The request for foreign priority to a corresponding DE application filed 11/10/22 has been received and is proper. The claim amendment submitted 12/12/24 has been entered, adding claim 17. Claims 1-17 are currently pending yet all are rejected as detailed below. 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 § 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. Corcoran Claim(s) 1-17 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Corcoran et al. (CA 2126335). Corcoran is directed to surface effect dampers. See Abstract. Claim 1: Corcoran discloses a damper apparatus [Figs. 2, 5, 9] for reducing a movement of a second part movable relative to a first part [see page 2c], wherein the damper apparatus comprises the following: a first damper component (30) fixedly connected or connectable to the first part [see page 2c]; a second damper component (20, 12) fixedly connected or connectable to the second part and is movable, at least partially or regionally, relative to the first damper component; and a dampening mechanism (14, 32) arranged between the first and second damper components and configured such that a movement of the second damper component relative to the first damper component is or can be reduced, wherein the dampening mechanism comprises a blade or rib structure (14, 32) connected to the first or second damper component with a plurality of protruding regions, which are elastically deflectable at least partially or regionally in a direction of movement of the first damper component relative to the second damper component; and wherein the dampening mechanism comprises a ridge structure (32, 14) connected to the second or first damper component having at least one tooth or protrusion, wherein, at least in a state in which the second damper component is not moved relative to the first damper component, the at least one tooth or protrusion of the ridge structure is arranged at least partially or regionally in an intermeshing manner between two adjacent protruding regions of the blade or rib structure. See Figs. 2, 5, 9. Claim 2: Corcoran discloses that the at least one tooth or protrusion of the ridge structure is positioned between two adjacent protruding regions of the blade or rib structure such that, upon a movement of the first or second damper component relative to the second or first damper component, at least a portion of the protruding regions of the blade or rib structure is elastically deformed using the at least one tooth or protrusion of the ridge structure while simultaneously converting movement energy into elastic deformation work. See Fig. 2. Claim 3: Corcoran discloses that the at least one tooth or protrusion of the ridge structure (5) is formed from a material that is harder compared to the material of the protruding regions of the blade or rib structure (4). See page 6, lines 1-7. Claim 4: Corcoran discloses that the protruding regions of the blade or rib structure (4), when viewed in a cross-section of the protruding regions, have a geometry that at least partially or regionally tapers in the direction of the ridge structure; and/or wherein the at least one tooth or protrusion of the ridge structure, when viewed in the cross-section of the at least one tooth or protrusion, has a geometry that at least partially or regionally tapers in the direction of the blade or rib structure; and/or wherein the at least one tooth or protrusion of the ridge structure (5) has a shape which, at least regionally, is at least substantially complementary to the shape of the protruding regions of the blade or rib structure. See Fig. 2. Claim 5: Corcoran discloses that the blade or rib structure comprises a blade or rib support (16) which is fixedly connected or connectable to the first or second damper component and the plurality of protruding regions connected to the blade or rib support, wherein the blade or rib support is formed from a material that is harder compared to the material of the protruding regions. See Fig. 2. Note: the limitation concerning injection molding is a method of making, not a structural limitation of the apparatus. Claim 6: Corcoran discloses that in an unloaded state, at least a portion of the protruding regions of the blade or rib structure extends at least substantially in a direction that is at least substantially perpendicular to a direction of movement of the second damper component relative to the first damper component; and/or wherein the at least one tooth or protrusion of the ridge structure extends at least substantially in a direction which is at least substantially perpendicular to the direction of movement of the second damper component relative to the first damper component. See Fig. 2 (e.g., peaks of 14). Claim 7: Corcoran discloses that in an unloaded state, at least a portion of the protruding regions of the blade or rib structure (4) extends at least substantially obliquely in view of a direction that extends perpendicular to a direction of movement of the second damper component relative to the first damper component. See Fig. 2 (e.g., non-peaks of 14). Claim 8: Corcoran discloses that the ridge structure is configured such that, between two adjacent teeth or protrusions of the ridge structure, a plurality of protruding regions of the blade or rib structure are arranged; and/or wherein a number of the protruding regions of the blade or rib structure between two adjacent teeth or protrusions of the ridge structure varies, or a number of the teeth or protrusions of the ridge structure between two adjacent protruding regions of the blade or rib structure (4) varies. See Fig. 2 (between adjacent 32 teeth, either 0 or 1 protruding regions). Claim 9: Corcoran discloses that the first and second damper components are each modular in structure, so that the rib structure and/or the ridge structure are exchangeable as needed and for varying a response behavior and/or a dampening factor of the damper apparatus. See Figs. 2, 5 (sleeve 14 could be replaced). Claim 10: Corcoran discloses that the damper apparatus is configured as a rotary damper [Figs. 8-11], in which the first damper component is configured as a housing part having an inner well region that is at least substantially circular-cylindrical in cross-section, wherein the housing part with the inner well region serves as a blade or rib support, to which or at which the protruding regions of the blade or rib structure are connected or formed, wherein the second damper component comprises a carrier part that is at least substantially circular-cylindrical in cross-section, which forms the ridge structure with the at least one tooth or protrusion and is at least partially or regionally accommodated in the inner well region of the first damper component, in an exchangeable manner such that the carrier part with the ridge structure is rotatable relative to the first damper component, while the at least one tooth or protrusion of the ridge structure (5) is arranged at least partially and/or regionally in an intermeshing manner between two adjacent protruding regions of the blade or rib structure. See Figs. 8-11. Claim 11: Corcoran discloses that the damper apparatus is configured as a rotary damper [see Figs. 8-11], in which the first damper component is configured as a housing part having an inner well region (8) that is at least substantially circular-cylindrical in cross-section, wherein the housing part with the inner well region (8) serves as a carrier part which forms the ridge structure with the at least one tooth or protrusion, wherein the second damper component comprises a blade or rib support that is at least substantially circular-cylindrical in cross-section, to which or at which the protruding regions of the blade or rib structure are connected or formed, wherein the circular-cylindrical blade or rib support with the blade or rib structure is at least partially or regionally accommodated in the inner well region of the first damper component, in an exchangeable manner such that the carrier part with the ridge structure is rotatable relative to the first damper component, while the at least one tooth or protrusion of the ridge structure is arranged at least partially and/or regionally in an intermeshing manner between two adjacent protruding regions of the blade or rib structure. See Figs. 8-11. Claim 12: Corcoran discloses that the first damper component comprises an annular region, which is formed in the circular-cylindrical inner well region such that the inner well region is divided into an outer annular channel and a region that is circular in cross-section and is separated therefrom by the annular region, wherein the teeth or protrusions of the ridge structure are formed on a wall bordering the outer annular channel and on a wall of the annular region facing inward, and wherein the second damper component further comprises an annular blade or rib support, which is arranged so as to complement the outer annular channel of the first damper component in such a way that the annular blade or rib support can be at least partially or regionally accommodated in the outer annular channel of the first damper component, wherein protruding regions of the blade or rib structure are connected or formed to or at the annular blade or rib support on both sides. See Figs. 8-11. Claim 13: Corcoran discloses that the damper apparatus is configured as a linear damper, wherein the first damper component is configured as a cylindrical housing part (30) having a cavity that is at least substantially circular-cylindrical in cross-section, wherein the housing part with the cavity serves as a blade or rib support, to which or at which the protruding regions of the blade or rib structure (32) are connected or formed, wherein the second damper component (20, 12) comprises a piston (12) that dips at least partially or regionally into the cavity of the cylindrical housing part and comprises a piston rod (20) having a first end region at which a carrier part (12) with the ridge structure (14) that is substantially circular-cylindrical in cross-section is arranged or formed, wherein the piston (11) with the carrier part (9) and the ridge structure (5) can be displaced in the longitudinal direction of the cylindrical housing part (10) relative to the cylindrical housing part (10), while the at least one tooth or protrusion of the ridge structure is arranged at least partially and/or regionally in an intermeshing manner between two adjacent protruding regions of the blade or rib structure, wherein the at least one tooth or protrusion of the ridge structure (5) is configured as a helix structure, being formed at least partially or regionally on the lateral surface of the circular-cylindrical carrier part.
