How can I buy the patent I want?

The official of the State Information Bureau does not buy or sell patents, so it is recommended to find a reliable intellectual property company to do it. The general platform will classify patents and sell them uniformly. Before making a decision, you can ask to see the description abstract of the copy, or you can find the IPC classification number of this patent text to determine whether it is accurate. If it is accurate, then you can adjust all the documents under this classification number to see if it is the patent you want.
