Office Action

§102 §112
DETAILED ACTION The following is an initial Office Action upon examination of the above-identified application on the merits. Claims 1-29 are pending in this application. 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 . 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. Priority Applicant’s claim for the benefit of a prior-filed application under 35 U.S.C. 119(e) or under 35 U.S.C. 120, 121, 365(c), or 386(c) is acknowledged. Applicant has not complied with one or more conditions for receiving the benefit of an earlier filing date under 35 U.S.C. 371. Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Information Disclosure Statement The examiner has considered the information disclosure statements (IDS) submitted on 7 August 2023. Drawings The drawings are objected to as failing to comply with 37 CFR 1.84(p)(5) because they do not include the following reference sign(s) mentioned in the description: reference number 200 (see page 12 line 15) is not shown in figure 2A. The drawings are objected to as failing to comply with 37 CFR 1.84(p)(5) because they include the following reference character(s) not mentioned in the description: reference number 404 in figure 11 is not mentioned in the description of figure 11. The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, the specific steps of the method illustrated in figure 14 must be shown or the feature(s) canceled from the claim(s). No new matter should be entered. Corrected drawing sheets in compliance with 37 CFR 1.121(d), or amendment to the specification to add the reference character(s) in the description in compliance with 37 CFR 1.121(b) 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. 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. Specification The disclosure is objected to because of the following informalities: “HVAC block” should be “HVAC device block” (several occurrences), reference characters “301” and “303” have both been used to designate second add-on HVAC block (see page 25 lines 3, 4-5 and 8, 10), and reference number 220 (see page 26 line 9) is not shown figure 10. Appropriate correction is required. The specification is generally narrative, failing to conform with current U.S. practice. It appears to be a literal translation into English from a foreign document and are replete with grammatical and idiomatic errors. Claim Objections Claims 4, 6 and 18 are objected to because of the following informalities: “HVAC block” should be “HVAC device block”. Appropriate correction is required. Claim 29 is objected to because it is unclear if claim 29 is intended to be dependent on claim 1, or if it is meant to be an independent claim reciting the same limitations as claim 1. If claim 29 is dependent on claim 1, then it creates an insufficient antecedent basis for the dependency due to claim 1 being directed to a HVAC field device, while claim 29 is directed to a method that comprises a service device, a first add-on HVAC device block, a first NFC antenna, and a base HVAC device block. If claim 29 is intended to be an independent claim, then the inclusion of the limitations of claim 1 should be made by amending claim 29 to directly recite the desired limitations as disclosed by claim 1 instead of merely referencing the claim. Examiner is interpreting claim 29 as an independent claim. Appropriate correction is required. 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 12, 13 and 26 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 12 recites the limitation “the external service device” in lines 2-3. There is insufficient antecedent basis for this limitation in the claim. Claim 13 recites the limitation “the base NFC antenna” in lines 1-2. There is insufficient antecedent basis for this limitation in the claim. Regarding claim 26, the phrase “such as” renders the claim indefinite because it is unclear whether the limitations following the phrase are part of the claimed invention. See MPEP § 2173.05(d). The claims are generally narrative and indefinite, failing to conform with current U.S. practice. They appear to be a literal translation into English from a foreign document and are replete with grammatical and idiomatic errors. Claim Rejections - 35 USC § 102 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 – (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. (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. Claim(s) 1-12, 14-19, 21-24 and 26-29 is/are rejected under 35 U.S.C. 102(a)(1)/102(a)(2) as being anticipated by US 20150362928 A1 (US 10261530 B2) to SCHMIDLIN et al.
