Most patent trolls send letters warning of dire consequences with an offer to settle. The settlement amount is purposely calculated to be "just below the cost of an effective defense". Few people challenge the trolls in court, and the trolls do their best to avoid going to court. They make their money from the ransom demands, not through lawsuites. It does not appear that any of this activity will show up in this study.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
