What's the difference between international patent and domestic patent in application? Are the patents applied by general enterprises all domestic patents?

If your invention and creation want to be protected in many foreign countries, if you haven't decided which countries to apply for protection for your invention and creation, apply for PCT (so-called international patent).

Patents are regional. For example, the United States Patent and Trademark Office granted a certain technology patent right, but China did not recognize it, so it needed to apply separately in China.

Most people apply for PCT because their technology is protected by patents abroad. The rights obtained by domestic patent applications are only valid in China and are not protected by law in other countries.

Enterprises in our country can see where the products are sold. If the sales market is in China, it is essential to obtain a patent right in China. If they want to sell overseas, they should also apply for patent protection in the country where they want to sell.
