I've had an interest in free and open source software since high school. Through this interest, I learned about legal frameworks (mostly related to copyright), including software licensing (e.g., "copyleft" vs. "permissive"), litigation (e.g., SCO and USL v. BSDi), copyright term extension, and free culture.
From my limited knowledge, I think patents are a mixed bag. On one hand, I agree that they are a necessary incentive, but I also think they can be abused, particularly with "software" patents. I think "patent trolls" (see also, "When Patents Attack") and high-stakes lawsuits harm innovation.
In my senior year of high school, we wrote our own Supreme Court decisions for ongoing cases. I chose to write a decision (PDF) about Bilski v. Kappos, a case on patent eligibility.
I also was an active amateur radio operator for a while in high school, so I think wireless mobile technologies will be fun to learn and discuss.
I'm taking IEOR 190G in the hope that I'd satisfy my curiosity and gain a new, informed (engineering) perspective on patents.
