Why was intellectual property acquired within three years?

If this provision is not specific, it is just a comprehensive consideration. You think, if there is support, he can't approve it without inspecting your company, but he can't ask your company for six years or more. Then the materials you need to hand in and the materials he needs to see are unrealistic, but if it is only 1 year, it is not enough for him to understand and judge. So three years is just right. So there is no way, since it has been published, it must be observed. What high-tech problems do you have? I'm Yang from Beijing Sheng Bang Intellectual Property Agency Co., Ltd.
