Patent licensing in patent law

Cross-licensing patents are generally developed on the basis of B patents, but A patents also have their own uniqueness, and cross-licensing is to encourage inventions. If it has been cross-licensed, it is a matter between two patentees and has nothing to do with the third party.

If you want to get a patent, it depends on whether you want to use a patent or b patent. If you want to use the patent, you can apply and reach an agreement with the patent holder. You can also apply to the right holder of patent B, because at this time they are mutually licensed and have the right to use each other.

If China products are only sold in China, we only need to deal with patent matters in China. Patent protection is regional. For example, the obligee can use it directly without applying for a patent in China or participating in the corresponding international patent protection. Japanese enterprises or state-owned enterprises, as long as their activities are in China, are bound by the laws of China and the international agreements to which China is a party. There is not much difference.
