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