::::::Samsung has gone on the offensive in its court battle
with Apple, accusing its rival of infringing patents
related to emailing photographs and 3G wireless
A Silicon Valley court gave was the Korean giant its
turn to throw mud in a high-stakes trial that has
gripped the industry.
Dr Woodward Yang, an electrical engineering
professor at Harvard, said Apple's products use
Samsung-patented features for mobile devices,
including the process for seamlessly emailing photos.
He was one of Samsung's first witnesses after a
parade of Apple experts said Samsung phones and
tablets violated Apple's patents.
One of Samsung's designers also testified that she
did not rely on Apple designs to create icons for
Samsung's Galaxy S smartphone line.
Apple and Samsung are going toe-to-toe in a patents
dispute mirroring a struggle for industry supremacy
between two rivals that control more than half of
worldwide smartphone sales.
The American company accuses Samsung of copying
the design and some features of its iPad and iPhone,
and is asking for a sales ban in addition to monetary
damages. The Korean company, which is trying to
expand in the United States, says Apple infringed
several patents, including some for its key wireless
Apple concluded presenting evidence regarding its
own patents this week, and Samsung started calling
witnesses. On Tuesday, Yang said Samsung's patents
were filed before the introduction of the iPhone in
Yang focused on patents that cover smartphone
features, not wireless technology. One of those
patents covers technology for easily finding photos in
an album.
"The idea here was, let's have a bookmark," Yang
Under questioning from Apple attorney Bill Lee, Yang
acknowledged he had not seen evidence that
Samsung actually used any of those features in its
own smartphones.
Later on Tuesday, Samsung called designer Jeeyuen
Wang, who said she and a large Korean team worked
hard for three months to create Samsung's own icon
designs for Galaxy S phones.
"I slept perhaps two hours, or three hours a night,"
Wang said.
Apple attorney Michael Jacobs showed Wang internal
Samsung documents - with her name on them -
containing references to Apple icons. However, under
questioning from Samsung attorney John Quinn,
Wang said some of those documents were created
well after Samsung had finished its own designs.
In an attempt to invalidate some of Apple's patents in
the case, Samsung also presented evidence this
week to show that Apple's patents cover
technological advances - like multitouch - that had
already been developed before Apple claims to have
invented it.
