Can I de-italicize specific phrases?

In a book I’m working on, all occurrences of a particular trademark are italicized, as requested by the licensor of a trademark I was planning to license. The license deal fell through, and I’d like to de-italicize that trademark going forward.

Is there any way to search and replace all the italicized versions of a particular word or phrase, throughout the project, with a non-italicized version?
