Second, you can look at the problem from the shoulders of your competitors. If you can't avoid other people's core patents to develop technology, then you can apply for many related peripheral patents around this core patent, forcing competitors not to develop normally, so as to achieve mutual cooperation and gain benefits.
Third, we should improve the innovation mechanism. It is necessary to train employees of enterprises, deeply understand the needs of existing customers and potential customers, so as to carry out purposeful technology research and development. This is a wise patent mining method, that is, "we will give them what they want."
