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) 4, 8, and 11 are as best understood and is/are rejected under 35 U.S.C. 103 as being unpatentable over Kane (US 2017/0258134). As per claim 4: Kane discloses the cartridge 70, and the airflow restrictor 33. However, Kane does not explicitly disclose wherein the airflow restrictor is between the vapor generator and the discharge end of the dilution air passage. On the other hand, Kane showed the airflow restrictor is located between the vapor generator and the first air inlet. However, a person having ordinary skill in the art would know that having the airflow restrictor at a designated areas can only deal with location of parts because such modification still would not change the function of the cartridge after all but to further enhance the flowing of aerosol within the cartridge to the discharge end as the manufacture desire. Since, it has been held that rearranging parts of an invention involves only routine skill in the art. In re Japikse, 86 USPQ 70. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claim invention to further modify the cartridge of Kane by having the airflow restrictor is between the vapor generator and the discharge end of the dilution air passage as taught by the instant invention to further enhance the flowing of aerosol within the cartridge to the discharge end as the manufacture desire. As per claim 8: Kane discloses the cartridge 70, wherein the air passage 20 and the dilution air passage 54 are sized to provide a first expected volumetric airflow rate through the air passage 20. However, Kane does not disclose wherein a second expected volumetric airflow rate through the dilution air passage that is in a ratio of about 60:40 during the operational use of the cartridge. On the other hand, Kane mentioned the sheath flow and dispersion promoter insert 220 may be operable to provide a dispersion that has a mass median particle diameter of less than 1 micron and aerosol delivery rates of at least about 0.01 mg/cm.sup.3, the sheath air causes the dispersion to supersaturate and nucleate to form new particles. The faster the dispersion is cooled the smaller the final diameter of the aerosol particles. However, a person having ordinary skill in the art would know that having a second expected volumetric airflow rate through the dilution air passage that is in a ratio of about 60:40 during the operational use of the cartridge is obvious matter of design choice desire to further enhance the quality of the aerosol amount discharge to the users. Further, since applicant has not disclosed the limitation above would solves any stated problem or is for any particular purpose and it appear that the invention would perform equally well with the prior art of record. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claim invention to further modify the cartridge of Kane by having a second expected volumetric airflow rate through the dilution air passage that is in a ratio of about 60:40 during the operational use of the cartridge as taught by the instant invention to further enhance the quality of the aerosol amount discharge to the users. As pr claim 11: Kane discloses the cartridge 70, and the airflow restrictor 33. However, Kane does not disclose wherein the airflow restrictor has a first cross-sectional flow area that is about 5-25% as large as a second cross-sectional flow area of the first portion of the air passage. On the other hand, Kane mentioned wherein the transverse channel 33 at a backside portion of the gasket 15 may intersect and communicate with the central channel 20 of the gasket 15. This transverse channel 33 assures communication between the central channel 20 and a space 35 defined between the gasket 15 and a cathode connector piece 37. However, a person having ordinary skill in the art would know that having the airflow restrictor has a first cross-sectional flow area that is about 5-25% as large as a second cross-sectional flow area of the first portion of the air passage can only deal with change in size, because such modification still would not change the function of the cartridge after all but to further enhance the flowing of the aerosol to the discharge end. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claim invention to further modify the cartridge of Kane by having the airflow restrictor has a first cross-sectional flow area that is about 5-25% as large as a second cross-sectional flow area of the first portion of the air passage as taught by the instant invention to further enhance the flowing of the aerosol to the discharge end.
