Is it possible to write a story consisting entirely of trademarks? (Typed using only your middle fingers?)?

[Blues Einhander]

It actually depends on the use. A trademark is a word, phrase, logo or other symbol, used to identify a product, the source of a product and the manufacturer or merchant. A trademark is usually used to distinguish one product and its manufacturer from another.

Because trademarks are just symbols that represent a company, creating a book of these trademarks would per se be legal. That's because the only time infringement would occur is if a trademark is used to either market a similar good as the trademark's original purpose or trademark dilution occurs. Trademark dilution occurs when someone uses a well-established trademark for a different service, but either tarnishes the trademark's good name through the use or weakens the consumer's association between the trademark and the services.

The latter situation would be more apt to a book's liability. So if you made a book full of trademarks and specifically used those trademarks to tarnish the reputation of the trademark's owner with your book, then that would be infringement and it would be illegal to publish a book full of trademarks.
