IP Policy

The Intellectual Property Policy (“IP Policy”) for the Foundation is as follows:

The prpl Foundation strives to be a royalty-free organization.  Distinction is made between Code and Non-Code documents.  Code refers to source-code and its binary forms.  Non-Code refers to all other prpl documents including, but not limited to, Requirements Analyses, Specifications, Recommendations, API application programming interfaces, and Test Plans.  Participants in Foundation activities and discussions agree to use their true name and corporate affiliation (if any), and be bound by the policies of the Foundation.


Outbound Code Distributions

The Foundation will release code which is developed for any prpl projects (“Project Code”) under the BSD+Patent License ( unless the Board of Directors votes to change the license as provided in the Bylaws. Except as otherwise expressly stated in the BSD+Patent License, the Foundation does not grant any licenses under copyrights, patents or other intellectual property for Project Code.

The Foundation acknowledges that third-party code may be included in prpl projects and that such third-party code may be under other licenses.

The Foundation will maintain on its site a list of all Project Code. Any other code developed and contributed will fall under the Inbound Contributions category.


Inbound Code Contributions

All inbound contributions of code to the Foundation will include a sign off by the developer/contributor of a Developer’s Certificate of Origin (“DCO”) and must comply with the inbound code review policy adopted by the Foundation (as may be updated by the Foundation from time to time). The DCO is the same as used by for Linux and is set forth below.

The contributor must declare under which OSI-approved open source license the contribution is made. Contributions are preferred under the BSD+Patent License. The Maintainer and Chair of a project will decide if a contribution’s license is acceptable. Modifications to already contributed code will be contributed under the same license as the code being modified.

The Foundation will not accept contributions of code under the GPLv3 License (

In addition, all contributions of original code specifically developed for the prpl project and submitted by developer/contributor to the Foundation will be submitted under the BSD+Patent License unless the Board of Directors votes to change the license as provided in the Bylaws. The Foundation acknowledges that third-party code may be included in the prpl project and that such third-party code may be under other licenses.  Note: The BSD+Patent license is not to be confused with a license from Facebook with a similar name (BSD+Patents).  The BSD+Patent license used by prpl is approved by the Open Source Initiative—see


By making a contribution to this project, I certify that:

(a) The contribution was created in whole or in part by me and I have the right to submit it under the open source license indicated in the file; or

(b) The contribution is based upon previous work that, to the best of my knowledge, is covered under an appropriate open source license and I have the right under that license to submit that work with modifications, whether created in whole or in part by me, under the same open source license (unless I am permitted to submit under a different license), as indicated in the file; or

(c) The contribution was provided directly to me by some other person who certified (a), (b) or (c) and I have not modified it.

(d) I understand and agree that this project and the contribution are public and that a record of the contribution (including all personal information I submit with it, including my sign-off) is maintained indefinitely and may be redistributed consistent with this project or the open source license(s) involved.

Then you just add a line saying: Signed-off-by: Jane Doe <[email protected]””> using your real name (no pseudonyms or anonymous contributions permitted).</[email protected]>


Non-Code Contributions

Contributions to prpl activities and discussions are preferred and presumed to be under RAND-Z terms:  fair, reasonable, and non-discriminatory, with zero-royalty.  Contributions may be accepted as RAND, but only after prior submission of a LoA such as described below.  Patent disclosures are welcome and encouraged, on an ongoing basis, and should be submitted to the appropriate working group chair.  Contributions might get modified, or published as is, or be contributed to another standards organization (e.g., The Broadband Forum).

LoA (optional)

Letter of Assurance
This letter assures that, if the submitter (or its affiliates) is a proprietor of essential patent claims that read on a contribution or work item in the prpl Foundation, the submitter agrees to make available a fair, reasonable and non-discriminatory (RAND) license available to adopters and implementers of the contribution or work item, to make, have made, use, sell, offer to sell, or import.  The submitter (and its affliliates) agrees to bind any assignee or transferee to the terms of this LoA.  Affiliates would include both subsidiaries and parents.

Optionally, the submitter can specify:

  1. The patent/application/docket number(s) of the patent(s);
  2. A sample of such a license that is substantially similar to what the submitter would offer; or,
  3. Limitation of scope, if any.

The undersigned has authority to bind the submitter and its affiliates to the commitments of this LoA.
