Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL. —The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claim 13 is rejected under 35 U.S.C. 112(a) or pre-AIA 35 U.S.C. 112, first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Claim 13 recites a limitation “a control remote system” in line 2. However, the specification fails to describe a structure and a function of a control remote system. Therefore, the claim contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Allowable Subject Matter The following is a statement of reasons for the indication of allowable subject matter: With respect to claims 1-9, Donahue et al. (U. S. Patent No. 5,637,876 A) disclosed a device comprising: at least one light source (24); a radiosensitive film (10) (column 6, lines 20-39); and an optical sensor system (34) (column 6, line 63 - column 7, line 18). However, the prior art failed to disclose or fairly suggested a device comprising: a reflection film having an inner face and an outer face opposite to the inner face, the inner face being adapted to reflect light; at least one light source arranged to emit at least one light beam towards the inner face of the reflection film; a radiosensitive film having a first face facing the inner face of the reflection film and a second face opposite to the first face; an optical sensor system having a first face facing the second face of the radiosensitive film and adapted to receive the at least one light beam from the at least one light source after a reflection from the inner face of the reflection film, the optical sensor system further having a support layer and a second face opposite to the first face, wherein the first face of the optical sensor system comprises a 2-D array of one or more photoresistor units and/or semiconductor units, the 2-D array of one or more photoresistor units and/or semiconductor units being fixed to the support layer; wherein the reflection film, the radiosensitive film, and the 2-D array of one or more photoresistor units and/or semiconductor units are essentially parallel, and wherein the at least one light source is not located between the inner face of the reflection film and the first face of the radiosensitive film. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant’s disclosure. Enger et al. (U. S. Patent No. 11,656,369 B2) disclosed a radiation dosimeter.
