Tsinghua University patented a heart and brain product. Is this product really useful?

Of course it works. Although it may not be used much now, it will definitely be useful when the technology is developed in the future. In addition, patent applications are actually subsidized. Shanghai Qingpu has a subsidy of 8000 yuan. It feels good to see it here when the elephant knows how to produce. People who often apply for patents should know that.
