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 of this title, 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 2 is rejected under 35 U.S.C. 103 as being unpatentable over NGUYEN et al. (US 12118723 B1), hereinafter referenced as NGUYEN in view of GAMAGE et al. (Gamage L, Isuranga U, Meedeniya D, De Silva S, Yogarajah P. Melanoma Skin Cancer Identification with Explainability Utilizing Mask Guided Technique. Electronics. January 2024; 13(4):680. https://doi.org/10.3390/electronics13040680), hereinafter referenced as GAMAGE. Regarding claim 2, NYUGEN explicitly teaches a method of analyzing digital dermoscopy images as recited in claim 1, although NYUGEN explicitly teaches further comprising generating a digital dermoscopy image, wherein the digital dermoscopy image represent differing degrees of likelihood of positive dermoscopy features associated with possible pre-malignant and/or malignant tissue or atypical melanocytic nevi (Fig. 23. Column [14], Lines [01-41]-NYUGEN discloses the 10 classifications and 122 sub-classes include: MEL: including all types of malignant melanoma such as melanoma in situ, superficial spreading melanoma, nodular melanoma, etc., BCC: including all types of basal cell carcinoma such as superficial basal cell carcinoma, nodular basal cell carcinoma, basosquamous carcinoma, ulcerated basal cell carcinoma, etc. EPI: including all types of epidermal pre-malignant and malignant tumors, MALO: This class contains Merkel cell carcinoma, kaposi sarcoma, dermatofibrosarcoma protuberans, etc. NV: including all types of melanocytic nevus and melanosis.

The risk level 122 can also include a risk level five indicating a high risk of invasive melanoma or other high grade skin cancers. Please also see claim 3, 10, 17 and read Column [03], Lines [12-18]). NYUGEN fails to explicitly teach further comprising generating a digital dermoscopy image heatmap overlay, wherein different colors shown in the digital dermoscopy image heatmap overlay represent differing degrees of likelihood of positive dermoscopy features. However, GAMAGE explicitly teaches further comprising generating a digital dermoscopy image heatmap overlay (Fig. 20. Page [02], Paragraph [02]-GAMAGE discloses this study presents a computational model for melanoma identification using a deep learning model with transfer learning and XAI. The main focus of this study is to achieve high performance in skin image classification and show the model’s explainability to increase the trustworthiness of the proposed solution. The explainable heatmaps are based on gradient-weighted class activation mapping (Grad-CAM) [7] and Grad-CAM++ [8]. At page [23], Paragraph [01]-GAMAGE discloses we have deployed the proposed model as a support tool named LU Bio Vision and a sample GUI is shown in Figure 20. The web application provides a user-friendly interface to test a skin image for melanoma conditions. The application allows to upload a skin image. Here, the user can select the proposed CNN model or the ViT-based model to classify the image. Then the system generates the corresponding heatmaps together with the predicted class with the accuracy probability. Additionally, users can generate and download the medical report in PDF format with dermatologist feedback (wherein the HAM10000 and ISIC datasets are used for model training, which contains dermoscopic images for 7 categories of skin lesions, including Nevi and melanoma, and dermoscopic attribute masks for pigment networks, negative network, streaks, and globules). Please also see Fig. 2 and 17), wherein different colors shown in the digital dermoscopy image heatmap overlay represent differing degrees of likelihood of positive dermoscopy features (Fig. 17. Page [20], Paragraph [01]-GAMAGE discloses these results affirm the performance improvements of our SM-ViT model when compared to the baseline ViT model, highlighting its effectiveness in accurately classifying melanoma and underscoring its potential for enhancing medical image identification tasks. Both the SM-ViT and Baseline ViT models have demonstrated higher accuracy in identifying Nevi lesions compared to melanoma. Therefore, both models exhibit good sensitivity when it comes to Nevi detection. Further at Page [20], Paragraph [02]-GAMAGE discloses we generated heatmaps for the images utilizing XAI techniques, namely, Grad-CAM and Grad-CAM++. At Page [20], Paragraph [03]-GAMAGE discloses we evaluated the performance of our model against ground truth and generated maps using the ISIC 2017 binary mask dataset and ISIC 2018 attribute mask dataset. The color range in the explainable heatmap indicates the regions that have contributed more and less to the classification, using red and blue, respectively. The attribute masks corresponding to each image are also used to validate the explanations by comparing them with the predicted heatmap outputs. Please also see Fig. 2 and 20). PNG media_image4.png 209 822 media_image4.png Greyscale FIGURE 17 illustrates a comparison of explainability heat maps using neural network models and a color range for quantifying the contributions of areas. PNG media_image5.png 899 943 media_image5.png Greyscale FIGURE 2 illustrates a high-level architecture for melanoma/nevi identification that uses artificial intelligence models (e.g. a CNN) for classification, multiple diverse training databases (e.g. ISIC, HAM10000) containing dermoscopic images and color coded heat maps for explaining the level of contribution to each classification. PNG media_image6.png 964 933 media_image6.png Greyscale FIGURE 20 illustrates a report generated for a skin lesion with explainability heatmaps using a support tool named LU Bio Vision and a sample GUI. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention was made to combine the teachings of NGUYEN of having a method of analyzing digital dermoscopy images, with the teachings of GAMAGE of having further comprising generating a digital dermoscopy image heatmap overlay, wherein different colors shown in the digital dermoscopy image heatmap overlay represent differing degrees of likelihood of positive dermoscopy features. Wherein NGUYEN’s method having further comprising generating a digital dermoscopy image heatmap overlay, wherein different colors shown in the digital dermoscopy image heatmap overlay represent differing degrees of likelihood of positive dermoscopy features associated with possible pre-malignant and/or malignant tissue or atypical melanocytic nevi of uncertain malignant potential. The motivation behind the modification would have been to obtain a method that improves the analysis of skin lesions and detection of skin cancer, since both NGUYEN and GAMAGE concern skin lesion detection and dermoscopy image analysis. Wherein NGUYEN’s provides improves the automatic detection of skin cancer using deep learning and image analysis, while GAMAGE’s systems and methods provide improvements to the training and accuracy of machine learning models for skin lesion detection.

Paragraph [0078]-MISHRA discloses the method includes diagnosing irregular or atypical pigment network (APN), which may have pigment network whose structure varies in size and/or shape. For example, irregular wide or dark APN aberrations may appear as a brown mesh, a black mesh, a gray mesh, and/or thick lines in dermoscopy images (wherein APN may extract morphological features, color features, and texture features, which includes a uniformity index and extracting color features of includes extracting average intensity and standard deviation of red, green and blue). Further in paragraph [0071]-MISHRA discloses as shown in FIGS. 3A-3C, the method is configured to capture varied and/or radial symmetry of colors (e.g., brown colors) on an image (e.g., FIG. 3A). In paragraph [0085]-MISHRA discloses the method includes identifying white and/or scar-like depigmented areas, such as ones that may represent the process of regression, such as ones that are indicators (e.g., important) of melanoma and other skin cancers, such as indicators of a response of the immune system to melanoma and other skin cancers. The method includes detecting hypopigmented areas that are peripheral and/or symmetric, which may be characteristic of benign lesions, such as of a dysplastic nevus. Please also read paragraph [0082-0084, 0086-0093, and 0156-0159]), irregular dots and globules (Fig. 9. Paragraph [0144]-MISHRA discloses determining white area features includes determining white area globule features (e.g., by running a globule feature code), which may include determining a binary feature mask, determining a lesion centroid co-ordinate, and determining lesion area. In certain embodiments, automatically detecting white area within a lesion includes determining an average eccentricity feature, a relative size of all white areas compared to lesion area, a relative size of largest white area compared to lesion area, an absolute size of the largest white area, a number of marked white areas per unit lesion area, an average border irregularity of all white areas, and/or a white area dispersement index. The white area globule features are also computed inside the lesion and outside the lesion separately. Please also read paragraph [0078, 0128, and 0156-0159]), regression patterns, and combinations thereof (Fig. 9. Paragraph [0103]-MISHRA discloses the method includes using the feature vectors of each of the six image processing modules including median split of colors, atypical pigment network, salient points, white color, pink colors, and vascular blush, along with the features from the clinical information module to create seven individual logistic regression models, which may include determining a binary feature mask, determining a lesion centroid co-ordinate, and determining lesion area. Further in paragraph [0152]-MISHRA discloses determining white area features includes applying a logistic regression or logistic model or logit model, such as to help generate a best-f it model to differentiate melanoma and other skin cancers from benign lesions). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention was made to combine the teachings of NGUYEN in view of MISHRA of having a method of analyzing digital dermoscopy images, with the teachings of MISHRA of having wherein the determination of the potential showing of the pre-malignant or malignant skin lesion or the atypical melanocytic nevus of uncertain malignant potential further comprises feature extraction from the digital dermoscopy image, wherein features are analyzed by the artificial intelligence system or the augmented intelligence system for a presence of parameters selected from the group consisting 1 of asymmetry, atypical network, blue-white-grey-violet structures, radial streams, pseudopods, irregular diffuse pigmentation, irregular dots and globules, regression patterns, and combinations thereof. Wherein NGUYEN’s method having wherein the determination of the potential showing of the pre-malignant or malignant skin lesion or the atypical melanocytic nevus of uncertain malignant potential further comprises feature extraction from the digital dermoscopy image, wherein features are analyzed by the artificial intelligence system or the augmented intelligence system for a presence of parameters selected from the group consisting 1 of asymmetry, atypical network, blue-white-grey-violet structures, radial streams, pseudopods, irregular diffuse pigmentation, irregular dots and globules, regression patterns, and combinations thereof. The motivation behind the modification would have been to obtain a method that improves the analysis of skin lesions and detection of skin cancer, since both NGUYEN and MISHRA concern skin lesion detection and dermoscopy image analysis. Wherein NGUYEN’s systems and methods improves the automatic detection of skin cancer using deep learning and image analysis, while MISHRA’s systems and methods improve the identification of melanoma and other skin cancer in a dermoscopy images using machine learning models. Please see NGUYEN et al. (US 12118723 B1), Abstract and MISHRA et al. (US 20210209754 A1), Abstract and Paragraph [0059-0063]. Regarding claim 4, NYUGEN in view of MISHRA explicitly teaches the method of analyzing digital dermoscopy images as recited in claim 3, NYUGEN fails to explicitly teach wherein the irregular dots and globules comprise round and/or oval structures. However, MISHRA explicitly teaches wherein the irregular dots and globules comprise round and/or oval structures (Fig. 9. Paragraph [0144]-MISHRA discloses determining white area features includes determining white area globule features (e.g., by running a globule feature code), which may include determining a binary feature mask, determining a lesion centroid co-ordinate, and determining lesion area. In certain embodiments, automatically detecting white area within a lesion includes determining an average eccentricity feature, a relative size of all white areas compared to lesion area, a relative size of largest white area compared to lesion area, an absolute size of the largest white area, a number of marked white areas per unit lesion area, an average border irregularity of all white areas, and/or a white area dispersement index. The white area globule features are also computed inside the lesion and outside the lesion separately. Therefore, it would have been obvious to a person of ordinary skill in the art for the irregular dots and globules to comprise round and/or oval structures. Although MISHRA explicitly teaches detecting irregular dots and globules as well as the size, shape, radial symmetry/asymmetry and uniformity of skin lesion structures, MISHRA is silent on globules and irregular dots comprising round and/or oval structures. However, it is well-known that globules and irregular dots are defined as generally round and/or oval structures, including within the field of dermatology. Thus, by further defining irregular dots and globular structures to be in line with conventional understandings, the accuracy of skin lesion detection and diagnosis can be improved. Please also read paragraph [0078, 0128, and 0156-0159]). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention was made to combine the teachings of NGUYEN in view of MISHRA of having a method of analyzing digital dermoscopy images, with the teachings of MISHRA of having wherein the irregular dots and globules comprise round and/or oval structures. Wherein NGUYEN’s method having wherein the irregular dots and globules comprise round and/or oval structures. The motivation behind the modification would have been to obtain a method that improves the analysis of skin lesions and detection of skin cancer, since both NGUYEN and MISHRA concern skin lesion detection and dermoscopy image analysis. Wherein NGUYEN’s systems and methods improves the automatic detection of skin cancer using deep learning and image analysis, while MISHRA’s systems and methods improve the identification of melanoma and other skin cancer in a dermoscopy images using machine learning models.

Please see Fig. 7. Abstract. DAVIS et al. (US 20170143249 A1)- Reference imagery of dermatological conditions is compiled in a crowd-sourced database (contributed by clinicians and/or the lay public), together with associated diagnosis information. A user later submits a query image to the system (e.g., captured with a smartphone). Image-based derivatives for the query image are determined (e.g., color histograms, FFT-based metrics, etc.), and are compared against similar derivatives computed from the reference imagery. This comparison identifies diseases that are not consistent with the query image, and such information is reported to the user. Depending on the size of the database, and the specificity of the data, 90% or more of candidate conditions may be effectively ruled-out, possibly sparing the user from expensive and painful biopsy procedures, and granting some peace of mind (e.g., knowledge that an emerging pattern of small lesions on a forearm is probably not caused by shingles, bedbugs, malaria or AIDS). A great number of other features and arrangements are also detailed....…....................... Please see para. [0359]. Abstract. BANDIC et al.
