What is the requirement for substituting equivalents in patent obviousness?
When considering the substitution of equivalents in patent obviousness determinations, there are specific requirements outlined in MPEP 2144.06. The key requirement is that the equivalency must be recognized in the prior art. As stated in the MPEP: “In order to rely on equivalence as a rationale supporting an obviousness rejection, the equivalency must be recognized…
Read MoreHow can an inventor overcome an obviousness rejection based on art recognized equivalence?
An inventor facing an obviousness rejection based on art recognized equivalence can employ several strategies to overcome the rejection. Here are some approaches based on the principles outlined in MPEP 2144.06: Challenge the Equivalency: Argue that the prior art does not actually recognize the equivalency between the components. Remember, the MPEP states: “In order to…

The In re Kerkhoven case is significant in patent law as it established a key principle regarding the combination of known elements. As cited in MPEP 2144.06, the case states: “It is prima facie obvious to combine two compositions each of which is taught by the prior art to be useful for the same purpose,…
Read MoreWhat is the difference between combining and substituting equivalents in patent law?
In patent law, there is a distinction between combining equivalents and substituting equivalents, as outlined in MPEP 2144.06. The key differences are: Combining Equivalents: This involves using two or more components together, each known for the same purpose, to create a new composition or method for that same purpose. The In re Kerkhoven case exemplifies…
Read MoreHow does combining equivalents affect patent obviousness?
Combining equivalents can affect patent obviousness by making a new composition or method prima facie obvious. According to MPEP 2144.06: “It is prima facie obvious to combine two compositions each of which is taught by the prior art to be useful for the same purpose, in order to form a third composition to be used…
Read MoreWhat is the principle of “Art Recognized Equivalence for the Same Purpose” in patent law?
The principle of “Art Recognized Equivalence for the Same Purpose” is a legal concept in patent law that allows patent examiners to combine or substitute known equivalents in determining obviousness. This principle is outlined in MPEP 2144.06 and is based on two main ideas: Combining equivalents known for the same purpose Substituting equivalents known for…
Read MoreHow does the concept of “Art Recognized Equivalence” apply to mechanical inventions?
The concept of “Art Recognized Equivalence” applies to mechanical inventions in much the same way as it does to chemical compositions. According to MPEP 2144.06, the principle can be applied to functional or mechanical equivalents. However, it’s important to note: “The mere fact that components are claimed as members of a Markush group cannot be…
Read MoreCan an applicant’s recognition of equivalents be used in patent examination?
Yes, an applicant’s recognition of equivalents can be used in patent examination, but with specific limitations. According to MPEP 2144.06: “However, an applicant’s expressed recognition of an art-recognized or obvious equivalent may be used to refute an argument that such equivalency does not exist.” This means that while an examiner cannot rely solely on an…
