Verdicts in complex patent litigation cases usually take 2+ days. Large, complex cases can take a week or more during which they can ask for advice from the judge or review of the evidence. Some juries split into sub-groups to study specific aspects of the determination such as laying out of the claims and specifics of infringement. The details of recent cases can be looked up to get an idea of how this might work. What often happens is a few jury members help organize/chair the process. In this case one jury member who is a lawyer and another an engineer, so it might be guessed they will play the role of helping to lead the deliberations.
This is often where the weight of the trial comes down on the jurists, some who probably want this to end quickly. However, the judge has to compel the jury to get the details right: In Apple vs. Samsung's recent case the individual patents were detailed with assessment of damages attributed to each. Samsung used what they claimed as incongruities as part of their appeal of the ruling of infringement. So, while the longs may hope for a quick ruling, the odds weigh against it.
