Office Action

§112
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 . DETAILED ACTION Currently, claims 1-4 are pending and examined below. Priority Acknowledgment is made of applicant’s claim for foreign priority under 35 U.S.C. 119 (a)-(d). Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1-4 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor, or for pre-AIA the applicant regards as the invention. Section 2173.02.I. of the MPEP provides the following guidance on how pre-issuance claims under examination are construed differently than patented claims: Patented claims are not given the broadest reasonable interpretation during court proceedings involving infringement and validity, and can be interpreted based on a fully developed prosecution record. While "absolute precision is unattainable" in patented claims, the definiteness requirement "mandates clarity." Nautilus, Inc. v. Biosig Instruments, Inc., 527 U.S. __, 134 S. Ct. 2120, 2129, 110 USPQ2d 1688, 1693 (2014). A court will not find a patented claim indefinite unless the claim interpreted in light of the specification and the prosecution history fails to "inform those skilled in the art about the scope of the invention with reasonable certainty." Id. at 1689. PNG media_image1.png 18 19 media_image1.png Greyscale The Office does not interpret claims when examining patent applications in the same manner as the courts. In re Packard, 751 F.3d 1307, 1312, 110 USPQ2d 1785, 1788 (Fed. Cir. 2014); In re Morris, 127 F.3d 1048, 1054, 44 USPQ2d 1023, 1028 (Fed. Cir. 1997); In re Zletz, 893 F.2d 319, 321-22 (Fed. Cir. 1989). The Office construes claims by giving them their broadest reasonable interpretation during prosecution in an effort to establish a clear record of what the applicant intends to claim. Such claim construction during prosecution may effectively result in a lower threshold for ambiguity than a court's determination. Packard, 751 F.3d at 1323-24, 110 USPQ2d at 1796-97 (Plager, J., concurring). However, applicant has the ability to amend the claims during prosecution to ensure that the meaning of the language is clear and definite prior to issuance or provide a persuasive explanation (with evidence as necessary) that a person of ordinary skill in the art would not consider the claim language unclear. In re Buszard, 504 F.3d 1364, 1366 (Fed. Cir. 2007)( claims are given their broadest reasonable interpretation during prosecution "to facilitate sharpening and clarifying the claims at the application stage"); see also In re Yamamoto, 740 F.2d 1569, 1571 (Fed. Cir. 1984); In re Zletz, 893 F.2d 319, 322, 13 USPQ2d 1320, 1322 (Fed. Cir. 1989). Here, the independent claim 1 is indefinite for two reasons: First, it is unclear whether “the first conductive line” refers to all of “a plurality of first conductive lines” or just one of the “plurality of first conductive lines.” Second, “the single first conductive line” lacks antecedent basis. For the purpose of advancing the examination of the instant application, “the first conductive line” and “the single first conductive line” have been interpreted as referring to just one of the “plurality of first conductive lines.” Claim 2 is indefinite, because it depends from the indefinite independent claim 1. Independent claim 3 is indefinite for the same two reasons that the independent claim 1 is indefinite. In addition, the independent claim 3 if further indefinite, because “the third conductive line” lacks antecedent basis. Claim 4 is indefinite, because it depends from the indefinite independent claim 3. Allowable Subject Matter The following is a statement of reasons for the indication of allowable subject matter: But for its pending 35 U.S.C. 112(b) rejection, the independent claim 1 would be allowable. PNG media_image2.png 504 753 media_image2.png Greyscale Regarding independent claim 1, Chen (Pub. No. US 2024/0407151 A1 to Chen et al.) teaches a DRAM device (see Fig. 8A for example), comprising: a substrate SiSub (para [0109] - “a silicon substrate SiSub.”); a plurality of first conductive lines 841 (para [0102] - “multiple conductive plugs 841”) oriented in a first direction perpendicular Z to an upper surface of the substrate SiSub, and disposed parallel to each other at predetermined intervals, a plurality of second conductive lines 820, 830 (para [0103] - “…the disposed positions of two adjacent first conductive structures 820 are staggered from each other, and the disposed positions of two adjacent second conductive structures 830 are also staggered from each other, as shown in FIG. 8B.”) located (indirectly) on the first conductive lines 841, and disposed parallel to each other in a second direction perpendicular X to the first conductive line 841 at predetermined intervals, a plurality of channel patterns 810 each extending in a third direction Y perpendicular to both the first direction Z and the second direction X, and a gate insulating pattern CI1-Cl4 (para [0072] - “multiple dielectric layers CI1 to CI4”) located on the plurality of channel patterns 810; wherein the plurality of second conductive lines 820, 830 comprises a first subline 820 and a second subline 830 which are at different distances from the first conductive line 841, and the first subline 820 and the second subline 830 are provided alternating with each other in the first direction Z. Nevertheless, the independent claim 1 is allowable, because the prior art of record, singularly or in combination, fails to disclose or suggest, in combination with the other claimed elements in claim 1, a plurality of channel patterns arranged in a honeycomb structure on the first conductive line; a gate insulating pattern located between the plurality of channel patterns and the plurality of second conductive lines; and the plurality of channel patterns located on the single first conductive line are arranged in zigzag along both edges of the single first conductive line, and the plurality of channel patterns contacting the single second conductive line are arranged in a straight line. Claim 2 is allowable, because it depends from the allowable independent claim 1. Independent claim 3 is allowable, because the prior art of record, singularly or in combination, fails to disclose or suggest, in combination with the other claimed elements in claim 3, a plurality of channel patterns arranged in a honeycomb structure on the first conductive line; a gate insulating pattern located between the plurality of channel patterns and the plurality of second conductive lines or the plurality of third conductive lines; and the plurality of channel patterns located on the single first conductive line are arranged in zigzag along both edges of the single first conductive line, and the plurality of channel patterns contacting the single second conductive line or the third conductive line are are arranged in a straight line. Claim 4 is allowable, because it depends from the allowable independent claim 3. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure: Pub. No. US 2024/0098969 A1 to Hwang et al. Pub. No. US 2023/0413517 A1 to Kim et al. Pub. No. US 2023/0180455 A1 to Choi et al. Pub.
