BitTorrent Open Source License
|
|
|
|
Version 1.0
|
|
|
|
This BitTorrent Open Source License (the "License") applies to the BitTorrent
|
|
client and related software products as well as any updates or maintenance
|
|
releases of that software ("BitTorrent Products") that are distributed by
|
|
BitTorrent, Inc. ("Licensor"). Any BitTorrent Product licensed pursuant to
|
|
this License is a Licensed Product. Licensed Product, in its entirety, is
|
|
protected by U.S. copyright law. This License identifies the terms under which
|
|
you may use, copy, distribute or modify Licensed Product.
|
|
|
|
Preamble
|
|
|
|
This Preamble is intended to describe, in plain English, the nature and scope
|
|
of this License. However, this Preamble is not a part of this license. The
|
|
legal effect of this License is dependent only upon the terms of the License
|
|
and not this Preamble.
|
|
|
|
This License complies with the Open Source Definition and is derived from
|
|
the Jabber Open Source License 1.0 (the "JOSL"), which has been approved by
|
|
Open Source Initiative. Sections 4(c) and 4(f)(iii) from the JOSL have been
|
|
dropped.
|
|
|
|
This License provides that:
|
|
|
|
1. You may use, sell or give away the Licensed Product, alone or as a component
|
|
of an aggregate software distribution containing programs from several different
|
|
sources. No royalty or other fee is required.
|
|
|
|
2. Both Source Code and executable versions of the Licensed Product, including
|
|
Modifications made by previous Contributors, are available for your use. (The
|
|
terms "Licensed Product," "Modifications," "Contributors" and "Source Code"
|
|
are defined in the License.)
|
|
|
|
3. You are allowed to make Modifications to the Licensed Product, and you
|
|
can create Derivative Works from it. (The term "Derivative Works" is defined
|
|
in the License.)
|
|
|
|
4. By accepting the Licensed Product under the provisions of this License,
|
|
you agree that any Modifications you make to the Licensed Product and then
|
|
distribute are governed by the provisions of this License. In particular,
|
|
you must make the Source Code of your Modifications available to others.
|
|
|
|
5. You may use the Licensed Product for any purpose, but the Licensor is not
|
|
providing you any warranty whatsoever, nor is the Licensor accepting any liability
|
|
in the event that the Licensed Product doesn't work properly or causes you
|
|
any injury or damages.
|
|
|
|
6. If you sublicense the Licensed Product or Derivative Works, you may charge
|
|
fees for warranty or support, or for accepting indemnity or liability obligations
|
|
to your customers. You cannot charge for the Source Code.
|
|
|
|
7. If you assert any patent claims against the Licensor relating to the Licensed
|
|
Product, or if you breach any terms of the License, your rights to the Licensed
|
|
Product under this License automatically terminate.
|
|
|
|
You may use this License to distribute your own Derivative Works, in which
|
|
case the provisions of this License will apply to your Derivative Works just
|
|
as they do to the original Licensed Product.
|
|
|
|
Alternatively, you may distribute your Derivative Works under any other OSI-approved
|
|
Open Source license, or under a proprietary license of your choice. If you
|
|
use any license other than this License, however, you must continue to fulfill
|
|
the requirements of this License (including the provisions relating to publishing
|
|
the Source Code) for those portions of your Derivative Works that consist
|
|
of the Licensed Product, including the files containing Modifications.
|
|
|
|
New versions of this License may be published from time to time. You may choose
|
|
to continue to use the license terms in this version of the License or those
|
|
from the new version. However, only the Licensor has the right to change the
|
|
License terms as they apply to the Licensed Product.
|
|
|
|
This License relies on precise definitions for certain terms. Those terms
|
|
are defined when they are first used, and the definitions are repeated for
|
|
your convenience in a Glossary at the end of the License.
|
|
|
|
License Terms
|
|
|
|
1. Grant of License From Licensor. Licensor hereby grants you a world-wide,
|
|
royalty-free, non-exclusive license, subject to third party intellectual property
|
|
claims, to do the following:
|
|
|
|
a. Use, reproduce, modify, display, perform, sublicense and distribute any
|
|
Modifications created by such Contributor or portions thereof, in both Source
|
|
Code or as an executable program, either on an unmodified basis or as part
|
|
of Derivative Works.
|
|
|
|
b. Under claims of patents now or hereafter owned or controlled by Contributor,
|
|
to make, use, sell, offer for sale, have made, and/or otherwise dispose of
|
|
Modifications or portions thereof, but solely to the extent that any such
|
|
claim is necessary to enable you to make, use, sell, offer for sale, have
|
|
made, and/or otherwise dispose of Modifications or portions thereof or Derivative
|
|
Works thereof.
|
|
|
|
2. Grant of License to Modifications From Contributor. "Modifications" means
|
|
any additions to or deletions from the substance or structure of (i) a file
|
|
containing Licensed Product, or (ii) any new file that contains any part of
|
|
Licensed Product. Hereinafter in this License, the term "Licensed Product"
|
|
shall include all previous Modifications that you receive from any Contributor.
|
|
By application of the provisions in Section 4(a) below, each person or entity
|
|
who created or contributed to the creation of, and distributed, a Modification
|
|
(a "Contributor") hereby grants you a world-wide, royalty-free, non-exclusive
|
|
license, subject to third party intellectual property claims, to do the following:
|
|
|
|
a. Use, reproduce, modify, display, perform, sublicense and distribute any
|
|
Modifications created by such Contributor or portions thereof, in both Source
|
|
Code or as an executable program, either on an unmodified basis or as part
|
|
of Derivative Works.
|
|
|
|
b. Under claims of patents now or hereafter owned or controlled by Contributor,
|
|
to make, use, sell, offer for sale, have made, and/or otherwise dispose of
|
|
Modifications or portions thereof, but solely to the extent that any such
|
|
claim is necessary to enable you to make, use, sell, offer for sale, have
|
|
made, and/or otherwise dispose of Modifications or portions thereof or Derivative
|
|
Works thereof.
|
|
|
|
3. Exclusions From License Grant. Nothing in this License shall be deemed
|
|
to grant any rights to trademarks, copyrights, patents, trade secrets or any
|
|
other intellectual property of Licensor or any Contributor except as expressly
|
|
stated herein. No patent license is granted separate from the Licensed Product,
|
|
for code that you delete from the Licensed Product, or for combinations of
|
|
the Licensed Product with other software or hardware. No right is granted
|
|
to the trademarks of Licensor or any Contributor even if such marks are included
|
|
in the Licensed Product. Nothing in this License shall be interpreted to prohibit
|
|
Licensor from licensing under different terms from this License any code that
|
|
Licensor otherwise would have a right to license.
|
|
|
|
4. Your Obligations Regarding Distribution.
|
|
|
|
a. Application of This License to Your Modifications. As an express condition
|
|
for your use of the Licensed Product, you hereby agree that any Modifications
|
|
that you create or to which you contribute, and which you distribute, are
|
|
governed by the terms of this License including, without limitation, Section
|
|
2. Any Modifications that you create or to which you contribute may be distributed
|
|
only under the terms of this License or a future version of this License released
|
|
under Section 7. You must include a copy of this License with every copy of
|
|
the Modifications you distribute. You agree not to offer or impose any terms
|
|
on any Source Code or executable version of the Licensed Product or Modifications
|
|
that alter or restrict the applicable version of this License or the recipients'
|
|
rights hereunder. However, you may include an additional document offering
|
|
the additional rights described in Section 4(d).
|
|
|
|
b. Availability of Source Code. You must make available, under the terms of
|
|
this License, the Source Code of the Licensed Product and any Modifications
|
|
that you distribute, either on the same media as you distribute any executable
|
|
or other form of the Licensed Product, or via a mechanism generally accepted
|
|
in the software development community for the electronic transfer of data
|
|
(an "Electronic Distribution Mechanism"). The Source Code for any version
|
|
of Licensed Product or Modifications that you distribute must remain available
|
|
for at least twelve (12) months after the date it initially became available,
|
|
or at least six (6) months after a subsequent version of said Licensed Product
|
|
or Modifications has been made available. You are responsible for ensuring
|
|
that the Source Code version remains available even if the Electronic Distribution
|
|
Mechanism is maintained by a third party.
|
|
|
|
c. Intellectual Property Matters.
|
|
|
|
i. Third Party Claims. If you have knowledge that a license to a third party's
|
|
intellectual property right is required to exercise the rights granted by
|
|
this License, you must include a text file with the Source Code distribution
|
|
titled "LEGAL" that describes the claim and the party making the claim in
|
|
sufficient detail that a recipient will know whom to contact. If you obtain
|
|
such knowledge after you make any Modifications available as described in
|
|
Section 4(b), you shall promptly modify the LEGAL file in all copies you make
|
|
available thereafter and shall take other steps (such as notifying appropriate
|
|
mailing lists or newsgroups) reasonably calculated to inform those who received
|
|
the Licensed Product from you that new knowledge has been obtained.
|
|
|
|
ii. Contributor APIs. If your Modifications include an application programming
|
|
interface ("API") and you have knowledge of patent licenses that are reasonably
|
|
necessary to implement that API, you must also include this information in
|
|
the LEGAL file.
|
|
|
|
iii. Representations. You represent that, except as disclosed pursuant to
|
|
4(c)(i) above, you believe that any Modifications you distribute are your
|
|
original creations and that you have sufficient rights to grant the rights
|
|
conveyed by this License.
|
|
|
|
d. Required Notices. You must duplicate this License in any documentation
|
|
you provide along with the Source Code of any Modifications you create or
|
|
to which you contribute, and which you distribute, wherever you describe recipients'
|
|
rights relating to Licensed Product. You must duplicate the notice contained
|
|
in Exhibit A (the "Notice") in each file of the Source Code of any copy you
|
|
distribute of the Licensed Product. If you created a Modification, you may
|
|
add your name as a Contributor to the Notice. If it is not possible to put
|
|
the Notice in a particular Source Code file due to its structure, then you
|
|
must include such Notice in a location (such as a relevant directory file)
|
|
where a user would be likely to look for such a notice. You may choose to
|
|
offer, and charge a fee for, warranty, support, indemnity or liability obligations
|
|
to one or more recipients of Licensed Product. However, you may do so only
|
|
on your own behalf, and not on behalf of the Licensor or any Contributor.
|
|
You must make it clear that any such warranty, support, indemnity or liability
|
|
obligation is offered by you alone, and you hereby agree to indemnify the
|
|
Licensor and every Contributor for any liability incurred by the Licensor
|
|
or such Contributor as a result of warranty, support, indemnity or liability
|
|
terms you offer.
|
|
|
|
e. Distribution of Executable Versions. You may distribute Licensed Product
|
|
as an executable program under a license of your choice that may contain terms
|
|
different from this License provided (i) you have satisfied the requirements
|
|
of Sections 4(a) through 4(d) for that distribution, (ii) you include a conspicuous
|
|
notice in the executable version, related documentation and collateral materials
|
|
stating that the Source Code version of the Licensed Product is available
|
|
under the terms of this License, including a description of how and where
|
|
you have fulfilled the obligations of Section 4(b), and (iii) you make it
|
|
clear that any terms that differ from this License are offered by you alone,
|
|
not by Licensor or any Contributor. You hereby agree to indemnify the Licensor
|
|
and every Contributor for any liability incurred by Licensor or such Contributor
|
|
as a result of any terms you offer.
|
|
|
|
f. Distribution of Derivative Works. You may create Derivative Works (e.g.,
|
|
combinations of some or all of the Licensed Product with other code) and distribute
|
|
the Derivative Works as products under any other license you select, with
|
|
the proviso that the requirements of this License are fulfilled for those
|
|
portions of the Derivative Works that consist of the Licensed Product or any
|
|
Modifications thereto.
|
|
|
|
5. Inability to Comply Due to Statute or Regulation. If it is impossible for
|
|
you to comply with any of the terms of this License with respect to some or
|
|
all of the Licensed Product due to statute, judicial order, or regulation,
|
|
then you must (i) comply with the terms of this License to the maximum extent
|
|
possible, (ii) cite the statute or regulation that prohibits you from adhering
|
|
to the License, and (iii) describe the limitations and the code they affect.
|
|
Such description must be included in the LEGAL file described in Section 4(d),
|
|
and must be included with all distributions of the Source Code. Except to
|
|
the extent prohibited by statute or regulation, such description must be sufficiently
|
|
detailed for a recipient of ordinary skill at computer programming to be able
|
|
to understand it.
|
|
|
|
6. Application of This License. This License applies to code to which Licensor
|
|
or Contributor has attached the Notice in Exhibit A, which is incorporated
|
|
herein by this reference.
|
|
|
|
7. Versions of This License.
|
|
|
|
a. New Versions. Licensor may publish from time to time revised and/or new
|
|
versions of the License.
|
|
|
|
b. Effect of New Versions. Once Licensed Product has been published under
|
|
a particular version of the License, you may always continue to use it under
|
|
the terms of that version. You may also choose to use such Licensed Product
|
|
under the terms of any subsequent version of the License published by Licensor.
|
|
No one other than Licensor has the right to modify the terms applicable to
|
|
Licensed Product created under this License.
|
|
|
|
c. Derivative Works of this License. If you create or use a modified version
|
|
of this License, which you may do only in order to apply it to software that
|
|
is not already a Licensed Product under this License, you must rename your
|
|
license so that it is not confusingly similar to this License, and must make
|
|
it clear that your license contains terms that differ from this License. In
|
|
so naming your license, you may not use any trademark of Licensor or any Contributor.
|
|
|
|
8. Disclaimer of Warranty. LICENSED PRODUCT IS PROVIDED UNDER THIS LICENSE
|
|
ON AN AS IS BASIS, WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESS OR IMPLIED,
|
|
INCLUDING, WITHOUT LIMITATION, WARRANTIES THAT THE LICENSED PRODUCT IS FREE
|
|
OF DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING.
|
|
THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LICENSED PRODUCT
|
|
IS WITH YOU. SHOULD LICENSED PRODUCT PROVE DEFECTIVE IN ANY RESPECT, YOU (AND
|
|
NOT THE LICENSOR OR ANY OTHER CONTRIBUTOR) ASSUME THE COST OF ANY NECESSARY
|
|
SERVICING, REPAIR OR CORRECTION. THIS DISCLAIMER OF WARRANTY CONSTITUTES AN
|
|
ESSENTIAL PART OF THIS LICENSE. NO USE OF LICENSED PRODUCT IS AUTHORIZED HEREUNDER
|
|
EXCEPT UNDER THIS DISCLAIMER.
|
|
|
|
9. Termination.
|
|
|
|
a. Automatic Termination Upon Breach. This license and the rights granted
|
|
hereunder will terminate automatically if you fail to comply with the terms
|
|
herein and fail to cure such breach within thirty (30) days of becoming aware
|
|
of the breach. All sublicenses to the Licensed Product that are properly granted
|
|
shall survive any termination of this license. Provisions that, by their nature,
|
|
must remain in effect beyond the termination of this License, shall survive.
|
|
|
|
b. Termination Upon Assertion of Patent Infringement. If you initiate litigation
|
|
by asserting a patent infringement claim (excluding declaratory judgment actions)
|
|
against Licensor or a Contributor (Licensor or Contributor against whom you
|
|
file such an action is referred to herein as Respondent) alleging that Licensed
|
|
Product directly or indirectly infringes any patent, then any and all rights
|
|
granted by such Respondent to you under Sections 1 or 2 of this License shall
|
|
terminate prospectively upon sixty (60) days notice from Respondent (the "Notice
|
|
Period") unless within that Notice Period you either agree in writing (i)
|
|
to pay Respondent a mutually agreeable reasonably royalty for your past or
|
|
future use of Licensed Product made by such Respondent, or (ii) withdraw your
|
|
litigation claim with respect to Licensed Product against such Respondent.
|
|
If within said Notice Period a reasonable royalty and payment arrangement
|
|
are not mutually agreed upon in writing by the parties or the litigation claim
|
|
is not withdrawn, the rights granted by Licensor to you under Sections 1 and
|
|
2 automatically terminate at the expiration of said Notice Period.
|
|
|
|
c. Reasonable Value of This License. If you assert a patent infringement claim
|
|
against Respondent alleging that Licensed Product directly or indirectly infringes
|
|
any patent where such claim is resolved (such as by license or settlement)
|
|
prior to the initiation of patent infringement litigation, then the reasonable
|
|
value of the licenses granted by said Respondent under Sections 1 and 2 shall
|
|
be taken into account in determining the amount or value of any payment or
|
|
license.
|
|
|
|
d. No Retroactive Effect of Termination. In the event of termination under
|
|
Sections 9(a) or 9(b) above, all end user license agreements (excluding licenses
|
|
to distributors and resellers) that have been validly granted by you or any
|
|
distributor hereunder prior to termination shall survive termination.
|
|
|
|
10. Limitation of Liability. UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY,
|
|
WHETHER TORT (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL THE LICENSOR,
|
|
ANY CONTRIBUTOR, OR ANY DISTRIBUTOR OF LICENSED PRODUCT, OR ANY SUPPLIER OF
|
|
ANY OF SUCH PARTIES, BE LIABLE TO ANY PERSON FOR ANY INDIRECT, SPECIAL, INCIDENTAL,
|
|
OR CONSEQUENTIAL DAMAGES OF ANY CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES
|
|
FOR LOSS OF GOODWILL, WORK STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY
|
|
AND ALL OTHER COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE
|
|
BEEN INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF LIABILITY
|
|
SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY
|
|
|
|
RESULTING FROM SUCH PARTYS NEGLIGENCE TO THE EXTENT APPLICABLE LAW PROHIBITS
|
|
SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION
|
|
OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS EXCLUSION AND LIMITATION MAY
|
|
NOT APPLY TO YOU.
|
|
|
|
11. Responsibility for Claims. As between Licensor and Contributors, each
|
|
party is responsible for claims and damages arising, directly or indirectly,
|
|
out of its utilization of rights under this License. You agree to work with
|
|
Licensor and Contributors to distribute such responsibility on an equitable
|
|
basis. Nothing herein is intended or
|
|
|
|
shall be deemed to constitute any admission of liability.
|
|
|
|
12. U.S. Government End Users. The Licensed Product is a commercial item,
|
|
as that term is defined in 48 C.F.R. 2.101 (Oct. 1995), consisting of commercial
|
|
computer software and commercial computer software documentation, as such
|
|
terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent with 48 C.F.R.
|
|
12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995), all U.S. Government
|
|
End Users acquire Licensed Product with only those rights set forth herein.
|
|
|
|
13. Miscellaneous. This License represents the complete agreement concerning
|
|
the subject matter hereof. If any provision of this License is held to be
|
|
unenforceable, such provision shall be reformed only to the extent necessary
|
|
to make it enforceable. This License shall be governed by California law provisions
|
|
(except to the extent applicable law, if any, provides otherwise), excluding
|
|
its conflict-of-law provisions. You expressly agree that any litigation relating
|
|
to this license shall be subject to the jurisdiction of the Federal Courts
|
|
of the Northern District of California or the Superior Court of the County
|
|
of Santa Clara, California (as appropriate), with venue lying in Santa Clara
|
|
County, California, with the losing party responsible for costs including,
|
|
without limitation, court costs and reasonable attorneys fees and expenses.
|
|
The application of the United Nations Convention on Contracts for the International
|
|
Sale of Goods is expressly excluded. You and Licensor expressly waive any
|
|
rights to a jury trial in any litigation concerning Licensed Product or this
|
|
License. Any law or regulation that provides that the language of a contract
|
|
shall be construed against the drafter shall not apply to this License.
|
|
|
|
14. Definition of You in This License. You throughout this License, whether
|
|
in upper or lower case, means an individual or a legal entity exercising rights
|
|
under, and complying with all of the terms of, this License or a future version
|
|
of this License issued under Section 7. For legal entities, you includes any
|
|
entity that controls, is controlled by, or is under common control with you.
|
|
For purposes of this definition, control means (i) the power, direct or indirect,
|
|
to cause the direction or management of such entity, whether by contract or
|
|
otherwise, or (ii) ownership of fifty percent (50%) or more of the outstanding
|
|
shares, or (iii) beneficial ownership of such entity.
|
|
|
|

|
|
