Since ancient times, different industries have used different logos to distinguish them from other industries and even competitors. Nowadays, trademarks are also used to distinguish different types and uses of goods.

2. When trademark examiners examine trademarks, they will first search the trademark database. If they find that the same trademark has been applied for registration by more than one person on the same commodity or similar commodities, they will reject the enterprise or individual who applied after the application comes first.

4. Some enterprises or individuals are inexperienced, unfamiliar with the trademark registration process, and do not make approximate trademark inquiries before applying for trademark registration, resulting in the same situation of the applied trademark and the successfully registered trademark, thus losing the registration fee in vain.
