SAN JOSE: The mammoth Apple-Samsung patent trial moved to the jury Tuesday, setting the stage for a verdict that could have huge implications for the hot market in smartphones and tablet computers.

US District Judge Lucy Koh began reading instructions to the nine-member jury in San Jose, California, as lawyers for the two tech giants readied closing arguments.

Apple, which accuses the South Korean electronics giant of copying the iPhone and iPad too closely, is seeking damages of up to $2.75 billion and an injunction that could knock some Samsung products off the US market.

Even a delay in sales could endanger Samsung’s position in the US market, where it is currently the top seller of smartphones.

Samsung has countered by arguing that its patents on wireless communication were infringed by Apple, and is demanding up to $422 million from the Silicon Valley manufacturer.

The trial is wrapping up after 10 days of testimony over three weeks, in which Apple put its own designers and executives on the stand, along with experts, all of whom accused Samsung of illegally copying Apple designs.

Samsung witnesses said meanwhile that they had come up with the designs and icons they used on their own.

However, internal Samsung documents introduced as evidence did show they were aware that they were behind Apple’s iPhone when it came to some user-interface features.

One Samsung designer described the gap between the iPhone and a Samsung smartphone as the “difference between Heaven and Earth.”

The case has been a particularly heated one, with lawyers from both sides filing hundreds of pages of objections against particular exhibits and witnesses.

At one point, Koh asked an Apple lawyer if he was “smoking crack” when he proposed to put more than 20 witnesses on the stand in the final day of testimony.

“First of all, I’m not smoking crack, your honor,” replied Apple lawyer Bill Lee.

The jury was expected to begin deliberations in the case on Wednesday, and will have to pore over a complicated 20-page form addressing hundreds of separate allegations, that Samsung violated Apple’s patents and trademarks.

Last week, Koh asked for one more settlement conference, with the chief executives of the two companies speaking directly by telephone.

“I see risk for both sides,” Koh said at that time. “It’s time for peace.”On Monday a Samsung lawyer confirmed that Apple chief Tim Cook and Samsung boss Kwon Oh-Hyun did talk but no settlement was reached.

This is one of several court cases around the world involving the two electronics giants in the hottest part of the tech sector — tablet computers and smartphones.

While the results so far have been mixed in courts in Europe and Australia, Samsung has a lot at stake in the US case, which could result in large damages or injunctions against its products in the American market.

A survey by research firm IDC showed Samsung shipped 50.2 million smartphones globally in the April-June period, while Apple sold 26 million iPhones. IDC said Samsung held 32.6 per cent of the market to 16.9 per cent for Apple.

Samsung is the leading maker of smartphones using Google’s Android operating system, which has become the most popular platform despite complaints from Apple that it has infringed on its patents.
