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.
Claims 1-3, 5 and 7-8 are rejected under 35 U.S.C. 103 as being unpatentable over Paul et al. (“Assessing the soil quality of Bansloi river basin, eastern India using soil-quality indices (SQIs) and Random Forest machine learning technique”) (hereinafter Paul) and in view of Chen et al. (“Minimum Data Set for Assessing Soil Quality in Farmland of Northeast China”) (hereinafter Chen).
Regarding Claim 1,
Paul teaches:
“An ensemble learning-based optimized evaluation method for an improvement effect of organic materials on soil quality, comprising following steps:” (Paul, Sections 2.1 and 2.8, “Crop productivity as well as the use of organic fertilizer is relatively low than the state average […] Therefore, through assessment of the soil quality is one of the prime needs for sustaining the agricultural productivity of the region […] In the present study we implemented a Random Forest (RF) model (Conoscenti et al., 2008; Gayen et al., 2019; Tsangaratos et al., 2017) in the prediction of spatial soil quality index using the RF 4.6 package in the R environment.”; Examiner’s note: a Random Forest (RF) teaches an ensemble learning-based optimized evaluation method. The use of organic fertilizer and the assessment of the soil quality teach improvement effect of organic materials on soil quality.)
“formulating an overall framework” (Paul, Section 2.8, “In this spatial soil quality prediction framework, as spatial covariates, eleven land quality and ecological vectors are preliminarily selected as candidates of auxiliary (or predictor) variables.”; Examiner’s note: formulating an overall framework (i.e., formulating a spatial soil quality prediction framework) is taught.)
“developing a soil quality prediction model based on machine learning” (Paul, Section 2.8, “In the present study we implemented a Random Forest (RF) model (Conoscenti et al., 2008; Gayen et al., 2019; Tsangaratos et al., 2017) in the prediction of spatial soil quality index using the RF 4.6 package in the R environment.”; Examiner’s note: developing a soil quality prediction model based on machine learning (i.e., implementing a random forest (RF) model in the prediction of spatial soil quality) is taught.)
“generating a soil quality extended dataset and a soil quality evaluation dataset” (Paul, Section 4, “Addition of more number of sampling points to the training dataset could help to improve the accuracy of predictions. The current work refers to topsoil (0–20 cm depth), but subsoil dataset (i.e. beyond 20 cm of depth) including the soil C horizon in weathering substrate could be incorporated.”; Examiner’s note: generating a soil quality extended dataset (i.e., incorporating subsoil dataset into topsoil dataset) and a soil quality evaluation dataset (i.e., adding more sampling points to the training dataset to improve the accuracy of predictions) is taught.)
analyzing data in the soil quality extended dataset and the soil quality evaluation dataset by using the soil quality prediction model (Paul, Section 2.8, “three error criteria are used for evaluating the ability of the RF models in predicting the SQIs: namely the coefficient of determination (R2), mean error (MAE) and root mean square error (RMSE).”; Examiner’s note: analyzing data in the soil quality extended dataset and the soil quality evaluation dataset (i.e., evaluating the ability of the RF models in predicting the SQIs using the coefficient of determination (R2), mean error (MAE) and root mean square error (RMSE)) by using the soil quality prediction model (i.e., the random forest (RF) model) is taught.)
Paul does not explicitly teach:
“establishing a total dataset (TDS) and a minimum dataset (MIDS), and calculating soil quality indices based on the TDS and the MDS”
to evaluate improvement effect of organic materials on soil quality
Chen teaches:
“establishing a total dataset (TDS) and a minimum dataset (MIDS), and calculating soil quality indices based on the TDS and the MDS” (Chen, Calculation and classification of SQI in Page 567, “Each PC explained a certain amount of the variation in the total data set (TDS). The percentage of the variation divided by the total percentage of variation explained by all PCs with eigenvectors > 1 provided the weight based on variation of PCA. The weight of the TDS was calculated from the communality of the PCA. We then summed the weighted MDS variable scores for each observation. The final PCA-based soil quality equation is as follows:
PNG
media_image5.png

473
media_image5.png
Greyscale
where W is the PCA weighting and S is the indicator score.”; Chen, Calculation and classification of SQI in Page 571, “The indicators in the TDS or MDS were weighted based on results of the mathematical statistics (Table IV) […] Silt, clay, SOM, and TN had higher weights, whereas Bd had the lowest weight in the TDS. The indicators had weights from 0.1 to 0.14 in the MDS.”;

; Examiner’s note: establishing a total dataset (TDS) (i.e., TDS in table IV teaches a total dataset) and a minimum dataset (MIDS) (i.e., MDS in table IV teaches a minimum dataset), and calculating soil quality indices based on the TDS and the MDS (i.e., the final PCA-based soil quality equation in (4)) is taught.)
to evaluate improvement effect of organic materials on soil quality (Chen, Descriptive statistics of soil characteristics and yield in Page 568, “The soils were considered rich in organic matter, with mean SOM values of 48.0 g kg−1. This was considerably higher than for soils in other areas of China, including Hainan, Anhui, and Sichuan Provinces where SOM values averaged 20, 23, and 12 g kg−1, respectively (Cao and Zhou, 2008) […] The high nutrient and SOM levels confirmed that farmland in Hailun County was indeed quite fertile.”; Examiner’s note: to evaluate improvement effect of organic materials on soil quality (i.e., SOM values of 48.0 g kg-1 in Hailun County, the high nutrient and SOM levels confirming that farmland in Hailun County quite fertile) is taught.)
It would have been obvious to one of ordinary skill in the art before the effective filing date of the present application to combine the soil quality assessment using soil-quality indices (SQIs) and random forest machine learning technique in Paul, and the minimum data set for assessing soil quality as taught in Chen. Paul teaches formulating an overall framework, developing a soil quality prediction model, generating a soil quality extended dataset and a soil quality evaluation dataset, and analyzing data in the soil quality extended dataset and the soil quality evaluation dataset by using the soil quality prediction model. Chen teaches establishing a total dataset (TDS) and a minimum dataset (MIDS), calculating soil quality indices, and evaluating improvement effect of organic materials on soil quality. One of ordinary skill would have motivation to combine Paul and Chen so that “soil quality indices could be effectively used to evaluate agricultural land and crop response using a variety of different weighting methods” (Chen, Conclusions in Page 574).
Regarding Claim 2,
The combination of Paul and Chen teaches:
“The ensemble learning-based optimized evaluation method according to claim 1,” (preamble)
“wherein in step S1, the overall framework comprises: establishment of the TDS and calculation of a soil quality index based on the TDS, establishment of the MDS and calculation of a soil quality index based on the MDS, development of the soil quality prediction model based on the machine learning, and generation of the soil quality evaluation dataset” (Chen, Calculation and classification of SQI in Page 567, “Each PC explained a certain amount of the variation in the total data set (TDS). The percentage of the variation divided by the total percentage of variation explained by all PCs with eigenvectors > 1 provided the weight based on variation of PCA.

where W is the PCA weighting and S is the indicator score.”; Chen, Indicator selection in Page 569, “Our approach established an MDS from soil quality indicators that were able to mainly show effects as a result of agriculture management practices. Therefore, as many as 20 physical and chemical indicators were chosen for our TDS. The 20 soil quality properties considered in the PCA were grouped into components. The first seven PCs had eigenvalues > 1, each explaining at least 5% of the data variation and accounting for 74.9% of the total variance (Table II).”; Chen, Calculation and classification of SQI in Page 572, “The SQIs were calculated using Eq. 4 and then ranked with the grades of each method shown in Table V, which showed that classification criteria for SQI based on TDS (SQI-TDS), SQI based on MDS (SQI-MDS) calculated from norm (SQIMDSnorm), SQI-MDS calculated from communality (SQI-MDScommunality), and SQI-MDS calculated from regression (SQI-MDSregression) were almost the same.”;

The air-dried samples were crushed and passed through a 2-mm (10 meshes) or 0.149-mm (100 meshes) sieve to determine its different attributes […] Each soybean sample was collected within a 2 m2 around the corresponding soil sampling site. The three soybean subsamples were collected, dried and weighed.”; Chen, Indicator selection in Page 566, “[…] the selection of MDS indicators relied primarily on expert opinion (Doran and Parkin, 1994; Larson and Pierce, 1994). However, selection of MDS variables can be simplified using statistical methods, such as PCA (Andrews and Carroll, 2001; Rezaei et al., 2005), factor analysis, and/or regression equations (Masto et al., 2008). We employed PCA as a data reduction tool to select the most appropriate indicators of site potential for the study area.”; Chen, Indicator scoring in Page 567, “In our study, the data of selected indicators were scored through the linear technique according to Diack and Stott (2001).”; Chen, Calculation and classification of SQI in Page 567, “Each PC explained a certain amount of the variation in the total data set (TDS).
