>"The government can't just take property from someone, they have to pay for it."<p>This made me laugh pretty hard.<p>Licensing a "concept" is ridiculous and I don't know how people can get away with it. Suppose we came up with a very abstract definition of what constitutes a table, and the next time a company wants to design one they owe the inventor of the table a fee. Would that put it in perspective just how ridiculous patent trolls are?<p>Arrival star made a device that keeps track of schedules. I can understand patenting their specific hardware, designs, etc..., but how can they claim that they invented the concept of scheduling, let alone that it is so unique that they are able to mark it as theirs?<p>Hey, Arrival Star, it's called competition. If someone makes a similar device (without "stealing" your exact designs), don't cry about it. You need to one-up them or find a cheaper way to do it.
