Patents cover inventions, not products. Some products may have multiple inventions, some patented, some patent pending, some not patentable at all. Some inventions are patented in one country and not in others.
It would be impossible to determine which products might include patents, let alone how many of them there might have ever been in even a single country that issues patents.
