My apologies for=20= not being able to come in earlier on these posts. Yes, in summary, publication within a book of previously copyrighted=20 material is itself an infringement of copyright, and then the fact that=20= patents may be incorporated within that is further infringement. If the=20= code within Loizou's Speech Enhancement book does not use the same code o= r=20 patents then this might not be an infringement (other than trade name). = I=20 would hope so since to the best of our knowledge Mathworks don't have a=20= license agreement to be able to publish or distribute PESQ.=20 Regardless of source or application it is everyone's liability to care=20= about third parties' intellectual property rights, whether they are=20 patents, copyrights or trademarks. There are various examples that could be considered, but probably that of= =20 pharmaceutical R&D is most analogous here. Papers are published all t= he=20 time of copyrighted and patented material, but it is very well understood= =20 that those developments are strongly defended if there is ever indication= =20 of infringement. Once again, I will say that the offer is there, to use a fully conformant= =20 time limited version of PESQ, for qualified academic purposes, on=20 application from OPTICOM.=20 Best regards, Graham Graham Rousell Business Development Tel: +49 9131 5302022 ____________________________________________________________ O P T I C O M - The Perceptual Quality Experts. ____________________________________________________________ =20 OPTICOM Dipl.-Ing.
