If you own a patent, there is no way your competitors could duplicate your methods. Patent could protect your competitive advantage. In other words, if you refer back to economic moat, at this moment, moat is in the patent that protects your technology. As a result you can project your business for the long run. Especially, your company could become a public firm in which common stock could outperform your other food vendors.
Economic moat in this case could reflect the qualitative measurement of your company. You could keep your competition advantage by putting your competitors at the bay for a longer period of time. In other words, extending your profit is highly possible.
Unfortunately, economic moat is difficult to predict quantitatively. This is because economic moat does not have the obvious dollar value. It is, on the other hand, a vital qualitative factor in the business’ success and failure.
