DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . 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 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. Response to Arguments I. Election/Restrictions 1. Applicant’s election without traverse of Species 1A including claims 1-12 and 18-20 in the reply filed on 06/16/2026 is acknowledged. Claims 13-17 were not elected. 2. There was no new set of claims filed with said reply with the proper status identifier such as Original, Withdrawn, Canceled, etc. Therefore, the status of claims is improper. Consequently, appropriate correction is required. Title Objection 3. The title of the invention is not descriptive. A new title is required that is clearly indicative of the invention to which the claims are directed. Examiner’s Note 4. All the words in the language of the claims of which the specifications do not provide a definition in the form stated in the MPEP, the examiner has interpreted them by their plain meanings, pursuant to the MPEP 2111.01 “Plain Meaning” and MPEP 2173.01. 27. The rejection was issued under 103 because it is uncertain whether each figure of the prior art is an embodiment or several figures could constitute a single embodiment. 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 of this title, 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.

REVERSAL, DUPLICATION, OR REARRANGEMENT OF PARTS, the Rearranging/shifting the position of the lines with respect to each other and/or other components does not modify the operation of the sensor in a novel manner, therefore, components’ positions and/or rearrangement has no patentable weight (see “In re Japikse, 181 F.2d 1019, 86 USPQ 70 (CCPA 1950)). Additionally, rearranging the component positions is an obvious design choice (see “In re Kuhle, 526 F.2d 553, 188 USPQ 7 (CCPA 1975)). Furthermore, if the aforesaid arrangements modify the apparatus in an unpredictable manner, it should be added language claiming the aforesaid unpredictable manner in order to add patentability weight to the claim. As per claim 18, Shao discloses: A test method (See MPEP 2111.02, Effect of Preamble, and II. Preamble Statements Reciting Purpose or Intended Use), comprising: receiving a test signal (see [0021]); and selecting one of N groups of test units (Figs. 2 and 7, see the switching circuit 130 and the control circuit 140. Also see claim-1 and/or [0019]-[0020]) based on the test signal (see [0021]); and connecting at least some of M groups of pads to the test units in the selected group of test units in one-to-one correspondence (see claim-1 and/or [0020]), wherein M and N are both integers greater than 1 (Fig. 8, see the testing-pads 110 and testing-units 120 being greater than 1.

Also see [0039] and [0019]), and a total number of the test units among the N groups of test units is greater than M (Fig. 8, see the total number of testing-units 120 being greater than testing-pads 110. Also see [0039] and [0018]). As per claim 20, Shao discloses the test method of claim 18 as described above. Shao further discloses: generating a selection signal (see [0035], [0019] and [0021]. The logical high-control-signal based on the test-signal) based on the test signal (see [0021]), wherein the selection signal is configured to indicate to select one of the N groups of test units (see [0035] and [0019]. The high-control-signal that activates and indicates the activation of testing-unit 120A from the plurality of testing units 120); and receiving the selection signal, and enabling a connection between the test units in the selected group of test units and at least some of the groups of pads among the M groups of pads according to the selection signal (see [0035] and [0019].

Claim(s) 19 are/is rejected under 35 U.S.C. 103 as being unpatentable over Shao in view of Chang et al. (Pub. No.: US 2022/0367299 hereinafter mentioned as “Chang”). As per claim 19, Shao discloses the test method of claim 18 as described above. Shao discloses testing the test units in the selected group of test units via at least some of the groups of test pads among the M groups of pads as described above but does not explicitly disclose that it is done by using a test probe. However, Chang further discloses: testing the test units in the selected group of test units via at least some of the groups of test pads among the M groups of pads by using a test probe (see [0056] and [0017]). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to implement the feature relative to testing the test units in the selected group of test units via at least some of the groups of test pads among the M groups of pads of Shao by using a “test probe”, as disclosed by Chang, with the motivation and expected benefit related to improving the system, methods and measurements by simultaneously testing two testing units (Chang, Paragraph [0056]), thus, testing a desirable sufficient number of test units to effectively and efficiently monitor degradations (Chang, Paragraph [0017]). Furthermore, Shao states that “Those skilled in the art should appreciate that they may readily use the present disclosure as a basis for designing or modifying other processes and structures for carrying out the same purposes ...” (Shao, Paragraph [0052]). Furthermore, Chang states that “Those skilled in the art should appreciate that they may readily use the present disclosure as a basis for designing or modifying other processes and structures for carrying out the same purposes ...” (Chang, Paragraph [0105]). Allowable Subject Matter 7. Claim(s) 6 and 10 are/is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. 8. The following is an examiner's statement of reasons for the objection: 9. Regarding claim 6, the prior art of record, alone or in combination, does not disclose or suggest the below underlined limitations incorporated together with the other claimed limitations not mentioned herein: wherein the first control sub-circuit comprises one decoder and N comparators; and an output terminal of the decoder is connected with input terminals of the N comparators, and output terminals of the N comparators are in one-to-one correspondence with the N groups of test units; the decoder is configured to receive the test signal and output a decoded signal to the input terminals of the N comparators; each of the N comparators is configured to receive a reference signal and the decoded signal and output a 1-bit selection sub-signal, and N 1-bit selection sub-signals output by the N comparators constitute an N-bit selection signal; and each group of test units among the N groups of test units corresponds to a unique reference signal. 10. Regarding claim 10, the prior art of record, alone or in combination, does not disclose or suggest the below underlined limitations incorporated together with the other claimed limitations not mentioned herein: wherein the N is equal to 2, the M is equal to 4, and a number of the word lines in each group of test units among the N groups of test units is equal to 4; and a second control sub-circuit of the control circuit comprises 2 groups of transistors that are in one-to-one correspondence with 2 groups of test units among the N groups of test units, and a number of transistors in each of the groups of transistors is equal to 4; and each group of pads among the M groups of pads is connected with 2 test units in different groups of test units among the N groups of test units. 11. The prior art of record does not anticipate the limitations of the independent claims. Furthermore, there is not any obvious motivation for an ordinary skilled in the art to combine some and/or all of the features of the prior art of record to achieve the features of the allowable subject matter. In addition, it will further require substantial structural modification of the components that will also require substantial modification of the measurements, signal processing and configurations to achieve the features of the allowable subject matter.
