Claim 1 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 1 recites at lines 7-9 “upsampling a second derived feature, the second derived feature derived from the second feature derived from the second feature based on a layer included in a second type of path of the neural network--”. The above recital of the second derived feature derived from the second feature derived from the second feature, renders the claim indefinite. It is unclear as to how the second derived feature derived from the second feature derived from the second feature ?. Also it is unclear whether the second derived feature and from the second feature are same or different?. Amendments/clarification are required. Claims 2-13 depends from claim 1 are also rejected.
Claim 14 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 1 recites at lines 7-8 “upsampling a second derived feature, the second derived feature derived from the second feature based on a layer included in a second type of path of the neural network----”. The above recital of the second derived feature derived from the second feature, renders the claim indefinite. It is unclear as to how the second derived feature derived from the second feature?. Also it is unclear whether the second derived feature and from the second feature are same or different?. Amendments/clarification are required. Claims 15-20 depends from claim 14 are also rejected.
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.
