There's no sense wasting time: Apple has posted that bond. In turn, Samsung has filed a motion to stay the injunction pending its appeal, and Apple has been given until Saturday, June 30, 9:00 a.m. PT to file its opposition brief.

This is, of course, just the latest salvo in the patent war between Apple and Android OEMs. Just a few days ago, Apple suffered a defeat when a patent base between itself and Motorola was dismissed.
