Late last August, a jury awarded Apple with damages amounting to just over $1 billion, saying that Samsung infringed upon Apple's patents. Just this March, Judge Lucy Koh struck $450 million from those damages saying that the jury didn't fully understand the patent issues.
A new court date has been set for November 12, at which time Samsung and Apple will go at it again to argue damages. All of the evidence for this trial will be limited to that which was shown in the original court battle. Samsung could end up having to pay less, but they could also end up being on the hook for more, though it shouldn't go above the original $1 billion awarded.
A further court battle will occur in March 2014 over additional patent infringement claims. Why can't we just be friends?
