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