Office Action

§102 §103 §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 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. Claim 6 is 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 6 recites the limitation "the charging station" in line 1. There is insufficient antecedent basis for this limitation in the claim. 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: “system for electrically charging” in claim 1 and “unit for” in claim 2. 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. Claim Rejections - 35 USC § 102 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. 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. Claims 1-4 and 6-9 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by McCluskey et al. US 20130002198 (hereinafter McC). With regards to claim 1 McC discloses, A device in the form of a mobile trailer [figs 1-2 mobile unit 102], comprising: an electrical charging system for electrically charging a drive battery [fig 1 system 100 charges batteries 133] of an electrically driven mobile work machine [vehicle 110]; wherein the mobile trailer can attach to a towing vehicle [fig 2 hauling vehicle 124]. With regards to claim 2 McC discloses, The device of claim 1, further comprising a coupling unit for coupling to the towing vehicle [fig 2 and 6 the coupling being the connecting portion of the trailer and towing vehicle which is in fig 2 and can be seen to the right side of fig 6]. With regards to claim 3 McC discloses, The device of claim 1, further comprising a platform for carrying at least one electrically driven mobile work machine [fig 2 and 6 bed 114]. With regards to claim 4 McC discloses, The device of claim 1, wherein the electrical charging system has at least one charging station for electrically charging a drive battery of the electrically driven mobile work machine [fig 2 electrical generation apparatus 104]. With regards to claim 6 McC discloses, The device of claim 1, wherein the charging station has a charging cable [fig 1 and 3 charging cable 106] for electrically charging a drive battery [battery 133] of the electrically driven mobile work machine [vehicle 110]. With regards to claim 7 McC discloses, The device of claim 1, wherein the electrical charging system has at least one current storage unit [batteries 133 within rack 164] which is electrically connected to at least one charging station via an electrical connection [fig 1 station 104 connected via cable 106 to rack 164/batteries 133]. With regards to claim 8 McC discloses, The device of claim 7, wherein the current storage unit is arranged removably on the device [fig 1 batteries 133 and ¶27 “spare rechargeable batteries”]. With regards to claim 9 McC discloses, The device of one of claim 1, wherein the charging station and the current storage unit each have a current interface for receiving electrical energy [fig 1 input end 130, leads 140/142, tie downs 106]. Claim Rejections - 35 USC § 103 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. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claims 5 and 10 are rejected under 35 U.S.C. 103 as being unpatentable over McCluskey et al. US 20130002198 (hereinafter McC) in view of Neligan et al. US 20230011299 (hereinafter Nel). With regards to claim 5 McC fails to disclose, The device of claim 4, further comprising a maneuverable moving apparatus for moving the charging station from its transport position on the mobile trailer into a different position outside the mobile trailer. However, Nel discloses, a maneuverable moving apparatus for moving the charging station from its transport position on the mobile trailer into a different position outside the mobile trailer [fig 1 transport truck 3 lifting mechanism 4 which moves the charging stations 2-1/2-2/2-3]. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the charging systems of McC with Nel to include a moving apparatus to move the charging stations in order to improve the user experience by allowing the stations to be placed in certain areas off of the trailer to provide charging. With regards to claim 10 the combination discloses, The device of claim 1, further comprising a control system for controlling the operation of the electrical charging system [Nel fig 3 and fig 12 charging control unit 2H].
