Intel is famous for being overly aggressive in trying to enforce its trademark, often claiming rights over almost any
use of the prefix "intel" to anyone using the phrase "something inside," even if it's completely unrelated to the business that Intel is in. Trademark, of course, is not intended to give a company "ownership" of a word or phrase. Instead, it's a consumer protection system, designed to prevent consumers from being tricked into believing that they're buying a good from one company instead of another. That's why trademarks are only applicable in the business area that the company is using the mark. Thus, Johnny's Soda doesn't interfere with a trademark on Johnny's Dry Cleaning -- because they're totally separate businesses. That's also why we have the moron in a hurry
test. If a "moron in a hurry" is unlikely to be confused by the use of the mark, then there's no trademark infringement.
Unfortunately, that hasn't stopped Intel from trying. Over the years they've gone after a maker of jeans
(Intel Jeans), a marketing firm
(for using the term INTELMARK for one of its products) and an artist's cooperative
for using the name "Art Inside") among various other cases over the years. Its latest is to go after a travel agency called Intellife Travel
that books trips between the US and China. The travel agency clearly explained to Intel that unless Intel's trademark covered the travel business, there was unlikely to be any infringement. Intel took a year to think about it... and then filed a lawsuit. Hopefully, Intel gets smacked down quickly on this clear abuse of trademark law.
