Xen Project Style Guide

Updated June 13, 2014

The Linux Foundation owns the "Xen Project" trademark. Citrix still owns the "Xen" trademark and uses it for many variations of their products.

The following are basic rules that are important in protecting trademarks and service marks. These rules should be followed in all news releases, web site, presentation and marketing collateral.

Use Marks As Adjectives - Not As Nouns

Trademarks are adjectives that modify a generic noun. If you remove the mark and the sentence still works, it is probably being used correctly. Using a mark as an adjective is simple -- simply have the common descriptive name (noun) of the product or service follow the mark. This should be done throughout all material, not just on first reference.

Example of correct trademark usage: Buy TIDE detergent for whiter clothes.
Example of incorrect trademark usage: Buy TIDE for whiter clothes.

Correct: Download the Xen Project hypervisor.
Incorrect: Download the Xen hypervisor.
Correct: We use Xen Project software.
Incorrect: The Xen Project produces software. ("Xen Project" is being used as a noun).

Using a mark as an adjective is important because you do not want your mark to become the generic name for the product, like aspirin, escalator, thermos, and countless others.

Do Not Use Marks In The Possessive

Because trademarks are not nouns, they should not be used in the possessive.

Correct: The Xen Project leaders...
Incorrect: Xen Project’s leaders

Using the new style guide rules, we revised sample web site copy for a trial run with the new wording. We’ve also developed a new introduction for news releases.
