Slightly off-topic, but still of interest, I hope:
Xerox, the brand-name for a type of photocopier.
Band-Aid, the brand-name for a type of bandage.
Jell-O, the brand-name for a gelatin dessert.
All three company's brand-names are frequently used to generically describe similar products. All three companies are in a protracted struggle to maintain their legal marks. Xerox seems to be fighting a losing battle because several prominent dictionaries list xerox as a verb for making a photocopy of something and Xerox has been unable to put a stop to it.
