Many times, patent cases are argued like someone was trespassing: This idea is my property, and you started using it. What Apple did well in this trial is that it portrayed Samsung as a cheater—someone who looked over Apple's shoulder and copied down its answers. This portrayal obviously resonated with the jury leading to the overwhelming win.
Is that right? No, not really, especially for technical issues. Frankly, the most astounding part of this decision was that Samsung's standard-essential patents were not considered infringed. I fully expect Samsung to file (and win) a JNOV (a judgment notwithstanding the verdict) on that issue. But overall, I doubt this verdict will be overturned as a whole.
