The state argued in a brief filed Friday with the U.S. Patent and Trademark Office that it is the rightful owner of the trademark. The state says the Daughters' application would likely cause confusion.
After finding out the Daughters -- longtime custodians of the state-owned Alamo -- had filed for the trademark, the state had asked for a time extension to look into the matter.
The Daughters now have until Sept. 1 to answer the state's opposition. A call to the Daughters' president general was not immediately returned Monday.
