What is the use of patent evaluation report? Why is it always pointed out that investors are willing to cooperate only after making a patent evaluation report? It feels like a scam. fraud

Patent evaluation report is to make an estimate of your patent's situation, benefits and other aspects, and evaluate its value. The evaluation report can only be issued by professional institutions and has legal effect.

When cooperative investment is needed, it is normal for the other party to ask you to issue an evaluation report. Otherwise, who will believe you when you say how much your technology or your business is worth? However, if a state-recognized department issues a report to evaluate its value, investors will be relieved.
