Hi Christine, Thank you for your feedback. It’s certainly a mistake that is often made, but the differentiation must be made between free access to ITU information, given the constraints the ITU apply of no reproduction or utilization in any form, without
permission in writing from the ITU, and possible copyright and patent infringement resulting from the use of that information. Potential users should in the first instance go to the ITU-T website to review the recommendation, which should include a statement
regarding potential Intellectual Property Rights. I believe there is nothing stopping any organisation (commercial or non-commercial) with an interest to develop algorithms from attending the ITU meetings personally or through their national co-ordination group,
and thereby compete with the proponents presented, possibly even with the aim of providing copyright and patent free tools. That said it takes a lot of time and investment to be able to do this (travel alone!), which needs to be recovered from somewhere and
then ploughed back into maintenance and future developments. That is why OPTICOM can act both as the shop front for these tools as well as a developer, to ensure that the collected royalties from commercial use can be distributed to the rightful contributors.

Dear Graham: Thank you for addressing this. Somehow I had the idea that because the ITU is a United Nations agency, its work is freely available to all, or at least to those countries having UN membership. Christine Rankovic -----Original Message----- Dear Nicolas, Thank you for your very detailed and precise response. My apologies for not being able to come in earlier on these posts. Yes, in summary, publication within a book of previously copyrighted
material is itself an infringement of copyright, and then the fact that
patents may be incorporated within that is further infringement. If the
code within Loizou's Speech Enhancement book does not use the same code or
patents then this might not be an infringement (other than trade name). I
would hope so since to the best of our knowledge Mathworks don't have a
license agreement to be able to publish or distribute PESQ.
Regardless of source or application it is everyone's liability to care
about third parties' intellectual property rights, whether they are
patents, copyrights or trademarks. There are various examples that could be considered, but probably that of
pharmaceutical R&D is most analogous here. Papers are published all the
time of copyrighted and patented material, but it is very well understood
that those developments are strongly defended if there is ever indication
of infringement. Once again, I will say that the offer is there, to use a fully conformant
time limited version of PESQ, for qualified academic purposes, on
application from OPTICOM.
