DETAILED ACTION
1. This office action is in response to Application No. 18044842 filed on 06/18/2026. Claims 1-19 are presented for examination and are currently pending. Applicant’s arguments have been carefully and respectfully considered.
Response to Arguments
2. Applicant’s arguments regarding the prior art rejection are moot in view of the
new grounds of rejection. The Examiner is withdrawing the rejections in the previous
Office Action because the Applicant’s amendments necessitated the new grounds of
rejection presented in this Office Action.
However, Huang, Liu, Li and Luo which was used previously in the art rejection is still relevant and applied.
The dependent claims 2-17, which depend directly or indirectly from independent claims 1, 18 and 19 are not patentable because the instant claims are still obvious over the prior art of record.
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 spatial attention layer learns to apply weighted mask to the input feature maps (pg. 67203, left col., last para.); The two connected residual modules output the
attention maps, which contains spatial information, pg. 67203, right col., last para.);
wherein the content attention layer (Global Attention Branch, Fig. 2) and the position attention layer (Local Attention Branch, Fig. 2) configured to operate in parallel with each other (see Fig. 2), and
wherein the machine-learned model is configured to perform operations comprising: receiving a layer input (pre-trained fully convolutional neural network on ImageNet …, which con-sists of the first five convolution blocks (i.e., Conv1-Conv5 in Fig.2), pg. 67203, left col., second para.) comprising input data that comprises a plurality of content values each associated with one or more context positions (600 x 600 pixels, pg. 67205, left col., last para. The Examiner notes context positions of content are pixels of an image, and each pixel has an associated content value);
generating, by the content attention layer (Global Attention Branch, Fig. 2), one or more output features (After the weight factor acts on the feature map, then a
global attention feature … for the cth channel is obtained via the second GAP layer, pg. 67203, left col., first para.) for each context position based on a global attention operation applied to the content values-independent of the context positions (In the first GAP layer, the values of different channels can be regarded as the
global context information of the image via global average pooling … pg. 67202, last para. Left col., to right col., first para. The Examiner notes the output features for each context position generated based on the global attention is independent of the positions);
and determining a layer-output (softmax layer, Fig. 2), based at least in part on the one or more output features for each context position generated by the content attention layer and the attention map generated for each context position by the positional attention layer (global, local feature vectors and their concatenation in the softmax layer of this network (pg. 67204, left col., last para., Fig. 2); During each training… local, global, and their concatenated features using softmax, abstract).
Guo does not explicitly teach generating, by the positional attention layer, an attention map for each of the context positions based on one or more of the content values associated with the respective context position and a neighborhood of context positions relative to the respective context position, the positional attention layer comprising at least a column-focused attention sublayer that attends to context positions along a column of each respective context position and a row-focused attention sublayer that attends to context positions along a row of each respective context position;

generating, by the positional attention layer, an attention map for each of the context positions based on one or more of the content values associated with the respective context position (The proposed PiCANet simultaneously generates an attention map at each pixel over its context region, pg. 2, left col., first para. the Examiner notes each pixel is context position that has a content value at each pixel) and
a neighborhood of context positions relative to the respective context position (Thus, we enable each pixel (w, h) to “see” the local neighbouring region F¯w,h ∈ RW¯×H¯×C centered at it. pg. 4, left col., first para. The Examiner notes the neighboring region of a pixel is a neighborhood of context positions),
the positional attention layer comprising at least a column- focused attention sublayer that attends to context positions along a column of each respective context position (Next, the ReNet uses another two LSTMs to scan each column of the obtained feature map in both bottom-up and top-down orders, pg. 3, right col., second para.
