Nobody is trading with a business under those names, so they're not trademarks! Just like both Firefox and Internet Explorer can call a feature tabbed browsing, since neither of them are called the "Tabbed Browsing" browser.
Anyways, like Davio said, what would inverting an action do?? If you want, you can 'toggle' it which disables it, but it's only applicable to conditions, because it makes sense to say "condition NOT met" rather than "condition met".
