Apple is pointing to an internal Samsung document highlighting the weaknesses of the Galaxy S1 compared with the iPhone as further evidence that Samsung has copied its work.

The document, a "relative evaluation report" on the Galaxy S1 and iPhone published in March 2010, highlights where Samsung's flagship phone fell short of the iPhone. The report looked at several different features, from the call screen to the browsing experience and even the difference in the calculator.

Apple will draw on this document as proof that Samsung actively compared its products against the iPhone, and made strides to better mimic the blockbuster device. Samsung, however, would argue that it does opposition research against all of its major rivals.
