X Patent Wiki

This is the beginning of a wiki for a group project to track down missing patents or data associated with them. The patent office fire in 1836 destroyed about 10,000 of the earliest US patents. At that time there were two copies of each patent, one at the patent office where they were destroyed by the fire and a second copy with the inventor. About 2,000 of the inventor's copies have been recovered.
