Regarding claim 20 , Di ekmann discloses the smoke generating assembly of claim 1 4 , wherein the leading edge extends along a radial direction (Fig. 4, leading edge of auger 400 extends along a radial direction) . 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. Claims 2-5, 10, 13, and 15-16 are rejected under 35 U.S.C. 103 as being unpatentable over Diekmann . Regarding claim 2, Diekmann does not expressly disclose t he smoke generating assembly of claim 1, wherein the smoking angular position is between about 45 degrees and 135 degrees. However, i t would have been obvious to one having ordinary skill in the art at the effective filing date of the invention to set the smoking angular position between about 45 degrees and 135 degrees , since it has been held that 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. In re Aller, 105 USPQ 233. Regarding claim 3, Diekmann does not expressly disclose t he smoke generating assembly of claim 1, wherein the smoking angular position is about 90 degrees. However, i t would have been obvious to one having ordinary skill in the art at the effective filing date of the invention to set the smoking angular position to about 90 degrees , since it has been held that 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. In re Aller, 105 USPQ 233. Regarding claim 4, Diekmann does not expressly disclose t he smoke generating assembly of claim 1, wherein the non-smoking angular position is between about 180 degrees and 270 degrees. However, i t would have been obvious to one having ordinary skill in the art at the effective filing date of the invention to set the non-smoking angular position between about 180 degrees and 270 degrees , since it has been held that 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. In re Aller, 105 USPQ 233. Regarding claim 5, Diekmann does not expressly disclose t he smoke generating assembly of claim 1, wherein the non-smoking angular position is about 225 degrees. However, i t would have been obvious to one having ordinary skill in the art at the effective filing date of the invention to set the non-smoking angular position to about 225 degrees , since it has been held that 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. In re Aller, 105 USPQ 233. Regarding claim 10, Diekmann does not expressly disclose t he smoke generating assembly of claim 6, wherein the angular position sensor comprises at least one of a magnetic encoder or Hall-effect sensor. However, i t would have been an obvious matter of design choice to utilize a magnetic encoder or a Hall-effect sensor as the angular position sensor , since applicant has not disclosed that these particular sensors solves any stated problem or is for any particular purpose and it appears that the invention would perform equally as well with the angular position sensor of Diekmann . Regarding claim 13, Diekmann does not expressly disclose t he smoke generating assembly of claim 1, wherein a pitch of the auger is equal to a width of a heating block of the smoldering heater. However, i t would have been an obvious matter of design choice to form the auger such that a pitch of the auger is equal to a width of a heating block of the smoldering heater , since such a modification would have involved a mere change in the size of a component. A change in size is generally recognized as being within the level of ordinary skill in the art. In re Rose, 105 USPQ 237 (CCPA 1955). Regarding claim 15, Diekmann does not expressly disclose t he indoor smoker of claim 14, wherein the smoking angular position is between about 45 degrees and 135 degrees. However, i t would have been obvious to one having ordinary skill in the art at the effective filing date of the invention to set the smoking angular position between about 45 degrees and 135 degrees , since it has been held that 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. In re Aller, 105 USPQ 233. Regarding claim 16, Diekmann does not expressly disclose t he indoor smoker of claim 14, wherein the non-smoking angular position is between about 180 degrees and 270 degrees. However, i t would have been obvious to one having ordinary skill in the art at the effective filing date of the invention to set the non-smoking angular position between about 180 degrees and 270 degrees , since it has been held that 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. In re Aller, 105 USPQ 233.
