108 TRADEMARK: |
|
109 |
|
110 The name "libpng" has not been registered by the Copyright owner |
|
111 as a trademark in any jurisdiction. However, because libpng has |
|
112 been distributed and maintained world-wide, continually since 1995, |
|
113 the Copyright owner claims "common-law trademark protection" in any |
|
114 jurisdiction where common-law trademark is recognized. |
|
115 |
|
116 OSI CERTIFICATION: |
|
117 |
|
118 Libpng is OSI Certified Open Source Software. OSI Certified Open Source is |
|
119 a certification mark of the Open Source Initiative. OSI has not addressed |
|
120 the additional disclaimers inserted at version 1.0.7. |
|
121 |
|
122 EXPORT CONTROL: |
|
123 |
|
124 The Copyright owner believes that the Export Control Classification |
|
125 Number (ECCN) for libpng is EAR99, which means not subject to export |
|
126 controls or International Traffic in Arms Regulations (ITAR) because |
|
127 it is open source, publicly available software, that does not contain |
|
128 any encryption software. See the EAR, paragraphs 734.3(b)(3) and |
|
129 734.7(b). |
