The Linux Foundation has registered Hyperledger® as a trademark in the United States and other countries. Please use ® with the first mention of Hyperledger in all materials. The below guidelines apply to use of other Hyperledger trademarks. The Linux Foundation Trademark Usage Guidelines, available at www.linuxfoundation.org/trademark-usage, also apply to any use of the Hyperledger trademarks.
Rules and Policies Applicable to Hyperledger Marks Owned by The Linux Foundation
In addition to the generally applicable rules discussed in The Linux Foundation Trademark Usage Guidelines, there are a few specific rules that we ask everyone to follow when using trademarks related to one of the Hyperledger projects or the organization itself.
- Do mention The Linux Foundation with the first use of Hyperledger in formal materials (e.g., “Hyperledger, hosted by The Linux Foundation”) and do use “Hyperledger” when referring to the organization (e.g., “Acme is a member of Hyperledger” or “Acme is a member of the Hyperledger consortium”).
- When referring to a specific Hyperledger software project, do use the full project name (e.g., “Acme uses Hyperledger Iroha”) and do refer to it as a “framework” or a “tool,” as appropriate (e.g., “the Hyperledger Iroha framework”, “the Hyperledger Explorer tool”).
- Do help promote Hyperledger in a vendor-neutral way. Where necessary to highlight the initial code contributor, do use the name of the codebase followed by “the technology initially contributed by …” (e.g., “Hyperledger Fabric, the technology initially contributed by …”). Do mention that there are __ projects hosted by the Hyperledger organization when mentioning one specific project, where possible (the current number of projects hosted can be found at hyperledger.org).
- Do let Hyperledger staff know if you plan an event or are putting out a press release centered around or mentioning Hyperledger and contact us if you have any questions about proper trademark use. Do introduce a meetup or event with the short Hyperledger official introductory presentation, available under the presentations section of the resource center here: https://www.hyperledger.org/resources/publications.
- Don’t use “Hyperledger Project” to refer to the organization. As noted above, Hyperledger hosts many software projects. Similarly, don’t use “Hyperledger Project” when you are referring to a specific project hosted by Hyperledger (e.g., “Acme did a proof of concept on Hyperledger” should be “Acme did a proof of concept on the Hyperledger Iroha framework”).
- Don’t modify the Hyperledger trademarks or logos (e.g., do not abbreviate them, add hyphens or other characters, or change the colors, orientation or any other visual aspect of any logos).
- Don’t use any Hyperledger trademark in a misleading way, which includes the following:
- Don’t use Hyperledger trademarks in connection with any products or services that are not related to, built for or associated with the software projects hosted by the Hyperledger organization.
- Don’t use your company name possessively with the Hyperledger organization or a specific hosted project (e.g., “Acme’s Hyperledger,” “Acme’s Fabric,” “Iroha by Acme,” “Acme’s Hyperledger Project,” “Acme’s Hyperledger Sawtooth”).
- Don’t add your company logo(s) on Hyperledger marketing materials, such as official presentations, unless expressly permitted to do so by Hyperledger staff. Don’t create marketing materials that look like they are coming from Hyperledger rather than your company.
- Don’t use the Hyperledger logo larger than your own company’s logo(s).
- Don’t use the Hyperledger trademarks in a way that creates a sense of endorsement, sponsorship, or false association with Hyperledger (e.g., “Hyperledger approved,” “Hyperledger certified,” “a product by a Hyperledger member”) or in connection with a project that has not been accepted into the Hyperledger organization.
- Don’t use a Hyperledger trademark in connection with a Meetup with 3 or more speakers from the same company; use the company’s trademarks.
- Don’t deliberately give the impression that a company is the “main” company behind Hyperledger, associate Hyperledger with a single project or company, or is otherwise harmful to the organization, its members or other projects.
The Hyperledger marks have been created and their use is expressly permitted for a specific purpose. Do not use Hyperledger logos or names in any commercial or marketing context other than as expressly permitted in this policy or The Linux Foundation Trademark Usage Guidelines unless you have obtained explicit written permission from the Hyperledger organization to do so.
Guidelines for Products/Services Built with Hyperledger Technologies
- Do use the following format and wording to describe how Hyperledger projects support a product or service offering:
- [Vendor name] [Product name] [Product version]* for -OR- based on -OR- powered by Hyperledger [Project] [Project version]*
- *Product Version and Project Version are optional for marketing materials, but must be included in tech specs
- E.g. Acme Blockchain Services (v1.4) powered by Hyperledger Fabric (v1.0)
- All press releases that use the Hyperledger trademark and common-law marks for our projects are required to be passed by the Hyperledger PR team for approval at email@example.com.
- You may not use our marks in domain names for products or services related to Hyperledger without prior approval. Nor can you use brands on your own web pages in a way that represents a product or service offering, without our prior approval. Obtain approval via firstname.lastname@example.org.
- We also strongly recommend that if you prepare marketing collateral within which you plan to use the words “Hyperledger” or any of our project brands, submit to email@example.com for discussion and approval.
