On November 24, 1981, Dr. Drolet and Mr. Charland received patent approval for their electro-magnetic therapeutic system. Their drawings, as portrayed within the Canadian patent, labeled the device "Ri - 2000 MAGNETOTHERAPY SYSTEM". By 1983, Dr. Drolet and Mr. Charland were issued another patent titled " ELECTRO-MAGNETIC THERAPEUTIC SYSTEM AND METHOD " which described the " Ri - 2000 " in much further details and labeled the device as " Ri -2000 RHUMART-THERAPY SYSTEM ". This second patent maintained many similar characteristics to the 1981 patent. In fact both patents drew and labeled their devices with " RODROL INSTRUMENTATION INC. ".
