Claims 8-14 are rejected under 35 U.S.C. 101 because the claimed invention is directed to non-statutory subject matter. The claim does not fall within at least one of the four categories of patent eligible subject matter because the computer program product does not have a physical or tangible form (see MPEP 2106.03 I program per se, software per se). 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, 5-9, 11-17 and 19-20 are rejected under 35 U.S.C. 103 as being unpatentable over Jacob (US 20260118453 A1), hereinafter ‘Jacob’ in view of Burchard (US 20250209360 A1), hereinafter ‘Burchard’.
