On Wednesday a US jury rejected Katherine Jackson's claim that AEG should not have hired Conrad Murray, the physician who was charged with involuntary manslaughter, as singer's personal physician.
Katherine attempted to hold AEG responsible for Michel's death by arguing that they hired Dr Murray without considering whether he was fit for the job, a claim that AEG denied.
The jury concluded that the doctor was not unfit for the position and that the company had not been negligent in hiring him.
Dr Murray was convicted of involuntary manslaughter in 2011 after giving Michael the overdose that led to his death, while he prepared for a series of comeback shows.
Katherine, who is the legal guardian of Michael's three children, was seeking hundreds of millions of dollars in damages for herself and her grandchildren.
The King of Pop's sudden passing on 25 June 2009 shocked fans and musicians across the world.
Michael tragically died at the age of 50 after suffering a cardiac arrest during the run up to his This Is It series of concerts in London.
