Contribution License Agreement
2+
3+
This Contribution License Agreement ("Agreement") is agreed to by the party
4+
signing below ("You"), and conveys certain license rights to NVIDIA Corporation
5+
and its affiliates ("NVIDIA") for Your contributions to NVIDIA open source
6+
projects. This Agreement is effective as of the latest signature date below.
7+
8+
1. Definitions.
9+
10+
"Code" means the computer software code, whether in human-readable or
11+
machine-executable form, that is delivered by You to NVIDIA under this
12+
Agreement.
13+
14+
"Project" means any of the projects owned or managed by NVIDIA in which
15+
software is offered under a license approved by the Open Source Initiative
16+
(OSI) (www.opensource.org) and documentation offered under an OSI or a
17+
Creative Commons license (https://creativecommons.org/licenses).
18+
19+
"Submit" is the act of uploading, submitting, transmitting, or distributing
20+
code or other content to any Project, including but not limited to
21+
communication on electronic mailing lists, source code control systems,
22+
and issue tracking systems that are managed by, or on behalf of, the
23+
Project for the purpose of discussing and improving that Project, but
24+
excluding communication that is conspicuously marked or otherwise
25+
designated in writing by You as "Not a Submission."
26+
27+
"Submission" means the Code and any other copyrightable material Submitted
28+
by You, including any associated comments and documentation.
29+
30+
2. Your Submission. You must agree to the terms of this Agreement before
31+
making a Submission to any Project. This Agreement covers any and all
32+
Submissions that You, now or in the future (except as described in Section
33+
4 below), Submit to any Project.
34+
35+
3. Originality of Work. You represent that each of Your Submissions is
36+
entirely Your original work. Should You wish to Submit materials that are
37+
not Your original work, You may Submit them separately to the Project if
38+
You (a) retain all copyright and license information that was in the
39+
materials as You received them, (b) in the description accompanying Your
40+
Submission, include the phrase "Submission containing materials of a
41+
third party:" followed by the names of the third party and any licenses
42+
or other restrictions of which You are aware, and (c) follow any other
43+
instructions in the Project’s written guidelines concerning Submissions.
44+
45+
4. Your Employer. References to "employer" in this Agreement include Your
46+
employer or anyone else for whom You are acting in making Your Submission,
47+
e.g. as a contractor, vendor, or agent. If Your Submission is made in the
48+
course of Your work for an employer or Your employer has intellectual
49+
property rights in Your Submission by contract or applicable law, You must
50+
secure permission from Your employer to make the Submission before signing
51+
this Agreement. In that case, the term "You" in this Agreement will refer
52+
to You and the employer collectively. If You change employers in the
53+
future and desire to Submit additional Submissions for the new employer,
54+
then You agree to sign a new Agreement and secure permission from the
55+
new employer before Submitting those Submissions.
56+
57+
5. Licenses.
58+
59+
a. Copyright License. You grant NVIDIA, and those who receive the Submission
60+
directly or indirectly from NVIDIA, a perpetual, worldwide, non-exclusive,
61+
royalty-free, irrevocable license in the Submission to reproduce, prepare
62+
derivative works of, publicly display, publicly perform, and distribute the
63+
Submission and such derivative works, and to sublicense any or all of the
64+
foregoing rights to third parties.
65+
66+
b. Patent License. You grant NVIDIA, and those who receive the Submission
67+
directly or indirectly from NVIDIA, a perpetual, worldwide, non-exclusive,
68+
royalty-free, irrevocable license under Your patent claims that are
69+
necessarily infringed by the Submission or the combination of the Submission
70+
with the Project to which it was Submitted to make, have made, use, offer to
71+
sell, sell and import or otherwise dispose of the Submission alone or with
72+
the Project.
73+
74+
c. Other Rights Reserved. Each party reserves all rights not expressly
75+
granted in this Agreement. No additional licenses or rights whatsoever
76+
(including, without limitation, any implied licenses) are granted by
77+
implication, exhaustion, estoppel or otherwise.
78+
79+
6. Representations and Warranties. You represent that You are legally
80+
entitled to grant the above licenses. You represent that each of Your
81+
Submissions is entirely Your original work (except as You may have
82+
disclosed under Section 3). You represent that You have secured permission
83+
from Your employer to make the Submission in cases where Your Submission
84+
is made in the course of Your work for Your employer or Your employer has
85+
intellectual property rights in Your Submission by contract or applicable
86+
law. If You are signing this Agreement on behalf of Your employer, You
87+
represent and warrant that You have the necessary authority to bind the
88+
listed employer to the obligations contained in this Agreement. You are
89+
not expected to provide support for Your Submission, unless You choose to
90+
do so. UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING, AND
91+
EXCEPT FOR THE WARRANTIES EXPRESSLY STATED IN SECTIONS 3, 4, AND 6, THE
92+
SUBMISSION PROVIDED UNDER THIS AGREEMENT IS PROVIDED WITHOUT WARRANTY OF
93+
ANY KIND, INCLUDING, BUT NOT LIMITED TO, ANY WARRANTY OF NONINFRINGEMENT,
94+
MERCHANTABILITY, OR FITNESS FOR A PARTICULAR PURPOSE.
95+
96+
7. Notice to NVIDIA. You agree to notify NVIDIA in writing of any facts
97+
or circumstances of which You later become aware that would make Your
98+
representations in this Agreement inaccurate in any respect.
99+
100+
8. Information about Submissions. You agree that contributions to Projects
101+
and information about contributions may be maintained indefinitely and
102+
disclosed publicly, including Your name and other information that You
103+
submit with Your Submission.
104+
105+
9. Governing Law/Jurisdiction. Claims arising under this Agreement shall
106+
be governed by the laws of Delaware, excluding its principles of conflict
107+
of laws and the United Nations Convention on Contracts for the Sale of
108+
Goods. The state and/or federal courts residing in Santa Clara County,
109+
California shall have exclusive jurisdiction over any dispute or claim
110+
arising out of this Agreement. You may not export the Software in
111+
violation of applicable export laws and regulations.
112+
113+
10. Entire Agreement/Assignment. This Agreement is the entire agreement
114+
between the parties, and supersedes any and all prior agreements,
115+
understandings or communications, written or oral, between the parties
116+
relating to the subject matter hereof. This Agreement may be assigned by
117+
NVIDIA.
118+

Please select one of the options below and sign as indicated. By signing,
122+
You accept and agree to the terms of this Contribution License Agreement
123+
for Your present and future Submissions to NVIDIA.
