Thanks - I already had that experience... :-)
I'm now in e-mail contact with an ETSI secretary. The problem is:
there's no statement like "AMR codec: Company XYZ. Contact: ...". :-)
To understand the details of different codebooks you need deep knowledge
of audio encoding; thus I don't know if patent A or patent B interfere
with AMR decoding or not...
What I search is either some kind of "AMR license vendor" or - what
I prefer - the solid information that decoding AMR data (using
the 26.073 reference code) doesn't need to be licensed.

Thanks for this tip!
Have a nice day!

That's not completely correct. Read 26.071 first.
The C code is part of the spec. and therefore copyrighted by 3GPP.
And it's no example, it is the bit-exact, mandatory implementation
of the codec.
Wishing a happy day

Hello!
Does anyone know about a patent on the AMR codec?
And if a patent exists - who is contact for licensing?
On the ETSI IPR search there's only mentioned that "Ericsson
claims to have some patents (pending) around AMR".
The ANSI C code example from 3GPP (26.073) is completely
without any notice of patents, copyright or licence.
I'm happy for *any* answer on this!
Thanks,
Klaus
