Lawyer Yury Kostanov said that the defense would appeal to the Supreme Court's chairman.
"We will ask the chairman to repeal the Supreme Court's ruling as being illegitimate and unfounded," Kostanov said.
On March 1, the Moscow City Court acquitted the doctors of carrying out an illegal transplant.
"The investigation found the doctors not guilty," the judgment read.
The Prosecutor's Office had accused a medical team at Hospital No. 20 of conspiring to murder a patient brought to the hospital with closed craniocerebral injury on April 11, 2003.
During the trial, the prosecutor demanded prison terms of various lengths for the hospital's emergency crew and two experts from the Moscow organ donation center.
But the court ruled that the doctors had started preparations to remove organs only after the patient was declared dead.
"The court fully acquits the defendants," the ruling read.
The Moscow City Court will start hearing the case again August 1.
