I've always been under the (possibly misguided) impression that R&D claims were possible on, say, brewers inventing new tastes / receipes. admittedly this has come from marketing from R&D 'specialists'.
One of my clients received a letter a few weeks ago politely reminding them that R&D claims must be for scientific or technological advancement.
Should I take it from this that claims for receipes are invalid? What are your thoughts? Have you ever done any?
