Office Action

§102 §103
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 . 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 “port for attachment of a data and/or power connection to the chassis module” (Claim 20, ln. 8), “first protrusion” (Claim 15, ln. 2), “first clip mechanism of the spine” (Claim 15, ln. 3), “second protrusion” (Claim 15, ln. 5), “second clip mechanism of the spine” (Claim 15, ln. 6) 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. 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.

Claim Rejections - 35 USC § 103 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 3-4 are rejected under 35 U.S.C. 103 as being unpatentable over Candelora in view of Mascarenhas et al. (US 20190140439 A1, and Mascarenhas hereinafter). Regarding Claim 3, Candelora discloses the chassis module of claim 1 but does not explicitly disclose a port for attachment of a data and/or power connection to the chassis module. Mascarenha discloses a chassis module comprising a port (62, figs. 5 and 10) for attachment of a data and/or power connection to the chassis module (“transmit operating conditions data stored on the memory device to analysis device 44 through communications port 62”, [0041). It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the chassis module of Candelora to incorporate the teachings of Mascarenha so that it further comprises a port for attachment of a data and/or power connection to the chassis module, in order to send information about the operating conditions to external analysis devices (“the processing device operable to collect operating conditions data from the circuit protection device, the operating conditions data including the sensed operating conditions and a trip indication that indicates whether the circuit protection device has opened the at least one current path”, Abstract section of Mascarenhas). Regarding Claim 4, Candelora/Mascarenhas discloses the chassis module of claim 3, wherein the port is accessible for attachment of the data and/or power connection after the chassis module is at the receiving compartment (fig. 10 of Mascarenhas). Claim 20 is rejected under 35 U.S.C. 103 as being unpatentable over Hancock in view of Mascarenhas. Regarding Claim 20, Hancock discloses a chassis module (including 34 and 36, figs. 1-2) configured for installation at any of a plurality of receiving compartments of a spine of a chassis (fig. 1: regions where instances 34 and 36 are inserted), the spine comprising two bus bars (fig. 4: busbars 46 and 50 corresponding to A and C phases), the chassis module comprising: two bus bar contacts on a bottom of the chassis module (fig.2: portion of 34 corresponding to 182 and 186 of fig. 18, in view of “182 for direct attachment of the A-phase load terminal of a main breaker… B and C phases also have respective holes 184 and 186 for attachment thereto of the respective B- and C-phase load terminals of the main breaker with fasteners 188.”, Col. 8, ln. 25-32), where each of the two bus bar contacts physically contact the corresponding bus bar of the spine (Col. 8, ln. 25-32), and the bus bar contacts and the bus bars have hole patterns for attachment of the chassis module to the spine at the receiving compartment (figs. 2 and 18). Hancock does not explicitly discloses a port for attachment of a data and/or power connection to the chassis module. Mascarenha discloses a chassis module including a port (81, fig. 8) for attachment of a data and/or power connection to the chassis module (figs. 4 and 8 and “First communications port 81 … communicatively coupled to the processing unit … operable to transmit operating conditions data to analysis device 44”, [0048]). It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the device of Hancock to incorporate the teachings of Mascarenha so that it further comprises a port for attachment of a data and/or power connection to the chassis module, in order to send information about the operating conditions to external analysis devices (“the processing device operable to collect operating conditions data from the circuit protection device, the operating conditions data including the sensed operating conditions and a trip indication that indicates whether the circuit protection device has opened the at least one current path”, Abstract section of Mascarenhas).
