When is an Invention Obvious?
That being said, the possibility that a utility patent could be obtained cannot be definitively ruled out even if an invention seems quite likely to be obvious, which is one of the biggest problems with the law of obviousness. Indeed, one of the more frustrating things about working with the Patent Office is that there is a real lack of uniformity in application of the law of obviousness. For example, on January 7, 2014, the Patent Office granted U.S. Patent No. 8,622,700, which for all intents and purposes granted rights to the inventor to a glow in the dark ceiling fan blade. If this claim to a glow-in-the-dark ceiling fan blade is ever challenged I see no way that it could survive, but the patent issued.
