This is good news in that I generally feel any setback for an apparent patent troll is a good thing.
But this isn't too broad. Looks like a very specific issue to this trial... not even this patent claim or case, let alone a broader implication for patent claims in general.
It sounds like VirnetX's lawyers simply referenced a previous case too often in the judge's estimation, and so he's throwing the verdict out, meaning a retrial would be necessary. Case doesn't seem to set any precedent (or, what precedent it does set on referencing previous trials might cut both ways for patent plaintiffs and defendants). Noting regarding merits of claims or anything as far as I can tell from the reporting.
If anyone more expert can weigh in or correct, that'd be appreciated too!
