DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. Information Disclosure Statement The information disclosure statement (IDS) submitted on 11 October 2023 and 19 September 2024 were filed prior to the mailing date of th is office correspondence . The submission is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Specification Applicant is reminded of the proper language and format for an abstract of the disclosure. The abstract should be in narrative form and generally limited to a single paragraph on a separate sheet within the range of 50 to 150 words in length. The abstract should describe the disclosure sufficiently to assist readers in deciding whether there is a need for consulting the full patent text for details. The language should be clear and concise and should not repeat information given in the title. It should avoid using phrases which can be implied, such as, “The disclosure concerns,” “The disclosure defined by this invention,” “The disclosure describes,” etc. The application Abstract includes the phrase “ According to the invention ”. In addition, the form and legal phraseology often used in patent claims, such as “means” and “said,” should be avoided. Claim Objections Claims 1, 4 and 7 are objected to because of the following informalities: In claims 1, 4, and 7 : “ volatile, organic components ” should read: -- volatile organic components -- Appropriate correction is required. Claim Rejections - 35 USC § 103 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 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. Claim(s) 1 and 3-4 are rejected under 35 U.S.C. 103 as being unpatentable over Yuichiro ( WO 2018038068 ) in view of Ding (US 20130105999) . 3481959 2143354 measuring element sinks 0 0 measuring element sinks 3062173 2282342 0 0 3456686 62967 measuring element 0 measuring element 2871978 204825 0 0 3970655 1092835 sensor body 0 sensor body 3569284 1232738 Annotated Fig. 7 , Yuichiro .

The temperature at which the glass 30 solidifies upon cooling , the glass fixation point temperature is, for example, in the range of about 460 0 C to 510 0 C, and is typically 505 0 C , para. [00 14 ]) ; and E. after step D, cooling the sensor body so that the lead-free glass solder solidifies thereby connecting the at least one measuring element to the membrane of the sensor body ( strain sensor 100 is manufactured by bonding the semiconductor element 40 on the diaphragm 22 using molten glass and then cooling to solidify the glass 30 , para. [ 0014 ]) . 4045204 1209624 4461789 1066876 lead-free glass solder paste 0 lead-free glass solder paste Annotated Fig. 1, Ding. Yuichiro does not explicitly teach , the lead-free glass solder paste comprises glass particles and volatile organic components . However, Ding teaches a method of manufacturing a sensor body including providing a sensor body 102 and a measuring element 104 and a lead-free glass solder paste (glass frit adhesive 106, see annotated Fig. 1) or at least one lead-free molded glass part, wherein the lead-free glass solder paste comprises glass particles and volatile, organic components ( glass frit adhesive layer 106 is comprised of ground glass particles in a paste … screen printed on to the upper surface 110 of the substrate 102 and heated to burn off volatile solvents in the paste and to partially glaze the outside surface of the paste , para. [0011] ). Yuichiro teaches in para. [0014] strain sensor 100 is manufactured by bonding the semiconductor element 40 on the diaphragm 22 using molten glass and then cooling to solidify the glass 30 , and para.

Ding teaches in Fig. 1, a lead-free glass solder paste and heat ing to burn off volatile solvents in the paste . Therefore, Yuichiro in view of Ding teaches the recited structure (see the Note below) . Further, from the teaching of a partially sank measuring element 40 in Fig. 1B and placing a semiconductor element 40 over a molten glass 30 in para. [0014-0016] of Yuichiro , one of ordinary skill in the art would have known that “ measuring element sinks without an application of force ” as recited in lines 13 and 15, unless otherwise defined . Therefore, in view of the teachings of Ding , it would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the claimed invention, to modify the method of manufacturing of the sensor body of Yuichiro and to replace the molten glass paste 30 with a glass frit adhesive 106 as Ding taught in Fig. 1 so that it enables forming a strong bond between the measuring element and the sensor body as Ding disclosed in para. [0011]. Moreover, there is no indication in the instant invention that any surprising results were derived, or that any special steps were devised in providing the lead-free glass solder particles . Furthermore, the recited process steps of applying lead-free glass solder, applying the measuring element by which the product is made , are not necessarily done in the recited order, unless otherwise defined. Such a combination would have been done by one of ordinary skill in the art without any need for experimentation and with reasonable expectations of success. Note: Even though product-by-process claims are limited by and defined by the process, determination of patentability is based on the product itself. The patentability of a product does not depend on its method of production. If the product in the product-by-process claim is the same as or obvious from a product of the prior art, the claim is unpatentable even though the prior product was made by a different process. See MPEP § 2113 . Regarding claim 3 , Yuichiro in view of Ding teaches the recited limitations with respect to claim 1.

Ding teaches in Fig. 1, a lead-free glass solder paste and heating to burn off volatile solvents in the paste. Therefore, Yuichiro in view of Ding teaches the recited structure of the sensor body. Further, from the teaching of a partially sank measuring element 40 in Fig. 1B and placing a semiconductor element 40 over a molten glass 30 in para. [0014-0016] of Yuichiro , one of ordinary skill in the art would have known that “measuring element sinks without an application of force” as recited in lines 13 and 15, unless otherwise defined .

The particle-bearing paste is screen printed on to the upper surface 110 of the substrate 102 and heated to burn off volatile solvents in the paste and to partially glaze the outside surface of the paste, para. [0011]). F rom the teaching of a partially sank measuring element 40 in Fig. 1B and placing a semiconductor element 40 over a molten glass 30 in para. [0014-0016] of Yuichiro , one of ordinary skill in the art would have known that “measuring element sinks without an application of force” as recited in lines 13 and 15, unless otherwise defined .

Moreover, there is no indication in the instant invention that any surprising results were derived, or that any special steps were devised in re-heating the sensor body or re-solidifying the glass solder . Such a combination would have been done by one of ordinary skill in the art without any need for experimentation and with reasonable expectations of success.
