Hyong Shin Park a Samsung Electronics company designer and one of the inventors of Samsung’s F700 phone has been barred by a federal judge from testifying in the on-going multibillion- dollar patent trial between Apple and Samsung over mobile devices.

The U.S. District Judge Lucy Koh in federal court in San Jose, California stated that the designer cannot testify in Apple/Samsung patent trial as she didn’t design any of the devices at issue in the case and her testimony is of limited value in evaluating Apple’s design patents in suit and Samsung sought to use Park’s testimony to establish functionality of the F700 design and to rebut allegations of copying or wilfulness, Koh said in her ruling..

Judge Lucy also added that “The risk of undue prejudice to Apple outweighs the probative value of Ms. Park’s testimony,”

The first of this kind of trial placed before a U.S. jury between U.S. Company Apple Inc. suing South Korea based electronic company Samsung in battle of dominance in the smartphone market in over four continents which has been valued at $219.1 billion according business website Bloomberg.
