Obviousness is King

I have posted the link below to "Obviousness is King" video. He explains how obviousness is a legal test and what must be done for a patent to be accepted and considered legal. He explains that this will often time take the longest time as the examiner must judge if there is enough innovation in the new invention. As we can see, the word enough can be interpreted in different ways. As subjectivity comes into play here, one must refer to someone of ordinary skill in the art. It still remains that due to the subjectivity, deciding whether or not a patent is obviousness can become very tricky and take quite some time.

For some reason, it did not allow me to embed this video. The link is below.
