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 Status Claims 1-18 are pending. Claims 17-18 are new. Claims 1-5, 7-9, 11-12, and 14-15 have been amended. By virtue of dependency, all dependent claims are also amended in scope. Drawings 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 “main circuit expansion valve circuit” 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) 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. Specification The specification is objected to as failing to provide proper antecedent basis for the claimed subject matter. See 37 CFR 1.75(d)(1) and MPEP § 608.01(o). Correction of the following is required: the originally filed disclosure lacks proper antecedent basis for the newly claimed "main circuit expansion valve circuit." Applicant is encouraged to revert back to the previous terminology. The specification is objected to as failing to provide proper antecedent basis for the claimed subject matter. See 37 CFR 1.75(d)(1) and MPEP § 608.01(o). Correction of the following is required: the claims lack proper antecedent basis for newly claimed “main circuit expansion valve circuit.” The originally filed disclosure is silent on the terminology of “valve circuit.” Further, a separate circuit of valves/valve flow start and stop of fluid flow is not shown nor discussed in the originally filed disclosure. 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 1-18 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. The newly recited “main circuit expansion valve circuit” is not described and is not disclosed in the originally filed disclosure. Under broadest reasonable interpretation, one of ordinary skill in the art/the office uses the plain meaning as required for pending claims. The claims as written at present, necessitates a distinct expansion valve circuit, (i.e. a circuit by definition requires “a path or route that starts and stops in the same place”)1 whereas the originally claimed main circuit expansion device unit was merely defined as a plurality of expansion valves in parallel within the main refrigerant circuit (see paragraph [0009] of the specification of the instant application). Applicant’s original terminology has support in the originally filed disclosure. 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 1-18 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. The newly claimed “main circuit expansion valve circuit” is not described nor shown in the originally filed disclosure. It is unclear which elements would necessarily be included or excluded by the same, as the specification nor drawings show how the refrigerant would pass through a separate valve circuit as circuit implies another fluid flow loop/path/route with travel starting and stopping at the same place after traversing the path. Response to Arguments Applicant’s arguments with respect to claims 1-18 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. In response to applicant's argument that the references fail to show certain features of the invention, it is noted that the features upon which applicant relies (i.e., main expansion valve circuit, as a valve circuit is not properly claimed nor supported) are not recited in the rejected claim(s). Although the claims are interpreted in light of the specification, limitations from the specification are not read into the claims. See In re Van Geuns, 988 F.2d 1181, 26 USPQ2d 1057 (Fed. Cir. 1993). Allowable Subject Matter Claims 1-18 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action. The following is a statement of reasons for the indication of allowable subject matter: the prior art of record does not show nor reasonably suggest, in combination, in a heat pump device, all of a main refrigerant circuit including a main circuit expansion device unit (i.e., which includes expansion valves in parallel configuration having variable degree of opening via a controller), an injection pipe connected between the condenser and the main circuit expansion device, an injection expansion valve, an outside air temperature sensor, a suction pressure sensor, and a controller which are all structurally and operably interconnected as recited in independent claims 1 and 3. To place the application in better condition for allowance, the office recommends applicant reinstate the original language relating to supported “main circuit expansion device unit” throughout the claims. Applicant should also amend the claim language regarding the controller and the controller steps. Applicant is encouraged amend the claim language to have the controller be specifically programmed to perform the controller steps in claims 1 and 3 (i.e. “the controller is programmed to …”) and not have the controller function/step claims be in a wherein clause as configuration, as this type of terminology render the claims to be conditional/contingent/optional limitations. See MPEP 2111.04 II. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Dirth (4,393,662). Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
