This is an inquiry message about US Patent 4,598,581 in the 108th China Canton Fair. (这是一条买家关于"US Patent 4,598,581"的询盘信息，来自第108届中国广交会。)Inquiry Message (询盘信息) US Patent 4,598,581 I was the inventor for the US Patent referenced above, which was assigned to one of my employers. Am curious to know if you produced this item for FMC Corporation during the life of the patent. I met with some of your company personnel when we were developing this invention in the 80s. I am now a 76-year-old FMC retiree, and may have an upcoming use for this product in another recent invention. Would like to hear from you via your response to this e-mail. I am a Minnesotan by birth, so had hoped this became a profitable product for you.
