How much can I get for inventing a lamp (patent)?

It depends on practical value. If it is an ordinary lamp, then the market competition is too great now, and it will not have too optimistic value; If it is a smart light, it can be used in the construction of a smart city, then the patent is ok.

Therefore, in the above example, we can see that the value of a patent ultimately depends on the market. If you say a patent is valuable, it is worthless. This takes into account the value of the patent itself, market value, technical value and so on.

Hope to adopt, thank you!
