To me, the interesting part was<p>"In 2006, we filed an international patent application for the cultivation of morels in collaboration with a private patent agency. The application described, among other things, two of the most central cultivation principles which are also used today in our fully developed method for the controlled indoor cultivation of black morels, all-year-round. However, shortly after the application was approved, we decided, on the advice of the Danish Patent Directorate, to withdraw the application before it was published worldwide, as in practice it is relatively easy to circumvent a patent of this type. We are therefore now in a position where we have chosen once and for all to keep the key points of our method secret, not least because we are currently considering the commercial possibilities. This is why we are unfortunately unable to provide any more information on the cultivation process than is given on this website."<p>in combination with their description of how they and many others spent many years unsuccessfully trying to reproduce a 30 year old USA patent that also claimed an ability to cultivate morels indoors.
