Office Action

§102 §112
DETAILED ACTION 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. Claim 14 is rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor, or for pre-AIA the applicant regards as the invention. Regarding claim 14, “The combined plug-socket connector system according to claim 11” is indefinite because claim 11 does not claim a combined plug-socket connector system. Claim 11 claims a connector cable. The limitations of “the second connector socket . . .” lack antecedent basis and are ambiguous as to what they refer to. The limitations of claim 14 are given little weight. IMPROPER MARKUSH GROUPING Claims 2, 4, 5, 8, 9, and 10 are rejected on the basis that it contains an improper Markush grouping of alternatives. See In re Harnisch, 631 F.2d 716, 721-22 (CCPA 1980) and Ex parte Hozumi, 3 USPQ2d 1059, 1060 (Bd. Pat. App. & Int. 1984). A Markush grouping is proper if the alternatives defined by the Markush group (i.e., alternatives from which a selection is to be made in the context of a combination or process, or alternative chemical compounds as a whole) share a “single structural similarity” and a common use. A Markush grouping meets these requirements in two situations. First, a Markush grouping is proper if the alternatives are all members of the same recognized physical or chemical class or the same art-recognized class, and are disclosed in the specification or known in the art to be functionally equivalent and have a common use. Second, where a Markush grouping describes alternative chemical compounds, whether by words or chemical formulas, and the alternatives do not belong to a recognized class as set forth above, the members of the Markush grouping may be considered to share a “single structural similarity” and common use where the alternatives share both a substantial structural feature and a common use that flows from the substantial structural feature. See MPEP § 2117. The Markush groupings of claims 2, 4, 5, 8, 9, and 10 are improper because the alternatives defined by the Markush grouping do not share both a single structural similarity and a common use. The alternatives are have no structural similarities and have different functions. To overcome this rejection, Applicant may set forth each alternative (or grouping of patentably indistinct alternatives) within an improper Markush grouping in a series of independent or dependent claims and/or present convincing arguments that the group members recited in the alternative within a single claim in fact share a single structural similarity as well as a common use. 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 anticipatory rejections under 35 U.S.C. 102 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. Claims 1-10 and 13 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Ishida et al. US 10381778 (“Ishida”). Regarding claim 1, Ishida discloses a combined connector plug 2 (plug 2 is a male connector, col. 4, lines 45-55) for a connection between (i.e., capable of making a connection between) a towing vehicle and a trailer, comprising: a first connector plug portion 55B configured to connect a first connector socket 72B portion and to provide (i.e. capable of providing) a first power supply and low-speed communication (col. 4, lines 1-5, note that the terms “low-speed” and “high speed” are purely relative terms and do not require any absolute values of communication rates) link between the towing vehicle and the trailer; and a second connector plug portion 55C configured to connect a second connector socket portion and to provide (i.e. capable of providing) a second power supply and a high-speed (i.e., a speed higher than a lower speed) communication link between the towing vehicle and the trailer, the high-speed communication link providing a transmission rate that is higher than for the low-speed communication link (note that the transmission rate is determined by a signal transmitter; plug portion 55B is inherently capable of transmitting a signal having a higher or lower rate than a signal transmitted through plug portion 55C, wherein the first connector plug portion 55B is configured to connect the first connector socket portion even when the second connector plug portion 55C is not connected to the second connector socket portion (e.g. when then mating connector does not include a section 72C. Per claim 2, the second connector plug portion 55C comprises one or more of: a second plug body having a front end and a rear end (see e.g. figure 3) . . . . Regarding claim 3, the limitation is given little weight because it modifies a non-essential/optional limitation of claim 2. Per claim 4, the first connector plug portion 55B comprises one or more of: a first plug body with a front end and a rear end (see e.g. figure 3) . . . . Per claim 5 the first connector plug portion comprises one or more of: 2 a first plug body with a front end and a rear end . . . . Per claim 6 the first connector plug portion and the second connector plug portion are spaced from each other, and each comprise a separate moisture protection (hoods 53 of each portion 55B and 55C) to enable a connection of the first connector plug portion with a cable that comprises only a first connector socket portion. Per claim 7, Ishida discloses a combined connector socket (3, socket 3 is a female connector, col. 4, lines 45-55) for a connection between (i.e., capable of making a connection between) a towing vehicle and a trailer, comprising: a first connector socket portion 72B configured to connect a first connector plug portion and to provide a first power supply and low-speed communication link (col. 4, lines 1-5, note that the terms “low-speed” and “high speed” are purely relative terms and do not require any absolute values of communication rates) between the towing vehicle and the trailer; and a second connector socket portion 72C configured to connect a second connector plug portion and to provide a second power supply and a high-speed communication link (i.e., a speed higher than a lower speed) between the towing vehicle and the trailer, the high-speed communication link providing a transmission rate that is higher than the low-speed communication link (note that the transmission rate is determined by a signal transmitter; portion 72B is inherently capable of transmitting a signal having a higher or lower rate than a signal transmitted through portion 72C) wherein the first connector socket portion is inherently configured to connect the first connector plug portion even when the second connector socket portion is not connected to the second connector plug portion. Per claim 8, the first connector socket portion comprises one or more of: a first socket body with a front end and a rear end . . . . Per claim 9, the second connector socket portion comprises one or more of: a second socket body with a front end and a rear end . . . . Per claim 10, the second connector socket portion comprises one or more of: a second socket body with a front end and a rear end. Per claim 13, Ishida discloses a combined plug-socket connector system for connecting (i.e., capable of connecting) a towing vehicle with a trailer, the combined plug-socket connector system comprising: (i) a combined connector plug 2 for a connection between the towing vehicle and the trailer, comprising: a first connector plug portion 55B configured to connect a first connector socket portion and to provide a first power supply and low-speed communication link between the towing vehicle and the trailer; and a second connector plug portion 55C configured to connect a second connector socket portion and to provide a second power supply and a high-speed communication link between the towing vehicle and the trailer, the high-speed communication link providing a transmission rate that is higher than for the low-speed communication link, wherein the first connector plug portion is configured to connect (i.e. capable of connecting) the first connector socket portion even when the second connector plug portion is not connected to the second connector socket portion; and (ii) a combined connector socket 3 for a connection between the towing vehicle and the trailer, comprising: a first connector socket portion 72B configured to connect a first connector plug portion and to provide a first power supply and low-speed communication link between the towing vehicle and the trailer; and a second connector socket portion 72C configured to connect a second connector plug portion and to provide a second power supply and a high-speed communication link between the towing vehicle and the trailer, the high-speed communication link providing a transmission rate that is higher than the low-speed communication link, wherein the first connector socket portion is configured to connect the first connector plug portion even when the second connector socket portion is not connected to the second connector plug portion. Claims 11, 12, and 14 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Leigh et al. US 10741963 (“Leigh”) Regarding claims 11 and 14, Leigh discloses a connector cable, comprising: a cable (plural cables 104 secured by elements 110 are considered to be a “cable”) with a plurality of lines and/or wires; a combined connector plug (plural conjoined connectors 106 form a combined connector plug) arranged at each end of the cable to enable a connection between a towing vehicle and a trailer, wherein each combined connector plug comprises: a first connector plug portion (one or more of connectors 106) configured to connect a first connector socket portion and to provide a first power supply (inherently, any wire of the assembly is capable of transmitting power or signal) and low-speed communication link between the towing vehicle and the trailer; and a second connector plug portion (remaining second connectors 106) configured to connect a second connector socket portion and to provide a second power supply and a high-speed communication link between the towing vehicle and the trailer, the high-speed communication link providing a transmission rate that is higher than for the low-speed communication link (note that any connector 106 is inherently capable of providing a lower or higher transmission rate than another connector 106), wherein the first connector plug portion is configured to connect the first connector socket portion even when the second connector plug portion is not connected to the second connector socket portion. Per claim 12. The connector cable according to claim 11, wherein the plurality of lines or wires, in order to provide the high-speed communication link, include one or more of: a shielded wire, a shielded twisted pair, a coaxial cable, or a twin-axial cable. See figure 4B showing a pair of twin axial cables in each connector 106.
