Under normal circumstances, the Trademark Office will issue a certificate of transfer in about 6-8 months and make an announcement on the transfer of the trademark. The date of signature on the certificate is the date of announcement, and the transferee enjoys the exclusive right to use the trademark from that date. The original trademark certificate and the transfer certificate are used together. If the trademark transfer is rejected, you need to complete the information and resubmit the transfer application, so the time required for trademark transfer depends on the situation.
