That said, whatever work another person does with your process will stil be different from your work.
Imagine if the inventor of the potters wheel had said "I spent years making this thing work! No-one else can make pottery using this technique!". Or if there was a copyright fight over calculus.
In papermaking, there are different additives you put in your pulp to help it bind together. You use different ones depending on the type of fiber you're using. If you mix them together, you get some neat effects. I did this by mistake. Later I learned that someone tried to patent mixing those two additives together, as a unique process.
Personally, I like to share stuff. I share recipes and ideas all the time. Maybe someone else will do niftier things with my idea than I could.
