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 and 11 are rejected under 35 U.S.C. 103 as being unpatentable over Kolb. Regarding claim 4, Kolb discloses the system of claim 2, wherein the user interface comprises a first switch and a second switch (Paragraph 48, switches), but fails to disclose wherein the first user input is based on the user adjusting a position of the first switch and the second user input is based on the user adjusting a position of the second switch. Kolb discloses that a system may be optimized to provide for input as desired, and lists the use of switches as an option (Paragraphs 40 and 48). It would have been obvious matter of design choice to one having ordinary skill in the art before the effective filing date of the claimed invention to provide wherein the first user input is based on the user adjusting a position of the first switch and the second user input is based on the user adjusting a position of the second switch, as Applicant has not disclosed that the structure is for a stated purpose or solves a stated problem, and it appears the device would perform equally well as disclosed. Regarding claim 11, Kolb discloses the method of claim 10, wherein the user interface comprises a first switch and a second switch (Paragraph 48, switches), but fails to disclose the method further comprising receiving the first user input in response to the user adjusting a position of the first switch; and receiving the second user input in response to the user adjusting a position of the second switch. Kolb discloses that a system may be optimized to provide for input as desired, and lists the use of switches as an option (Paragraphs 40 and 48). It would have been obvious matter of design choice to one having ordinary skill in the art before the effective filing date of the claimed invention to provide the method including receiving the first user input in response to the user adjusting a position of the first switch; and receiving the second user input in response to the user adjusting a position of the second switch, as Applicant has not disclosed that the structure is for a stated purpose or solves a stated problem, and it appears the device would perform equally well as disclosed.
