HOUSTON, September 23, 2026 – Baker Botts L.L.P., a leading international energy, technology, and life sciences law firm, secured a complete victory for its pro bono clients in a federal copyright and trademark dispute involving two quinceañera dress businesses.

Baker Botts entered the case shortly before trial to represent Jacqueline G. Espinoza and Estilo Isabella LLC in Viann’ K Mansur LLC v. Estilo Isabella LLC and Jacqueline G. Espinoza, Case No. 4:23-CV-2914, in the U.S. District Court for the Southern District of Texas.

The firm first used pretrial motion practice and negotiations to secure a favorable settlement for Espinoza. Baker Botts continued defending Estilo Isabella against the plaintiffs’ remaining claims for damages and other relief.

Following multiple rounds of briefing and a three-hour evidentiary hearing featuring live witness testimony and closing arguments, U.S. District Judge Ewing Werlein Jr. ruled from the bench, denying the plaintiff’s requests for damages, a permanent injunction and attorneys’ fees.

Houston litigation associates Lexie Ammons and Elizabeth Pegg led the firm’s day-to-day representation, preparing the case for the evidentiary hearing on an expedited schedule.

“Pro bono service is central to who we are as a firm, especially when someone is facing a critical proceeding without counsel,” said Baker Botts Partner Amy Hefley. “Lexie and Elizabeth answered that call with skill, determination and sound judgment. Their advocacy made a life-changing difference for our client and reflects the very best of Baker Botts.”

“Being able to step in, prepare for trial and an evidentiary hearing, and ultimately secure a complete victory is a reminder of why pro bono work matters,” Ammons said. “Everyone deserves representation.”
