China's existing legal system, including the Anti-Unfair Competition Law, does not define logo production, and its trademark is registered by others. As a key chain pendant, necklace pendant and small backpack, it is defined as typed unfair competition, so we can only consider whether it constitutes untyped unfair competition. To judge whether it constitutes untyped unfair competition, we must first judge whether the trademark owner has interests that should be protected by law, and obviously his interests cannot be those that have been protected by the Trademark Law (to prevent confusion and dilution).

Without infringing the exclusive right to use registered trademarks of others, it should not be easily identified as unfair competition. How to standardize the identification of the production of registered trademarks of others as key chain pendants, necklace pendants and small backpack? If the logo of a registered trademark conforms to the constitutive requirements of the work and does not exceed the protection period, the path of copyright protection can be claimed.
