Office Action

§103 §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 . Continued Examination Under 37 CFR 1.114 In view of the Pre-Appeal Brief filed on 06/29/2026, PROSECUTION IS HEREBY REOPENED. New grounds of rejections are set forth below. To avoid abandonment of the application, appellant must exercise one of the following two options: (1) file a reply under 37 CFR 1.111 (if this Office action is non-final) or a reply under 37 CFR 1.113 (if this Office action is final); or, (2) initiate a new appeal by filing a notice of appeal under 37 CFR 41.31 followed by an appeal brief under 37 CFR 41.37. The previously paid notice of appeal fee and appeal brief fee can be applied to the new appeal. If, however, the appeal fees set forth in 37 CFR 41.20 have been increased since they were previously paid, then appellant must pay the difference between the increased fees and the amount previously paid. A Supervisory Patent Examiner (SPE) has approved of reopening prosecution by signing below: /MARIS R KESSEL/ Supervisory Patent Examiner, Art Unit 1758 Claims Status Claims 1-8, 10-12, 14-19, and 21-23 remain pending in the application. Claims 10-12, 14-19, and 21-23 are withdrawn. Claim Interpretation The following is a quotation of 35 U.S.C. 112(f): (f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The following is a quotation of pre-AIA 35 U.S.C. 112, sixth paragraph: An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The claims in this application are given their broadest reasonable interpretation using the plain meaning of the claim language in light of the specification as it would be understood by one of ordinary skill in the art. The broadest reasonable interpretation of a claim element (also commonly referred to as a claim limitation) is limited by the description in the specification when 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is invoked. As explained in MPEP § 2181, subsection I, claim limitations that meet the following three-prong test will be interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph: (A) the claim limitation uses the term “means” or “step” or a term used as a substitute for “means” that is a generic placeholder (also called a nonce term or a non-structural term having no specific structural meaning) for performing the claimed function; (B) the term “means” or “step” or the generic placeholder is modified by functional language, typically, but not always linked by the transition word “for” (e.g., “means for”) or another linking word or phrase, such as “configured to” or “so that”; and (C) the term “means” or “step” or the generic placeholder is not modified by sufficient structure, material, or acts for performing the claimed function. Use of the word “means” (or “step”) in a claim with functional language creates a rebuttable presumption that the claim limitation is to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites sufficient structure, material, or acts to entirely perform the recited function. Absence of the word “means” (or “step”) in a claim creates a rebuttable presumption that the claim limitation is not to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is not interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites function without reciting sufficient structure, material or acts to entirely perform the recited function. Claim limitations in this application that use the word “means” (or “step”) are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. Conversely, claim limitations in this application that do not use the word “means” (or “step”) are not being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. This application includes one or more claim limitations that do not use the word “means,” but are nonetheless being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because the claim limitation(s) uses a generic placeholder that is coupled with functional language without reciting sufficient structure to perform the recited function and the generic placeholder is not preceded by a structural modifier. Such claim limitation(s) is/are: “immuno-chromatographic diagnosis system being configured to: …” in claim 1. Because this/these claim limitation(s) is/are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, it/they is/are being interpreted to cover the corresponding structure described in the specification as performing the claimed function, and equivalents thereof. If applicant does not intend to have this/these limitation(s) interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, applicant may: (1) amend the claim limitation(s) to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph (e.g., by reciting sufficient structure to perform the claimed function); or (2) present a sufficient showing that the claim limitation(s) recite(s) sufficient structure to perform the claimed function so as to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 1-8 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Regarding claim 1, claim 1 recites “the immuno-chromatographic diagnosis system being configured to: select…process…provide…calculate…determine…and transmit…”. The specification, pages 20-21, merely recites a device comprising a selection means, imaging processing means, determination means, and transmission means to perform the claimed functions. However, the disclosure are devoid of any structures or algorithm of the selection means, imaging processing means, determination means, and transmission means, that performs the functions of the immuno-chromatographic diagnosis system in the claim. Thus, the disclosure does not provide adequate structure to perform the claimed function of “select…process…provide…calculate…determine…and transmit…”. The specification does not demonstrate that applicant has made an invention that achieves the claimed function because the invention is not described with sufficient detail that one of ordinary skill in the art can reasonably conclude that the inventor had possession of the claimed invention. Claims 2-8 are rejected by virtue of their dependency on all of the limitations and the written description issues of claim 1. 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 1-8 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 applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Regarding claim 1, claim limitation “immuno-chromatographic diagnosis system” invokes 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. However, the written description fails to disclose the corresponding structure, material, or acts for performing the entire claimed function and to clearly link the structure, material, or acts to the function. The specification, pages 20-21, merely recites a device comprising a selection means, imaging processing means, determination means, and transmission means to perform the claimed functions. However, the disclosure are devoid of any structures or algorithm of the selection means, imaging processing means, determination means, and transmission means, that performs the functions of the immuno-chromatographic diagnosis system in the claim. Thus, the disclosure does not provide adequate structures or algorithms to perform the claimed function of “select…process…provide…calculate…determine…and transmit…” and fails to clearly link structures, materials, or acts to the function. Note that MPEP 2181(II)(B) states that for a computer-implemented 35 U.S.C. 112(f) claim limitation, the specification must disclose an algorithm for performing the claimed specific computer function, or else the claim is indefinite under 35 U.S.C. 112(b). As discussed above, the specification fails to disclose an algorithm for performing the claimed specific computer function of “select…process…provide…calculate…determine…and transmit…”. Therefore, the claim is indefinite and is rejected under 35 U.S.C. 112(b) or pre-AIA 35 U.S.C. 112, second paragraph. Applicant may: (a) Amend the claim so that the claim limitation will no longer be interpreted as a limitation under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph; (b) Amend the written description of the specification such that it expressly recites what structure, material, or acts perform the entire claimed function, without introducing any new matter (35 U.S.C. 132(a)); or (c) Amend the written description of the specification such that it clearly links the structure, material, or acts disclosed therein to the function recited in the claim, without introducing any new matter (35 U.S.C. 132(a)). If applicant is of the opinion that the written description of the specification already implicitly or inherently discloses the corresponding structure, material, or acts and clearly links them to the function so that one of ordinary skill in the art would recognize what structure, material, or acts perform the claimed function, applicant should clarify the record by either: (a) Amending the written description of the specification such that it expressly recites the corresponding structure, material, or acts for performing the claimed function and clearly links or associates the structure, material, or acts to the claimed function, without introducing any new matter (35 U.S.C. 132(a)); or (b) Stating on the record what the corresponding structure, material, or acts, which are implicitly or inherently set forth in the written description of the specification, perform the claimed function. For more information, see 37 CFR 1.75(d) and MPEP §§ 608.01(o) and 2181. Prior Art Regarding claim 1, the closest prior art of Rao et al. (US 20150087543 A1, cited in the IDS filed 02/27/2024) fails to teach: wherein each of the plurality of diagnosis couples consists of (b) a competitive ligand, labeled with at least one visualization molecule detectable with fluorescence, and wherein the recognition biological molecule is disposed in a reaction mixture and the competitive ligand is bonded to a distinct and known recovery location on a solid support, or vice versa; and for a given coordinate Y, the plurality of recovery locations along X corresponds to a second plurality of the diagnosis couples; (iii) at least one container comprising the reaction mixture, wherein the at least one container comprising the reaction mixture is separated from the solid support; the immuno-chromatographic diagnosis system being configured to: select, from the plurality of distinct and known recovery locations of the solid support, a subset of the plurality of the distinct and known recovery locations to be detected and/or quantified; process an image of the visualization zone to determine a finite number of subassemblies of the image, wherein each subassembly corresponds to one of the subset of the plurality of the distinct and known recovery locations on the porous membrane and identifies a distinct one of the analytes in the migration direction; provide data related to light intensities coming from the subassemblies; calculate from the data related to light intensities coming from the subassemblies, for each subassembly that corresponds to at least one of the subset of the plurality of the distinct and known recovery locations on the solid support, a subassembly intensity; determine, based on the subassembly intensity, information for the at least one of the subset of the plurality of different analytes in the liquid sample; and transmit information for each subassembly corresponding to at least one of the plurality of different analytes of the liquid sample. A reference Cekli et al. (US 20190137892 A1; effectively filed 05/12/2016) teaches measurements form locations across a substrate (abstract). Cekli teaches in the case where the type of measurement made at the preliminary subset of locations is different than the type of measurement made at the selected set of locations, it will be understood that different types of target structure may be involved in the different types of measurement (paragraph [0131]). However, Cekli fails to teach or suggest all of the limitations of claim 1. None of the prior art teaches or fairly suggests, alone or in combination, all of the limitations of claim 1, specifically “the immuno-chromatographic diagnosis system being configured to: select, from the plurality of distinct and known recovery locations of the solid support, a subset of the plurality of the distinct and known recovery locations to be detected and/or quantified.” Additionally, the prior art fails to teach or fairly suggests claims 2-8 based on their dependency on all of the limitations of claim 1. Response to Arguments Applicant’s arguments, see pages 1-2, filed 06/29/2026, with respect to rejections under 35 U.S.C. 103, have been fully considered and are persuasive. The rejections under 35 U.S.C. 103 of 01/28/2026 have been withdrawn.
