Why should China's products be rewarded by the Japanese intellectual property department? Is there a difference between being granted the invention patent right by the Japanese intellectual property department and being granted it at home? Advantage?
There are geographical restrictions on intellectual property protection. If a patent or trademark is to be protected in other countries, the obligee must also apply in other countries through legal procedures, and only after examination can it be protected by law in that country. Therefore, China laws can only protect patents, trademarks and other intellectual property rights applied for and granted in China (except intellectual property rights that should be protected according to international treaties to which China is a party, such as the well-known foreign trademark). If you want to be protected by intellectual property rights in Japan, you must apply to Japan.
At present, the obligee can also directly apply for patents from other countries in China National Intellectual Property Administration, China. This is based on the simplified procedure of the World Intellectual Property Organization PCT project, which can reduce the cost and time for the obligee to apply. In addition, within the EU, the obligee can also choose to register European trademarks or European design rights and other intellectual property rights (unfortunately, there is no European patent right at present), and after the application is approved, it will receive the same protection throughout the EU.
Of course, there may be bilateral or multilateral treaties between countries, and intellectual property rights obtained in one country are also recognized and protected by the other side, but this is not the norm.
