1.? Trademark law: reselling other people's goods may infringe the rights and interests of trademark owners. Trademark law protects the exclusive right of trademark owners to their trademarks, including prohibiting others from using, selling or reselling goods bearing the trademarks without authorization.
2.? Copyright law: If the resold goods involve works protected by copyright (such as works of art, books, music, etc.). ), then unauthorized resale may infringe the rights and interests of the copyright owner.
3.? Patent Law: If the resold goods are protected by patents, then unauthorized resale may constitute patent infringement.
4.? Unfair Competition Law: Reselling other people's goods may be regarded as unfair competition, especially when the resale sells goods at a price lower than the normal market price, thus causing competitive damage to the original manufacturer or authorized dealer.
The specific application of the law and the determination of illegal acts will be different according to the legal systems of different countries and regions. In addition, in some cases, it may be legal to resell other people's goods, for example, to resell goods owned by individuals in the second-hand market.
If you have specific resale behavior or need to consult, it is recommended to consult local legal professionals for accurate legal advice and guidance.
