This was posted on the Apache legal mail system. I thought it might be
of general interest to other people as well, so I will repost here:
Here is better, more complete data about the Copyrights in NuttX. The
apps/ directory does contain a considerable amount of ported 3rd party
code which which throws thing off a bit. The core OS is exceptionally
clean with mostly original code; the applications are a hodge-podge of
original and ported code.
Identification of Copyright notices was accomplished using 'grep'. It
is prone to some errors in that it does not understand the context of
the Copyright. Some of these may not be Copyrights on the file itself
be some reference to other Copyrighted material. 'grep' isn't smart
enough to know the difference.:
This should be a complete accounting of all Copyrights other than any
possible (probable) human errors. The executive summary is that I hold
88% of copyrights. 171 other people/organizations hold also have
Copyrights.

[1] Text, html files, image files have no copyright notices.
Build-related files, scripts, and source files do.
[2] Files may have multiple copyright on them for a variety of reasons.
[3] ICLA filed
[3] SGA filed
[5] Major contributors from Sony have signed ICLAs (representing only
themselves)
[6] Pinecone and FishSemi are subsidiaries of Xiaomi, major contributors
have signed ICLAs (representing only themselves)
[7] Anthony Merlino has signed an ICLA and is the co-founder and CTO
of, now, Verge Areo
[8] I am not certain if Ken, David or Brennan have submitted ICLAs yet.
They are expected. Ken has also verbally agreed to release his
copyrights in the past if necessary.
[9] NX Engineering, S.A, is a defunct business wholly owned by Gregory
Nutt. I need to change the Copyright holder name
to Gregory Nutt.
