DETAILED ACTION
Response to Amendment
The Amendment filed 3/24/2026 has been entered. Claims 1-4, 7-12 and 15-20 remain pending in the application. Claims 5-6 and 13-14 were cancelled.
Claim Objections
Claim 1, 7, 15 and 16 are objected to because of the following informalities:
Regarding claim 1, line 18, “the correction” should be “a correction” for clarity. And “a correction” in line 5 of claim 7 should be change into “the correction”, same issues for claims 15-16.
Regarding claim 7, “the correction factor comprises a quantity correction factor X, the quantity correction factor X being a quantity of finished products that allows for loss of the material” should be deleted, since claim 1 already include the same subject matter. Same issues for clam 15.
Appropriate correction is required.
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.
