It is submitted that it would have been a routine matter of design choice to modify the system of Yan et al. such that it comprises the sensor being positioned in the anaerobic region and the system being configured to dose the organic carbon into the anaerobic region in order to, for example, be able to control denitrification conditions in the anaerobic region, depending on anticipated contaminant loading and the results desired. It has been held that routine matters of design choice do not involve an inventive step. See MPEP 2144.
Per claim 14, Yan et al. disclose the subjecting step comprising:
forming an anaerobic region (3) and an anoxic region (4); and utilizing continuous flow, cyclic aeration (page 6, aeration of the aerobic processing cell constant is 200L/h; page 6, the PLC computer automatic control system 19 increases the aeration rate to 2 times of the original air pump 7, to increase the dissolved oxygen concentration in the aerobic treatment tank 5,);

Yan et al. do not disclose detecting N2O in the anaerobic region and dosing the organic carbon into the anaerobic region.
It is submitted that it would have been a routine matter of design choice to modify the method of Yan et al. such that it comprises detecting N2O in the anaerobic region and dosing the organic carbon into the anaerobic region in order to, for example, be able to control denitrification conditions in the anaerobic region, depending on anticipated contaminant loading and the results desired. It has been held that routine matters of design choice do not involve an inventive step. See MPEP 2144.
Claims 7 and 17 are rejected under 35 U.S.C. 103 as being unpatentable over Yan et al. (‘092) in view of Van Nieuwenhuijzen (WO 2019/132655).
Per claim 7, Van Nieuwenhuijzen does not disclose further comprising at least one of a nitrite sensor and a nitrate sensor positioned in the basin, the wastewater treatment system being further configured to dose organic carbon from the organic carbon source to the biological treatment based on a reading of the at least one of the nitrite sensor and the nitrate sensor.
