Judge Koh has made some pre-trial rulings that are favorable to Apple. One prevents Samsung from discussing certain patents that faced reexamination. It does make Samsung's challenge here more daunting than usual since the jury will know that these particular models already were identified by the first jury as having infringed on an Apple patent. The new jury's job is to determine damages only. This trial has nothing to do with the next Apple v. Samsung patent trial scheduled for February. And Judge Koh will behind the bench for that battle as well.
The first jury awarded Apple $1.05 billion which was reduced to $555 million with a flick of Koh's pen. After the damages trial, the amount owed by Samsung to its rival could be back above that billion dollar mark.
