Copyrights for Documents, Software, Tests

W3C offers several licenses depending on the nature of the material, and whether derivative works are permitted.

• The Document License governs documents such as technical reports. See also the policy for relicensing unfinished W3C specifications
• The Software License governs distribution of W3C W3C Open Source Software and some other materials where creation of derivative works may be desired.
• The Test Suite Licenses governs the distribution of W3C test suites. There are two licenses, depending on whether you plan to modify the test cases. W3C encourages people to contribute to W3C test suites; contributors agree to the Test Case Contribution Policy.
• In Community and Business Groups, draft Specifications are governed by a W3C Community Contributor License Agreement (CLA). Participants then sign (voluntarily) a Final Specification Agreement. These agreements include both copyright and patent licensing provisions.

Trademarks

W3C trademarks and logos are governed by the trademark license. There are also some additional usage policies for some logos, such as the W3C logo usage policies.

Patent Policy

In February 2004, W3C adopted a Patent Policy to enable continued innovation and widespread adoption of Web standards developed by the World Wide Web Consortium. The W3C Patent Policy governs the handling of patents in the process of producing Web Standards. The goal of this policy is to assure that Recommendations produced under this policy can be implemented on a Royalty-Free (RF) basis. See the Patent Policy FAQ for additional information.
