The Nerazzurri, Scudetto winners every season from 2006 to 2010, suffered their third defeat in four games on Sunday in a shock 1-0 reverse against bottom-of-the-table Novara at the San Siro.
But Moratti is not pressing the panic button just yet.
He told Italian newspaper Corriere della Sera: "It may be that we have done something wrong or that we have made mistakes with some decisions. However, I do not think there have been many errors - and not serious errors.
"I know that football is not always logical and it is not always about strategies to get the results you would like.
"The problem is that we have become too accustomed to doing well. We have had the players with the ability to do extraordinary things.
"There comes a time where we need a little more patience, to follow some ideas and to have the time to evaluate them with the proper attention."
Andrea Caracciolo scored the only goal of the game in the 56th minute on Sunday as Novara completed the double over Inter this season.
They even held onto the win with just 10 men for the last 10 minutes of the game after Ivan Radovanovic was sent off.
Claudio Ranieri's side trail league leaders and arch-rivals AC Milan by 11 points with 15 games remaining, with second-placed Juventus only two points off the pace with two games in hand.
"Being happy after losing to San Siro seems obviously excessive," Moratti said. "But I have not lost faith in this team, these players and the coaching staff.
"And I still think that, because we still have important objectives - the league and the Champions League - there is no reason to give up.
"The season is very long and you give everything, especially in a year like this when it was always uphill."
He added: "Without looking at the past too much - because in football you should always think about the future - from June 2005 to May 2011 we have always won something.
"But I do not stop. I really want to start over. The real danger at this moment is that we become dominated by anxiety and rush to change everything."
