Inventor's Copy of Letters Patent for Carterfone, US Patent 3100818

Description (Brief):

This is the inventor's copy of U.S. Patent #3,100,818 issued to Thomas Carter in 1963 for the Carterfone device. The United States Constitution authorizes Congress “to promote the progress of science and useful arts, by securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries.” The idea is to encourage invention by granting inventors a legal monopoly for a given period of time, today that period is 20 years. In November 1959 Carter filed for a patent on his method of wirelessly connecting telephone and radio conversations. He received this sealed and ribboned copy almost 4 years later.
