There seems to be a bit of confusion. First of all you *can * patent a recipe, but it has to be somehow unique, non-obvious, novel and useful. A failure to achieve any of these will mean the item (recipe or whatever) won’t be issued a patent.
For instance a traditional pound cake is:
A pound of sugar
A pound of flour
A pound of butter
A pound of eggs
No one could’ve ever patented this because there is nothing unique about it. There is nothing in the way the ingredents are combined to produce uniqueness. It’s nothing that could’nt have been thought of before or couldn’t be demonstrated to have been in use for ages.
Second of all it must be demonstratable. You can’t patent an idea. So you’d have to be able to present the recipe in such a way, that no one would’ve thought to do so.
From the US Patent Office Website
What makes an invention “novel”?
What makes an invention “non-obvious”
What makes an invention “useful”
It should be noted though useful can mean pretty much anything. For instance, musical condoms and forks that play music while you eat things have been patented. Thus their usefulness is for fun or novelty.
So you can see even if you discoverd the real formula for Coke you couldn’t patent it because it’s been around so long.
Last time I checked to file for an applicaton for a patent was around $1,500 so you’d better make sure it’s a darn good recipe to recoup your cost.
Remember trade secrets aren’t give the same protection as patents and trademarks. The protection arises mostly through contract. But the key to a trade secret is that it is SECRET. Once someone discloses it, it ceases to be a trade secret and the result is a complex legal mess. All the holder of a trade secret can do is sue the exposer for compensation. In practice it’s not much comfort.
The Uniform Trade Secret Act (not valid in all states and it is at the state level only, not the Federal level) says the remedies include, injuctions against further production, real damages, punitive damages and reasonable attorny fees to recover such awards.
