Aug. 10 (Bloomberg) -- A witness for Apple Inc. testified that 21 Samsung Electronics Co. smartphones copy patented technology for "rubberbanding," the way an iPad or iPhone screen seems to bounce when a user scrolls to the end of a file.
Ravin Balakrishnan, a University of Toronto professor hired as an expert witness, told the jury today at the companies' intellectual property trial that Apple's innovation was designed to tell users "you've reached the edge, the system is still alive, and it's not frozen."
Another Apple patent for technology that allows users to pinch, expand and re-size images on a screen is infringed by 24 Samsung products, Karan Singh, Balakrishnan's colleague at the university, testified in federal court in San Jose, California. He also said Samsung smartphones infringe Apple's patent for "repositioning and rightsizing" images on screens.
The rightsizing technology lets users re-size, enlarge and reposition articles in an online newspaper, for example, to "make that piece of information available," he said.
Apple and Samsung are the world's largest makers of the high-end handheld devices that blend the functionality of a phone and a computer. The trial is the first before a U.S. jury in a battle being waged on four continents for dominance in a smartphone market valued by Bloomberg Industries at $219.1 billion. Each company is trying to convince jurors that its rival infringed patents covering designs and technology.
The case is Apple Inc. v. Samsung Electronics Co. Ltd., 11- cv-01846, U.S. District Court, Northern District of California (San Jose).
