I’ve noticed something about industrial/intellectual property marking: the bigger or more established the company or undertaking, the more understated the marking. For example, Mozilla Firefox’s about box (The traditional place for dropping IP notices) just has a small type note that “Firefox and the Firefox logos are trademarks of the Mozilla Foundation”.
In contrast, small time operators usually go overboard with the ©®™ stuff. I have decided to call this “hypermarking”. The thought of the thesis above came from my observing an example of it in, of all places, Microsoft Windows.
