Apple attorneys
told a federal judge that they expect to wrap up their presentation on Aug. 13
in the $2.5 billion patent lawsuit against Samsung for copying Apple’s designs
for iPhone and iPad devices in Samsung’s smartphone and tablet products.

Testimony in the case on Aug. 10 focused on features in an iPhone that Apples claims were copied in a Samsung product.
Computer scientist Raven Balakrishnan of the University of Toronto testified on
behalf of Apple about the “rubber band” effect in the iPhone user interface.
This is an effect that the user observes when scrolling down the home screen with
its full display of application icons. When the user reaches the bottom of the
screen, the image seems to bounce back a bit.

Under questioning by Apple attorney Michael Jacobs, Balakrishnan said he examined several Samsung
phones and their underlying computer code and concluded that 21 Samsung models
infringed on the Apple patent regarding the rubber band effect.

But under cross-examination by Samsung counsel Kevin Johnson, Balakrishnan acknowledged
that Samsung could have created the rubber band effect without infringing on
Apple’s patents.

Another University of Toronto computer science professor, Karan Singh, testified about
a Samsung feature that enables users to zoom in and out of an image by touching the screen and
pinching or expanding their fingers. Singh said 24 Samsung devices offer
that feature, in violation of Apple patents.

Late in the day on Aug. 10, Boris Teksler, the director
of patent licensing strategy at Apple testified that “We were shocked” when
Samsung introduced a smartphone that looked so much like the iPhone. He said
then-CEO Steve Jobs and then-chief operating officer Tim Cook complained
directly to Samsung. Cook later succeeded Jobs as CEO Two months before Jobs
died in October of 2011.

The testimony about the rubber band effect and finger gestures is consistent with other evidence Apple has
presented during the trial held in U.S. District Court for the Northern District of California in San Jose. Apple has presented evidence to support
its claim that Samsung didn’t just study features of the iPhone and iPad, but directly copied those
features in developing its competing products.

Notably, Philip Schiller, the senior vice president of worldwide marketing at Apple, and the highest ranking Apple
executive to appear so far, testified earlier that Samsung "has ripped off a number of
our design elements," which he added has hurt sales of iPhones and iPads
and confused consumers in the smartphone market.

Apple also introduced an internal Samsung document from 2011 chronicling more than 100
side-by-side comparisons of an iPhone and a Samsung phone in development that
noted the shortcomings of the Samsung smartphones versus the iPhone.

In its defense, Samsung witnesses have testified that they looked at iPhone and other brands of
smartphones in developing their products, which is common practice, but said
that does not mean that it copied patented features.

In fact, Scott Forstall, Apple’s senior vice president in charge of the iOS software for iPads
and iPhones, testified that Apple also did "teardowns" of competitors’ products, but said that
was to benchmark rival designs, not to copy them.
