The Court of Arbitration for Sport (CAS) on Tuesday rejected the Russian Paralympic Committee's (RPC) appeal against the ban on its participation in the September 7-18 Rio Paralympics, reports Sputnik.
"Seven people are now preparing the documents, and they will send letters to the International Paralympic Committee," Patsev told R-Sport on Saturday.
He added that 23 Russian paralympic athletes had already sent such letters to the IPC that, in turn, promised to respond early next week.
Last month, the World Anti-Doping Agency (WADA) urged IPC to suspend Russia from the Paralympic Games following a report of its independent commission.
The report said Russia had run a state-controlled doping programme. Earlier in August, the IPC imposed a blanket ban on the Russian paralympic team.
