2. Trademark infringement: Many enterprises will use trademarks of well-known brands or similar trademarks when producing and selling tea, which may lead to the risk of trademark infringement.
3. Misappropriation of geographical indications: Many tea products in China have geographical indications, but false geographical indications or unauthorized use often appear in the market, which may affect consumers' trust and value of the tea products.
4. Infringement of others' patent rights: If a certain tea adopts patented technology owned by other companies, it may constitute infringement of others' patent rights.
5. Fake and shoddy products: There are a large number of fake and shoddy products in the tea market, which not only has potential intellectual property risks, but also may harm consumers' rights and interests.
