Passing compatibility tests—or simply claiming LSB compatibility—does not by itself let a company call a product “LSB Certified” or use an LSB certification logo. The Linux Foundation requires successful compliance testing, explicit authorization, and an executed trademark license. The LSB-specific guideline page is archival, so check the Foundation’s current trademark policy before using the name or artwork.
When can a product be called LSB-certified?
Only after the company has met all of the Linux Foundation’s stated conditions: it must successfully complete the Foundation’s compliance-testing suites, receive explicit authorization to use the certification wording and marks, and execute the Foundation’s Trademark License. The LSB Trademark Guidelines expressly warn against describing a product or service as LF- or LSB-certified, or using LF certification marks, unless those conditions have been satisfied.
Technical compatibility alone is not permission to use certification language. The related LSB certification documentation says certification placed an application on the Linux Foundation’s official certified list and required makers of certified products to agree to a Trademark License Agreement covering the “LSB Certified” term and associated logos.
What does the LSB trademark page cover?
The LSB-specific page provides rules for certification terminology and logo reproduction. It is not a substitute for the Linux Foundation’s broader trademark policy: the page directs readers to that overall guidance for current trademark requirements.

#1 Best Overall
The LSB page was last modified on July 20, 2016, according to its revision record. Treat its asset links and production details as historical guidance, not proof that a particular logo file or permission is currently available. The Linux Foundation’s current trademark usage policy is the relevant starting point for present-day use. Its trademark register was updated November 19, 2024, as shown in the register.
How should Linux Foundation marks be used?
The current Foundation policy says trademarks should be used as adjectives with a generic noun, rather than as standalone nouns or verbs. It also restricts changing or combining marks, abbreviating them, using them in domain names or product names, and presenting them in a way that implies sponsorship or certification where none exists. These rules are intended to preserve the marks’ assurance of consistent quality; the Foundation states that trademarks provide assurance of “consistency with respect to the quality of products or services with which the mark is associated.”
Rank #2
For an LSB certification claim, follow the more specific authorization and licensing requirements as well as the general usage rules. If approval or license status is unclear, do not publish certification wording or display a certification mark until the Linux Foundation confirms permission.
What colors does the LSB page specify?
The archival page gives these reproduction specifications. In every listed color version, the version text, such as “3.x,” remains white.

The page prefers color reproduction where practicable. It also allows monochrome use that highlights the logo with a border, and reversal in white or another pale color. Consult the current policy and obtain any required approval before producing or distributing certification artwork.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Which LSB logo files are linked?
The LSB guideline page links logo downloads for versions 3.0, 3.1, 3.2, 4.0, and 4.1. It also directs readers to trademark contacts for other high-resolution forms. Because the page’s last recorded modification was in 2016, verify that a linked file is still the authorized asset for your use; a downloadable file is not, by itself, a trademark license or permission to claim certification.
Quick Recap
Best Value
Practical compliance check
- Confirm the status. Establish that the company completed the Linux Foundation’s applicable compliance-testing suites.
- Obtain explicit authorization. Do not infer permission from a test result, technical compatibility, or the existence of a logo download.
- Execute the trademark license. Confirm the required Trademark License is in place for the wording and marks you intend to use.
- Check current usage rules. Review the Linux Foundation’s current trademark policy and confirm the applicable logo asset and version.
- Review the presentation. Use the mark only within the authorized scope, follow the applicable reproduction guidance, and avoid wording or placement that implies unsupported certification or sponsorship.
