Regarding claim 7, the safety bar as claimed in claim 1 wherein the brackets and elongated bar are all manufactured from metal (see col. 3, lines 31+). Regarding claim 8, the safety bar as claimed in claim 7 wherein the metal is aluminum (see col. 3, lines 60+). 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) 5 is/are rejected under 35 U.S.C. 103 as being unpatentable over Micciche. Micciche teaches all of the limitations as discussed regarding claim 1 above except for the specific of the overall length of the safety bar is 3 ½ feet to 7 feet. Micciche teaches the bar extending between vertical walls of a bathtub such as shown in Fig. 1, wherein the length of a bathtub is well-known to have an overall length of between 3 ½ feet to 7 feet. It would have been obvious to one having ordinary skill in the art at the time the invention was effectively filed to make the Micciche’s bar to have an overall length of 3 ½ feet to 7 feet, since it has been held where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art. Claim(s) 7-9 is/are rejected under 35 U.S.C. 103 as being unpatentable over Micciche in view of US 2012/0110729 (hereinafter Baines). Micciche teaches all of the limitations as discussed regarding claim 1 above except for the brackets and elongated bar are all manufactured from metal. Baines teaches the equivalent alternative suitable material such as metal or plastic which include stainless steel and aluminum (see para. [0021], last 5 lines). Accordingly, it would have been obvious to one of ordinary skill in the art at the effective filing date of the claimed invention to have replaced the material of the brackets and elongated bar of Micciche with a metal (claim 7) such as aluminum (claim 8) or a stainless steel (claim 9) as taught by Baines, wherein doing so would merely be substituting equivalents known for the same purpose. An express suggestion to substitute one equivalent component or process for another is not necessary to render such substitution obvious. In re Fout, 675 F.2d 297, 213 USPQ 532 (CCPA 1982). See MPEP 2144.06. Claim(s) 10 is/are rejected under 35 U.S.C. 103 as being unpatentable over Micciche in view of US 4,361,914 (hereinafter Oliver). Micciche teaches all of the limitations as discussed regarding claim 1 above except for the adjustability of the elongated bar is two slidable bars, one within the other. Attention is directed to the Oliver reference which teaches an analogous elongated bar that is adjustable from sections (see Fig. 3) that similar to Micciche or from two slidable bars (127, 129), one within the other (see Fig. 2). Accordingly, it would have been obvious to one of ordinary skill in the art at the effective filing date of the claimed invention to have replaced the two sections of Micciche with two slidable bars, one within the other as taught by Oliver, wherein doing so would merely be substituting equivalents known for the same purpose. An express suggestion to substitute one equivalent component or process for another is not necessary to render such substitution obvious. In re Fout, 675 F.2d 297, 213 USPQ 532 (CCPA 1982). See MPEP 2144.06. Claim(s) 11 and 12 is/are rejected under 35 U.S.C. 103 as being unpatentable over Micciche in view of Baines, as applied to claim 9 above, and further in view of US 4,944,478 (hereinafter Sullivan). Regarding claim 11, Micciche and Baines teach all of the limitations as discussed regarding claim 9 above except for a set screw for joining the two slidable bars to enable adjustability. Attention is directed to the Sullivan reference which teaches an analogous elongated bar that is adjustable from two slidable bars (11, 12), one within the other (see Figs. 2-3) and further comprising a set screw (24) for joining the two slidable bars to enable adjustability. Accordingly, it would have been obvious to one of ordinary skill in the art at the effective filing date of the claimed invention to have replaced the adjustable two sections of Micciche with two slidable bars further comprising a set screw for joining the two slidable bars to enable adjustability as taught by Sullivan, wherein doing so would merely be substituting equivalents known for the same purpose. An express suggestion to substitute one equivalent component or process for another is not necessary to render such substitution obvious. In re Fout, 675 F.2d 297, 213 USPQ 532 (CCPA 1982). See MPEP 2144.06. Regarding claim 12, Micciche and Baines teach all of the limitations as discussed regarding claim 9 above except for a spring-loaded bolt for joining the two slidable bars to enable adjustability. Attention is directed to the Sullivan reference which teaches an analogous elongated bar that is adjustable from two slidable bars (11, 12), one within the other (see Figs. 2-3) and further comprising a spring-loaded bolt (27) for joining the two slidable bars to enable adjustability. Accordingly, it would have been obvious to one of ordinary skill in the art at the effective filing date of the claimed invention to have replaced the adjustable two sections of Micciche with two slidable bars further comprising a spring-loaded bolt for joining the two slidable bars to enable adjustability as taught by Sullivan, wherein doing so would merely be substituting equivalents known for the same purpose. An express suggestion to substitute one equivalent component or process for another is not necessary to render such substitution obvious. In re Fout, 675 F.2d 297, 213 USPQ 532 (CCPA 1982). See MPEP 2144.06. Claim(s) 5 is/are rejected under 35 U.S.C. 103 as being unpatentable over Cohen. Cohen teaches all of the limitations as discussed regarding claim 1 above except for the specific of the overall length of the safety bar is 3 ½ feet to 7 feet. Cohen teaches the bar extending between vertical walls and it can be cut to a desired length during installation (see col. 4, lines 5-17). It would have been obvious to one having ordinary skill in the art at the time the invention was effectively filed to make the Cohen’s bar to have an overall length of 3 ½ feet to 7 feet, since it has been held where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art. Claim(s) 9 is/are rejected under 35 U.S.C. 103 as being unpatentable over Cohen in view of US 2012/0110729 (hereinafter Baines). Cohen teaches all of the limitations as discussed regarding claim 1 above except for the metal is stainless steel. Baines teaches the equivalent alternative suitable material such as metal or plastic which include stainless steel and aluminum (see para. [0021], last 5 lines). Accordingly, it would have been obvious to one of ordinary skill in the art at the effective filing date of the claimed invention to have replaced the metal of Cohen with a stainless steel as taught by Baines, wherein doing so would merely be substituting equivalents known for the same purpose. An express suggestion to substitute one equivalent component or process for another is not necessary to render such substitution obvious. In re Fout, 675 F.2d 297, 213 USPQ 532 (CCPA 1982). See MPEP 2144.06. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
