Thanks for the deep procedural history, I appreciate it.
So long story short, correct me if I'm wrong, there are claims that have been found infringed by the district court, and reviews of those claims are still pending before the PTAB after a remand from the CAFC. Is that a decent summary?
If so, isn't ideal circumstances to ask the court to wait on entering a final judgment until the PTAB finishes it's thing? It can't be that long since they're past the institution phase.
At the very least, Apple might need to put up bond to put off enforcement until the PTAB is finished.
Also, I'm not sure what you said is correct. Even if final judgment is entered, but the claims are ultimately found invalid by the PTAB and all appeals exhausted, I don't think VitnetX is entitled to damages still. The judgment would be vacated.
You've got to hand it to VirnetX. Very few go all the way with Apple like this and comes out ahead.
Apple's doesn't always fight fair.
You're welcome.
Yes, Apple has been found to have infringed claims from two VirnetX patents by the district court as affirmed by the Federal Circuit.
In separate proceedings, the PTAB is reconsidering whether those claims (and others) are invalid.
As for the Federal Circuit waiting, Apple no doubt would have liked both the district court and the Federal Circuit to wait for a final decision from the PTAB. Apple commented in a recent Supreme Court cert petition (relating to an earlier case between VirnetX and Apple) that it was unusual that the district court didn't stay that litigation pending a final decision from the PTAB.
In response to your penultimate paragraph, that will depend on a couple things. First, the timing of the respective final judgments - i.e. the one from the infringement case and the one from the IPR. Second, what the Supreme Court decides to do with the cert petition I mentioned above and, if it grants cert, how it rules on the questions raised.
Generally speaking, if a patent is invalidated by the PTO that invalidation has effect in pending infringement cases. The question is, when is an infringement case no longer pending? An invalidation doesn't negate the damages awarded in an infringement case if that case is not on-going.
The infringement case we've been talking about in this thread is the second brought by VirnetX against Apple based on the 4 patents I mentioned. This second case is based on alleged infringement by a newer version of iOS. The earlier case alleged infringement by an earlier version and by earlier devices. VirnetX won that earlier case also, with the finding that Apple had infringed all 4 patents being upheld by the Federal Circuit. In the second case, the Federal Circuit upheld the infringement finding for only 2 of the patents.
The Federal Circuit already upheld the PTAB's invalidation of those 2 patents found to have been infringed in the earlier case but not in the latest case. But here's where the issue of timing comes in. The Federal Circuit upheld that invalidation after it had upheld the infringement findings from the earlier district court case - i.e., after it had upheld the infringement finding for those same 2 patents.
The timing went like this: A Federal Circuit panel upholds infringement finding. Apple asks the Federal Circuit to rehear the case en banc. A Federal Circuit panel upholds the PTAB's invalidity finding (according to Apple this happened before the mandate, which effectively ended the infringement case at the circuit court level, was issued). Apple requests leave to file a second petition asking the Federal Circuit to reconsider the case, arguing that the invalidity of 2 of the patents should require the damages award to be reconsidered. The Federal Circuit denies Apple that leave.
Apple has now filed a cert petition with the Supreme Court, that petition is set to be heard during the Court's conference next Friday. One of the arguments Apple is making is that the Federal Circuit erred by not giving effect to the invalidity finding which Apple argues came while the infringement case was still pending. Apple argues that it was still pending because the appellate mandate hadn't issued and because it hadn't yet filed a cert petition with the Supreme Court, let alone had that petition denied.
If the Supreme Court grants Apple's petition with regard to this timing issue (Apple also raised an apportionment question in its petition), then we may well get further clarity on when PTAB invalidations are to be given effect in infringement cases. But even if the Court were to find in Apple's favor on this issue, that might not help Apple when it comes to the second infringement case. That case is on track to be finally resolved - e.g., by a Supreme Court cert denial - before a PTAB invalidation of the other 2 patents (if that's what the PTAB does on reconsideration) could be issued and upheld.
Who knows what will happen, but I think there's at least a reasonable chance that the second infringement case won't still be pending if and when those 2 patents are ultimately invalidated.
