This was the second time this was done anywhere in the world. The previous occasion was in the United States from 1790 to 1793 under the Patent Act of 1790. Previously, patents were issued on all applications, even if they were direct copies of earlier patents. It was left to the courts to decide validity in the event of a lawsuit.
