes others' patent right of utility model (the packaging is creative) or design;
2. There is a trademark on the package used, which infringes the exclusive right to use a trademark owned by others.
In addition, it may deliberately imitate the unique packaging of other people's well-known goods, which is suspected of unfair competition.
