Para [0094]; The bending section 220 is bent in four directions.). 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim(s) 7, 15 is/are rejected under 35 U.S.C. 103 as being unpatentable over Onuki (US 20130184528) in view of Fancher (US 20220151463). Regarding claim 7, Onuki does not expressly disclose a first brake for selectively preventing rotation of the first control assembly and a second brake for selectively preventing rotation of the second control assembly. Fancher is directed to a medical instrument system (abstract) and teaches a first brake for selectively preventing rotation of the first control assembly and a second brake for selectively preventing rotation of the second control assembly (Reusable hand-piece can include a brake that applies an adjustable level of rotational resistance to the articulation control (e.g., articulation control knobs; FIGS. 11, 13; Para [0270], [0280], [0283], [0407]). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Onuki to include brakes with the drums so that the rotation of the control assembly (wheels) could be smoothly controlled. Regarding claim 15, Onuki does not expressly disclose a first brake for selectively preventing rotation of the first control assembly and a second brake for selectively preventing rotation of the second control assembly. Fancher is directed to a medical instrument system (abstract) and teaches a first brake for selectively preventing rotation of the first control assembly and a second brake for selectively preventing rotation of the second control assembly (Reusable hand-piece can include a brake that applies an adjustable level of rotational resistance to the articulation control (e.g., articulation control knobs; FIGS. 11, 13; Para [0270], [0280], [0283], [0407]). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Onuki to include brakes with the drums so that the rotation of the control assembly (wheels) could be smoothly controlled.
