The commission now expects to take a decision on 4 June
The US International Trade Commission (ITC) has extended its deadline to determine on whether Apple infringes patents owned by Samsung Electronics in iPhone, iPad and iPod Touch.
The commission, which was due to make a final ruling on 31 May, now expects to take a decision on 4 June.
In June 2011, Samsung first sought for a ban of Apple’s allegedly infringing products, claiming most of its devices were being copied by the iPhone, iPad and iPod touch.
In September last year, an ITC judge said in a preliminary ruling that Apple did not violate the patents of Samsung.
Earlier this year, US ITC judge Thomas Pender said in a preliminary decision that Samsung has infringed an Apple patent by incorporating the text-selection feature in its devices.
However, Pender said the South Korean firm did not infringe portions of a second Apple patent which enables a device to identify if a microphone or other device is plugged into its microphone jack.
Apple and Samsung, which collectively make about half the smartphones sold across the world, are involved in about 30 lawsuits in four continents.
