Patents, Novelty, and Trolls: Crash Course Intellectual Property #4

本星期, Stan teaches you about patents. It turns out, they’re patently complicated! 所以, patents have some similarity to copyright, in that they grant a limited monopoly to people who invent things. The key difference in patents and copyright is that patents are for THINGS. Copyright is for an idea. 所以, if you’ve come up with a great new invention, like for example, a condiment gun, you should get a patent. We’ll also talk about some of the limitations and problems of patents, including patent trolls
