Here is a link to the English version: http://www.wipo.int/about-wipo/en/index.html?wipo_content_frame=/about-wipo/...
It says, vaguely, that we can "use or reproduce" "any information presented". It's hard to see how that amounts to permission to alter and redistribute anything from their website.
To 'use' means to read and learn from and things like that.
To 'reproduce' means to reproduce exactly.
And 'information' is not normally the subject of copyright restrictions. We don't need permission to use _information_ from their site, only to use _text_ from their site. So in that sense, they are only giving bogus permission to do something we can do already.
I would say that this is NOT compatible and should not be used.
