This QA check ensures the preservation of copyright notices in translations. If the source text contains a copyright symbol (©), the term 'Copyright', or '(c)', the same should be present in the translated text. For instance, if the source text reads '© 2023 CompanyName', the translated text should also contain a corresponding copyright notice. If the source text does not contain a copyright notice, the translated text should also not contain one. The check will give a negative response if there is a mismatch in the presence of copyright notices between the source and the translated text.
