Status 710 means the registration was cancelled because a required Section 8 declaration of continued use was not filed within the deadline (including any grace period). The federal registration is no longer active. Evaluate filing a new application if you still use the mark, or petition if cancellation was erroneous. Consult counsel on remaining common-law rights.
If you own this trademark, we can monitor new filings and help with USPTO deadlines. If you do not, we can file a new U.S. application.
