Maintainers' Contract


Primarily based on trademark law, this Contract covers the uses of Distinctive Marks (both registered and unregistered) where such uses are carried out as an economic activity including any reputational gains made by using the initiator's goodwill, or the delivery of improved technical services to any beneficiary who may have requested specific software enhancements or service improvements.

This Contract aims to be compatible with both FOSSmarks (available on and Model Trademark Guidelines (available on projects. However, should any conflict in meaning arise, the provisions of this Contract shall be interpreted in full favour of the rights it grants here.

This Maintainers Contract (the "Contract") applies to any Distinctive Mark as associated with the Programme and its Open Source Licence, with no prejudice to the rights given on the Programme by its Open Source Licence.

This Maintainers' Contract also aims, by specifying it, to harmonise the international application of fair use, particularly about reference purposes.

All intellectual property rights attached to, resulted from, caused by or relevant to the Distinctive Mark are covered under this Contract. The Contract also covers the following Distinctive Mark aspects:


The parties to this Contract agree that whether unregistered or registered nationally, regionally or internationally, the Distinctive Mark will enjoy full trademark law protection. The trademark holder is entitled to the exclusive right to the use of the registered trademark, for the legal duration of the trademark registration.

The parties to this Contract agree that any copyright or neighbouring rights associated with the Distinctive Mark is fully protected by copyright law. Where relevant, the licensed Distinctive Mark in this Contract covers all individual elements of copyright and neighbouring rights. The parties to this Contract intend it to include economic and moral rights as granted by law and/or this Contract for original works of authorship fixed in a tangible medium of expression.

The parties to this Contract agree and recognise that it includes a non-exclusive licence to any relevant registered design that is held by, under the control of, or sub-licensable by the Initiator, to the extent necessary to facilitate making use of the rights granted under this Contract.


Subject to the terms and conditions of this Contract and its Sections 2 and 4-7, the Initiator grants to the Licencee a license on all Intellectual Property Rights described in Section 2 in order to Use the Distinctive Mark in accordance with Section 5-12 including the rights to * provide and supply third parties with Products and/or Associated Services for a fee or any other consideration, including without limitation hosting fees, consultation fees or charges for support services, related to the supply of Programmes, Products and/or Associated Services; * advertise, endorse and promote Products, Associated Services or any legal entity, in any medium (such as domain name or URL) in the business forum relevant to Product and/or Associated Services; and

In order to cover all Intellectual Property Rights described above, specific licenses are detailed below. The scope of their grants should be interpreted consistently.




Notwithstanding any other provision of this agreement, this Contract does not relate to the Programme itself which remains available under the Free and Open Source Licence. This Contract shall not be interpreted in any way to limit the rights given by the Open Source Licence.

This Contract only applies to the use of the Trademark, with no prejudice to Fair use doctrine.

Anyone who wishes to use the Program under the terms of the Free and Open Source License under which it is distributed is granted the right to remove any reference to the Program's Trademark from the source code and naming of files and components, so that they may exercise their rights under the Free and Open Source License without restriction.


Notwithstanding any other provision of this agreement, this Contract does not cover, license, permit the use of, or give access to any patents owned by the Initiator.


Notwithstanding any other provision of this agreement, this Contract cannot be interpreted in any way that would create an unfair advantage to any party. The Contract is not discriminatory and everybody should have the rights to use the Distinctive Mark in accordance to this Contract, either to provide Associated Services (subject to Section 6) or to answer any call for tender requiring the Commercial Intermediary to comply with the Contract (Subsection 7.3).


Notwithstanding Sections 2 and 3, or any other provision of this agreement, this Contract does not cover or permit the Use of Similar Marks or the Use of Distinctive Marks on a modified Product or on any products or services other than the Products and Associated Services set forth in this Contract.


The Contract grants a licence for the duration of the legal rights covered as described in Subsection 2.2. To the extent possible in the relevant jurisdiction, the rights may be exercised in any medium or format whether now known or created in the future. This right explicitly includes commercial use, but do not exclude any field of commercial activity.


The right to Use the Distinctive Mark under different terms is reserved. In the event that the Distinctive Mark is multiple-licenced the Licencee has the choice of using alternative licences. These uses and their terms of use might be detailed within the Trademark Policy. The Initiator does not grant any licence for the use of Similar Mark. Such use is totally forbidden unless it results from the conditions detailed in Section 6.

The Licencee is not permitted to Use the Distinctive Mark or Similar Mark regarding products or services not related to the Program: * in any way or form which attempts to unfairly or unjustifiably capitalise on the Initiator's goodwill or brand including without limitation an attempt to imply an endorsement that does not exist; * as part of or as its corporate or trading name; or * incorporate in its business.

For reference purposes only, such Use is permitted only to the extent needed to explain the link with the Programme. In this case, a weblink must be provided to offer recipients a link to the Initiator's webpage or the one(s) dedicated to the Programme or Product should there be one. For instance, the Licencee is permitted to say: "This Product is compatible with Word Mark Progamme." or "System Management Tool for Programme Name" or "Programme Name-Based System Management Tool."



Private Use of the Distinctive Mark is unconditionally permitted on a royalty-free basis. Private Use covers all forms of internal use of the Programme including Software as a Service Offering (SaaS Offering) unless such activity is conducted as part of Associated Services offering or exploitation.


In order to comply with this Contract, each Use of the Distinctive Mark by the Licencee shall strictly be conducted as outlined below:





In no event and under no legal theory, whether in tort (including negligence), contract, or otherwise, unless required by applicable law or expressly mentioned in this Contract, shall the Initiator, its owner(s), employee(s), subcontractor(s), freelancer(s) or any person, even if advised of the possibility of such damages, be liable for any loss, expense or damage, of any type or nature including direct, indirect, incidental, special, exemplary, or consequential loss or damages of any character (including albeit without limitation to lost profits), however caused or arising from the Licencee\'s exercise of the rights granted in this Contract, or as a result of this Contract or out of the Use or inability to Use the Product.



All Licencee's rights granted under this Contract shall be void and this Contract shall terminate if the Licencee fails to comply with any of the material terms or conditions of this Contract and/or the Free and Open Source Licence, unless such breach is rectified by the Lisensee within a reasonable period of time after the Licencee becomes aware of such non-compliance issue.



If any provision of this Contract be held invalid, illegal or unenforceable under applicable law by a court of competent jurisdiction, such invalidity shall not affect the validity, operation or enforceability of the remainder of the terms of this Contract. Rather, and without further action by the parties hereto, the invalid, illegal, or unenforceable provision shall be modified to the extent necessary so that it is valid, legal, and enforceable.


All rights not expressly granted under this Contract are reserved. Nothing in this Contract is intended to be enforceable by any entity not a Licencee nor the Initiator. No third party or Beneficiary rights are created under this Contract.


The Licencee covenants with the Initiator not to do or omit or suffer to be done any act that will or may weaken, damage or be detrimental to the Distinctive Mark or the reputation or goodwill associated with the Distinctive Mark or the Initiator, or that may invalidate or jeopardise any current or potential registration of the Distinctive Mark.



Nothing in this Contract is intended to or shall be deemed or construed by its parties or by any other entity to create an agency or any type of partnership or joint venture between any of its parties, or authorise any party to make or enter into any commitments for or on behalf of any other party of this Contract.


The Licencee acknowledges its full comprehension and understanding of the terms and conditions of this Contract. The Licencee also confirms it is acting on its own behalf and not for the benefit of any other person or entity.
