Final answer:
Combining a camera with a cell phone in a smartphone passes the test for non-obviousness due to technological advancement and creativity, while putting wheels from a chair onto an office cart would not pass the test.
Step-by-step explanation:
Combining a camera with a cell phone in a smartphone passes the test for non-obviousness because it involves a technological advancement. This combination of two separate devices into one was not obvious at the time of its invention and required innovation and creativity. On the other hand, putting wheels from a chair onto an office cart would not pass the non-obviousness test because it lacks technological advancement and creativity. It is a simple combination of existing components without any significant improvement or change in functionality.
