How long does it usually take to attract investment by patent auction?

This is uncertain. It's like selling a house and then making an announcement in the newspaper. Then you ask, when can the house be sold? But generally speaking, Golden Hammer Baocheng Club has a relatively mature and stable customer base. Once the announcement of investment promotion is issued, interested buyers should come to consult, so generally speaking, the investment promotion time is about 16 days from the date of announcement. The auction time is determined according to the official announcement of the auction. The auction announcement will indicate the time and place of the auction, and the announcement time shall not be less than 7 days.
