What this means
These status codes mean the trademark application is abandoned and no longer pending. Common reasons include missing an Office Action response (600), filing without a valid basis (602), express abandonment by the applicant (604), or failure to respond to an examiner's inquiry (618). Revival may be possible in limited circumstances. If abandonment was unintentional, consult counsel about a petition to revive. Otherwise file a new application if protection is still needed.
