The Boyhood actress got a standing ovation by Meryl Streep during the ceremony on February 22 and much praise in the media.
In her answer to a question whether she had seen Ms Streep's reaction, Patricia, 46, said she had not but she later hugged the veteran actress.
She then went on to elaborate on her onstage comments, saying, "Even though we sort of feel like we have equal rights in America, right under the surface, there are huge issues that are applied that really do affect women. And it's time for all the women in America and all the men that love women, and all the gay people, and all the people of color that we've all fought for to fight for us now."

The comment sparked an instant reaction on Twitter with many expressing disappointment.
"People of colour have enjoyed freedom for so, so long and yet we continue to ignore the plight of downtrodden Patricia Arquettes. #ashamed," one user wrote.
Patricia later took to Twitter to defend her comments. She tweeted:
