1r#"BitTorrent Open Source License 2 3Version 1.0 4 5This BitTorrent Open Source License (the "License") applies to the BitTorrent client and related software products as 6well as any updates or maintenance releases of that software ("BitTorrent Products") that are distributed by 7BitTorrent, Inc. ("Licensor"). Any BitTorrent Product licensed pursuant to this License is a Licensed Product. 8Licensed Product, in its entirety, is protected by U.S. copyright law. This License identifies the terms under which 9you may use, copy, distribute or modify Licensed Product. 10 11Preamble 12 13This Preamble is intended to describe, in plain English, the nature and scope of this License. However, this 14Preamble is not a part of this license. The legal effect of this License is dependent only upon the terms of the 15License and not this Preamble. 16 17This License complies with the Open Source Definition and is derived from the Jabber Open Source License 1.0 (the 18"JOSL"), which has been approved by Open Source Initiative. Sections 4(c) and 4(f)(iii) from the JOSL have been 19dropped. 20 21This License provides that: 22 231. You may use, sell or give away the Licensed Product, alone or as a component of an aggregate software 24distribution containing programs from several different sources. No royalty or other fee is required. 25 262. Both Source Code and executable versions of the Licensed Product, including Modifications made by previous 27Contributors, are available for your use. (The terms "Licensed Product," "Modifications," "Contributors" and "Source 28Code" are defined in the License.) 29 303. You are allowed to make Modifications to the Licensed Product, and you can create Derivative Works from it. 31(The term "Derivative Works" is defined in the License.) 32 334. By accepting the Licensed Product under the provisions of this License, you agree that any Modifications you 34make to the Licensed Product and then distribute are governed by the provisions of this License. In particular, you 35must make the Source Code of your Modifications available to others. 36 375. You may use the Licensed Product for any purpose, but the Licensor is not providing you any warranty 38whatsoever, nor is the Licensor accepting any liability in the event that the Licensed Product doesn't work properly 39or causes you any injury or damages. 40 416. If you sublicense the Licensed Product or Derivative Works, you may charge fees for warranty or support, or 42for accepting indemnity or liability obligations to your customers. You cannot charge for the Source Code. 43 447. If you assert any patent claims against the Licensor relating to the Licensed Product, or if you breach any 45terms of the License, your rights to the Licensed Product under this License automatically terminate. 46 47You may use this License to distribute your own Derivative Works, in which case the provisions of this License will 48apply to your Derivative Works just as they do to the original Licensed Product. 49 50Alternatively, you may distribute your Derivative Works under any other OSI-approved Open Source license, or under a 51proprietary license of your choice. If you use any license other than this License, however, you must continue to 52fulfill the requirements of this License (including the provisions relating to publishing the Source Code) for those 53portions of your Derivative Works that consist of the Licensed Product, including the files containing Modifications. 54 55New versions of this License may be published from time to time. You may choose to continue to use the license 56terms in this version of the License or those from the new version. However, only the Licensor has the right to 57change the License terms as they apply to the Licensed Product. 58 59This License relies on precise definitions for certain terms. Those terms are defined when they are first used, and 60the definitions are repeated for your convenience in a Glossary at the end of the License. 61 62 63License Terms 64 651. Grant of License From Licensor. Licensor hereby grants you a world-wide, royalty-free, non-exclusive 66license, subject to third party intellectual property claims, to do the following: 67 68a. Use, reproduce, modify, display, perform, sublicense and distribute any Modifications created by such 69Contributor or portions thereof, in both Source Code or as an executable program, either on an unmodified basis or as 70part of Derivative Works. 71 72b. Under claims of patents now or hereafter owned or controlled by Contributor, to make, use, sell, offer for 73sale, have made, and/or otherwise dispose of Modifications or portions thereof, but solely to the extent that any 74such claim is necessary to enable you to make, use, sell, offer for sale, have made, and/or otherwise dispose of 75Modifications or portions thereof or Derivative Works thereof. 76 77 782. Grant of License to Modifications From Contributor. "Modifications" means any additions to or deletions from the 79substance or structure of (i) a file containing Licensed Product, or (ii) any new file that contains any part of 80Licensed Product. Hereinafter in this License, the term "Licensed Product" shall include all previous Modifications 81that you receive from any Contributor. By application of the provisions in Section 4(a) below, each person or entity 82who created or contributed to the creation of, and distributed, a Modification (a "Contributor") hereby grants you a 83world-wide, royalty-free, non-exclusive license, subject to third party intellectual property claims, to do the 84following: 85 86 1. Use, reproduce, modify, display, perform, sublicense and distribute any Modifications created by such 87Contributor or portions thereof, in both Source Code or as an executable program, either on an unmodified basis or as 88part of Derivative Works. 89 90 2. Under claims of patents now or hereafter owned or controlled by Contributor, to make, use, sell, offer for 91sale, have made, and/or otherwise dispose of Modifications or portions thereof, but solely to the extent that any 92such claim is necessary to enable you to make, use, sell, offer for sale, have made, and/or otherwise dispose of 93Modifications or portions thereof or Derivative Works thereof. 94 95 963. Exclusions From License Grant. Nothing in this License shall be deemed to grant any rights to trademarks, 97copyrights, patents, trade secrets or any other intellectual property of Licensor or any Contributor except as 98expressly stated herein. No patent license is granted separate from the Licensed Product, for code that you delete 99from the Licensed Product, or for combinations of the Licensed Product with other software or hardware. No right is 100granted to the trademarks of Licensor or any Contributor even if such marks are included in the Licensed Product. 101Nothing in this License shall be interpreted to prohibit Licensor from licensing under different terms from this 102License any code that Licensor otherwise would have a right to license. 103 104 1054. Your Obligations Regarding Distribution. 106 107a. Application of This License to Your Modifications. As an express condition for your use of the Licensed 108Product, you hereby agree that any Modifications that you create or to which you contribute, and which you 109distribute, are governed by the terms of this License including, without limitation, Section 2. Any Modifications 110that you create or to which you contribute may be distributed only under the terms of this License or a future 111version of this License released under Section 7. You must include a copy of this License with every copy of the 112Modifications you distribute. You agree not to offer or impose any terms on any Source Code or executable version of 113the Licensed Product or Modifications that alter or restrict the applicable version of this License or the 114recipients' rights hereunder. However, you may include an additional document offering the additional rights 115described in Section 4(d). 116 117b. Availability of Source Code. You must make available, under the terms of this License, the Source Code of 118the Licensed Product and any Modifications that you distribute, either on the same media as you distribute any 119executable or other form of the Licensed Product, or via a mechanism generally accepted in the software development 120community for the electronic transfer of data (an "Electronic Distribution Mechanism"). The Source Code for any 121version of Licensed Product or Modifications that you distribute must remain available for at least twelve (12) 122months after the date it initially became available, or at least six (6) months after a subsequent version of said 123Licensed Product or Modifications has been made available. You are responsible for ensuring that the Source Code 124version remains available even if the Electronic Distribution Mechanism is maintained by a third party. 125 126c. Intellectual Property Matters. 127 128 i. Third Party Claims. If you have knowledge that a license to a third 129party's intellectual property right is required to exercise the rights granted by this License, you must include a 130text file with the Source Code distribution titled "LEGAL" that describes the claim and the party making the claim in 131sufficient detail that a recipient will know whom to contact. If you obtain such knowledge after you make any 132Modifications available as described in Section 4(b), you shall promptly modify the LEGAL file in all copies you make 133available thereafter and shall take other steps (such as notifying appropriate mailing lists or newsgroups) 134reasonably calculated to inform those who received the Licensed Product from you that new knowledge has been 135obtained. 136 137 ii. Contributor APIs. If your Modifications include an application 138programming interface ("API") and you have knowledge of patent licenses that are reasonably necessary to implement 139that API, you must also include this information in the LEGAL file. 140 141 iii. Representations. You represent that, except as disclosed pursuant to 1424(c)(i) above, you believe that any Modifications you distribute are your original creations and that you have 143sufficient rights to grant the rights conveyed by this License. 144 145d. Required Notices. You must duplicate this License in any documentation you provide along with the Source 146Code of any Modifications you create or to which you contribute, and which you distribute, wherever you describe 147recipients' rights relating to Licensed Product. You must duplicate the notice contained in Exhibit A (the "Notice") 148in each file of the Source Code of any copy you distribute of the Licensed Product. If you created a Modification, 149you may add your name as a Contributor to the Notice. If it is not possible to put the Notice in a particular Source 150Code file due to its structure, then you must include such Notice in a location (such as a relevant directory file) 151where a user would be likely to look for such a notice. You may choose to offer, and charge a fee for, warranty, 152support, indemnity or liability obligations to one or more recipients of Licensed Product. However, you may do so 153only on your own behalf, and not on behalf of the Licensor or any Contributor. You must make it clear that any such 154warranty, support, indemnity or liability obligation is offered by you alone, and you hereby agree to indemnify the 155Licensor and every Contributor for any liability incurred by the Licensor or such Contributor as a result of 156warranty, support, indemnity or liability terms you offer. 157 158e. Distribution of Executable Versions. You may distribute Licensed Product as an executable program under a 159license of your choice that may contain terms different from this License provided (i) you have satisfied the 160requirements of Sections 4(a) through 4(d) for that distribution, (ii) you include a conspicuous notice in the 161executable version, related documentation and collateral materials stating that the Source Code version of the 162Licensed Product is available under the terms of this License, including a description of how and where you have 163fulfilled the obligations of Section 4(b), and (iii) you make it clear that any terms that differ from this License 164are offered by you alone, not by Licensor or any Contributor. You hereby agree to indemnify the Licensor and every 165Contributor for any liability incurred by Licensor or such Contributor as a result of any terms you offer. 166 167f. Distribution of Derivative Works. You may create Derivative Works (e.g., combinations of some or all of the 168Licensed Product with other code) and distribute the Derivative Works as products under any other license you select, 169with the proviso that the requirements of this License are fulfilled for those portions of the Derivative Works that 170consist of the Licensed Product or any Modifications thereto. 171 172 1735. Inability to Comply Due to Statute or Regulation. If it is impossible for you to comply with any of the 174terms of this License with respect to some or all of the Licensed Product due to statute, judicial order, or 175regulation, then you must (i) comply with the terms of this License to the maximum extent possible, (ii) cite the 176statute or regulation that prohibits you from adhering to the License, and (iii) describe the limitations and the 177code they affect. Such description must be included in the LEGAL file described in Section 4(d), and must be included 178with all distributions of the Source Code. Except to the extent prohibited by statute or regulation, such 179description must be sufficiently detailed for a recipient of ordinary skill at computer programming to be able to 180understand it. 181 182 1836. Application of This License. This License applies to code to which Licensor or Contributor has attached the 184Notice in Exhibit A, which is incorporated herein by this reference. 185 186 1877. Versions of This License. 188 189a. New Versions. Licensor may publish from time to time revised and/or new versions of the License. 190 191b. Effect of New Versions. Once Licensed Product has been published under a particular version of the License, 192you may always continue to use it under the terms of that version. You may also choose to use such Licensed Product 193under the terms of any subsequent version of the License published by Licensor. No one other than Licensor has the 194right to modify the terms applicable to Licensed Product created under this License. 195 196c. Derivative Works of this License. If you create or use a modified version of this License, which you may do 197only in order to apply it to software that is not already a Licensed Product under this License, you must rename your 198license so that it is not confusingly similar to this License, and must make it clear that your license contains 199terms that differ from this License. In so naming your license, you may not use any trademark of Licensor or any 200Contributor. 201 202 2038. Disclaimer of Warranty. LICENSED PRODUCT IS PROVIDED UNDER THIS LICENSE ON AN AS IS BASIS, WITHOUT WARRANTY 204OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, WARRANTIES THAT THE LICENSED PRODUCT IS FREE 205OF DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING. THE ENTIRE RISK AS TO THE QUALITY AND 206PERFORMANCE OF THE LICENSED PRODUCT IS WITH YOU. SHOULD LICENSED PRODUCT PROVE DEFECTIVE IN ANY RESPECT, YOU (AND 207NOT THE LICENSOR OR ANY OTHER CONTRIBUTOR) ASSUME THE COST OF ANY NECESSARY SERVICING, REPAIR OR CORRECTION. THIS 208DISCLAIMER OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF LICENSED PRODUCT IS AUTHORIZED 209HEREUNDER EXCEPT UNDER THIS DISCLAIMER. 210 211 2129. Termination. 213 214a. Automatic Termination Upon Breach. This license and the rights granted hereunder will terminate 215automatically if you fail to comply with the terms herein and fail to cure such breach within thirty (30) days of 216becoming aware of the breach. All sublicenses to the Licensed Product that are properly granted shall survive any 217termination of this license. Provisions that, by their nature, must remain in effect beyond the termination of this 218License, shall survive. 219 220b. Termination Upon Assertion of Patent Infringement. If you initiate litigation by asserting a patent 221infringement claim (excluding declaratory judgment actions) against Licensor or a Contributor (Licensor or 222Contributor against whom you file such an action is referred to herein as Respondent) alleging that Licensed Product 223directly or indirectly infringes any patent, then any and all rights granted by such Respondent to you under Sections 2241 or 2 of this License shall terminate prospectively upon sixty (60) days notice from Respondent (the "Notice 225Period") unless within that Notice Period you either agree in writing (i) to pay Respondent a mutually agreeable 226reasonably royalty for your past or future use of Licensed Product made by such Respondent, or (ii) withdraw your 227litigation claim with respect to Licensed Product against such Respondent. If within said Notice Period a reasonable 228royalty and payment arrangement are not mutually agreed upon in writing by the parties or the litigation claim is not 229withdrawn, the rights granted by Licensor to you under Sections 1 and 2 automatically terminate at the expiration of 230said Notice Period. 231 232c. Reasonable Value of This License. If you assert a patent infringement claim against Respondent alleging 233that Licensed Product directly or indirectly infringes any patent where such claim is resolved (such as by license or 234settlement) prior to the initiation of patent infringement litigation, then the reasonable value of the licenses 235granted by said Respondent under Sections 1 and 2 shall be taken into account in determining the amount or value of 236any payment or license. 237 238d. No Retroactive Effect of Termination. In the event of termination under Sections 9(a) or 9(b) above, all 239end user license agreements (excluding licenses to distributors and resellers) that have been validly granted by you 240or any distributor hereunder prior to termination shall survive termination. 241 242 24310. Limitation of Liability. UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT (INCLUDING NEGLIGENCE), 244CONTRACT, OR OTHERWISE, SHALL THE LICENSOR, ANY CONTRIBUTOR, OR ANY DISTRIBUTOR OF LICENSED PRODUCT, OR ANY SUPPLIER 245OF ANY OF SUCH PARTIES, BE LIABLE TO ANY PERSON FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF 246ANY CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF GOODWILL, WORK STOPPAGE, COMPUTER FAILURE OR 247MALFUNCTION, OR ANY AND ALL OTHER COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN INFORMED OF THE 248POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY 249RESULTING FROM SUCH PARTYS NEGLIGENCE TO THE EXTENT APPLICABLE LAW PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO 250NOT ALLOW THE EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS EXCLUSION AND LIMITATION MAY 251NOT APPLY TO YOU. 252 253 25411. Responsibility for Claims. As between Licensor and Contributors, each party is responsible for claims and 255damages arising, directly or indirectly, out of its utilization of rights under this License. You agree to work with 256Licensor and Contributors to distribute such responsibility on an equitable basis. Nothing herein is intended or 257shall be deemed to constitute any admission of liability. 258 259 26012. U.S. Government End Users. The Licensed Product is a commercial item, as that term is defined in 48 C.F.R. 2612.101 (Oct. 1995), consisting of commercial computer software and commercial computer software documentation, as such 262terms 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 263227.7202-4 (June 1995), all U.S. Government End Users acquire Licensed Product with only those rights set forth 264herein. 265 266 26713. Miscellaneous. This License represents the complete agreement concerning the subject matter hereof. If any 268provision of this License is held to be unenforceable, such provision shall be reformed only to the extent necessary 269to make it enforceable. This License shall be governed by California law provisions (except to the extent applicable 270law, if any, provides otherwise), excluding its conflict-of-law provisions. You expressly agree that any litigation 271relating to this license shall be subject to the jurisdiction of the Federal Courts of the Northern District of 272California or the Superior Court of the County of Santa Clara, California (as appropriate), with venue lying in Santa 273Clara County, California, with the losing party responsible for costs including, without limitation, court costs and 274reasonable attorneys fees and expenses. The application of the United Nations Convention on Contracts for the 275International Sale of Goods is expressly excluded. You and Licensor expressly waive any rights to a jury trial in 276any litigation concerning Licensed Product or this License. Any law or regulation that provides that the language of 277a contract shall be construed against the drafter shall not apply to this License. 278 279 28014. Definition of You in This License. You throughout this License, whether in upper or lower case, means an 281individual or a legal entity exercising rights under, and complying with all of the terms of, this License or a 282future version of this License issued under Section 7. For legal entities, you includes any entity that controls, is 283controlled by, or is under common control with you. For purposes of this definition, control means (i) the power, 284direct or indirect, to cause the direction or management of such entity, whether by contract or otherwise, or (ii) 285ownership of fifty percent (50%) or more of the outstanding shares, or (iii) beneficial ownership of such entity. 286 287 28815.
