From what i understand, the patent was granted to Kannalife on one specific condition:

"Dean Petkanas, chief executive officer at KannaLife Sciences, told us that the exclusivity applies only for the development and sale of cannabinoid based therapeutics as antioxidants and neuroprotectants for use in the treatment of hepatic encephalopathy."
