The Gadget

SAN JOSE, Calif. -- Additional internal Samsung documents suggesting that the company looked to Apple for examples of how to enhance the features of its mobile devices were made public today.

During the testimony of Ravin Balakrishnan, a professor in the department of computer science at the University of Toronto, Apple brought out two of Samsung's internal usability studies -- one for a smartphone (see the first embedded document below, "Behold3 Usability Evaluation Results") and another for a tablet (see the second doc below, "P5 Usability Evaluation Results") -- with direct instructions to mimic Apple's software features.

One study dealt directly with Samsung's Vibrant smartphone, then code-named the Behold 3. The other focused on a preproduction model of Samsung's Galaxy Tab device, with comparisons to Apple's iPad 2. Both reference a particular gesture behavior, a "bounce back" effect, something outlined in Apple's '381 patent. In its complaint, Apple has accused Samsung of directly infringing on it.

In his testimony, Balakrishnan said that was, in fact, the case with 21 of Samsung's devices.
