Can prior art from a different field be considered analogous art?
Yes, prior art from a different field can be considered analogous art if it meets certain criteria. According to MPEP 2141.01(a):
“A reference is analogous art to the claimed invention if: (1) the reference is from the same field of endeavor as the claimed invention (even if it addresses a different problem); or (2) the reference is reasonably pertinent to the problem faced by the inventor (even if it is not in the same field of endeavor as the claimed invention).”
This means that even if a prior art reference is from a different field, it can still be considered analogous art if it is reasonably pertinent to the problem the inventor was trying to solve. The key is to consider whether a person of ordinary skill in the art would have looked to that reference to solve the problem at hand.
For example, a reference from the field of electrical engineering might be considered analogous art for a mechanical engineering invention if it addresses a similar problem or uses relevant principles that could be applied to the invention.
