Hello, the first kind, the trademark that has not been registered in the preliminary examination stage, this is for sure, the trademark that has not been successfully registered must not be transferred, and we praise the trademark transfer on the bidding website. Com, have successfully registered r.

Second, if a trademark expires and the trademark fails to apply for renewal within the six-month' trademark renewal period', the Trademark Office will cancel the trademark. A trademark is valid and will be cancelled if it is not renewed. If it is cancelled, the trademark is definitely not transferable.

Third, if the trademark is changed but not changed, and the trademark needs to change its address, an application for change must be submitted to the Trademark Office. Or modify the text and pictures. If unauthorized changes are not submitted, the trademark will not be transferred successfully.

Fourth, if someone else has submitted a registered trademark to the Trademark Office and stopped using it for three consecutive years, the trademark that has been submitted for stopping using cannot be successfully transferred.

I hope the answer can help you, and I hope to adopt it ~, thank you!
