Graphic retrieval has always been a difficult problem in trademarks, because it is still difficult for computers to identify graphics, unlike words, which have fixed results when querying. There are graphics, you say a tree and a person, how can a computer distinguish it? Therefore, many graphic retrieval pieces have to be done manually. Under the current technical background, they can only rely on manual work, which is also the reason for the high registration price of graphic trademarks! It is recommended to make manual inquiry directly, and personally recommend window zero. They are more professional in trademark inquiry.
