Inquiry (采购产品): Marketing information I have a patent pending for a safety platform temporary manhole cover that a person exercising the underground water valves can stand on, with an adjustable patented ring for placement and stabilization of the key. I have received an award from the City of Roseville, CA, environmental utilities, for the design and safety of this item and am interested in selling the patent/design to interested parties.
