DGLY has a strong case. Taser is really up s*it creek unless they settle. Cameras account for, what, 80% of Taser's new business? Taser has been trumpeting their automatic camera operation triggers, which are clearly covered by DGLY patents?
This one is going to get fun.
Taser will either have to settle or buy DGLY. The damages for Taser's infringement would destroy Taser.
