Apple v. Samsung: Expert Witnesses Weigh In

April 17, 2014

Multiple expert witnesses testified this week that Samsung did not infringe on Apple’s patents for “quick links, universal search, slide-to-unlock, and auto-correct. Kevin Jeffay, computer science professor, argued that Apple’s “647 quick-links patent is more limited than the company claims.” Quick-links allows data that can be clicked to be automatically detected. Mr. Jeffay said he does not believe Samsung has infringed that patent after pointing out that Apple’s patent uses an “analyzer server” and Samsung devices do not; this process (on Samsung devices) is performed by the application itself.

Another computer science professor, Martin Rinard, testified that after careful analysis he concluded that Samsung did not infringe Apple’s universal search patent. Furthermore, Saul Greenberg, a professor at the University of Calgary, “testified that slides are common in most user interfaces and Samsung did not copy Apple’s slide-to-unlock technology.”

Not only did the experts testify that Samsung did not infringe on Apple’s patents, they went further and testified that there was no evident commercial success that resulted from those supposed infringements. The experts said there is lack of proof that people bought iPhones because of the slide-to-unlock feature. In addition the experts believe that Apple’s patents are not valid, Martin Rinard said “the patent office didn’t have the information in front of it to make the right decision [when it granted Apple a patent for universal search].”

Samsung also questioned another expert witness, Daniel Wigdor, on the “validity of Apple’s ‘172 patent for predictive text.” Mr. Wigdor told the court that other companies had developed that auto-correct feature before Apple filed a patent for it.

Both Samsung and Apple are back at the same courthouse less than two years later fighting over patent infringements. Although millions are at stake, it seems that the more important feat is dominance over the smartphone market.

Stay tuned for what happens next, court resumes tomorrow.
