Lee, the only son of Samsung Electronics Chairman Lee Kun-hee, has been invited by Apple's chief executive Tim Cook to the invitation-only memorial service for Jobs, according to sources close to the matter who declined to be named.
The event is scheduled for the evening of Oct. 16 at Stanford University's campus.
The Wall Street Journal reported earlier that Apple invited prominent Silicon Valley figures and others close to Jobs to the service. The private service will precede another event for Apple employees on Oct. 19 that will celebrate Jobs' life at the company's headquarters in Cupertino, Calif.
Jobs died on Oct. 5 after a long battle with pancreatic cancer.
The upcoming appearance of the Samsung scion at a memorial service for Apple's visionary leader stoked speculation that the two mobile rivals may hold a separate meeting that could end the fierce legal disputes that have raged for the past six months.
The rivalry and tension between the two companies reached its peak this month as they both refused to step back following a series of court rulings in Germany, Australia and the Netherlands.
Last month, a German court ruled in favor of Apple, imposing a temporary sales ban on Samsung's tablet computers for copying Apple's design. Samsung filed an appeal.
Last week, judges in Australia placed a sales injunction on Samsung's tablets, while the Dutch court rejected Samsung's request to ban sales of the iPhone and the iPad, dismissing its claim that Apple violated its mobile technologies.
Samsung and Apple are locked in more than 20 lawsuits in a dozen countries over mobile patents and designs, even though the maker of the iPhone is Samsung's biggest semiconductor customer.
The dispute started in April when Apple sued Samsung in the United States for "slavishly copying" its products.
Samsung then accused Apple of "free riding" on its mobile technologies and lodged lawsuits in Asia, the U.S. and Europe. It also filed motions in Italy and France to block sales of the iPhone 4S.
