# Ultralytics Individual Contributor License Agreement

Thank you for your interest in contributing to open source software projects (“Projects”) made available by Ultralytics
SE or its affiliates (“Ultralytics”). This Individual Contributor License Agreement (“Agreement”) sets out the terms
governing any source code, object code, bug fixes, configuration changes, tools, specifications, documentation, data,
materials, feedback, information or other works of authorship that you submit or have submitted, in any form and in any
manner, to Ultralytics in respect of any of the Projects (collectively “Contributions”). If you have any questions
respecting this Agreement, please contact hello@ultralytics.com.

You agree that the following terms apply to all of your past, present and future Contributions. Except for the licenses
granted in this Agreement, you retain all of your right, title and interest in and to your Contributions.

**Copyright License.** You hereby grant, and agree to grant, to Ultralytics a non-exclusive, perpetual, irrevocable,
worldwide, fully-paid, royalty-free, transferable copyright license to reproduce, prepare derivative works of, publicly
display, publicly perform, and distribute your Contributions and such derivative works, with the right to sublicense the
foregoing rights through multiple tiers of sublicensees.

**Patent License.** You hereby grant, and agree to grant, to Ultralytics a non-exclusive, perpetual, irrevocable,
worldwide, fully-paid, royalty-free, transferable patent license to make, have made, use, offer to sell, sell,
import, and otherwise transfer your Contributions, where such license applies only to those patent claims
licensable by you that are necessarily infringed by your Contributions alone or by combination of your
Contributions with the Project to which such Contributions were submitted, with the right to sublicense the
foregoing rights through multiple tiers of sublicensees.

**Moral Rights.** To the fullest extent permitted under applicable law, you hereby waive, and agree not to
assert, all of your “moral rights” in or relating to your Contributions for the benefit of Ultralytics, its assigns, and
their respective direct and indirect sublicensees.

other works of authorship that were not authored by you (“Third Party Content”) or if you are aware of any
third party intellectual property or proprietary rights associated with your Contribution (“Third Party Rights”),

Content and Third Party Rights, including, without limitation, identification of which aspects of your
Contribution contain Third Party Content or are associated with Third Party Rights, the owner/author of the
Third Party Content and Third Party Rights, where you obtained the Third Party Content, and any applicable
third party license terms or restrictions respecting the Third Party Content and Third Party Rights. For greater

do not apply to any portion of a Project that is incorporated into your Contribution to that same Project.

**Representations.** You represent that, other than the Third Party Content and Third Party Rights identified by
you in accordance with this Agreement, you are the sole author of your Contributions and are legally entitled
to grant the foregoing licenses and waivers in respect of your Contributions. If your Contributions were
created in the course of your employment with your past or present employer(s), you represent that such
employer(s) has authorized you to make your Contributions on behalf of such employer(s) or such employer
(s) has waived all of their right, title or interest in or to your Contributions.

basis, without any warranties or conditions, express or implied, including, without limitation, any implied
warranties or conditions of non-infringement, merchantability or fitness for a particular purpose. You are not
required to provide support for your Contributions, except to the extent you desire to provide support.

**No Obligation.** You acknowledge that Ultralytics is under no obligation to use or incorporate your Contributions
into any of the Projects. The decision to use or incorporate your Contributions into any of the Projects will be
made at the sole discretion of Ultralytics or its authorized delegates ..

other than such principles directing application of New York law. The parties hereby submit to venue in, and
jurisdiction of the courts located in New York, New York for purposes relating to this Agreement. In the event
that any of the provisions of this Agreement shall be held by a court or other tribunal of competent jurisdiction
to be unenforceable, the remaining portions hereof shall remain in full force and effect.
