I had a business that offered recipes for low-fat baked goods for a
couple of years. We looked into copyrighting and my understanding was this:
Recipes CAN BE coprighted. However, any minor change in the
recipe negates the copyright. So if, for instance, a recipe calls for 1
cup of an ingredient and someone changes it to 1 cup minus 1/8 tsp, the
copyright no longer applies. We weren't creating a cookbook, so I'm not
sure how it would work for that; but in our case we would have had to
copyright each individual recipe. Given the cost and the ultimate lack
of protection, we opted not to copyright.
I recently looked into copyrighting again for another business (I'm a
crafter) and found a great deal of information on the internet. I don't
remember the exact address, but I found it simply by doing a search for
"copyright" on one of the search engines.
Hope this helps, Laurel
