On a warm summer’s afternoon two years ago, a group of jurors secretly exited a San Jose courthouse, avoiding a swarm of reporters and news cameras. They had just reached a verdict on what was dubbed by some as “the patent trial of the century,” a fight between Apple and Samsung that was ultimately over the idea of originality.

After a three week-long trial that included more than 50 hours of testimony and arguments from both sides, Apple handily beat Samsung, convincing the jurors that Samsung not only copied its technology, but also made billions in the process. Yet, the aftermath of it all didn’t live up to the dramatic ruling.

Apple was awarded just over $1 billion in damages, though that figure was later cut down to $939.8 million after the judge pointed out errors in the way the jury did its math. Those damages were retried, and came in lower than the original figure, though the entire amount has since been appealed, and Samsung hasn’t paid a penny. Alongside that, Apple and Samsung failed to win bans against one another’s products in the US, making the first trial seem like nothing more than a legal spectacle.

But in the midst of all that was a very real threat: another lawsuit, one that targeted more successful devices from both companies, and used easy-to-understand patents covering basic software features. Apple filed it against Samsung in February 2012, targeting 17 devices. Samsung responded in kind, and this week the pair go head to head once again; the outcome could be very different. Here’s what to expect over the next weeks and months as these two titans clash again in California’s courts.
