Office Action

§102 §112
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 Status This Office action is in response to the filing of 6/20/2025. Claims 1-16 are currently pending. 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: The “driver blade guide” in claims 1 and 16 and corresponding to element 110 which comprises ledges 112, shoulders, 116, and engagement surface 130. 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 Objections Claim 1 is objected to because of the following informality: line 9 reads “a connected a” when it should read “a connected.” Appropriate correction is required. Claim 15 is objected to because of the following informality: line 2 reads “blade guide” when it should read “driver blade guide.” 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. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1-16 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Regarding claims 1 and 16, the limitation “the lead fastener” in line 7 (claim 1) and line 6 (claim 16) lacks sufficient antecedent basis. In order to further prosecution, the limitation has been interpreted to recite “a lead fastener.” Claims 2-15 are rejected based on their dependency from claim 1. Regarding claim 9, the limitation “a nose door” in line 1 is indefinite because it is not clear if the limitation is referring to a new door or the door recited in claim 1. In order to further prosecution, the limitation has been interpreted to be referring to the door recited in claim 1. Regarding claim 16, the limitation “from an extended position” is indefinite because it doesn’t have a corresponding position that the driver member goes to. Since the last line recites “the home position” which lacks sufficient antecedent basis, it appears that applicant intended to have the driver member be configured for movement between an extended position and a home position. In order to further prosecution, this is how the limitation is being interpreted. 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. Claims 1-5, 7, 9-12, and 15-16 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Hung (US 2019/0077000 A1). Regarding claim 1, Hung discloses a tool comprising: a housing (see annotated Fig. 1 below) having a drive channel (as can be seen in Fig. 1 there is channel in which driver member 23 travels); a nosepiece assembly (300 – Fig. 1) connected to a forward end of the housing and having a nose portion (32 – Fig. 2) that extends in a longitudinal direction and a door (311 – Fig. 4) pivotably connected to the nose portion (see Fig. 4); a driver member (the assembly of 22 and 23 – Fig. 1) provided in the housing and configured for movement within the drive channel from an extended position (the position of the assembly of 22 and 23 in Fig. 7) to drive a lead fastener through the nosepiece assembly and into a workpiece during a drive stroke (para. 0038) to a returned position and a home position (the position of the assembly of 22 and 23 in Fig. 5) during a return stroke (para. 0039), the driver member having a driver body (22 – Fig. 1) and a connected driver blade (23 – Fig. 1) configured to contact a head portion of the lead fastener (para. 0038); and a driver blade guide (see annotated Fig. 2 below) mounted to the nose portion and configured to engage the driver blade when the driver member is in the home position (see annotated Fig. 1 below). Annotated Fig. 1 PNG media_image1.png 550 756 media_image1.png Greyscale Annotated Fig. 2 PNG media_image2.png 340 440 media_image2.png Greyscale Hung further discloses: Claim 2, the driver blade (23 – Fig. 1) is connected to the driver body (22 – Fig. 1) at a proximal end and comprises a tip portion (the left end of 23 – Fig. 1) at a distal end (see Fig. 1, 23 is connected to 22 at the right end and has a tip at the left end), and wherein the driver blade guide (see annotated Fig. 2 above) is configured to engage the tip portion of the driver blade when the driver member is the home position (see annotated Fig. 1 above). Claim 3, the driver blade guide (see annotated Fig. 2 above) is stationary (based on the disclosure it is clear that the driver blade guide does not move relative to 100). Claim 4, the driver blade guide (see annotated Fig. 2 above) is disposed on the nose portion (32 – Fig. 2) of the nosepiece assembly (as can be seen in annotated Fig. 2 above, the driver blade guide is disposed on 32). Claim 5, the nose portion (32 – Fig. 2) comprises a pair of flanges (322 – Fig. 2) projecting orthogonally with respect to a longitudinal direction on opposite lateral sides of the nose portion (see Fig. 2, 322 project up orthogonal to the longitudinal direction which runs proximal to distal). Claim 7, the driver blade guide (see annotated Fig. 2 above) comprises an engagement surface (as seen in annotated Fig. 1 above, the upper surface of the driver blade guide engages the tip of 32) that engages the tip of the driver blade. Claim 9, the nose door (311 – Fig. 4) is pivotably disposed on the nose portion (32 – Fig. 2) to have an open position (the position of 311 depicted in Fig. 4) and a closed position (the position of 311 depicted in Fig. 1). Claim 10, the driver blade guide (see annotated Fig. 2 above) has a bifurcated body (as can be seen in Fig. 2, the driver blade guide has a left and a right portion separated by a channel, similar to applicant’s driver blade guide). Claim 11, the bifurcated body comprises a pair of shoulders (see annotated Fig. 2 above, the two projections having an aperture) that pivotably support the nose door (311 – Fig. 4) on the nose portion (see Fig. 4). Claim 12, the driver blade guide (see annotated Fig. 2) comprises axially aligned shoulder apertures (see annotated Fig. 2 above, the apertures in the 2 projections on the driver blade guide) through the pair of shoulders (see annotated Fig. 2 above, the two projections having an aperture) for mounting a pivot pin (see Fig. 2, there is an unlabeled pivot pin that is indicated as inserted through the apertures) of the nose door (see Fig. 4). Claim 15, in both the open position (the position of 311 depicted in Fig. 4) and the closed position (the position of 311 depicted in Fig. 1), the driver blade guide (see annotated Fig. 2 above) remains engaged with the tip of the driver blade (see annotated Fig. 1 above, 23 rests on the driver blade guide, hence it remains engaged whether the nose door is in the open position or the closed position). Claim 16, this claim recites materially the same limitations as those above and is rejected in the same manner. Allowable Subject Matter Claims 6, 8, and 13-14 would be allowable if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action and to include all of the limitations of the base claim and any intervening claims. Regarding claims 1 and 13, Hung does not disclose flanges on the nose portion between which the driver blade guide is disposed. Regarding claim 8, the engagement surface does not have projections that extend into grooves on the nose door side of the driver blade.
