What does “unobvious” mean in patent law?
There is a lot of ambiguity about what “unobvious” means in the context of U.S. patent law. The level of unobviousness required to render an invention patentable is a function of the particular art area containing the invention. In some cases the unobvious part of an invention (the part that renders the invention patentable) is simply identifying the problem, even if the solution is obvious once the problem has been identified.
