To judge whether a trademark is infringing, we should first look at whether two trademarks are the same or similar. Generally speaking, to judge whether two trademarks are similar, we should make a comprehensive comparison from the aspects of sound, shape, meaning and overall structure of the two trademarks, and at the same time, we should combine specific cases. Your trademark is more or less than someone else's registered trademark by a word, a letter and a symbol. You can't say that you must have infringed the trademark rights of others.
