The agency on Saturday issued summons to the former minister and asked him to appear before it on June 10 or 11.
The agency in its charge sheet had said that Deepak Talwar, who is currently in judicial custody, allegedly acted as a middleman to favour foreign private airlines, causing huge loss to national carrier Air India.
"Talwar finalised various communications on behalf of Emirates and Air Arabia to be addressed to the then Minister of Civil Aviation Praful Patel," Special Public Prosecutor (SPP) DP Singh, appearing for the agency, had told Special CBI Judge Anuradha Shukla Bhardwaj on May 1.
Talwar was extradited from Dubai on January 30.
