What is the significance of reciting only a field of use in patent claims?
Reciting only a field of use in patent claims is generally insufficient to make an abstract idea patent-eligible. According to MPEP 2106.05(f): “A claim directed to an abstract idea cannot be made eligible ‘simply by having the applicant acquiesce to limiting the reach of the patent for the formula to a particular technological use.’ Thus,…

The “mere drafting effort” exception in Step 2B of the patent eligibility analysis refers to cases where the additional elements in a claim are simply an attempt to limit the use of an abstract idea to a particular technological environment or field of use. This exception is explained in MPEP 2106.05(h): “[S]imply limiting the use…
Read MoreHow can examiners determine if a limitation is merely a field of use or technological environment?
Patent examiners need to carefully evaluate claim limitations to determine if they merely indicate a field of use or technological environment. The MPEP 2106.05(h) provides guidance on this process: “For claim limitations that generally link the use of the judicial exception to a particular technological environment or field of use, examiners should explain in an…
Read MoreHow does the field of use consideration differ from insignificant extra-solution activity?
The field of use consideration and insignificant extra-solution activity are both important aspects of patent eligibility analysis, but they can sometimes overlap. According to MPEP 2106.05(h): “Examiners should keep in mind that this consideration overlaps with other considerations, particularly insignificant extra-solution activity (see MPEP § 2106.05(g)). For instance, a data gathering step that is limited…
Read MoreWhat is the “field of use and technological environment” consideration in patent eligibility?
The “field of use and technological environment” consideration is part of the patent eligibility analysis under 35 U.S.C. § 101. It examines whether the additional elements in a claim amount to more than generally linking the use of a judicial exception (such as an abstract idea) to a particular technological environment or field of use.…

The concept of field of use is particularly relevant to the Step 2B analysis in the Alice/Mayo test for patent eligibility. According to MPEP 2106.05(h): “Another consideration when determining whether a claim integrates the judicial exception into a practical application in Step 2A Prong Two or recites significantly more than a judicial exception in Step…
Read MoreHow does “field of use” affect patent eligibility?
The concept of “field of use” is important in patent eligibility analysis. According to MPEP 2106.05(h): “Another consideration when determining whether a claim integrates the judicial exception into a practical application in Step 2A Prong Two or recites significantly more than a judicial exception in Step 2B is whether the additional elements amount to more…
Read MoreWhat are some examples of limitations that courts have described as merely indicating a field of use?
The MPEP 2106.05(h) provides several examples of limitations that courts have described as merely indicating a field of use or technological environment. Here are some key examples: Limiting drug administration to patients with a specific disorder (Mayo Collaborative Servs. v. Prometheus Labs. Inc.) Identifying participants in a hedging process as commodity providers and consumers (Bilski…
Read MoreWhat is a classic example of a field of use limitation?
A classic example of a field of use limitation comes from the case Parker v. Flook, as cited in MPEP 2106.05(h). In this case, the claim recited steps for calculating an updated alarm limit value using a mathematical formula in the context of “a process comprising the catalytic chemical conversion of hydrocarbons.” The Supreme Court…
