FORTUNE — Susan Kare, the designer who created much of the look and feel of the original Macintosh, took the stand Tuesday as a paid Apple (AAPL) witness in the company’s multibillion patent infringement suit against Samsung.
She was shown the slide at right, a comparison between a screenful of iPhone icons and a similar screen from the Samsung Galaxy S1, along with directions for how Samsung’s designers could use Apple’s work to improve theirs. (Examples: “use highly intuitive icons” and “change long names to simple ones.”)
If that slide weren’t enough to persuade the jury that Samsung was deliberately copying Apple’s “trade dress” — a legal term of art for the patentable appearance of a product — Apple had plenty more where that came from. One hundred and twenty six slides in all that show Samsung doing the same thing for just about every aspect of iPhone’s user interface, from the grid on the home screen to the way a map can be peeled back to show more menu options in the Maps app.
They were part of a “Relative Evaluation Report” Samsung created in March 2010 after the launch of the Galaxy S and before the launch of the Galaxy SII and SIII.
Samsung fought hard to keep the report out of the jury’s hands. On Tuesday, Apple managed to enter into evidence an English translation (along with the original Korean) marked Plaintiff’s Exhibit No. 44.
