Office Action

§102 §103
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: elastic member in claim 1. 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(s) 1-13 is/are objected to because of the following informalities: Claims 1-13 recites “centring” throughout the claims. This is a typographical error and should recite --centering--. Claim 1 recites “respect to a said longitudinal axis” in line 7. The examiner suggests amending to --respect to said longitudinal axis--. Claim 9 recites “configured for guiding said bar along an advancement direction, a movable grasping member that is movable along an advancement direction transversely to said advancement direction” in line 4-7. The examiner suggests amending the limitation to --configured for guiding said bar along a first advancement direction, a movable grasping member that is movable along a second advancement direction transversely to said first advancement direction--. This amendment is suggested in order to avoid confusion and provide clarity in distinguishing the different advancement directions. Appropriate correction is required.

It would have been obvious to one of ordinary skill in the art, before the effective filing date, to modify the advancement device of Burns to include a belt or tape as taught by Goss in order to provide a continuous contact track for supporting the bar along a length of a bar. Claim(s) 10 is/are rejected under 35 U.S.C. 103 as being unpatentable over Horlitz et al. US 5303621 in view of Goss US 9546753. As for claim 10, Horlitz discloses all the limitations as recited above but does not specify wherein said supporting and guiding member and/or said movable grasping member includes a belt or tape element that is wound around a pair of wheels that are spaced and rotatable around respective axes arranged transversely to said advancement direction, said belt or tape element being shaped for coming into contact with the side surface of said bar to perform thereupon the action of dragging along said advancement direction. However, Goss teaches an advancement device having a supporting and guiding member (T2) for receiving a first side of a tube and guiding said tube along an advancement direction and a grasping member (T1) for engaging a second side of a tube opposite a first side and an advancement motor (30) for rotating and supporting the guiding member and/or grasping member wherein said supporting and guiding member and/or said movable grasping member includes a belt or tape (20, 32) element that is wound around a pair of wheels (21) that are spaced and rotatable around respective axes arranged transversely to said advancement direction, said belt or tape element being shaped for coming into contact with the side surface of said tube to perform thereupon the action of dragging along said advancement direction. It would have been obvious to one of ordinary skill in the art, before the effective filing date, to modify the advancement device of Horlitz to include a belt or tape as taught by Goss in order to provide a continuous contact track for supporting the bar along a length of a bar. Claim(s) 10 is/are rejected under 35 U.S.C. 103 as being unpatentable over Turley US 1224046 in view of Goss US 9546753. As for claim 10, Turley discloses all the limitations as recited above but does not specify wherein said supporting and guiding member and/or said movable grasping member includes a belt or tape element that is wound around a pair of wheels that are spaced and rotatable around respective axes arranged transversely to said advancement direction, said belt or tape element being shaped for coming into contact with the side surface of said bar to perform thereupon the action of dragging along said advancement direction. However, Goss teaches an advancement device having a supporting and guiding member (T2) for receiving a first side of a tube and guiding said tube along an advancement direction and a grasping member (T1) for engaging a second side of a tube opposite a first side and an advancement motor (30) for rotating and supporting the guiding member and/or grasping member wherein said supporting and guiding member and/or said movable grasping member includes a belt or tape (20, 32) element that is wound around a pair of wheels (21) that are spaced and rotatable around respective axes arranged transversely to said advancement direction, said belt or tape element being shaped for coming into contact with the side surface of said tube to perform thereupon the action of dragging along said advancement direction. It would have been obvious to one of ordinary skill in the art, before the effective filing date, to modify the advancement device of Turley to include a belt or tape as taught by Goss in order to provide a continuous contact track for supporting the bar along a length of a bar. Claim(s) 12 is/are rejected under 35 U.S.C. 103 as being unpatentable over Horlitz et al. US 5303621 in view of Stuebner US 2657933. As for claim 12, Horlitz discloses an apparatus (1) for feeding a bar (21) to a machine tool spindle (26), including a self-centering device (5) and an advancement device according to claim 9. Horlitz does not specify wherein the self-centering device is according to claim 1. However, Stuebner teaches a self-centering device for feeding a bar to a machine tool according to claim 1. It would have been obvious to one of ordinary skill in the art, before the effective filing date, to substitute the self-centering device of Horlitz with the self-centering device of Stuebner as an alternative self-centering device for feeding a bar to a machining tool.
