Trademark registration review may have certain differences according to the trademark laws and regulations of different countries or regions, but generally follows the following principles:

1. Principle of similarity: Trademark registration review focuses on judging trademarks Whether it is similar or identical to a registered trademark or a previously applied trademark. Similarity includes similarity in appearance, pronunciation, and meaning. If a trademark is too similar to an existing trademark, it may be considered to cause confusion.

2. Principle of uniqueness: Trademark registration review requires that the trademark be sufficiently unique, that is, it can be clearly distinguished from other trademarks. Trademarks should have unique graphics, words, letters, numbers, combinations or other identifying elements to ensure trademark recognition.

3. Principle of distinguishability: Trademark registration review requires that the trademark be able to distinguish consumers from other goods or services without causing confusion. A trademark should be sufficiently identifiable and distinctive to enable consumers to accurately identify the source represented by the trademark.

4. Principle of illegality and prohibition: Trademark registration review requires that trademarks must not violate national or regional laws and regulations, including not violating public order and good customs, not infringing on the rights and interests of others, and not being illegal, obscene, offensive or moral. Unacceptable content.

5. Principle of graphic expression: Trademark registration review requires that the trademark can be presented graphically and be accurately represented, copied and identified. The graphical expression of the trademark should comply with the requirements of the Trademark Office to ensure that the trademark can be correctly expressed on the trademark registration certificate.

The principles of trademark registration review are designed to protect trademark rights and avoid confusion and infringement. During the trademark registration application process, the Trademark Office will evaluate and review the trademark based on these principles to ensure that the trademark meets the registration requirements.
