Office Action

§102
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. Priority Benefit of earlier filing date of 04/05/2022 of provisional application No. 63/327,420 is acknowledged as required by 35 U.S.C. 119. 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” (means for”) or another linking word or phrase, such as “configured to” or “so that”; the following is a list of non-structural generic placeholders that may invoke 35 U.S.C. 112(f): "mechanism for," "module for," "device for," "unit for," "component for," "element for," "member for," "apparatus for," "machine for," or "system for."; 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. Claim 1 recites “a keeper control unit configured to have a keeper locked configuration that locks movement of the keeper about the keeper pivot connection with respect to the main body”. The three prong tests are: (A) the claim limitation uses the term “means” or a generic placeholder (unit) (B) the term “means” is modified by functional language (locks movement of the keeper), (C) the term “means” is not modified by sufficient structure, material, or acts for performing the claimed function. The third prong is not met. Because claim is modified with act of controlling the keeper and structure having a keeper locked configuration. Therefore the claim is not being interpreted under 35 U.S.C. 112(f). Claim 19 recites “providing a keeper control unit configured to have a keeper locked configuration that locks movement of the keeper about the keeper pivot connection with respect to the main body”. The three prong tests are: (A) the claim limitation uses the term “means” or a generic placeholder (unit) (B) the term “means” is modified by functional language (locks movement of the keeper), (C) the term “means” is not modified by sufficient structure, material, or acts for performing the claimed function. The third prong is not met. Because claim is modified with act of controlling the keeper and structure having a keeper locked configuration. Therefore the claim is not being interpreted under 35 U.S.C. 112(f). Claim 7 recites “a hook disengage unit configured to have a locked configuration that locks movement of the load arm about the load arm pivot connection with respect to the main body; and the hook disengage unit configured to have an unlocked configuration that allows movement of the load arm about the load arm pivot connection with respect to the main body”. The three prong tests are: (A) the claim limitation uses the term “means” or a generic placeholder (unit) (B) the term “means” is modified by functional language (locks and allows movement of the load arm), (C) the term “means” is not modified by sufficient structure, material, or acts for performing the claimed function. The third prong is not met. Because claim is modified with act of hook disengagement. Therefore the claim is not being interpreted under 35 U.S.C. 112(f). 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.
