Couldn't this just be considered jury nullification? IANAL, but I don't think the responses in voir dire (especially to follow the instructions of the judge or the letter of the law) are any kind of binding promise. Won't the appeals judge just say, "too bad for you, Samsung, for asking the wrong questions and getting an unfavorable jury"?
No, jury nullification depends in a large part with the constitutional double indemnity clause. Basically if you are acquitted (found not guilty by a jury) you cannot be re-tried on that crime even if additional evidence comes up that points to you. So a jury 'nullifies' a law by acquitting you even if you were guilty, it prevents the law from punishing you for your acts.
If the jury gets it wrong and convicts you, then you can appeal for a new trial and try again.
