How much can a patent of rust-proof nut be sold to China Railway Corporation? Fastener consultant Yu Wenlong thinks that China Railway Corporation will not buy your nut patent and doesn't believe your patent at all. Moreover, your patented products are really good, which may not be suitable for China Railway Corporation, and China Railway Corporation itself does not produce nuts. Yu Wenlong, a fastener consultant, believes that new products can only enter China Railway Corporation after layers of examination and testing, and the initial investment is very large, and the consequences are unpredictable. Therefore, fastener consultant Yu Wenlong thinks that China Railway Corporation will not buy your nut patent.
Yu Wenlong, a fastener consultant, thinks it's best to look up relevant information yourself. Everything I got online was fake. If you don't know how to pretend, you can answer casually. It is simply false or deceptive, which will directly mislead you and even hurt you.
