You might ask Coca-Cola if they know its patent is expired.
They don’t have a patent. It’s a trade secret. They never patented it - which would have provided the ingredient list/manufacturing process/ratio of ingredients for people to see.
That’s why they guard the ingredient list/process so tightly.
Other companies have tried reverse engineering the beverage to mixed success.
Trade secrets have no expiration date - if the company releases the trade secret it becomes open season on the information contained therein.
