Office Action

§102 §103 §112
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 . Objections 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: claims 9 and 16 call for a first rib and a second rib which are not found/described in the specification; in addition, claim 25 further calls for the first rib extends above the recessed surface from each of the first sidewall and the back wall, (similar for the second rib), they are not described in the specification. 35 U.S.C. 112(a) Rejections Claims 1-27 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. See below explanation. Claims 1-27 rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the enablement requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to enable one skilled in the art to which it pertains, or with which it is most nearly connected, to make and/or use the invention. Claim 1: the newly amended feature: “the frame extends above an upper-most surface and the housing and below a lower-most surface of the housing”. The original disclosure 0039 and 0043 mentioned “frame 20” when describing the power unit 10, this is shown in figs. 11-19 and described in paragraphs 0038 to 0043. The housing is identified as housing 32, the “upper surface” is element 12 (note: the term “upper-most” surface is not used), it appears that element 12 might be considered upper most surface, the frame 20 is clearly not above this upper surface 12 on fig. 11, not to mention that there is no description of the lower-most surface, therefore, it is considered as a new matter under 112(a) and also fails the enablement requirement under 112(a) as the disclosure fails to demonstrate how the frame is above the upper most surface. 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, claim-1: the frame extends above an upper-most surface and the housing and below a lower-most surface of the housing; claim-26: latch recess and latch 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 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(s) 1-7, 9-13, 15-16 and 18-27 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Fleischmann (US 2017/0165828).

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. Claim(s) 8, 14 and 17 are rejected under 35 U.S.C. 103 as being unpatentable over Fleischmann (US 2017/0165828) in view of Brown (US 2010/0231161). Regarding clam 8, 14 and 17, Fleischmann shows the power supply unit (Fleischmann’s figs. 1-3) comprising the power outlet (94) configured to provide alternating current (AC) electricity (¶0090: AC), the power supply unit (figs. 1-3) comprising a second power outlet (72) configured to provide direct current (DC) electricity (¶0100: DC … into the bus lines 70a via the feed-in interface 72). Fleischmann differs from the claimed invention in that it does not explicitly show that the second power outlet is a USB compatible outlet. However, Fleischmann’s second power outlet (72) is configured to provide direct (DC) electricity (¶0100). Brown, in the same field of transport container as Fleischmann, teaches providing a container (i.e. fig. 1) having a power outlet which is USB [Brown: fig. 1, ¶0026: USB (Universal Serial Bus) interfaces 122b] compatible outlet. Hence, it would have been obvious for one skilled in the art before the effective filing data of the application to modify Fleischmann with a USB compatible outlet to provide DC electricity as taught by Brown, because the concept of providing DC electricity from the container to power electrical devices is already taught by Fleischmann, and the use of USB outlet on Fleischmann’s and Brown’s container is dictated by the devices being stored in the container. In other words, this can be considered as an intended use of Fleischmann’s and Brown’s container in relation to devices which require UBS ports in order to receiver power from the container (see Brown ¶ 0003 ) . Response to Arguments On pages 8 and 11 of applicant’s arguments, applicant argues that Fleischmann stack elements 22 and 24 disclose no first rib and second rib. The examiner disagrees. First, applicant’s disclosure doesn’t have a clear description about the first and second ribs. Second, from Fleischmann’s fig. 2, the claimed recessed surface can be mapped onto Fleischmann’s recessed surface of stacks 21 and 24 which receive another stack 22; then the claimed first and second ribs can be mapped onto coupling components (receptacles 92), noted that based on the positions of Fleischmann’s abutments 48, , 50, 52 and 53 which are coupled to their respective receptacles or ribs 92, these receptacles/ribs 92 on Fleischmann are above the recessed surface. Therefore, these claimed features are met. On pages 9-12, applicant argues about “the frame”. The examiner disagrees. First, the amended “frame extends above an upper-most surface…” might potentially create a 112(a) issues, see 112 rejections above. Second, the claimed frame is mapped and explained in details on the current102 rejection above, see comments and annotations on Fleischmann’s fig. 2 above. The Fry reference is currently removed from the rejections.
