15. Examples 

The annex to this chapter gives examples of circumstances where an invention may be regarded as obvious or where it may involve an inventive step. It is important to stress that these examples are for illustrative purposes only and that the applicable principle in each case is: "was it obvious to a person skilled in the art?" (see G‑VII, 5). Examiners must not try to make a particular case fit into one of these examples if it is not clearly applicable. The list is also not exhaustive.
