>Recipes explicitly cannot be copyrighted Yes; however, as the link you provide explains if more than just a simple listing of ingredients (i.e. description, pictures, ect...) the same can be awarded copyright. A copyright on a cook book is still the industry standard, because a single filing/fee covers an entire book of recipes. >I've recently been down the patent research path myself and to me it is still not clear what creates a patentable non-obvious combination of technologies, and what is simply not patentable. In many cases it seems based on the patent reviewer's subjectivity. 100%, much like trademark and copyright much is left to the subjectivity of the reviewer. I will say this about the patent office (compared to trademarks), the reviewers are generally very well educated in their respective fields (engineering, medicine, ect...). The only other way to gain more insight into obviousness standard is reading case law/precedent.
