Apple has won the latest round in its nine-year patent mega-battle with VirnetX – with a US appeals court rejecting a $600m jury decision and sending it back down to the district court to redecide.

The victory saw Apple’s share price go up by more than one per cent but, in an indication of their comparative sizes, VirnetX’s share price collapsed by 50 per cent on news of the decision [PDF] on Friday. As everyone has had time to digest the decision, however, VirnetX’s share price has partially recovered – in large part because Apple is still on the hook for most of the $600m award.
