1. Visual expression: Sound symbols need visual expression. Usually, trademark applicants need to provide visual representations containing sound symbols, such as notes, waveforms, music scores, etc. To ensure the clear display of sound signs.
2. Clarity: The visual expression of sound symbols should be clear enough so that others can understand and recognize sound symbols. This can ensure that the sound sign can be accurately recognized by the trademark registration bureau and the public.
3. Specificity and distinctiveness: Sound symbols need to have specificity and distinctiveness in order to distinguish them from other sounds and attract people's attention. Phonetic symbols should have unique audio characteristics to distinguish them from other phonetic symbols or ordinary sounds.
4. Does not involve functionality: Sound signs should not usually involve the functional characteristics of goods or services. Trademark registration offices generally tend to regard sound signs as specific sounds that identify the source of goods or services, rather than describing their functions or characteristics.
5. Identifiability: Sound signs need to have certain identifiability, so that the public can be associated with specific trademarks. Sound signs should be unique and recognizable enough to be recognized by consumers and associated with specific trademarks.
Please note that according to national and regional laws and regulations, the requirements for trademark registration of sound signs may be different. When applying for trademark registration of sound signs, it is recommended to consult the local trademark registration bureau or professional trademark agency for accurate requirements and guidance.
