The essence of stocks with independent intellectual property rights and independent core technologies is enterprises with independent intellectual property rights and independent core technologies. When it comes to such enterprises, there must be giants such as Apple, Google, IBM and Microsoft. But these enterprises are not from China. So you say that stocks may be bought, so you say some domestic ones: Midea, Gree, ZTE, China Mobile, China Unicom, BYD, etc. These are enterprises with real strength, and their R&D strength is indeed well-known internationally. In addition, when it comes to patents, Huawei in China is a big brother, but people are not listed and you can't buy their shares.
Note that having independent intellectual property rights does not mean having independent core technologies. The former is relatively easy to do because many things can be packaged, but the latter is difficult to do because the packaged things cannot form core competitiveness. Therefore, just looking at the number of patents under a company's name is actually not enough to show how technically awesome this company is.
