Yes. You see, each country has its own patent system, and they work independently, except that countries have signed up to a treaty that says, &ldquo;If you have got a patent in that country, you can basically bring your application over here, and we'll judge it based on the year you applied for it over there.&rdquo; But other than that, each country has its own criteria for what can be patented and has its own set of patents.
