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 . Claim Rejections - 35 USC § 112 Note that dependent claims will have the deficiencies of base and intervening claims. 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 5-14 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: a) claim 5 requires PNG media_image1.png 80 640 media_image1.png Greyscale The phrase “a target land” appears to be unique to Applicant in the corrosion measurement arts. Applicant is requested to clarify the scope of this phrase. If Applicant is being his own lexicographer, please heed MPEP 2173.05(a). b) claim 5 requires PNG media_image2.png 170 730 media_image2.png Greyscale The term “damping function” appears to be unique to Applicant in the corrosion measurement arts. Applicant’s only example of a damping function is as set forth in claim 7, which is also in Applicant’s originally filed specification paragraph [0044], PNG media_image3.png 236 722 media_image3.png Greyscale It is not clear how this example damping function is “representing” any sort of ratio. Applicant is requested to clarify the scope of the term “damping function” and how he is using the word “representing”. If Applicant is being his own lexicographer, please heed MPEP 2173.05(a). c) claim 5 requires PNG media_image4.png 102 708 media_image4.png Greyscale The word ratio, as a noun, is conventionally understood as follows PNG media_image5.png 442 812 media_image5.png Greyscale Excerpted from the Merriam-Webster’s online dictionary, underlining added. So, the ratio in claim 5 is incomplete as there is no indication as to what mathematical expression or quantity “an area wetted with water on a surface of a metal structure buried in the target land based the water content measured in the measurement step” is in mathematical relationship (ratio) to or what the other expression of the (ratio) quotient is. If Applicant is being his own lexicographer, please heed MPEP 2173.05(a). d) claim 5 requires PNG media_image6.png 134 686 media_image6.png Greyscale The limitation “a second processing step of estimating a rate increase function that increases an estimated corrosion rate of the metal structure, . . . .” is very vague. Does this processing step encompass increasing any estimated corrosion rate of the metal structure by any amount. e) claim 5 requires PNG media_image7.png 140 670 media_image7.png Greyscale Claim 8 recites PNG media_image8.png 244 702 media_image8.png Greyscale It is not possible for the rate increase function of claim 8 to increase an estimated corrosion rate of the metal structure as there is no term representing an estimated corrosion rate of the metal structure in this function (“t” represents time, see claim 7). Applicant is requested to clarify how the second processing step of claim 5 is to be understood in light of claim 8. f) claim 5 recites PNG media_image9.png 380 748 media_image9.png Greyscale It is not clear how Applicant is using the word “estimating” in regard to estimating the highlighted functions above. For example, what makes the damping function presented in claim 7 an estimated damping function? g) claim 6 requires PNG media_image10.png 144 730 media_image10.png Greyscale This fourth processing step is inconsistent with underlying claim 5 as the second and third processing step require PNG media_image11.png 202 696 media_image11.png Greyscale That is, as best understood by the Examiner, while the fourth processing step obtains the estimated corrosion rate of the metal structure based on the temporal change function, the proceeding steps obtains the temporal change function based on the estimated corrosion rate. Put another way, how can the corrosion rate of the metal structure be estimated based on the temporal change function when the temporal change function is itself based on the estimated corrosion rate? h) claim 7 requires PNG media_image12.png 242 726 media_image12.png Greyscale It is not clear how the word “presented” is being used in this claim, particularly in contrast to “is”. i) claim 8 requires PNG media_image13.png 240 740 media_image13.png Greyscale It is not clear how the word “represented” is being used in this claim, particularly in contrast to “is”. j) claim 9 requires PNG media_image14.png 234 730 media_image14.png Greyscale It is not clear how the word “represented” is being used in this claim, particularly in contrast to “is”. k) claim 10 requires PNG media_image15.png 80 612 media_image15.png Greyscale The phrase “a target land” appears to be unique to Applicant in the corrosion measurement arts. Applicant is requested to clarify the scope of this phrase. If Applicant is being his own lexicographer, please heed MPEP 2173.05(a). l) claim 10 requires PNG media_image16.png 104 694 media_image16.png Greyscale The term “damping function” appears to be unique to Applicant in the corrosion measurement arts. Applicant’s only example of a damping function is as set forth in claim 12, which is also in Applicant’s originally filed specification paragraph [0044], PNG media_image17.png 218 730 media_image17.png Greyscale It is not clear how this example damping function is “representing” any sort of ratio. Applicant is requested to clarify the scope of the term “damping function” and how he is using the word “representing”. If Applicant is being his own lexicographer, please heed MPEP 2173.05(a). m) claim 10 requires PNG media_image18.png 104 694 media_image18.png Greyscale The word ratio, as a noun, is conventionally understood as follows PNG media_image5.png 442 812 media_image5.png Greyscale Excerpted from the Merriam-Webster’s online dictionary, underlining added. So, the ratio in claim 10 is incomplete as there is no indication as to what mathematical expression or quantity “an area wetted with water on a surface of a metal structure buried in the target land based the water content measured in the measurement step” is in mathematical relationship to. If Applicant is being his own lexicographer, please heed MPEP 2173.05(a). n) claim 10 requires PNG media_image19.png 110 700 media_image19.png Greyscale The limitation “estimate a rate increase function that increases an estimated corrosion rate of the metal structure, . . . .” is very vague. Does this processing step encompass increasing any estimated corrosion rate of the metal structure by any amount. o) claim 10 requires PNG media_image20.png 110 700 media_image20.png Greyscale Claim 13 recites PNG media_image21.png 230 724 media_image21.png Greyscale It is not possible for the rate increase function of claim 13 to increase an estimated corrosion rate of the metal structure as there is no term representing an estimated corrosion rate of the metal structure in this function (“t” represents time, see claim 12). Applicant is requested to clarify how the second instruction of claim 10 (”estimate a rate increase function”) is to be understood in light of claim 13. p) claim 10 recites PNG media_image22.png 448 740 media_image22.png Greyscale It is not clear how Applicant is using the word “estimate” in regard to estimating the highlighted functions above. For example, what makes the damping function presented in claim 12 an estimated damping function? q) claim 11 requires PNG media_image23.png 154 714 media_image23.png Greyscale This instruction is inconsistent with underlying claim 10 as the previous instructions require PNG media_image24.png 174 742 media_image24.png Greyscale That is, as best understood by the Examiner, while the additional instruction of claim 11 obtains the estimated corrosion rate of the metal structure based on the temporal change function, the proceeding instructions in claim 10 obtain the temporal change function based on the estimated corrosion rate. Put another way, how can the corrosion rate of the metal structure be estimated based on the temporal change function when the temporal change function is itself based on the estimated corrosion rate? r) claim 12 requires PNG media_image25.png 220 676 media_image25.png Greyscale It is not clear how the word “presented” is being used in this claim, particularly in contrast to “is”. s) claim 13 requires PNG media_image26.png 232 704 media_image26.png Greyscale It is not clear how the word “represented” is being used in this claim, particularly in contrast to “is”. t) claim 14 requires PNG media_image27.png 220 650 media_image27.png Greyscale It is not clear how the word “represented” is being used in this claim, particularly in contrast to “is”. Allowable Subject Matter Claims 5 and 10 would be allowable if rewritten or amended to overcome the rejections under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action. Claims 6-9 and 11-14 would be allowable if rewritten to overcome the rejections under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action and to include all of the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: a) in claim 5 the combination of limitations requires the following underlined features PNG media_image28.png 382 694 media_image28.png Greyscale a)(i) the International Search Report for international application no. PCT/JP2021/039982 cites only “A” documents. a)(ii) the Written Opinion for international application no. PCT/JP2021/039982, based on a English language translation, deems claim s1-4 of that application to have both novelty and an inventive step. a)(iii) Dang et al., “On the Use of Voltammetry to Estimate the Effectiveness of Cathodic Protection of Buried Steel Structures,” JMEPEG (2019) 28:6042–6052 (hereafter ‘Dang”) discloses a corrosion estimation method that involves measuring a parameter (S’) linked to the wet area of buried steel structure, which is the surface of the metal in contact with the soil electrolyte, as Dang recognizes that the corrosion rate is affected by the wet area. This parameter is used in a ratio to correct a previously determined corrosion rate. See in Dang the abstract, 1. Introduction, Figure 7, and the last paragraph in the left column on page 6050, continuing into the right column on the same page. However, in contrast to the method of Applicant’s claim 5, even if would have been obvious to “estimate” a rate increase function to, perhaps, predict the remaining useful life of the buried steel structure, there is no suggestion of having this function be based in part on a thickness of a water film formed on the surface of the metal structure. b) claims 6-9 depend directly or indirectly from allowable claim 5. c) in independent claim 10 the combination of limitations requires the following underlined features PNG media_image29.png 448 710 media_image29.png Greyscale The discussion above regarding the allowability of claim 5 applies to claim 10 also. d) claims 11-14 depend directly or indirectly from allowable claim 10.
