Claim Rejections - 35 USC § 103 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. Claim(s) 4 is/are rejected under 35 U.S.C. 103 as being unpatentable over Henderson ( US 4086922) in view of Lee (US 2005/0131320) . In regards to claim 4, Henderson discloses the device of claim 3. Henderson does not disclose wherein the frame is configured to allow a hand of the user to extend through the first opening to grasp the handle with one or more digits of the user extending into the first opening. However, Lee teaches a hand held massage device wherein the frame is configured to allow a hand of the user to extend through the first opening to grasp the handle with one or more digits of the user extending into the first opening (fingers may wrap around handle, Fig 5). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Henderson wherein the frame is configured to allow a hand of the user to extend through the first opening to grasp the handle with one or more digits of the user extending into the first opening as taught by Lee as this would allow the user to have a firmer and more secure grip on the device to ensure comfort and proper application of pressure. Claim(s) 6 and 11 is/are rejected under 35 U.S.C. 103 as being unpatentable over Henderson ( US 4086922). In regards to claim 6, Henderson discloses the device of claim 1. While Henderson does not disclose wherein the handle is positioned closer to the front portion or the rear portion of the frame, as no criticality has been assigned to the exact dimensioning of the device, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Henderson wherein the handle is positioned closer to the front portion or the rear portion of the frame as such minor changes in sizing and relative dimensioning or positioning do not hold patentable weight without evidence that such changes would alter the function of the device (MPEP 2144.04 IV A and MPEP 2144.04 VI C ). In regards to claim 11, Henderson discloses the device of claim 1 and Henderson further discloses wherein the front portion of the frame is open between a first side and a second side(see Annotated Fig 1 and 3), an axle extends between the first side and the second side at the front portion of the frame (axle 20), a first end of the axle is received in a first aperture in the first side of the frame and a second end of the axle is received in second aperture in the second side of the frame (column 3 line 24-27), the roller extending around or integral with the axle (bore 19, column 3 line 23-24). While Henderson does not disclose wherein the axle is rotatable within the first and second apertures, wherein the roller is rotated by the axle during use , it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Henderson to reverse the taught configuration (axle 20 non-rotating, column 3 line 36-37) as such would be an obvious modification as it would not alter the function of the device (MPEP 2144.04 VI A). Claim(s) 10 and 12 is/are rejected under 35 U.S.C. 103 as being unpatentable over Henderson ( US 4086922) in view of Olschansky (US 20 17 / 0231862 ). In regards to claim 10, Henderson discloses the device of claim 9. While Henderson discloses a member at ends of the axle for securing the axle through the first and second apertures of the frame (heads 22 on outside of bores 21 of frame, column 3 line 36-40, Fig 1 and 3), Henderson does not disclose the coupling member being coupled or removed from the end of the axle for interchangeably coupling the roller to the frame. However, Olschansky teaches a massage device where the axle has at least one coupling member being coupled or removed from the end of the axle for interchangeably coupling the roller to the frame (nuts 173 used to secure axle 172, paragraph 58). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Henderson where the axle has at least one coupling member being coupled or removed from the end of the axle for interchangeably coupling the roller to the frame as taught by Olschansky as this would allow the user to alter the configuration of the device or change the roller as needed to meet their needs. In regards to claim 12, Henderson discloses the device of claim 11. While Henderson discloses a member at ends of the axle for securing the axle through the first and second apertures of the frame (heads 22 on outside of bores 21 of frame, column 3 line 36-40, Fig 1 and 3), Henderson does not disclose the coupling member being coupled or removed from the end of the axle for interchangeably coupling the roller to the frame. However, Olschansky teaches a massage device where the axle has at least one coupling member being coupled or removed from the end of the axle for interchangeably coupling the roller to the frame (nuts 173 used to secure axle 172, paragraph 58). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Henderson where the axle has at least one coupling member being coupled or removed from the end of the axle for interchangeably coupling the roller to the frame as taught by Olschansky as this would allow the user to alter the configuration of the device or change the roller as needed to meet their needs. Claim(s) 13 and 14 is/are rejected under 35 U.S.C. 103 as being unpatentable over Henderson ( US 4086922) in view of Dominee (US 2018/0161234 ). In regards to claim 13, Henderson discloses the device of claim 1. Henderson does not disclose wherein the roller has a cylindrical shape. However, Dominee teaches wherein the roller has a cylindrical shape ( massage head may be ball or cylinder , paragraph 29, Fig 5A and 5B ). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Henderson wherein the roller has a cylindrical shape as taught by Dominee as these are known shapes for which to apply massage. In regards to claim 14, Henderson discloses the device of claim 1. Henderson does not disclose wherein the roller includes a plurality of protrusions extending from an outer surface of the roller or the roller includes a middle portion having a larger diameter than the end portions of the roller. However, Dominee teaches wherein the roller includes a plurality of protrusions extending from an outer surface of the roller (Fig 2 and 4A-4B) . Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Henderson wherein the roller includes a plurality of protrusions extending from an outer surface of the roller or the roller includes a middle portion having a larger diameter than the end portions of the roller as taught by Dominee as this would provide additional pressure into muscles (Dominee: paragraph 32).
