SAN JOSE, Calif. – After a year of scorched-earth litigation, a jury decided Friday that Samsung ripped off the innovative technology used by Apple to create its revolutionary iPhone and iPad.

The jury ordered Samsung to pay Apple $1.05 billion. An appeal is expected.

Apple Inc. filed its patent infringement lawsuit in April 2011 and engaged legions of the country’s highest-paid patent lawyers to demand $2.5 billion from its top smartphone competitor. Samsung Electronics Co. fired back with its own lawsuit seeking $399 million.

The verdict, however, belonged to Apple, as the jury rejected all Samsung’s claim against Apple. Jurors also decided against some of Apple’s claims involving the two dozen Samsung devices at issue, declining to award the full $2.5 billion Apple demanded.

However, the jury found that several Samsung products illegally used such Apple creations as the “bounce-back” feature when a user scrolls to an end image, and the ability to zoom text with a finger tap.

As part of its lawsuit, Apple also demanded that Samsung pull its most popular cellphones and computer tablets from the U.S. market. A judge was expected to make that ruling at a later time.

During closing arguments at the trial, Apple attorney Harold McElhinny claimed Samsung was having a “crisis of design” after the 2007 launch of the iPhone, and executives with the South Korean company were determined to illegally cash in on the success of the revolutionary device.

Samsung’s lawyers countered that it was simply and legally giving consumers what they want: Smartphones with big screens. They said Samsung didn’t violate any of Apple’s patents and further alleged innovations claimed by Apple were actually created by other companies.

Samsung has emerged as one of Apple’s biggest rivals and has overtaken Apple as the leading smartphone maker.

Samsung’s Galaxy phones run on Android, a mobile operating system that Google Inc. has given out for free.
