What is the impact of "product sales" before patent application on American patent rights?

In the United States, if the patentee sells or promises to sell the product before the patent application, he has a one-year grace period to submit the relevant patent application, which is called a bar on sale. Although the United States has a one-year grace period for sales, there is no similar provision in other countries, so this kind of sales behavior will directly lead to the loss of patent rights.
