Very interesting podcast. I am not a lawyer but it struck me that the value of IP-free industries, such as cookery, magic and fashion, is in large part a combination of the innovative idea, the "ingredients" and the process. In contrast, once a book or piece of music has been created, it can be easily duplicated. So, give me a recipe and you can be sure that I will not create a meal of the same value as a Michelin-starred chef - I lack the process skills, the quality of ingredients, the "tricks of the trade" etc etc. Similarly, give me the instructions for a magic trick and my ham fisted-ness will ensure that I won't be able to replicate the experience for the audience. Ditto re black material and the pattern for a chanel dress - it's not going to happen.
