Why can conflicting applications only evaluate domestic patent applications and not foreign ones?

Patents are regional. Only in which country does a patent apply can it be protected, and this country will no longer be protected by law. Exporting to other countries is not protected by this country, and your patented products may be copied, copied and abused. Any infringement of your patent right in China is legal in this country, and you will not get any benefits. Rnrn If the products are exported to a country where the same products as yours are patented, your products will not be able to reach this country. Otherwise, it is an infringement of others' rights.
