1, trademark inquiry. Trademark inquiry refers to the inquiry whether the trademark applied by the applicant for trademark registration or his agent is the same as or similar to the trademark with prior rights before applying for registration. The following situations are explained here: 1) words that lack distinctiveness or are prohibited by the trademark law cannot be queried to determine whether their registration application can be approved; 2) If the trademark identical or similar to the previous application has not entered the database of the Trademark Office at the time of inquiry, the inquiry result will not be reflected because of the two approximations; 3) If the inquiry report provides several possible similar trademarks, the agent only makes an analysis through general examination standards and experience, and his opinions are for reference only and cannot represent the examination opinions of the Trademark Office; 4) For a combined trademark, if only a part of the trademark (such as Chinese or English) is inquired, but other parts of the trademark actually applied for (such as graphics) are the same as or similar to the registered trademark of others, the whole trademark will be rejected; 5) The client only provided the name of the trademark when inquiring, but the differences in font, color, structure or arrangement of the trademark design drafts provided in the actual application will also lead to the query results not completely reflecting the same or similar degree. 2. Trademark review. Trademark review is divided into formal review and substantive review.
