Are trademarks registered at state level accepted in the Clearinghouse?

Error message

Notice: unserialize(): Error at offset 0 of 1 bytes in variable_initialize() (line 1202 of /var/www/drupal/includes/bootstrap.inc).

State trademarks are not eligible for insertion in the Clearinghouse as trademarks need to be at least of national effect in order to be accepted in the Clearinghouse.  Trademarks registered by a city, state, province, or sub-national system will therefore not be accepted in the Clearinghouse. You can find more information about the Clearinghouse eligibility requirements in the Clearinghouse Guidelines.
