The trademark preliminary examination announcement is reviewed and approved by the Trademark Office. There is a three-month announcement period after the preliminary examination announcement.
After the announcement period is the registration announcement. The registration announcement means that the trademark application has been successfully completed. Just wait for the typesetting and printing of the trademark registration certificate to be issued. If you are talking about the registration announcement, it means that the application has been successful and you just need to wait for the Trademark Office to issue the registration certificate.
The registration certificate will only be issued around June 2015. If yours has just been announced, you may have to wait for a while.
