I have a patent, which is a self-heating tank. Convenient and simple … I want to apply it to the coffee market … Do you think it has market value?

First, you should look at your patent itself, whether it is authorized, whether it is stable, how the scope of rights protection is, and how the patent specification is written. . .

Second, see how you use it. A patent itself, if you don't use it, may be worthless before. If you can find a good partner or business model, or if you can transfer or license it, its value can be reflected.
