Office Action

§112
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 . Specification The disclosure is objected to because of the following informalities: Table 3 appears to have a mislabeled column “NTU difference estimate,” which should be “Temperature-specific NTU Measurement Value” or “NTU Measurement Value.” Appropriate correction is required. 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: “a control part” in claims 1 and 7. 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. Claims 1, 7, and 10 perform calculation of temperature-specific turbidity correction values by reflecting the temperature-specific turbidity value difference estimates which is nonstandard language for a calculation. Applicant may be their own lexicographer, and so this limitation has been interpreted to be the calculation of reflecting defined by the specification at paragraph 85. 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 5, 11, and 12 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. Claim 5 recites the limitation "the test solution having different turbidities at the same temperature." There is insufficient antecedent basis for this limitation in the claim. Claim 5 recites the limitation "the test solution.” There is insufficient antecedent basis for this limitation in the claim because there are plural different test solutions. Claim 5 recites the limitation "the photosensor." There is insufficient antecedent basis for this limitation in the claim because there are plural photosensors. Claim 5 recites “a same turbidity” and “the same turbidity” of the test solution which is not understood because claim 1 requires a test solution with a same turbidity and claim 5 requires a test solution with different turbidities. It is unclear what the same turbidity refers to. Claim 11 recites the limitations "the test solutions having different turbidities at a same temperature" and “the test solutions having different turbidities.” There is insufficient antecedent basis for this limitation in the claim. Claim 11 recites the limitation "the test solution.” There is insufficient antecedent basis for this limitation in the claim because there are plural different test solutions. Claim 11 recites “a same turbidity” and “the same turbidity” of the test solution which is not understood because claim 10 requires a test solution with a same turbidity and claim 11 requires a test solution with different turbidities. It is unclear what the same turbidity refers to. Claim 12 recites a step to conditionally exclude the detected photosensors from those for temperature-specific turbidity value correction, presumably omitting certain steps from claims 1, and 11. It is unclear which specific steps from claims 1 and 11 are not being performed when a photosensor is excluded from temperature-specific turbidity value correction. The following is a quotation of 35 U.S.C. 112(d): (d) REFERENCE IN DEPENDENT FORMS.—Subject to subsection (e), a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. The following is a quotation of pre-AIA 35 U.S.C. 112, fourth paragraph: Subject to the following paragraph [i.e., the fifth paragraph of pre-AIA 35 U.S.C. 112], a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. Claim 12 is rejected under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends. Claim 12 conditionally excludes photosensors from temperature-specific turbidity value correction, presumably excluding at least some of the steps for the method for temperature-specific turbidity value correction in claim 1. In the case of the difference between the first conversion value and the second conversion value being within a preset range for all photosensors, these limitations effectively omit portions of the claims performing temperature-specific turbidity value correction. Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements. Allowable Subject Matter Claims 1-4, 6-10, and 13-15 are allowed. The following is a statement of reasons for the indication of allowable subject matter: the prior art does not disclose, or render obvious, the temperature-specific performance deviation correction apparatus as defined by claim 1; the washing machine as defined by claim 7; or the correction method of correcting temperature-specific performance deviations of a plurality of photosensors as defined by claim 10. There is no apparent teaching, suggestion, or motivation to modify the closest prior art, Engel (US 5,889,192), to further include the steps for correcting the turbidity values as claimed. In contrast to the claimed invention, Engel discloses a method for temperature compensation of measured values of the turbidity sensor includes calculating a temperature coefficient of the turbidity sensor for each operating point and storing the temperature coefficient in memory as a correction value in software for evaluating measurement results of the turbidity sensor, wherein a respective measurement result is corrected by using the temperature coefficient as a function of a temperature being present and measured at the turbidity sensor (abstract).
