The company proved that it had been using the name since 1994 and had achieved market resonance with it across titles featuring Briana Banks, Jenna Jameson, Jesse Jane, Devon, and Tera Patrick.
Digital Playground's president, Samantha Lewis, reported that the trademark registration became official last November.
"We have been using the Virtual Sex® mark in association with our products since at least 1994," she said. "So far, we have successfully policed our mark, and have had infringing products removed from the marketplace."
