In trademark registration, if two trademarks have the same sound but different characters, it is usually possible to apply.

The protection scope of a trademark is not limited to literal similarity, but also includes sound, graphics, color and so on. When two trademarks are very similar in pronunciation, can cause confusion or produce similar concepts, the Trademark Registration Office may consider that they are similar.

Therefore, as long as the two trademarks are very similar in pronunciation, you can apply for registration even if the words are different. For example, "Apple" and "Apollo" are very similar in pronunciation, although they are different in words, and may be considered as similar.

However, it should be noted that the Trademark Registration Office will conduct detailed trademark similarity comparison and review to determine whether there is any possibility of confusion. They will consider the overall impression of the trademark, the similarity of pronunciation, the similarity of goods or services and other factors to make a decision.

It is best to conduct trademark search and similarity evaluation before trademark registration to find out whether there are similar or similar trademarks. In addition, consulting a professional intellectual property lawyer or trademark agency can provide more detailed legal advice and guidance to help you determine whether you can apply for registration of a trademark with the same sound but different characters.
