Drawings Figure 1 is objected to because reference number 41 is not directed to a material guide channel located inside an outer housing 40. The drawings are objected to as failing to comply with 37 CFR 1.84(p)(5) because they do not include the following reference sign(s) mentioned in the description: an outer housing 40, a mixing device 46, an electrical frame 140, and an electric cabinet 141. The drawings are objected to as failing to comply with 37 CFR 1.84(p)(5) because they include the following reference character(s) not mentioned in the description: 63. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action.

Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION. —The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of pre-AIA 35 U.S.C. 112, second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 5, 7, 8, and 11-14 are rejected under 35 U.S.C. 112(b) or pre-AIA 35 U.S.C. 112, 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. With respect to claim 5, the word "preferably" renders the claim indefinite because it is unclear whether the limitations following the phrase are part of the claimed invention. See MPEP § 2173.05(d). With respect to claim 7, the word "preferably" renders the claim indefinite because it is unclear whether the limitations following the phrase are part of the claimed invention. See MPEP § 2173.05(d). With respect to claim 8, the word "preferably" renders the claim indefinite because it is unclear whether the limitations following the phrase are part of the claimed invention. See MPEP § 2173.05(d). Claim 11 recites a limitation “the irradiated dose measuring devices” in line 7, which renders the claim indefinite. There is insufficient antecedent basis for the limitation in the claim. Claim 11 previously recites a limitation “several dose measuring devices” in line 4. Claim 11 recites a limitation “the irradiated measuring film” in line 8, which renders the claim indefinite. There is insufficient antecedent basis for the limitation in the claim. Claim 1 previously recites a limitation “a radiation-sensitive measuring film” in line 3. Claim 12 recites a limitation “the irradiated measuring film” in line 2, which renders the claim indefinite. There is insufficient antecedent basis for the limitation in the claim. Claim 1 previously recites a limitation “a radiation-sensitive measuring film” in line 3. With respect to claim 13, the word "preferably" renders the claim indefinite because it is unclear whether the limitations following the phrase are part of the claimed invention. See MPEP § 2173.05(d). With respect to claim 14, the word "preferably" renders the claim indefinite because it is unclear whether the limitations following the phrase are part of the claimed invention. See MPEP § 2173.05(d). The following is a quotation of 35 U.S.C. 112(d): (d) REFERENCE IN DEPENDENT FORMS.—Subject to subsection (e), a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. The following is a quotation of pre-AIA 35 U.S.C. 112, fourth paragraph: Subject to the following paragraph [i.e., the fifth paragraph of pre-AIA 35 U.S.C. 112], a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. Claims 2 and 6 are rejected under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends. Claims 2 and 6 fail to set forth an additional structural limitation of the dose measuring device. See Material or Article Worked Upon by Apparatus in MPEP § 2115. Applicant may cancel the claims, amend the claims to place the claims in proper dependent form, rewrite the claims in independent form, or present a sufficient showing that the dependent claims comply with the statutory requirements. 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 is fabricated from 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 has at least one dimension, which largely corresponds to 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 (870) 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 (two circular pieces), and wherein the radiation-sensitive measuring film lies between the two guide sections after winding the radiation-sensitive measuring film onto the base body (FIG. 8A). With respect to claim 6, Friedman disclosed the dose measuring device according to Claim 1, wherein the base body is fabricated from a material, whose chemical structure largely corresponds to a chemical structure 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 radiation-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).
