# Due Diligence for Submission of Bug Fixes and Patches from Non-Committers

Before committing code from a bug fix or patch provided by a third party who has not signed a current Common Public License to become a Contributor to the project, the IBM committer should ask the following questions and follow up as appropriate in order to ensure that the code can be contributed to the project:

- What is your name and who is your employer?
- Did you write the code that you wish to contribute to the DITA Open Toolkit project? (If the contributor says no, do not submit it as a “Contribution” to the project. You may ask the contributor to identify the complete details of the code’s source and of any licenses or restrictions applicable to the code, but you should conspicuously mark the work as “Submitted on behalf of a third-party: [name of contributor]” when you submit it to the list.)
- Do you have the right to grant the copyright and patent licenses for the contribution that are set forth in the CPL version 1.0 license and Apache License version 2.0?
- Does your employer have any rights to code that you have written, for example, through your contract for employment? If so, has your employer given you permission to contribute the code on its behalf or waived its rights in the code?
- Are you aware of any third-party licenses or other restrictions (such as related patents or trademarks) that could apply to your contribution? If so, what are they?
