Trademark registration is a process and has many stages involved in the process. This is those one of the stages which comes after filing of trademark application, wherein the trademark Examiner examines the trademark application and while checking, they have reasons to object the application and ask for clarification on certain points. The registry uploads a copy of Examination Report on their official website (trademark application status) and sends a letter to the applicant asking for reply mandatorily within 30 days from the date of issuance of objection. Failing on time reply shall be result in ABANDONED of your application.
After Abandonment there is no option to revive it rather than to file a fresh application and to follow the entire process again.
After the successful submission of objection reply, the Trademark examiner takes the reply submitted into consideration and finds the reply sufficient and addresses all the concerns raised in the Examination Report, the application would be allowed to proceed for the next stage which is publication in the Trademark Journal, before registration.
