Office Action

§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 Rejections - 35 USC § 103 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 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claims 1-3, 5-11 and 17-25 are rejected under 35 U.S.C. 103 as being unpatentable over Kraus US6264393 (hereinafter, Kraus) in view of Clarke US6752950 (hereinafter, Clarke), in further view of Lesecq US7553116 (hereinafter, Lesecq). Regarding claim 1, Kraus in the same field of endeavor, teaches a fastener assembly for forming a sealed connection between a first panel and a second panel (see panels 2 and 55 in Figs. 4 and 5a-5b), the fastener assembly (see Figs. 1a-d) comprising: a rigid part component 1 configured to retain the second panel relative to the first panel, wherein the rigid part component comprises a head portion (Head, as indicated in annotated Fig. 1) configured to engage the first panel and a shaft portion 5 extending from the head portion along a longitudinal axis (see Fig. 1 showing central dotted line as a longitudinal axis where shaft extends vertically in downward direction); and The Examiner interprets both, component 15 and component 20, combined in Fig. 1 to be a flexible seal. a flexible seal (Seal, as indicated in annotated Fig. 1) that is integral with the rigid part component and positioned at an interface 14 adjacent the head portion to surround the shaft portion (see Fig. 2), wherein the interface defines a non-circular horizontal cross-section (10, see Figs. 1-2 and 4-5) taken along a cut-line perpendicular to the longitudinal axis (see Fig. 1), Kraus fails to teach wherein the rigid part component is fabricated from a part material and the flexible seal is fabricated from a seal material that is different from the part material. Clarke in the same field of endeavor teaches a fastener device having a fastener portion and integral seal portion of different material (see Abstract). It would have been obvious to one having ordinary skill in the art before the effective filing date of claimed invention to have modified Kraus’ rigid part component to be made from a part material and the flexible seal fabricated from a seal material that is different from the part material, since it has been held to be within the general skill of a worker in the art to select a known material on the basis of its suitability for the intended use as a matter of obvious engineering design choice. It is also common knowledge to choose a material that has sufficient strength, durability, flexibility, hardness, and potential aesthetic, etc., for the application, intended use, and design considerations for that material. MPEP 2144.07. Further, it would have been obvious to one of ordinary skill in the art before the effective filing date of claimed invention to have Kraus’ rigid part component from a part material and the flexible seal fabricated from a seal material as taught by Clarke to have improved advantage of the fastener device and the sealing device, where each component enhances their respective functional purposes (see column 1, lines 55-65). As best understood, Kraus fails to teach wherein an outer contour of the non-circular horizontal cross-section of the interface includes at least one lobe that is tapered. However, Lesecq teaches similar fastener adapted to be fixed in a cavity of predetermined contour, wherein an outer contour of the non-circular horizontal cross-section of the interface 7 includes at least one lobe that is tapered (see tapered interface 7 having lobes in Fig. 4). It would have been obvious to one of ordinary skill in thar art before the effective filing date of claimed invention to have modified the interface of Kraus to have tapered lobe as taught by Lesecq for guided and translational movement of the stem with respect to the second part (see Figs. 3-8). PNG media_image1.png 568 288 media_image1.png Greyscale Annotated Fig. 1 Regarding claim 2, Kraus in view of Clarke, in further view of Lesecq teaches the fastener assembly of claim 1, Clarke further teaches wherein the rigid part component and the flexible seal are fabricated to form the fastener assembly via a two-shot injection process (see Abstract). Regarding claim 3, Kraus in view of Clarke, in further view of Lesecq teaches the fastener assembly of claim 2, wherein Kraus further teaches the rigid part component conforms to and bonds with an inner interface surface of the flexible seal to define the interface. Please refer to Fig. 4 where the rigid part component conforms to and bonds with an inner interface surface of the flexible seal at bonding region between reference numbers 10 and 18. Regarding claim 5, Kraus in view of Clarke, in further view of Lesecq teaches the fastener assembly of claim 4, wherein Kraus further teaches the flexible seal conforms to and bonds with an outer interface surface (10, see Fig. 1) of the rigid part component to define the interface. Regarding claim 6, Kraus in view of Clarke, in further view of Lesecq teaches the fastener assembly of claim 1, but fails to teach wherein the at least one lobe is an arrow. However, the Examiner interprets changes in shape have been established to be obvious to a person of ordinary skill in the art in the absence of a persuasive evidence that the particular configuration was significant. The disclosure does not provide any evidence of criticality of the arrow shaped lobe in the disclosure. Therefore, it would have been an obvious matter of design choice to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the shape of lobe in Kraus to be arrow shape as an obvious change in shape. MPEP 2144.04 (iv)(b). Regarding claim 7, Kraus in view of Clarke, in further view of Lesecq teaches the fastener assembly of claim 6, but fails to teach wherein the at least one lobe is a dovetail. However, it would have been an obvious matter of design choice to have modified the shape of the locking element (10) in Kraus to be a dovetail in order to improve the connection of interface. Therefore, it would have been an obvious matter of design choice to one having ordinary skill in the art before the effective filing date of claimed invention to modify the shape of the locking element to dovetail as an obvious change in shape. Further, modifying the shape of locking element to dovetail improves strength and stability of the interface region preventing the flexible seal from losing its bond with rigid part. Regarding claim 8, Kraus in view of Clarke, in further view of Lesecq teaches the fastener assembly of 6, Lesecq further teaches wherein the at least one lobe forms a longitudinal taper in a direction along the longitudinal axis (see Figs. 1, 4 and 7) Regarding claim 9, Kraus in view of Clarke, in further view of Lesecq teaches the fastener assembly of claim 1, wherein Kraus further teaches the rigid part component is configured to engage the second panel (2, in Fig. 4) via a second fastener component (12, see Fig. 1d) coupled thereto. Regarding claim 10, Kraus in view of Clarke, in further view of Lesecq teaches the fastener assembly of claim 9, wherein Kraus further teaches the second fastener component is a grommet (see Figs. 1 and 4) configured to engage an opening (7, see Fig. 4) formed in the second panel. Regarding claim 11, Kraus in view of Clarke, in further view of Lesecq teaches the fastener assembly of claim 9, wherein the rigid part component is a pin (see Figs. 1-5). The Examiner interprets the rigid part component (1) in Kraus as a pin because installation of the rigid part component is carried out by inserting or applying pressure to the element 1. Regarding claim 17, Kraus in view of Clarke teaches a pin and grommet (P&G) fastener (see Fig. 1) for forming a sealed connection between a first panel and a second panel, the P&G fastener comprising: a grommet (12, see Fig. 1); and a fastener assembly comprising a rigid part component (1, see Fig. 1) and a flexible seal (seal, as indicated in annotated Fig. 1) that is integrally coupled with the rigid part component at an interface (14, see Fig. 2), wherein the rigid part component defines a longitudinal axis (see dotted central line extending vertically in Fig. 1), wherein the flexible seal is fabricated from a first material and the rigid part component is fabricated from a second material that is different from the first material. (Please refer to the rejection and rationale set forth for claim 1 above) wherein the rigid part component configured to retain the second (2, see Fig. 5) panel relative to the first panel (55, see Fig. 5) via the grommet (12), and wherein the interface defines a horizontal cross-section taken along a cut line perpendicular to the longitudinal axis, and wherein an outer contour of the horizontal cross-section of the interface is non-circular and includes one or more dovetails to interlock the flexible seal with the rigid part component. (Please refer to rejection and rationale set forth for claims 1 and 7 above based on Kraus in view of Clarke, in further view of Lesecq.) Regarding claim 18, Kraus in view of Clarke, in further view of Lesecq teaches the P&G fastener of claim 17, wherein the fastener assembly comprises a head portion (Head, as indicated in annotated Fig. 1) configured to engage the first panel (55) and a shaft portion (5, see Fig. 1) extending from the head portion. Regarding claim 19, Kraus in view of Clarke, in further view of Lesecq teaches the P&G fastener of claim 18, wherein the flexible seal is positioned adjacent the head portion to surround the shaft portion (see Figs. 3-4). Regarding claim 20, Kraus in view of Clarke, in further view of Lesecq teaches the P&G fastener of claim 17, wherein the rigid part component and the flexible seal are fabricated to form the fastener assembly via a two-shot injection process. The Examiner interprets the limitations of claim 20 are substantially similar to limitations in claim 2, where Kraus in view of Clarke, in further view of Lesecq still teaches and/or make obvious of the limitations. Please refer to the rejection and rationale set forth for claim 2 above. Regarding claim 21, A fastener forming a sealed connection between a first component and a second component, the fastener comprising: a rigid part component configured to retain the second component relative to the first component, wherein the rigid part component is fabricated from a part material and comprises a head portion configured to engage the first component and a shaft portion extending from the head portion along a longitudinal axis; and a flexible seal that is integral with the rigid part component and positioned at an interface adjacent the head portion to surround the shaft portion, wherein the flexible seal is fabricated from a seal material that is different form the part material, wherein the interface defined a non-circular horizontal cross-section taken along a cut line that is perpendicular to the longitudinal axis. (Please refer to the rejection and rationale set forth above in claim 1 for limitations above based on Kraus in view of Clarke, in further view of Lesecq) Furthermore, Kraus in view of Clarke fails to teach wherein the interface defined an outer contour of the non-circular horizontal cross-section defines four lobes around the longitudinal axis that are configured to interlock the flexible seal with the rigid part component. However, Lesecq further teaches interface 7 may vary in number provided these ribs/interface enable the guiding and annular positioning of the first part with respect to second part (see column 6, lines 18-22). It would have been obvious to one of ordinary skill in the art before the effective filing date of claimed invention to modify interface of Kraus to have four lobes as taught by Lesecq to assist in guiding and positioning of the first part with respect to the second part. Regarding claim 22, Kraus in view of Clarke, in further view of Lesecq teaches the fastener of claim 21, but fails to teach wherein each of the four lobes is a dovetail. However, the Examiner interprets changes in shape have been established to be obvious to a person of ordinary skill in the art in the absence of a persuasive evidence that the particular configuration was significant. The disclosure does not provide any evidence of criticality of the dovetail shaped lobe in the disclosure. Therefore, it would have been an obvious matter of design choice to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the shape of lobe in Kraus to be arrow shape as an obvious change in shape. MPEP 2144.04 (iv)(b). Regarding claim 23, Kraus in view of Clarke, in further view of Lesecq teaches the fastener of claim 21, but fails to teach wherein each of the four lobes is an arrow. However, the Examiner interprets changes in shape have been established to be obvious to a person of ordinary skill in the art in the absence of a persuasive evidence that the particular configuration was significant. The disclosure does not provide any evidence of criticality of the arrow shaped lobe in the disclosure. Therefore, it would have been an obvious matter of design choice to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the shape of lobe in Kraus to be arrow shape as an obvious change in shape. MPEP 2144.04 (iv)(b). Regarding claim 24, Kraus in view of Clarke, in further view of Lesecq teaches the fastener of claim 21, but fails to teach wherein each of the four lobes is a saw-toothed cross. However, the Examiner interprets changes in shape have been established to be obvious to a person of ordinary skill in the art in the absence of a persuasive evidence that the particular configuration was significant. The disclosure does not provide any evidence of criticality of the saw-toothed cross shaped lobe in the disclosure. Therefore, it would have been an obvious matter of design choice to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the shape of lobe in Kraus to be arrow shape as an obvious change in shape. MPEP 2144.04 (iv)(b). Regarding claim 25, Kraus in view of Clarke, in further view of Lesecq teaches the fastener of claim 21, wherein Kraus further teaches rigid part 1 comprises a tree fastener (see rigid part shaped like a tree). Claim 4 is rejected under 35 U.S.C. 103 as being unpatentable over Kraus in view of Clarke, in further view of Lesecq, in further view of Lewis et al., US20080052878 (hereinafter, Lewis). Regarding claim 4, Kraus in view of Clarke in further view of Lesecq teaches the fastener assembly of claim 1, but fails to teach wherein the flexible seal is over-molded onto the rigid part component to form the fastener assembly. The Examiner notes that the instant method step limitations are considered obvious over the prior art in view of rejections of the structural limitations previously set forth. Although the prior art does not explicitly set forth the method steps as claimed when the method step essentially set forth the provision and use of an apparatus, as intended by its structure, then such method steps are considered obvious when the structure of the apparatus has been demonstrated as obvious or anticipated by the prior art. However, Lewis in the same field of endeavor teaches a single piece fastener includes a relatively hard clip and a relatively soft seal where the seal can be overmolded onto the clip (see Abstract). It would have been obvious to one of ordinary skill in the art before the effective filing date of claimed invention to have flexible seal taught by Kraus in view of Clarke, in further view of Lesecq to be over-molded as taught by Lewis for molding of parts in desired orientation to achieve better positional tolerances at the conclusion of forming of the fastener system. Response to Arguments Applicant's arguments filed 08/01/2025 have been fully considered but they are not persuasive. Rejection to claims 1-11 and 17-25 has been established above based on existing and newly found prior art. Please refer to rejection and rationale set forth above. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Hubert et al., (US20140050548) teaches a Fastening Clip, in particular a lining part of a motor vehicle to a body sheet, having an anchor member (12), a locking member (16) and a sealing member (14) in Fig. 1. Bugner (US20080276436) teaches a Device for Connecting a Carrier Part A and an Add-on Piece, where the device includes a receiving part (1), an anchoring part (3) and a connecting part (2).
