Khronos Trademark Guidelines April 2010

1. Background

Khronos owns, or has licensed, trademarks used to identify its activities and specifications – for example the OpenGL® mark. The trademarks used by Khronos are collectively referred to as the Khronos Marks. Khronos maintains strict control over usage of the Khronos Marks to protect the integrity of its specifications. This document defines who may use the Khronos Marks, and under what terms and conditions.

Khronos Marks are protected in both text and logo form. For example, the text string “OpenGL” is a trademark - as is the OpenGL logo. In addition, Khronos may make available Certification Logos available for use on fully conformant products.

To assure that implementations of Khronos specifications meet a consistent standard of the highest quality, the Khronos Group maintains Adopter Programs that provide access to conformance tests for verification by Khronos that a product or implementation conforms to the specification. Any party who wishes to market and distribute an implementation that is identified by use of a Khronos Mark (in text or logo form) must execute the Khronos Adopters Agreement and successfully pass the implementation through the conformance testing procedure as defined in the Khronos Conformance Process Document.

A Khronos Member has a current Promoter or Contributor membership of the Khronos Group, and an Adopter has executed a Khronos Adopters Agreement for a specific specification and has paid any associated Adopters fees. You do not have to be a Khronos Member to be an Adopter – and vice versa.

2. Use of Khronos Marks NOT Related to a Product or Platform

Companies or individuals that are not members of Khronos and who wish to use a Khronos Mark for promotional or educational purposes are welcome to apply for a Khronos Non-Member Trademark License at www.khronos.org/trademarks. Grant of the Non-Member Trademark License is at Khronos’ sole discretion and specifically excludes any usage of a Khronos Mark (in text or logo form) in association with a specific implementation of a Khronos Specification.

Khronos members may use Khronos Marks for promotional and educational purposes according to the terms and conditions in the Khronos Membership Agreement. Members that are not Adopters of a specification are excluded from using a Khronos Mark (in text or logo form) in association with a specific implementation of that Khronos Specification.

Examples:

  • a publisher who wishes to use the OpenCL logo on the cover of a book must apply to Khronos for a Non-Member Trademark License – which grants permission for that specific trademark usage;
  • a Khronos member that is not an Adopter of OpenGL may use the OpenGL logo on a web page that is promoting high performance graphics – as long as no specific implementation of OpenGL is referenced;
  • a Khronos member that is NOT an Adopter of OpenVG may NOT use the OpenVG name OR logo in association with a specific hardware or software implementation of the OpenVG specification.

3. Use of Khronos Marks in Association with a Product Implementation

ANY company using a Khronos Mark (in text or logo form) in association with an implementation of a Khronos specification MUST be a fully paid and signed up Adopter of that specification.

If a product has not fully passed the Khronos Conformance Process an Adopter may NOT use wording associated with that product such as “conformant”, “compliant”, “complies with”, “full implementation” or any other term that implies in any way that the implementation is officially compliant.

3.1 Provisional specification or conformance tests not available

An Adopter with an implementation of a provisional specification, or an implementation of a specification that does not have available conformance tests, may use the relevant Khronos Mark in association with the implementation with the following restrictions:

  1. only in text and not logo form;
  2. any materials using the Khronos Mark must state as appropriate:

    “Product is based on a provisional Khronos Specification, which may change before final release. Current specification status can be found at www.khronos.org/specname

    Or

    “Product is based on a published Khronos Specification, and is expected to pass the Khronos Conformance Testing Process when available. Current conformance status can be found at www.khronos.org/conformance.”

3.2 Products before submission to conformance process

An Adopter with an implementation of a published specification that has not yet been submitted to the Khronos Conformance Process may use the relevant Khronos Mark in association with the implementation with the following restrictions:

  1. only in text and not logo form;
  2. any materials using the Khronos Mark must state:

    “Product is based on a published Khronos Specification, and is expected to pass the Khronos Conformance Testing Process. Current conformance status can be found at www.khronos.org/conformance.”

3.3 Products during Submission Review Period

An Adopter with an implementation of a published specification that has been submitted to the Khronos Conformance Process and is in the Conformance Review Period, including any restarts of the Review Period, may use the relevant Khronos Mark in text and logo form in association with the implementation with the following restriction:

  1. any materials using the Khronos Mark must state:

    “Product is based on a published Khronos Specification, and is expected to pass the Khronos ConformanceTestingProcess. Current conformance status can be found at www.khronos.org/conformance.”

3.4 Conformant Products

An Adopter that has an implementation of a published specification that has been submitted to and passed the Khronos Conformance Process may use the relevant Khronos Mark in text, logo and certification mark form in association with the implementation, and Adopters may state that their products are conformant or compliant with the appropriate specifications with statements similar to:

“Product is conformant with [Khronos Specification]”

“Product is compliant with [Khronos Specification]”

“Product is complies with [Khronos Specification]”

“Product is a full implementation with [Khronos Specification]”.

or use other terms as appropriate that communicates that the implementation is officially compliant.

4. Use of Khronos Marks in Platform Definitions

ANY company using a Khronos Mark (in text or logo form) within a platform or operating system definition that references a Khronos specification MUST be a fully paid and signed up Adopter of that specification.

Adopters may use a Khronos Mark in an operating system specification or platform definition, in text or logo form, provided that Khronos Conformance for products implementing the referenced specifications is mandated as part of the conformance procedure for that platform.

5. Trademark Usage

Any party that is granted use of Khronos Marks must follow Khronos Trademark Usage Guidelines at www.khronos.org/trademarks.

In addition:

Apple has licensed the OpenCL trademark to Khronos, and any use of the OpenCL mark must follow both Apple’s Guidelines for Using Apple Trademarks found at http://www.apple.com/legal/trademark/guidelinesfor3rdparties.html, and any additional OpenCL Logo Guidelines posted by Apple.

SGI has licensed the OpenGL, OpenML, OpenGL ES and OpenGL SC trademarks to Khronos, and any use of the SGI Marks must follow SGI’s guidelines for using SGI trademarks found at http://www.sgi.com/company_info/trademarks.

In case of a discrepancy between this page and the Khronos Group Trademark Guidelines PDF, the PDF shall take precedence.
