How are secondary considerations evaluated in design patent applications?

Secondary considerations, also known as objective evidence of nonobviousness, play an important role in evaluating design patent applications. The MPEP states: “Secondary considerations, such as commercial success and copying of the design by others, are relevant to the evaluation of obviousness of a design claim. Evidence of nonobviousness may be present at the time a…

What happens if there’s a lack of objective evidence of nonobviousness in a patent application?
