Ask HN: I have to do a 12 minute presentations on Patents

I have an upcoming presentation that I have to do on Patents and the topic is in Physics, its a group presentation but I managed to luck out and convince the professor to do it single. So 12 minutes is long, what do you guys think would be a good way to present everything about patents for a group of undergrad physics students? I want to do a good job at this, I have thought have using a kahzoo or a game and an question or answering period at the end. But I am not a lawyer.
