   4 The name "libpng" has not been registered by the Copyright owners
   5 as a trademark in any jurisdiction.  However, because libpng has
   6 been distributed and maintained world-wide, continually since 1995,
   7 the Copyright owners claim "common-law trademark protection" in any
   8 jurisdiction where common-law trademark is recognized.
