FORTUNE -- Samsung's Galaxy Tab 10.1 -- a tablet that copied Apple's (aapl) iPad so slavishly that more than one judge had trouble telling them apart -- has become something of a legal football.
In June, Judge Lucy Koh granted a preliminary injunction blocking Samsung from selling the phone in the U.S.
"Although Samsung has a right to compete," she wrote in a ruling that must have been music to Apple's ears, "it does not have a right to compete unfairly, by flooding the market with infringing products."
Then in August the Apple v. Samsung jury that gave Apple nearly everything it asked for -- including damages of $1.05 billion -- ruled that the Tab DID NOT infringe Apple's design patents.
Samsung promptly asked that the preliminary injunction be lifted. Judge Koh kicked the decision up to the appeals court. The appeals court kicked it back to her. And on Monday, Judge Koh granted Samsung's motion, prompting a flood of "Samsung Wins" headlines and a press statement claiming vindication from Samsung.
But the Galaxy Tab is not out of the woods yet.
Given that Judge Koh had found Tab "virtually indistinguishable" from the iPad, and having read post-verdict remarks of a juror that suggested the jury's ruling was based on a misunderstanding of patent law, (see Did the jury blow the Galaxy Tab verdict?), Apple filed a so-called Rule 50 motion asking Judge Koh to overrule the jury.
Rule 50 allows a judge to issue a directed verdict when the evidence permits only one reasonable conclusion -- a conclusion different from the one the jury reached.
Directed verdicts are relatively uncommon, according to Christopher Carani, a design law expert at McAndrews Held & Malloy. But in this case, he says, "Apple's argument may have some traction and Judge Koh may well exercise this super-charged trump card in Apple's favor."
A hearing on Apple's motion is scheduled for Dec. 6. Meanwhile, Judge Koh is holding on to a $2.6 million bond Apple would have to forfeit to Samsung should it lose its last shot.
