Apple vs. Samsung: Experts Defend Patent Rights

Apple's well-paid experts told a federal jury Monday that Samsung has violated key patents on the iPhone and iPad, as their trial over rights to smartphone and tablet technology moved into its second week.

During a day of dry, technical testimony, two Apple experts said they had reviewed technology in Samsung's smartphones and tablets, and concluded it infringed on three of the five Apple patents at issue in the trial -- the universal search, data synchronization and data-recognition features in iPhones and iPads.

Todd Mowry, a Carnegie Mellon University computer science professor, acknowledged he's been paid about $350,000 so far for his expert work for Apple, while the other expert witness, Alex Snoeren, a UC San Diego computer science professor, has received about $200,000.

Samsung's lawyers tried to undercut their testimony with questions suggesting there are distinctions in how the patented features work in Apple and Samsung devices, and that simple similarities are not enough for patent infringement.

The testimony came in the second trial between Apple and Samsung, which are waging a global legal feud over allegations that Samsung's smartphones and tablets copied patented features in the iPhone and iPad. Apple has asked the jury to award more than $2 billion in damages.

After the first trial in 2012, which resulted in a nearly $1 billion damages award against Samsung for its older line of products, jurors indicated they did not put much stock in the competing testimony of Apple and Samsung experts. But both sides are again relying heavily on such expert testimony in the current trial, which involves more recent smartphones and tablets.

Apple's damages experts are expected to take the stand at some point Tuesday.
