The lawsuit was filed in 2011 by seven consumers.
Apple has asked a US federal judge to dismiss a consumer lawsuit filed in 2011 alleging that the company illegally monopolised the iPhone's aftermarket applications.
According to Bloomberg, attorneys filed the suit claiming that a monopoly existed because an iPhone user who doesn't want to pay what developers charge for applications in Apple's App Store can't go anywhere else to buy them.
Attorneys also claim that iPhone software developers are required to turn over more than 30% of what they charge for an application, while increasing prices and excluding competitors from the iPhone aftermarket of applications.
According to Bloomberg, Apple's attorney, Dan Wall's said the court hearing which said the company doesn't set the price for paid applications and charge a price for distribution of a product on a new and unique platform, doesn't violate any antitrust laws.
"There's nothing illegal about creating a system that is closed in a sense," Wall said.
Alexander Schmidt, an attorney representing seven consumers who sued Apple, said: "Can a consumer go somewhere else to buy Angry Birds for the iPhone?. If the answer is no, then Apple is a monopolist."
Prior to the iPhone monopoly lawsuit, Apple has also been accused of maintaining a music-downloading monopoly.
