With billions at stake, here are the weirdest moments in Oracle's massive lawsuit against Google

The two were back in court this week, with an all-star list of witnesses.

At issue is Google's use of 37 application programming interfaces in its Android software that came from a programming language called Java that's owned by Oracle.

The software industry is in a tizzy over this case because if Oracle wins and Google has to pay up, it could set off an explosion of lawsuits in the industry.

The trial has been going on for years, across three phases. The jury is currently deliberating.

No matter what the jury decides, the loser will likely file an appeal.

In the meantime, many stars of the tech world were called to the stand and a lot of memorable things happened.

Here's a look at some of those highlights, as well as an overview of what this case is about.
