| |
| This document (the "Guidelines") contains guidelines for use of the CentOS word mark (the "Word Mark"), as well as the CentOS logotype, the CentOS graphical symbol, the & |
| |
| The CentOS Marks are trademarks of Red Hat, Inc. ("Red Hat"). Trademarks provide assurance about the quality of the goods or services with which the trademarks are associated. Confusion can arise if the same or similar names are used on identical or similar offerings. Red Hat& |
| |
| These Guidelines aim to provide sufficient clarity for you to understand whether your use of the CentOS Marks will be acceptable. |
| Nothing in these Guidelines limits your permissions under the open source or other copyright licenses covering packages in any CentOS software distribution. |
| |
| The CentOS Project is by its nature a noncommercial community project that provides software free of charge, even though the copyright licenses covering the individual component packages that comprise the CentOS software distribution may permit commercial use. |
| |
| |
| |
| Red Hat welcomes the assistance of the entire CentOS community in reporting non-compliant uses of the CentOS Marks and in encouraging those engaged in non-compliant uses to take corrective measures. |
| |
| |
| |
| Whenever you use the CentOS Marks, you must do so in a way that does not mislead others, either directly or by omission, concerning what they are obtaining and from whom. The law reflects this requirement in two principal ways: it prohibits creation of a "likelihood of confusion" but allows for "nominative use". |
| |
| For example, you are not allowed to say you are distributing CentOS software when you are actually distributing some downstream modification of an official CentOS release ("Official" packages, builds, and releases are those that have been approved for the CentOS Project& |
| |
| You may not use or register, in whole or in part, the CentOS Marks as part of your own trademark, service mark, domain name, company name, trade name, product name, or service name. |
| |
| Trademark law does not allow your use of names or trademarks that are confusingly similar to the CentOS Marks. This means, among other things, that you may not use a variation of any of the CentOS Marks or any phonetic equivalent, takeoff, or abbreviation for a similar or related project, product, or service. |

| Unacceptable uses |
| |
| Notwithstanding anything to the contrary provided in these Guidelines, the following are examples of unacceptable uses: |
| |
| 1. Use of the CentOS Marks in connection with commercial redistribution of CentOS software (Commercial redistribution includes, by way of example but is not limited to, redistribution in connection with any commercial business activities or revenue-generating business activities.) , regardless of whether the CentOS software is unmodified, except as may be permitted above. |
| |
| 2. Use of the CentOS Marks to identify software that combines any portion of the CentOS software with any other software , unless the combined distribution is an official CentOS distribution. For example, you may not distribute a combination of the CentOS software with software released by the FooStack project under the name "CentOS FooStack Distro". |
| |
| 3. Use of the CentOS Marks in connection with any rebuild of CentOS software, unless such rebuild is an official CentOS build, regardless of whether the CentOS software is unmodified. |
