It seems like almost everyone is taking creative liberties with intellectual property these days. One of my favorite abuses of the system is the "patent troll." A normal person (or corporation) will obtain a patent to protect their own manufacturing or research interests. But a special subset of patent owners, known as "patent trolls", enforce patent rights against supposed infringement, even though they don't manufacture products or supply services related to the patent. Their entire business model is based on broad enforcement of intellectual property rights that they don't even use.
does it rub anyone else the wrong way that their system is "open source"?
at least they aren't charging royalties to use it.
