Office Action

§102 §Other
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, “mechanism”, 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: the “securement mechanism in claim 12 and the attachment mechanism in claim 18. 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 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 1-3, 5-6, 14, and 17 are rejected under 35 U.S.C. 102a1 as being anticipated by Stodulka (US 2020/0307915). In regard to claim 1, Stodulka shows a debris chute assembly with a plurality of wall members 9 that are selectively engageable with a scaffold 21/22/23 (see figure 4). A passageway P is defined in each wall member of the plurality of wall members by the lip 3/7. A portion 21 of the scaffold may be received within the passageway (see the discussion of hanging the wall member from a horizontal member 121 of the scaffold in paragraph 0021 and the annotated figure below). A flange F is provided on at least one wall member 9 of the plurality of wall members. A fastener in the form of a spring loaded catch 19 is provided on the at least one wall member. The flange F is removably secureable to the scaffold 21/23 via the fastener 19 and the corner members 1 shown in figures 1 and 4). In regard to claim 2, the debris chute assembly, the scaffold includes a plurality of standards 23 spaced a distance apart from one another and a plurality of ledgers 21 extending between adjacent standards of the plurality of standards. A ledger 121 of the plurality of ledgers is received within the passageway P. The flange F and a standard 23 of the plurality of standards are removably secureable to one another via the spring loaded catch 19 and the corner member 1. In regard to claim 3, the at least one wall member comprises 9 a wall panel having a top T, a bottom B, and a first side S1 and a second side S2 extending between the top and the bottom. The flange extends outwardly from the first side. It is recognized that the flange F extends inwardly toward the chute, it may still be considered to extend outwardly from the first side S1 in the absence of any claim language defining inward and outward directions relative to the wall member. In regard to claim 5, each wall member 9 includes a wall panel having a top T, a bottom B, a first side S1, and a second side S2 extending between the top T and the bottom B. A connector 3/7 extends outwardly from an outer surface OS of the wall panel proximate the top T. The passageway is defined by the connector 3/7. In regard to claim 6, the fastener 19 extends outwardly from an outer surface of the flange F. In regard to claim 14, it should be noted that the panels 9 may be used on structures of any size (see paragraph 0011). As such, when the panels 9 are mounted on a structure taller than the illustrated structure, it would include 5 or more panels 9. Two of these panels would define a plurality of first wall members, the next two of these panels would define a plurality of second wall members, and the 5th or more panels would define at least one third wall member. In regard to claim 17, the third wall member would define a hopper wall member allowing the chute to be loaded (see the angled position of the panels 9 in figure 4 in which the panels define a “hopper” when the term is given a reasonably broad interpretation). Allowable Subject Matter Claims 18-24 are allowed. Claims 4, 7-13, and 15-16 objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
