Office Action

§101 §102
CTNF 18/405,452 CTNF 87724 DETAILED ACTION Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. Drawings 06-22 AIA The drawings are objected to because Figures 7-10, 26A-26D contains text that is partially illegible . Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Claim Rejections - 35 USC § 101 07-04-01 AIA 07-04 35 U.S.C. 101 reads as follows: Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title. Claims 1-6 are rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more. A subject matter eligibility analysis is set forth below. See MPEP 2106. Under Step 1 of the analysis, claim 1 , belongs to a statutory category namely a device. Under Step 2A, prong 1 : This part of the eligibility analysis evaluates whether the claim recites a judicial exception. As explained in MPEP 2106.04, subsection II, a claim “recites” a judicial exception when the judicial exception is “set forth” or “described” in the claim. The claim(s) 1 recite(s) concepts related to mathematical algorithms/concepts, and mental processes and concepts performed in the human mind e.g. observation, evaluation, judgment, opinion to generate at least one of: first screen display information to display performance information indicating performance of a condenser, the performance of the condenser being predicted based on measurement information that is measured or input information that is input ; and second screen display information to display residual thickness information indicating a residual ratio of thickness of a tube of the condenser, the residual ratio being predicted based on the input information.” (emphasis added) . The concepts discussed above can be considered to describe mental processes, namely concepts performed in the human mind or with pen and paper , and/or mathematical concepts, namely a series of calculations leading to one or more numerical results or answers (emphasis added). Although, the claim does not spell out any particular equation or formula being used, the lack of specific equations for individual steps merely points out that the claim would monopolize all possible calculations in performing the steps. These steps recited by the claims, therefore amount to a series of mental or mathematical steps, making these limitations amount to an abstract idea. Step 2A, prong 2 of the eligibility analysis evaluates whether the claim as a whole integrates the recited judicial exception(s) into a practical application of the exception. This evaluation is performed by (a) identifying whether there are any additional elements recited in the claim beyond the judicial exception, and (b) evaluating those additional elements individually and in combination to determine whether the claim as a whole integrates the exception into a practical application. This judicial exception is not integrated into a practical application because the abstract idea is not performed by using any particular device and because the recitation of “display information generating circuitry ” , amounts to the recitation of a general purpose computer to implement the abstract idea and the recitation of “measurement information that is measured or input information…” is mere gathering recited at high level of generality generally linking the abstract idea to ta field of use (i.e. condenser state predicting) and the results of the algorithm are merely output/stored as part of insignificant post-solution activity ( i.e. display performance information…, display residual thickness information… ), and are not used in any particular matter as to integrate the abstract idea in a practical application. Under Step 2B , the claim(s) does/do not include additional elements that are sufficient to amount to significantly more than the judicial exception because the additional elements, as described above with respect to Step 2A Prong 2, merely amount to a general purpose computer , used to apply the abstract idea and mere data gathering/output recited at a high level of generality and insignificant extra-solution activity that when further analyzed under Step 2B is found to be well-understood, routine and conventional activities as evidenced by MPEP 2106.05(d)(II); and because the data of performing the algorithm must necessarily be “obtained” and the use of a general purpose computer to implement the abstract idea for performing the algorithm does not amount to significantly more than the recitation of the abstract idea itself. Therefore, claim 1 is rejected under 35 U.S.C. 101 as directed to an abstract idea without significantly more. Dependent claims 2-6 merely expand on the abstract idea by appending additional steps to the mathematical algorithm on their respective independent claim 1. Dependent claims 2-6 merely expands on the abstract idea by reciting additional steps related to mathematical algorithms/concepts, and mental processes and concepts performed in the human mind e.g. observation, evaluation, judgment, opinion and mere characterization of the data acquired and applied for performing the abstract idea and mere data characterization. Dependent claims 2-6 , do not set forth further additional elements that integrate the rejected abstract idea into a practical application or amount to significantly more than the abstract idea itself. Therefore, these claims are found to be ineligible for the reasons described with respect to independent claim 1 from which they depend. With respect to dependent claim 6 , the claim further recites aspects of the abstract idea (i.e. “ calculation of the performance information based on the cooling water inlet temperature and the cooling water outlet temperature; and calculation of the residual thickness information based on the cumulative operating time of the condenser. ”) and introduces the additional element of “ a measurement data obtaining unit configured to obtain at least either a cooling water inlet temperature of cooling water flowing into a tube of the condenser and a cooling water outlet temperature of the cooling water discharged from the tube of the condenser or a cumulative operating time of the condenser” and “an arithmetic unit”, however this merely amounts to the recitation of a general purpose computer (i.e. an arithmetic unit) to implement the abstract idea and to mere data gathering recited at a high level of generality and generally linking the abstract idea to a field of use and to insignificant extra-solution activity. Therefore, for similar reasons as discussed above, the additional elements disclosed by dependent c laims 6 fail to integrate the recited abstract idea into a practical application or amount to significantly more than the abstract idea itself. Therefore claims 1-6 are rejected under 35 USC 101 as being directed to non-statutory subject matter. Claim Rejections - 35 USC § 102 07-06 AIA 15-10-15 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 (i.e., changing from AIA to pre-AIA) 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. 07-07-aia AIA 07-07 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – 07-08-aia AIA (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. 07-12-aia AIA (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. 07-15-aia AIA Claim(s) 1-6 is/are rejected under 35 U.S.C. 102 (a)(1) as being anticipated by Kikuna et al.
