What is the “Art Recognized Suitability for an Intended Purpose” doctrine in patent law?
The “Art Recognized Suitability for an Intended Purpose” doctrine is a legal principle in patent law that relates to the obviousness of an invention. It states that selecting a known material or component for its recognized suitability for an intended use can support a prima facie case of obviousness.
As stated in MPEP 2144.07:
“The selection of a known material based on its suitability for its intended use supported a prima facie obviousness determination” in the landmark case of Sinclair & Carroll Co. v. Interchemical Corp.
This doctrine suggests that if a person of ordinary skill in the art would recognize a material or component as suitable for a particular purpose, using that material or component for that purpose may be considered obvious and thus potentially unpatentable.
