First of all, talk about the trademark rejection review. Generally, when an applicant's trademark is similar to someone else's trademark because of its similarity in graphics, words or categories, the Trademark Office will reject the registered trademark according to the application time. After receiving the notice of rejection, the applicant may consider whether to conduct a re-examination according to the reasons given by the State Trademark Office. The time for reexamination of trademark rejection is generally subject to the ruling documents of the Trademark Review and Adjudication Board, and it usually takes 6-8 months to get the results. Trademark rejection review also plays a great role. For example, if the applicant refuses to accept the state's reasons for rejection, he can fully expound his reasons and opinions again through review, and provide corresponding evidence as supporting materials. Another function is to delay time effectively. Some trademarks are applied by the same applicant, but due to the change of the applicant's name, it is impossible to apply to the Trademark Office for change in time. You can explain the situation through the Trademark Review and Adjudication Board and go through the relevant procedures. As for the success rate of trademark rejection review, it depends on the review committee and relevant review criteria, because it is manual review. Therefore, there is still subjectivity. Different people have different opinions. But it will be more objective than the timely examination of trademark applications. An experienced intellectual property agency will judge the reason why your trademark was rejected and see if there is a chance to register it. It seems that Pig Bajie Intellectual Property has this business. Of course, it is best to check the progress of this trademark or other similar trademarks on the signpost website first, or you can estimate whether it needs to be rejected first.
