When Abraham Lincoln was elected as President, the Mississippi U.S. Trademark and Patent Office member Rufus Randolph Rhodes resigned from his post. Eventually, Rufus Rhodes joined the newly formed the Confederate States Patent Office and moved to Richmond, Virginia after he was elected as the Commisioner of the Confederate States Patents on May 22, 1861.
Over two hundred patents were issued by the Confederates States Patent Office between 1861 to 1865. A book on the “Rules and Directions for Proceedings of the Confederate States Patent Office” was one of the few documents that were preserved after most of the business district of the city of Richmond burnt down.
