Claim Rejections - 35 USC § 102 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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claims 1-4, 6, and 8-10 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Friedman (U. S. Patent No. 10,525,285 B1). With respect to claim 1, Friedman disclosed a dose measuring device for a measurement of a radiation dose comprising: a radiation-sensitive measuring film (860); and a base body (870, 872), wherein the radiation-sensitive measuring film is wound onto the base body at least in certain areas (column 15, line 55 – column 16, line 15), and wherein the base body comprises a material having a density, which largely corresponds to a density of a particulate material to be treated (when the particulate material is the same as the material of the base body, which is another way to say it is an intended use). With respect to claim 2, Friedman disclosed the dose measuring device according to Claim 1, wherein the base body having at least one dimension, which is substantially similar to at least one dimension of the particulate material to be treated, and wherein the at least one dimension of the base body is within ±25% of a corresponding at least one dimension of the particulate material to be treated (the material or article worked upon by a structure being claimed does not impart patentability to the claims. See MPEP § 2115). With respect to claim 3, Friedman disclosed the dose measuring device according to Claim 1, wherein the base body has a cylinder-like section, wherein the radiation-sensitive measuring film is wound on the cylinder-like section (column 15, line 55 - column 16, line 15). With respect to claim 4, Friedman disclosed the dose measuring device according to Claim 1, wherein the base body has at least one guide section for guiding the radiation-sensitive measuring film during winding of the radiation-sensitive measuring film onto the base body, wherein the at least one guide section comprises two guide sections (870, 872), and wherein the radiation-sensitive measuring film lies between the two guide sections after winding the radiation-sensitive measuring film onto the base body. With respect to claim 6, Friedman disclosed the dose measuring device according to Claim 1, wherein the base body comprises a material, whose chemical structure is substantially similar to a chemical structure of the particulate material to be treated, and wherein the material of the base body has a chemical composition that matches the primary elemental constituents of the particulate material to be treated (the material or article worked upon by a structure being claimed does not impart patentability to the claims. See MPEP § 2115). With respect to claim 8, Friedman disclosed the dose measuring device according to Claim 1, wherein a number of windings of the radio-sensitive measuring film on the base body corresponds to 1 to 20 (column 15, line 55 - column 16, line 15). With respect to claim 9, Friedman disclosed the dose measuring device according to Claim 1, further comprising at least one first fixing means for fixing a first end of the radiation-sensitive measuring film on the base body (the first end is attached to the base body as shown in FIG. 8A). With respect to claim 10, Friedman disclosed the dose measuring device according to Claim 1, further comprising at least one second fixing means for fixing a second end of the radiation-sensitive measuring film (the second end is attached to the base body as shown in FIG. 8A). Allowable Subject Matter Claims 5, 7, and 11-14 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.

Applicant’s amendments filed 10 November 2025 with respect to claims 5, 7, 8, and 11-14 have been fully considered. The rejection of claims 5, 7, 8, and 11-14 under 35 U.S.C. 112(b) or pre-AIA 35 U.S.C. 112, second paragraph, has been withdrawn. Applicant’s amendments filed 10 November 2025 with respect to claims 2 and 6 have been fully considered. The rejection of claims 2 and 6 under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, fourth paragraph, has been withdrawn. Response to Arguments In response to applicant's argument that the references fail to show certain features of the invention, it is noted that the features upon which applicant relies (i.e., a density of a particulate material to be treated (e.g., grains or spices)) are not recited in the rejected claims. Although the claims are interpreted in light of the specification, limitations from the specification are not read into the claims. See In re Van Geuns, 988 F.2d 1181, 26 USPQ2d 1057 (Fed. Cir. 1993). Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Friedman (U. S. Patent No. 11,027,152 B1) disclosed an ionizing-radiation beam monitoring system. Friedman (U. S. Patent No. 10,828,513 B2) disclosed an ionizing-radiation beam monitoring system. Liu et al. (U. S. Patent No. 10,379,227 B2) disclosed a radiation dose measuring method. Calvert et al. (U. S. Patent No. 6,979,829 B2) disclosed devices and methods for determining an amount of energy absorbed during an irradiation. THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
