Smartphones: Patent wars set to continue

Many patent battles continue to rage between technology companies over smartphone designs. Yet in the US, and around the world, few have resulted in significant device bans or damage payments. There is little evidence that the patent wars have slowed the pace of innovation, experts say. Yet for now at least, the legal campaigns largely continue in the hope of an injunction that would block a competitor’s flagship handset from sale, or a royalty agreement to avert such a move.
