23 Lucent Public License Version 1.02
25 THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS PUBLIC
26 LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR DISTRIBUTION OF THE
27 PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.
33 a. in the case of Lucent Technologies Inc. ("LUCENT"), the Original
35 b. in the case of each Contributor,
37 i. changes to the Program, and
38 ii. additions to the Program;
40 where such changes and/or additions to the Program were added to the
41 Program by such Contributor itself or anyone acting on such
42 Contributor's behalf, and the Contributor explicitly consents, in
43 accordance with Section 3C, to characterization of the changes and/or
44 additions as Contributions.
46 "Contributor" means LUCENT and any other entity that has Contributed a
47 Contribution to the Program.
49 "Distributor" means a Recipient that distributes the Program,
50 modifications to the Program, or any part thereof.
52 "Licensed Patents" mean patent claims licensable by a Contributor
53 which are necessarily infringed by the use or sale of its Contribution
54 alone or when combined with the Program.
56 "Original Program" means the original version of the software
57 accompanying this Agreement as released by LUCENT, including source
58 code, object code and documentation, if any.
60 "Program" means the Original Program and Contributions or any part
63 "Recipient" means anyone who receives the Program under this
64 Agreement, including all Contributors.
68 a. Subject to the terms of this Agreement, each Contributor hereby
69 grants Recipient a non-exclusive, worldwide, royalty-free copyright
70 license to reproduce, prepare derivative works of, publicly display,
71 publicly perform, distribute and sublicense the Contribution of such
72 Contributor, if any, and such derivative works, in source code and
75 b. Subject to the terms of this Agreement, each Contributor hereby
76 grants Recipient a non-exclusive, worldwide, royalty-free patent
77 license under Licensed Patents to make, use, sell, offer to sell,
78 import and otherwise transfer the Contribution of such Contributor, if
79 any, in source code and object code form. The patent license granted
80 by a Contributor shall also apply to the combination of the
81 Contribution of that Contributor and the Program if, at the time the
82 Contribution is added by the Contributor, such addition of the
83 Contribution causes such combination to be covered by the Licensed
84 Patents. The patent license granted by a Contributor shall not apply
85 to (i) any other combinations which include the Contribution, nor to
86 (ii) Contributions of other Contributors. No hardware per se is
89 c. Recipient understands that although each Contributor grants the
90 licenses to its Contributions set forth herein, no assurances are
91 provided by any Contributor that the Program does not infringe the
92 patent or other intellectual property rights of any other entity. Each
93 Contributor disclaims any liability to Recipient for claims brought by
94 any other entity based on infringement of intellectual property rights
95 or otherwise. As a condition to exercising the rights and licenses
96 granted hereunder, each Recipient hereby assumes sole responsibility
97 to secure any other intellectual property rights needed, if any. For
98 example, if a third party patent license is required to allow
99 Recipient to distribute the Program, it is Recipient's responsibility
100 to acquire that license before distributing the Program.
102 d. Each Contributor represents that to its knowledge it has sufficient
103 copyright rights in its Contribution, if any, to grant the copyright
104 license set forth in this Agreement.
108 A. Distributor may choose to distribute the Program in any form under
109 this Agreement or under its own license agreement, provided that:
111 a. it complies with the terms and conditions of this Agreement;
113 b. if the Program is distributed in source code or other tangible
114 form, a copy of this Agreement or Distributor's own license agreement
115 is included with each copy of the Program; and
117 c. if distributed under Distributor's own license agreement, such
120 i. effectively disclaims on behalf of all Contributors all warranties
121 and conditions, express and implied, including warranties or
122 conditions of title and non-infringement, and implied warranties or
123 conditions of merchantability and fitness for a particular purpose;
124 ii. effectively excludes on behalf of all Contributors all liability
125 for damages, including direct, indirect, special, incidental and
126 consequential damages, such as lost profits; and
127 iii. states that any provisions which differ from this Agreement are
128 offered by that Contributor alone and not by any other party.
130 B. Each Distributor must include the following in a conspicuous
131 location in the Program:
133 Copyright (C) 2003, Lucent Technologies Inc. and others. All Rights
136 C. In addition, each Contributor must identify itself as the
137 originator of its Contribution in a manner that reasonably allows
138 subsequent Recipients to identify the originator of the Contribution.
139 Also, each Contributor must agree that the additions and/or changes
140 are intended to be a Contribution. Once a Contribution is contributed,
141 it may not thereafter be revoked.
143 4. COMMERCIAL DISTRIBUTION
145 Commercial distributors of software may accept certain
146 responsibilities with respect to end users, business partners and the
147 like. While this license is intended to facilitate the commercial use
148 of the Program, the Distributor who includes the Program in a
149 commercial product offering should do so in a manner which does not
150 create potential liability for Contributors. Therefore, if a
151 Distributor includes the Program in a commercial product offering,
152 such Distributor ("Commercial Distributor") hereby agrees to defend
153 and indemnify every Contributor ("Indemnified Contributor") against
154 any losses, damages and costs (collectively"Losses") arising from
155 claims, lawsuits and other legal actions brought by a third party
156 against the Indemnified Contributor to the extent caused by the acts
157 or omissions of such Commercial Distributor in connection with its
158 distribution of the Program in a commercial product offering. The
159 obligations in this section do not apply to any claims or Losses
160 relating to any actual or alleged intellectual property infringement.
161 In order to qualify, an Indemnified Contributor must: a) promptly
162 notify the Commercial Distributor in writing of such claim, and b)
163 allow the Commercial Distributor to control, and cooperate with the
164 Commercial Distributor in, the defense and any related settlement
165 negotiations. The Indemnified Contributor may participate in any such
166 claim at its own expense.
168 For example, a Distributor might include the Program in a commercial
169 product offering, Product X. That Distributor is then a Commercial
170 Distributor. If that Commercial Distributor then makes performance
171 claims, or offers warranties related to Product X, those performance
172 claims and warranties are such Commercial Distributor's responsibility
173 alone. Under this section, the Commercial Distributor would have to
174 defend claims against the Contributors related to those performance
175 claims and warranties, and if a court requires any Contributor to pay
176 any damages as a result, the Commercial Distributor must pay those
181 EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS
182 PROVIDED ON AN"AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY
183 KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY
184 WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY
185 OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely
186 responsible for determining the appropriateness of using and
187 distributing the Program and assumes all risks associated with its
188 exercise of rights under this Agreement, including but not limited to
189 the risks and costs of program errors, compliance with applicable
190 laws, damage to or loss of data, programs or equipment, and
191 unavailability or interruption of operations.
193 6. DISCLAIMER OF LIABILITY
195 EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR
196 ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT,
197 INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING
198 WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF
199 LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING
200 NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR
201 DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED
202 HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
206 Recipient agrees that Recipient alone is responsible for compliance
207 with the United States export administration regulations (and the
208 export control laws and regulation of any other countries).
212 If any provision of this Agreement is invalid or unenforceable under
213 applicable law, it shall not affect the validity or enforceability of
214 the remainder of the terms of this Agreement, and without further
215 action by the parties hereto, such provision shall be reformed to the
216 minimum extent necessary to make such provision valid and enforceable.
218 If Recipient institutes patent litigation against a Contributor with
219 respect to a patent applicable to software (including a cross-claim or
220 counterclaim in a lawsuit), then any patent licenses granted by that
221 Contributor to such Recipient under this Agreement shall terminate as
222 of the date such litigation is filed. In addition, if Recipient
223 institutes patent litigation against any entity (including a
224 cross-claim or counterclaim in a lawsuit) alleging that the Program
225 itself (excluding combinations of the Program with other software or
226 hardware) infringes such Recipient's patent(s), then such Recipient's
227 rights granted under Section 2(b) shall terminate as of the date such
230 All Recipient's rights under this Agreement shall terminate if it
231 fails to comply with any of the material terms or conditions of this
232 Agreement and does not cure such failure in a reasonable period of
233 time after becoming aware of such noncompliance. If all Recipient's
234 rights under this Agreement terminate, Recipient agrees to cease use
235 and distribution of the Program as soon as reasonably practicable.
236 However, Recipient's obligations under this Agreement and any licenses
237 granted by Recipient relating to the Program shall continue and
240 LUCENT may publish new versions (including revisions) of this
241 Agreement from time to time. Each new version of the Agreement will be
242 given a distinguishing version number. The Program (including
243 Contributions) may always be distributed subject to the version of the
244 Agreement under which it was received. In addition, after a new
245 version of the Agreement is published, Contributor may elect to
246 distribute the Program (including its Contributions) under the new
247 version. No one other than LUCENT has the right to modify this
248 Agreement. Except as expressly stated in Sections 2(a) and 2(b) above,
249 Recipient receives no rights or licenses to the intellectual property
250 of any Contributor under this Agreement, whether expressly, by
251 implication, estoppel or otherwise. All rights in the Program not
252 expressly granted under this Agreement are reserved.
254 This Agreement is governed by the laws of the State of New York and
255 the intellectual property laws of the United States of America. No
256 party to this Agreement will bring a legal action under this Agreement
257 more than one year after the cause of action arose. Each party waives
258 its rights to a jury trial in any resulting litigation.
