I was curious about the actual patent no.1: The first US patent "was granted to Samuel Hopkins for a process of making potash, an ingredient used in fertilizer on July 31." US Patent No.1 "was granted to Senator John Ruggles for a traction wheel for steam locomotives on July 13. The 9,957 patents granted before the numbering system are now known as the X-patents." ref: https://www.uspto.gov/patents/milestones https://www.uspto.gov/patents/milestones
