How does the concept of “teaching away” apply in patent obviousness cases?
“Teaching away” is a concept in patent law that can be used to rebut a prima facie case of obviousness. According to MPEP 2144.05: “A prima facie case of obviousness may also be rebutted by showing that the art, in any material respect, teaches away from the claimed invention.” Teaching away occurs when a person…

What is the significance of ‘critical’ or ‘optimum’ ranges in patent claims? ‘Critical’ or ‘optimum’ ranges in patent claims are significant because they can potentially overcome a prima facie case of obviousness. According to MPEP 2144.05: “The applicant must show that the particular range is critical, generally by showing that the claimed range achieves unexpected…
Read MoreWhat is the significance of ‘about’ in patent claims involving ranges?
What is the significance of ‘about’ in patent claims involving ranges? The term ‘about’ in patent claims involving ranges is significant because it can affect the interpretation of the claimed range and its obviousness analysis. According to MPEP 2144.05: “The use of ‘about’ avoids a strict numerical boundary to the specified parameter.” This means that…
Read MoreWhat is routine optimization in patent law?
Routine optimization refers to the process of finding optimal or workable ranges through routine experimentation. According to MPEP 2144.05: “[W]here the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation.” This principle is based on the case In re…
Read MoreWhat is a result-effective variable in patent law?
A result-effective variable is a parameter that is recognized in the prior art as affecting a particular result or outcome. The concept is important in patent law, particularly in obviousness determinations. According to MPEP 2144.05: “A recognition in the prior art that a property is affected by the variable is sufficient to find the variable…
Read MoreHow can an applicant rebut a prima facie case of obviousness for overlapping ranges?
An applicant can rebut a prima facie case of obviousness for overlapping ranges in several ways, as outlined in MPEP 2144.05: Showing criticality of the range: The applicant must demonstrate that the claimed range is critical, generally by showing unexpected results relative to the prior art range. Teaching away: The applicant can show that the…
Read MoreHow does the breadth of a prior art range affect obviousness determinations?
The breadth of a prior art range can significantly impact obviousness determinations in patent law. According to MPEP 2144.05: “One factor that may weigh against maintaining an obviousness rejection based on optimization of a variable disclosed in a range in the prior art is where an applicant establishes that the prior art disclosure of the…
Read MoreWhat is the legal standard for obviousness of overlapping ranges?
According to MPEP 2144.05, “In the case where the claimed ranges ‘overlap or lie inside ranges disclosed by the prior art’ a prima facie case of obviousness exists.” This principle is based on several court decisions, including In re Wertheim and In re Woodruff. The MPEP further states: “[A] prior art reference that discloses a…
Read MoreWhat is the “obvious to try” rationale in patent law?
The “obvious to try” rationale is a valid basis for an obviousness rejection in patent law, as clarified by the Supreme Court in KSR International Co. v. Teleflex Inc. According to MPEP 2144.05: “The Supreme Court has clarified that an ‘obvious to try’ line of reasoning may properly support an obviousness rejection. … [W]hen there…
