QGIS Trademark and brand guidelines

We’re thrilled that you want to refer to either the QGIS project or QGIS.ORG association and sincerely appreciate your help in spreading the word.

This page aims to provide you with all the information and resources you need for a correct use of the QGIS brand assets.

The QGIS name and logo are protected under European law from unauthorized and confusing uses of the trademark. You can find our trademark information at OAMI and EUIPO. Our main aim is to encourage those who do business using QGIS name and logo to participate actively in the project and help us to improve QGIS.

QGIS trademarks, service marks, logos and designs, as well as other works of authorship that are eligible for copyright protection (collectively termed “Marks”) are valuable assets that QGIS.ORG needs to protect. QGIS.ORG does not permit all uses of QGIS Marks. QGIS.ORG has posted these Trademark Usage Guidelines (“Guidelines”) to assist you in properly using our Marks in the specific cases that we do permit. The strength of our Marks depends, in part, upon consistent and appropriate use. We ask that you properly use and credit our Marks in accordance with these Guidelines. We reserve the right to change these Guidelines at any time solely at our discretion.

These Guidelines should be followed along with all QGIS’s rules and policies, posted on QGIS.ORG website or otherwise.

A permission is not a formal endorsement of your QGIS related project and doesn’t constitute a statement on the quality of your service.

  • Product names: If you plan to market a QGIS-based product or service to the public using a trademark or name that includes the word “QGIS”, such as “YourCompany QGIS” you are required to apply for and obtain a permission from the QGIS Project Steering Committee (QGIS-PSC). This is true whether or not you apply to register your trademark with a government. When developing and advertising QGIS-based products, we ask you to follow the following guidelines:
    1. Don’t present your work as our work: If you provide a customized QGIS version, make it clear that your offer is a derivative product, and not the official QGIS version by adding your company or brand name to the product name and accompanying text explaining that your product is a derivative as needed.
    2. Don’t present our work as your work: Give credit to the QGIS project where due. Don’t hide the fact that your product is based on QGIS.

  • Domain names and websites: Proper use of our Marks on websites to name or accurately describe QGIS’s products, services or technology is permitted. The use of our Marks should not be misleading or likely to cause confusion as to whether the website is sponsored by or affiliated with QGIS or whether the products, services or technology are offered by QGIS. QGIS Reserves the right to request you to remove our mark from your domain name, web site or publication if we deem it’s use to be inappropriate.
    1. Companies, products, and commercial projects cannot use a qgis.tld (top level domain): Any principal or secondary level domain name, with or without commercial intent, should not be identical to or virtually identical to any of our Marks.
    2. Companies, products, and commercial projects should preferably not to use ****qgis****.xxxx: The website owner should not register any domain name containing our Marks and should not claim any trademark or similar proprietary rights in the domain name.

Perguntas Frequentes

Q. Quando deve mostrar a atribuição apropriada?

A: Whenever and however you use the term QGIS in print, on the internet, or in audio broadcasts, you should always give proper attribution to QGIS project. For more information see “Trademark Attribution.”

Q: I am registering or have registered a trademark with my country’s trademark authority. Do I still need a permission?

A: Yes, assuming your trademark includes the element QGIS and it is being used in connection with software-related goods and services. Please note, the permission applies to QGIS trademark whether or not they are registered with a trademark authority. If you are using the term QGIS as a trademark (whether or not registered), you need to apply for a permission.

Q: I am a commercial entity (for example, a company, partnership or sole proprietor, profit or non-profit) selling software-related goods or services and using the word “QGIS” in the entity’s name. Do I need to apply for a permission?

A: Using QGIS in the entity’s name is not permitted because you are using QGIS as part of a trademark in connection with software-related goods or services. Software-related goods are computer programs and systems, or packages bundling software with tools, utilities, hardware, etc. Software-related services are services that deploy, document, facilitate the use of, or enhance computer programs and systems. Even if you don’t use QGIS as part of the entity’s name, if the entity has a product or service (whether sold or given away for free) that uses “QGIS” in its name, you still need a permission for the use of the word QGIS in the name of the products or services.

Q: * Se eu conseguir uma permissão para minha marca registrada, QGIS vai recusar a concessão de permissões semelhantes para as marcas que são idênticos ou confusamente similar a, minha marca ?*

A: No, QGIS will not attempt to ensure exclusivity or protect marks from infringement. QGIS considers the protection of trademarks against infringement to be the responsibility of the trademark owner. QGIS is not a dispute resolution authority, and does not become involved in disputes between trademark owners.

Q * Consentimento de Registro de Marcas: A minha organização solicitou para registrar uma marca para produtos ou serviços relacionados com software que inclui QGIS como um elemento. O pedido foi indeferido por confundir semelhança com a marca QGIS. Se eu entrar em uma permissão, QGIS dará consentimento para meu registro? *

A: No. The QGIS permission is not a consent for the registration of other trademarks. To protect the QGIS mark from dilution, we do not consent to the registration of trademarks found to be confusingly similar to the QGIS mark.
