[AltContent: textbox (Slide element 12/13 Brake element 202 Biasing arrangement 201 Safety line 3)] PNG media_image1.png 350 546 media_image1.png Greyscale Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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) 36 is/are rejected under 35 U.S.C. 103 as being unpatentable over Brinkmann et al. (Brinkmann) 4,721,182 in view of Castaneda 5,636,704. Brinkmann discloses all of the limitations except for the connection element is an aperture of the tongue. Castaneda teaches it is known to have: 36. wherein the connection element is an aperture (275) of the tongue (235). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention with reasonable expectation of success to have modified Brinkmann to have the connection element is an aperture of the tongue as taught by Castaneda for the purpose of providing a conventional attachment means or location for the tether to the tongue before force removal as described within Brinkmann. Claim(s) 40, 48, 49, and 70 is/are rejected under 35 U.S.C. 103 as being unpatentable over Brinkmann et al. (Brinkmann) 4,721,182 in view of Castaneda 5,636,704. Brinkmann discloses all of the limitations of the claimed invention except for has a gripping surface having one or more gripping projections. Castaneda teaches it is known to have: 40. wherein the arcuate brake structure has a gripping surface having one or more gripping projections (270) configured for contacting the safety line when the brake element (235) is in the second position. 48. wherein the arcuate brake structure has a gripping surface having one or more gripping projections (270) configured for contacting the safety line (Rope) when the brake element is in the second position, and wherein the arcuate slide structure (210) has a smooth sliding surface configured for contacting the safety line in the first position. 49. wherein the arcuate brake structure has a gripping surface having one or more gripping projections (270) configured for contacting the safety line when the brake element is in the second position, and wherein each of the arcuate slide structure (210) has a smooth sliding surface configured for contacting the safety line (Rope) in the first position. 70. wherein, in the second position, a roughened gripping surface (270) of an underside of the arcuate brake structure of the brake element (235) is configured to be engaged with the safety line to prevent the sliding movement of the arcuate slide structure (210) of the slide element (205) along the safety line (rope). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention with reasonable expectation of success to have modified Brinkmann to have included gripping surface having one or more gripping projections on the brake as taught by Castaneda for the purpose of preventing accidental sliding of the safety line providing a friction surface to the brake to resist movement of the brake. Allowable Subject Matter Claims 37, 39, 44, and 45 objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: the closest prior art Brinkmann, Atkinson, or Schmid do not disclose in regards to claim 37, wherein the tongue has an opening configured to receive a fixing connected to the slide element and wherein the fixing delimits movement of the brake element between the first position and the second position. In regards to claim 39 wherein the arcuate brake structure tapers in a direction from the first end toward the second, free end. In regards to claim 44 wherein a slot is defined between the base of the slide element and a free end of each of the arcuate slide structures, and wherein the slot is narrower than a width of the safety line. In regards to claim 45 wherein the brake element and the slide element define a nesting space configured to permit a passage of a second safety line traveller through the nesting space in a direction of travel along the safety line. Response to Arguments Applicant’s arguments with respect to the claim(s) have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument.
