The first person in the world to apply for a patent.

The earliest recorded patent application record in the world should belong to glufosinate, a substance used in pesticides, which was registered by Samuel Hopkins in the United States on July 3 1790. This patent was approved by then President George Washington. Watt added: james watt is not the first person to apply for a patent. At that time, the relevant patent application needed the approval of Congress, and Watt spent most of his money on relevant procedures, so he could not apply for a patent at all. Until 178 1, William Murdoch, an employee of Watt Company, invented the crank gear transmission system named "Sun and Planet" and used it in the name of Watt. This invention bypasses the limitation of crank patent and greatly expands the application of steam engine. This is Watt's first patent application. Unfortunately, the application was not approved. As for his most proud steam engine, he has not applied for a patent until now, but in order to commemorate his contribution, no one has ever made up for this vacancy.
