Apple and Samsung Electronics have reportedly held several private negotiations to settle ongoing patent disputes.
Citing legal documents and people familiar with the matter, the Wall Street Journal reported that both the firms had face-to-face meetings in Seoul, South Korea in December last year, reaching closer to a deal in February before the talks stopped.
However, the Journal reported that talks, which continued until March, appeared to have broken down soon afterwards.
Samsung was also reported to have urged Apple to reopen negotiations, a proposal the ITC document indicates Apple hadn’t yet responded to by the time of the decision.
In August 2012, Samsung was ordered to pay Apple $1.05bn in damages but earlier this year US District Judge, Lucy Koh, cut about $450.5m from the price tag.
Apple and Samsung, which collectively make about half the smartphones sold across the world, are involved in about 30 lawsuits in four continents.
Both the companies scored victories in their patent battles in different countries since the iPhone maker accused the South Korean firm of infringing its devices.
Last month, a US judge rejected Apple’s request to add Samsung Electronics’ Galaxy S4 smartphone to the list of products, which it claims to infringe its patents.
A recent report from StatCounter has revealed that the number of users globally connected to the net via Samsung’s devices had surpassed those of Apple devices in June 2013.
