Claim Rejections - 35 USC § 101
35 U.S.C. 101 reads as follows:
Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title.
Claim 9 is rejected under 35 U.S.C. 101 because the claimed invention is directed to a judicial exception (i.e., a law of nature, a natural phenomenon, or an abstract idea) without significantly more.
Specifically, representative Claim 9 recites:
“A method for measuring a numerical value related to vision, comprising: a step of having a subject compare how a visual target appears in a plurality of states in which the subject wearing a lens frame for eye examination looks downward, and obtaining a subjective response of the subject.”
The claim limitations in the abstract idea have been highlighted in bold above; the remaining limitations are “additional elements.”
Under the Step 1 of the eligibility analysis, we determine whether the claims are to a statutory category by considering whether the claimed subject matter falls within the four statutory categories of patentable subject matter identified by 35 U.S.C. 101: Process, machine, manufacture, or composition of matter. The above claim is considered to be in a statutory category (process).
Under the Step 2A, Prong One, we consider whether the claim recites a judicial exception (abstract idea). In the above claim, the highlighted portion constitutes an abstract idea because, under a broadest reasonable interpretation, it recites limitations that fall into/recite an abstract idea exceptions. Specifically, under the 2019 Revised Patent Subject matter Eligibility Guidance, it falls into the groupings of subject matter that covers certain methods of organizing human activity, specifically managing personal behavior or relationships or interactions between people – including social activities, teaching, and following rules or instructions.
For example, the step of “having a subject compare how a visual target appears… and obtaining a subjective response of the subject” is treated as belonging to managing personal behavior or relationships or interactions between people grouping. These managing personal behavior or relationships or interactions between people steps represent a process that, under its broadest reasonable interpretation, covers following rules or instructions. In the context of this claim, this step encompasses a doctor or examiner having the subject look down at visual targets during an eye examination in order to compare the visual targets and then obtain a response from the subject.
The above claim 9 does not include additional elements that are sufficient to amount to significantly more than the judicial exception (Step 2B analysis) because these additional elements/steps are well-understood and conventional in the relevant art based on the prior art of record that includes prior art Tran and Lin used in the rejections below.
Hence, the claim is not patent eligible.
Claim Rejections - 35 USC § 102
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:

Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 6-7 and 10-17 are rejected under 35 U.S.C. 103 as being unpatentable over Tran et al., US 2021/0290053 A1 (hereinafter referred to as Tran), and further in view of Lin, CN 112754424 A (hereinafter referred to as Lin of record).

Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the configuration of the lens frame of Tran with the configuration of the line of sight coinciding with optical axis of the lens when the subject looks downward of Lin, for the purposes of using a common technique for providing more accurate parameters for the subsequent configuration of glasses (para 53).
