Office Action

§102
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 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: “dry air supply device” in claim 5. 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. Claim(s) 1-6 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by DE 4033331 A1 to Ohtani et al. (Ohtani). In reference to independent claim 1, Ohtani discloses: An air purge mechanism (see Fig. 6 or 8), comprising: a plurality of containers accommodating electrical connection parts (motors 207, 210, 211, 268, 269, and 270 or motors 408, 431 and 447); and a cable (323, 328, 333, 337, 338, and 339 or K2, K3, and K4) connecting the containers (see Figs. 6 or 8), wherein one of the containers is provided with an air supply port (via connecting elements 321, 326, 331, and 342) through which compressed air (from compressor 362) is supplied thereto (via valves 358, 359, 360, and 361 and tubes 327, 332, 336, and 357, 353), the cable includes a wire bundle (see Figs. 6, 8, 9, and 10) formed by bundling a group of wires connected to the electrical connection parts, and a sheath covering an exterior surface of the wire bundle (see Figs. 6, 8, and 9), and interior spaces of two of the containers are connected to each other via gaps between the wires inside the sheath (see Figs. 8 and 9, page 10 of the translation “(2) How it works”). In reference to dependent claim 2, Ohtani further discloses: the containers are enclosed containers (see Figs. 1, 2, 5, and 8). In reference to dependent claim 3, Ohtani further discloses: any of the containers not provided with the air supply port is provided with a pressure detection port or a pressure sensor for detecting a pressure inside (all of the motors of the robot of Ohtani is supplied with compressed air, see Fig. 6, and are thus provided with an air supply port). In reference to dependent claim 4, Ohtani further discloses: a dry air supply device (363) connected to the air supply port (see Fig. 6). In reference to claim 5, Ohtani further discloses: A robot (201), comprising: a base (202) fixed to an installation surface; a movable part (203) provided so as to be movable relative to the base (in directions A and B, see Fig. 1); and the air purge mechanism according to Claim l (see rejection above), wherein the one of the containers (207) provided with the air supply port (via connecting element 321, see Fig. 6) is fixed to the base (202) (see Fig. 1), and another of the containers (268, 269, and 270) not provided with the air supply port (via connecting element 342, i.e. that is not connecting element 321, see Fig. 6) is fixed to the movable part (203) (see Fig. 1). In reference to independent claim 6, Ohtani discloses an air purge method performed by the air purge mechanism as recited in claim 1 (see rejection above).
