As to claim 26, Oezcan discloses the brake assembly according to claim 16. Oezcan fails to disclose wherein the spring part includes a plurality of axial bends. Grauss discloses wherein the spring part includes a plurality of axial bends (Fig. 3). PNG media_image13.png 285 392 media_image13.png Greyscale Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to provide the assembly of Oezcan with wherein the spring part includes a plurality of axial bends, to increase the amount of axial tension in the spring. Claims 32 is rejected under 35 U.S.C. 103 as being unpatentable over Oezcan, and in view of Fischer (EP 1004788). As to claim 32, Oezcan discloses the brake assembly according to claim 16. Ozecan fails to disclose wherein at least one groove wall of the annular groove has a circular section. Fischer discloses wherein at least one groove wall of the annular groove has a circular section (Fig. 2) PNG media_image14.png 476 366 media_image14.png Greyscale Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to provide the assembly of Oezcan with wherein at least one groove wall of the annular groove has a circular section, to reduce stress concentration associated with v- shaped or rectangular grooves. Claim 33 is rejected under 35 U.S.C. 103 as being unpatentable over Oezcan, and in view of Fichtner (WO 2022200037). As to claim 33, Ozecan discloses the brake assembly according to claim 16, wherein the shaft is rotatably mounted relative to a body (Para 0046), an armature disk is arranged axially between the body and the brake-lining carrier (Fig. 2), the armature disk is connected to the body for conjoint rotation (Fig. 2), spring elements supported on the body press onto the armature disk (Fig. 1), and the brake-lining carrier is axially arranged between the armature disk and a friction surface (Fig. 1).
