A more thorough explanation:

Definition: Nonobvious refers to an invention or idea that is not easily predictable or obvious to someone skilled in the relevant field. It means that the invention or idea is not something that anyone could have easily come up with just by looking at what already exists.

Example: A new type of smartphone that can project holographic images in 3D without the need for special glasses would be considered nonobvious. This is because it is not something that has been done before and would require a significant amount of innovation and technical expertise to develop.

Another example: A new type of car engine that runs on water instead of gasoline would also be considered nonobvious. This is because it is not something that has been done before and would require a significant amount of research and development to make it work.

These examples illustrate the concept of nonobviousness because they both involve inventions that are not easily predictable or obvious to someone skilled in the relevant field. They require a significant amount of innovation and technical expertise to develop, which is why they would be considered nonobvious.
