A U.S. jury has awarded a victory to U.S. technology giant Apple, saying that its South Korean rival Samsung Electronics infringed on its patents for mobile devices.

The jury in the state of California awarded Apple more than a billion dollars in damages.

Apple claimed that Samsung illegally copied designs of its popular iPhone and iPad devices and used them to create its own line of Galaxy devices.

Samsung had argued that by 2006 — months before Apple introduced its first iPhone in early 2007 — it was developing a next generation of smartphones with a rounded rectangular body that both companies now use.

The case is part of a multibillion dollar global legal battle between the two technology powerhouses.

Earlier Friday, a South Korean court ruled that both Apple and Samsung infringed on the others' patents.

The Seoul court said that Apple infringed on two Samsung wireless patents, while Samsung violated one of Apple's design patents. It awarded small damages to each side and imposed a limited ban on the sale of each company's products in South Korea.
