A court in Tokyo has ruled that several older Samsung smartphones violate an Apple "rubber-banding" patent, Reuters reports. The patent describes the way an iOS window bounces once a person has reached the end of a scrolling page. Samsung has sidestepped the patent with recent devices, changing its implementation of Android to only show a blue line at the end of a page, but the company could still potentially face damage payments and product injunctions. The court is expected to provide more details when it hands down a final ruling later today.
