It is the wish of many individual inventors to turn patents into products, especially into hot-selling products on the market. However, the reality is cruel. Having a patent may not necessarily translate into economic benefits. Looking at the Chinese patent database, we can see how many patents are lying silently in archives and hard drives, either abandoned by the patentee without paying fees, or waiting until the patent expires without any return. The most famous person who combines technological inventions and business patents well is Edison. Tesla fell into Edison's hands back then. Now many people think Edison is unkind, but in modern times, many depressed inventors hold patents but Judging from the fact that there is no way to convert products, Edison is actually a person who understands technology and is good at management.
