theora - Jan 2015 - NHW Image codec

Hello,

Yes, that's right.I still think that it would have more weight if I could
claim that Xiph has reviewed the source code and find that the NHW codec is
royalty/patent-free (better than me alone claiming this...).Maybe it was in
this sense that Ralph Giles answered me?

Cheers,
Raphael

That's not a guarantee that anyone can make, not even a patent attorney. 
The current landscape is such that "being clear of patent concerns" is
impossible.  Someone can be destroyed by the legal process that results in them
being exonerated, but then left with no will nor resources to continue
development.

I don't say this to scare you away, just understand that asking Xiph to
"clear" the patent issues doesn't make sense.  Xiph is a
non-profit organization that advances the cause of free, open, and royalty-free
technologies, but cannot offer a technically legal service as requested.

Hello,

Ok, and that's too many work to review a source code.In my codec, I have 3
compression schemes, I think 2 are not patented, but the third... I don't
know.For the rest, I think my codec is patent-free (I don't use
SPIHT,EZW,zerotree methods), even the wavelet transform is new and don't
use the lifting scheme nor the convolution product.

Else, if you found time to review the codec, do not hesitate to let me know
what you think of it and if you would have remarks.Would be much
appreciated.

Cheers,
Raphael
