Legal analysis: Operating without authorization is an infringement. For example, if a certain brand restaurant is a franchise, you put up a signboard with its trademark to operate without authorization. For products without similar regulations, authorization is not required. For example, if you open a supermarket and sell drinks or something, you do not need authorization, and of course it does not constitute infringement.

Legal basis: Article 120 of the "People's Republic of China and Civil Code" If civil rights and interests are infringed, the infringed party has the right to request the infringer to bear tort liability.
